JavaFX 12 maven and Spring - spring

I'm trying to add spring to my pom
but I'm wondering if my build will look like this.
Could someone help me how can I do this spring integration with java fx?

} }
I searched and found nothing about integrating javafx with spring
Could someone help me how I can integrate spring?
I tried to use what I used in my swing project but it didn't work out

Your main app has to maintain Spring's application context like this.
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.support.AbstractApplicationContext;
#Configuration // or #SpringBootApplication if you used spring boot.
public class App extends Application {
private static Scene scene;
private AbstractApplicationContext context;
#Override
public void init() throws Exception {
this.context = new AnnotationConfigApplicationContext(App.class);
super.init();
}
#Override
public void start(Stage stage) throws IOException {
SpringFxmlLoader loader = new SpringFxmlLoader(this.context);
Parent root = loader.loadFromResource("primary.fxml");
stage.setScene(new Scene(root));
stage.show();
}
public static void main(String[] args) {
launch();
}
}
use SpringFxmlLoader for returning a controller as a spring bean.
import java.io.IOException;
import java.io.InputStream;
import java.net.URL;
import org.springframework.context.ApplicationContext;
import javafx.fxml.FXMLLoader;
public class SpringFxmlLoader extends FXMLLoader {
private ApplicationContext context;
protected SpringFxmlLoader() {
}
public SpringFxmlLoader(ApplicationContext context) {
this.context = context;
setControllerFactory(context::getBean); // return a spring bean from spring's application context.
}
public ApplicationContext getContext() {
return this.context;
}
public <T> T loadFromResource(String resource) throws IOException {
return loadFromResource(resource, null);
}
public <T> T loadFromResource(String resource, Class<?> root) throws IOException {
URL resourceURL = context.getResource(resource).getURL();
setLocation(resourceURL);
if(root != null) setRoot(root);
try (InputStream fxml = resourceURL.openStream()) {
return load(fxml);
}
}
}
Your controller should be looked like this as a spring bean.
#Controller
#Scope("prototype")
public class PrimaryController {
#FXML private Parent rootView;
#FXML private TitledPane settingPane;
#Autowired private SomeBean someBean; // now you can autowire spring beans.
// braa....
}
Don't forget specify the controller class in your primary.fxml with fx:controller attribute.

Feign Client with Spring Cloud GatewayFilter cause cycle dependency

During certain checks, I need to make a request to my Microservice in the Gateway Filter.
When I define the Feign class in the GatewayFilter(my SecurityFilter.java) class, it gives the following error.
How can I resolve this situation.
Error:
Description:
The dependencies of some of the beans in the application context form a cycle:
┌─────┐
| securityFilter defined in file [/target/classes/com/example/SecurityFilter.class]
↑ ↓
| cachedCompositeRouteLocator defined in class path resource [org/springframework/cloud/gateway/config/GatewayAutoConfiguration.class]
↑ ↓
| routeDefinitionRouteLocator defined in class path resource [org/springframework/cloud/gateway/config/GatewayAutoConfiguration.class]
└─────┘
Action:
Despite circular references being allowed, the dependency cycle between beans could not be broken. Update your application to remove the dependency cycle.

#Component
public class SecurityFilter implements GatewayFilterFactory<SecurityFilter.Config> {
private final UserApi userApi;
public SecurityFilter(UserApi userApi) {

spring.main.allow-circular-references=true
private final UserApi userApi;
#Autowired
public SecurityFilter(#Lazy UserApi userApi) {
this.userApi = userApi;
}
This is how I was able to fix the problem by adding #Lazy.
If you intend to keep the circular dependency you can add this configuration
spring.main.allow-circular-references: true
I'm using #Lazy annotation whenever the feign client intent to be use, to avoid Circular Reference Error when using spring-cloud-gateway along with OpenFeign, even in my CustomGatewayFilter :)
#Component
public class CustomApiGatewayFilter extends AbstractGatewayFilterFactory<CustomApiGatewayFilter.Config> {
private static Logger logger = LogManager.getLogger(CustomApiGatewayFilter.class);
private final JwtConfig jwtConfig;
private final ThirdPartyFeignClientService thirdPartyFeignClientService;
public CustomApiGatewayFilter(JwtConfig jwtConfig, #Lazy ThirdPartyFeignClientService thirdPartyFeignClientService) {
super(Config.class);
this.jwtConfig = jwtConfig;
this.thirdPartyFeignClientService = thirdPartyFeignClientService;
}
....
....
}
And the usage of this feign client placed on a separate function used by this filter
private String validateToken(String jwtToken) throws MyAppException {
String json = "";
ObjectMapper mapper = new ObjectMapper();
try {
Claims claims = jwtConfig.getAllClaimsFromToken(jwtToken);
String additionalInfo = (String) claims.get("additionalInfo");
JwtPayload payload = mapper.readValue(additionalInfo, JwtPayload.class);
String username = jwtConfig.getUsernameFromToken(jwtToken);
if(thirdPartyFeignClientService.validateClient(payload.getClientId(), payload.getClientSecret())){
return username;
}else{
throw new MyAppException("Invalid Client", ErrorCode.GENERIC_FAILURE);
}
} catch (ExpiredJwtException e) {
logger.error(e.getMessage());
throw new MyAppException(e.getMessage(), ErrorCode.GENERIC_FAILURE);
} catch (Exception e) {
logger.error("Other Exception :" + e);
throw new MyAppException (e.getMessage(), ErrorCode.GENERIC_FAILURE);
}
}
And it works :)

AspectJ (Spring) + how to add the embedding of an aspect in a private method and get the specified data

I have created an aspect that should embed logging on methods marked with an annotation and with the private modifier.
In addition, I would like to add information to the log that will be available at the time of execution of the method (for example, the object with which the method works and the name of the method and the class with which it is currently working).

}
But at the moment I have no errors .
so far, I see that the aspect is embedded,
but I want it to be detailed so that the aspect is universal and I would not have to explicitly specify in the message in which class it works.
Maybe someone has ideas on how to fix it.
I suggest you to explore the AspectJ documentation and the JoinPoint API, too. Here is a little example in stand-alone AspectJ without Spring. You can adjust it to your needs:
package de.scrum_master.app;
public class Application {
public static void main(String[] args) {
Application application = new Application();
System.out.println(application.add(4, application.multiply(2, 3)));
application.divide(5, 0);
}
private int add(int i, int j) {
return i + j;
}
private int multiply(int i, int j) {
return i * j;
}
private double divide(int i, int j) {
return i / j;
}
}
package de.scrum_master.aspect;
import java.util.Arrays;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.AfterThrowing;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
#Aspect
public class MyAspect {
#Before("execution(private * *(..))")
public void beforeAdvice(JoinPoint joinPoint) {
System.out.println(joinPoint);
System.out.println(" Signature: " + joinPoint.getSignature());
System.out.println(" Target: " + joinPoint.getTarget());
System.out.println(" Arguments: " + Arrays.deepToString(joinPoint.getArgs()));
}
#AfterReturning(pointcut = "execution(private * *(..))", returning = "result")
public void afterReturningAdvice(JoinPoint joinPoint, Object result) {
System.out.println(" Result: " + result);
}
#AfterThrowing(pointcut = "execution(private * *(..))", throwing = "exception")
public void afterThrowingAdvice(JoinPoint joinPoint, Throwable exception) {
System.out.println(" Exception: " + exception);
}
}
Console log:

In addition to the context data I printed here, you can also get annotations and their properties, method parameter names (even though I think that is unnecessary and availability depends on compilation options) etc.

Spring annotation gives null value in my Spring MVC when I create JAX-RS Web service

I added JAX-RS Web service for my project .I want to get XML file. It works fine when I hard cord something on return statement and it works fine. But I want to get data from my database. I use
#Autowired
private ProductServices productServices;
for call Spring Service class... For other normal controllers this #Autowired working fine. In JAX-RS it doesn't works.
JAX-RS gives null value like this
I want to call this service for get data to my method. How can I do that..
This is my Model.
#Entity
#Table(name = "products")
#XmlRootElement
public class Product {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "product_id")
private long productId;
#NotNull

#NotNull
private int slsiUnit;
#NotNull
private String itemDesc;
#NotNull

}
public void setProductId(long productId) {
this.productId = productId;

}
public String getRecentUpdateBy() {

}
public void setRecentUpdateBy(String recentUpdateBy) {
this.recentUpdateBy = recentUpdateBy;
}
}
This is my Repository.
public interface ProductRepository extends CrudRepository<Product, Long> {

}
}
This is my JAX-RS Web Service class

public GenericResource() {
}
#GET
#Produces(MediaType.APPLICATION_XML)
public List<Product> getXml() {
List<Product> a = productServices.getProductList();
return a;
}
}
This is the MessageBodyWriter

Cucumber: no backend found when running from Spring Boot jar

I am creating a small testing framework that should utilize both Cucumber and the Spring Boot platform. The idea is to let the whole application be packaged as a single jar and run after the BDD features have been properly parametrized.
The framework starts in command line runner mode like this:
public class FwApplication implements CommandLineRunner {
public static void main(String[] args) {
SpringApplication.run(FwApplication.class, args);
}
#Override
public void run(String... arg0) throws Exception {
JUnitCore.main(CucumberIntegration.class.getCanonicalName());
}
}
Then there is the CucumberIntegration class:
#RunWith(Cucumber.class)
#CucumberOptions(features = "config/features")
#ContextConfiguration(classes= AppConfiguration.class)
public class CucumberIntegration {
}
I have also some simple tests which run fine under my IDE, but when I try to package the application and run it over java -jar fw-0.0.1-SNAPSHOT.jar I get to see following:
There was 1 failure:
1) initializationError(com.fmr.bddfw.test.CucumberIntegration)
cucumber.runtime.CucumberException: No backends were found. Please make sure you have a backend module on your CLASSPATH.
at cucumber.runtime.Runtime.<init>(Runtime.java:81)
at cucumber.runtime.Runtime.<init>(Runtime.java:70)
(...)
All necessary jars are already in the one jar created by maven and it works fine under my IDE.
Any ideas what could help?

Using the suggestion given by Marcus:
Step1: Create your custom MultiLoader class:
package cucumber.runtime.io;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
public class CustomMultiLoader implements ResourceLoader {
public static final String CLASSPATH_SCHEME = "classpath*:";
public static final String CLASSPATH_SCHEME_TO_REPLACE = "classpath:";
private final ClasspathResourceLoader classpath;
private final FileResourceLoader fs;
public CustomMultiLoader(ClassLoader classLoader) {
classpath = new ClasspathResourceLoader(classLoader);
fs = new FileResourceLoader();
}
#Override
public Iterable<Resource> resources(String path, String suffix) {
if (isClasspathPath(path)) {
PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
String locationPattern = path.replace(CLASSPATH_SCHEME_TO_REPLACE, CLASSPATH_SCHEME) + "/**/*" + suffix;
org.springframework.core.io.Resource[] resources;
try {
resources = resolver.getResources(locationPattern);
} catch (IOException e) {
resources = null;
e.printStackTrace();
}
return convertToCucumberIterator(resources);
} else {
return fs.resources(path, suffix);
}
}
private Iterable<Resource> convertToCucumberIterator(org.springframework.core.io.Resource[] resources) {
List<Resource> results = new ArrayList<Resource>();
for (org.springframework.core.io.Resource resource : resources) {
results.add(new ResourceAdapter(resource));
}
return results;
}
public static String packageName(String gluePath) {
if (isClasspathPath(gluePath)) {
gluePath = stripClasspathPrefix(gluePath);
}
return gluePath.replace('/', '.').replace('\\', '.');
}
private static boolean isClasspathPath(String path) {
if (path.startsWith(CLASSPATH_SCHEME_TO_REPLACE)) {
path = path.replace(CLASSPATH_SCHEME_TO_REPLACE, CLASSPATH_SCHEME);
}
return path.startsWith(CLASSPATH_SCHEME);
}
private static String stripClasspathPrefix(String path) {
if (path.startsWith(CLASSPATH_SCHEME_TO_REPLACE)) {
path = path.replace(CLASSPATH_SCHEME_TO_REPLACE, CLASSPATH_SCHEME);
}
return path.substring(CLASSPATH_SCHEME.length());
}
}
Step2: Create an adapter between org.springframework.core.io.Resource and cucumber.runtime.io.Resource:
package cucumber.runtime.io;
import java.io.IOException;
import java.io.InputStream;
public class ResourceAdapter implements Resource {
org.springframework.core.io.Resource springResource;
public ResourceAdapter(org.springframework.core.io.Resource springResource) {
this.springResource = springResource;
}
public String getPath() {
try {
return springResource.getFile().getPath();
} catch (IOException e) {
try {
return springResource.getURL().toString();
} catch (IOException e1) {
e1.printStackTrace();
return "";
}
}
}
public String getAbsolutePath() {
try {
return springResource.getFile().getAbsolutePath();
} catch (IOException e) {
return null;
}
}
public InputStream getInputStream() throws IOException {
return this.springResource.getInputStream();
}
public String getClassName(String extension) {
String path = this.getPath();
if (path.startsWith("jar:")) {
path = path.substring(path.lastIndexOf("!") + 2);
return path.substring(0, path.length() - extension.length()).replace('/', '.');
} else {
path = path.substring(path.lastIndexOf("classes") + 8);
return path.substring(0, path.length() - extension.length()).replace('\\', '.');
}
}
}
Step3: Create your custom main class that uses your CustomMultiLoader:
package cucumber.runtime.io;
import static java.util.Arrays.asList;
import java.io.IOException;
import java.util.ArrayList;
import cucumber.runtime.ClassFinder;
import cucumber.runtime.Runtime;
import cucumber.runtime.RuntimeOptions;
public class CucumberStaticRunner {
public static void startTests(String[] argv) throws Throwable {
byte exitstatus = run(argv, Thread.currentThread().getContextClassLoader());
System.exit(exitstatus);
}
public static byte run(String[] argv, ClassLoader classLoader) throws IOException {
RuntimeOptions runtimeOptions = new RuntimeOptions(new ArrayList<String>(asList(argv)));
ResourceLoader resourceLoader = new CustomMultiLoader(classLoader);
ClassFinder classFinder = new ResourceLoaderClassFinder(resourceLoader, classLoader);
Runtime runtime = new Runtime(resourceLoader, classFinder, classLoader, runtimeOptions);
runtime.run();
return runtime.exitStatus();
}
}
Step4: Call your custom main class instead of cucumber.api.cli.Main.main:
String[] cucumberOptions = { "--glue", "my.test.pack", "--no-dry-run", "--monochrome", "classpath:features" };
CucumberStaticRunner.startTests(cucumberOptions);
Fixed it by following configuration:
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<requiresUnpack>
<dependency>
<groupId>info.cukes</groupId>
<artifactId>cucumber-java</artifactId>
</dependency>
</requiresUnpack>
</configuration>
</plugin>
You should add cucumber-java dependency
<dependency>
<groupId>info.cukes</groupId>
<artifactId>cucumber-java</artifactId>
<version>${cucumber.version}</version>
</dependency>
private static byte run(String[] argv, ClassLoader classLoader) throws IOException {
// cucumber/Spring Boot classloader problem
// CucumberException: No backends were found. Please make sure you have a backend module on your CLASSPATH
RuntimeOptions runtimeOptions = new RuntimeOptions(new ArrayList<String>(asList(argv)));
ResourceLoader resourceLoader = new MultiLoader(classLoader);
ClassFinder classFinder = new ResourceLoaderClassFinder(resourceLoader, classLoader);
Reflections reflections = new Reflections(classFinder);
List<Backend> list = new ArrayList<>();
list.addAll(reflections.instantiateSubclasses(Backend.class, "cucumber.runtime", new Class[]{ResourceLoader.class}, new Object[]{resourceLoader}));
if (list.size() == 0) {
JavaBackend javaBackend = new JavaBackend(resourceLoader);
list.add(javaBackend);
}
Runtime runtime = new Runtime(resourceLoader, classLoader, list, runtimeOptions);
runtime.run();
return runtime.exitStatus();
}
I used below code in POM.xml file
<dependency>
<groupId>info.cukes</groupId>
<artifactId>cucumber-java</artifactId>
<version>1.2.4</version>
<scope>test</scope>
</dependency>
It is working fine now.

Spring boot - configure EntityManager

I was using Google guice in my project and now I tried to convert the framework to SpringBoot totally.
I configured the Bean for persistence.xml like below in
#Autowired
#Bean(name = "transactionManager")
public LocalContainerEntityManagerFactoryBean entityManagerFactory()
{
LocalContainerEntityManagerFactoryBean lEMF = new LocalContainerEntityManagerFactoryBean();
lEMF.setPersistenceUnitName("leaseManagementPU");
lEMF.setPersistenceXmlLocation("persistence.xml");
return lEMF;
}
Now I need to configure(Inject) EntityManager em, to do JPA operations like em.persist(), em.find etc... How do I configure, also someone try to explain this with sample code
With Spring Boot its not necessary to have any config file like persistence.xml. You can configure with annotations Just configure your DB config for JPA in the
application.properties
spring.datasource.driverClassName=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:#DB...
spring.datasource.username=username
spring.datasource.password=pass
spring.jpa.database-platform=org.hibernate.dialect....
spring.jpa.show-sql=true
Then you can use CrudRepository provided by Spring where you have standard CRUD transaction methods. There you can also implement your own SQL's like JPQL.
#Transactional
public interface ObjectRepository extends CrudRepository<Object, Long> {
...
}
And if you still need to use the Entity Manager you can create another class.
public class ObjectRepositoryImpl implements ObjectCustomMethods{
#PersistenceContext
private EntityManager em;
}
This should be in your pom.xml
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.2.5.RELEASE</version>

Hmmm you can find lot of examples for configuring spring framework. Anyways here is a sample
#Configuration
#Import({PersistenceConfig.class})
#ComponentScan(basePackageClasses = {
ServiceMarker.class,
RepositoryMarker.class }
)
public class AppConfig {
}
PersistenceConfig
#Configuration
#PropertySource(value = { "classpath:database/jdbc.properties" })
#EnableTransactionManagement
public class PersistenceConfig {
private static final String PROPERTY_NAME_HIBERNATE_DIALECT = "hibernate.dialect";
private static final String PROPERTY_NAME_HIBERNATE_MAX_FETCH_DEPTH = "hibernate.max_fetch_depth";
private static final String PROPERTY_NAME_HIBERNATE_JDBC_FETCH_SIZE = "hibernate.jdbc.fetch_size";
private static final String PROPERTY_NAME_HIBERNATE_JDBC_BATCH_SIZE = "hibernate.jdbc.batch_size";
private static final String PROPERTY_NAME_HIBERNATE_SHOW_SQL = "hibernate.show_sql";
private static final String[] ENTITYMANAGER_PACKAGES_TO_SCAN = {"a.b.c.entities", "a.b.c.converters"};
#Autowired
private Environment env;
#Bean(destroyMethod = "close")
public DataSource dataSource() {
BasicDataSource dataSource = new BasicDataSource();
dataSource.setDriverClassName(env.getProperty("jdbc.driverClassName"));
dataSource.setUrl(env.getProperty("jdbc.url"));
dataSource.setUsername(env.getProperty("jdbc.username"));
dataSource.setPassword(env.getProperty("jdbc.password"));
return dataSource;
}
#Bean
public JpaTransactionManager jpaTransactionManager() {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(entityManagerFactoryBean().getObject());
return transactionManager;
}
private HibernateJpaVendorAdapter vendorAdaptor() {
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
vendorAdapter.setShowSql(true);
return vendorAdapter;
}
#Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean() {
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
entityManagerFactoryBean.setJpaVendorAdapter(vendorAdaptor());
entityManagerFactoryBean.setDataSource(dataSource());
entityManagerFactoryBean.setPersistenceProviderClass(HibernatePersistenceProvider.class);
entityManagerFactoryBean.setPackagesToScan(ENTITYMANAGER_PACKAGES_TO_SCAN);
entityManagerFactoryBean.setJpaProperties(jpaHibernateProperties());
return entityManagerFactoryBean;
}
private Properties jpaHibernateProperties() {
Properties properties = new Properties();
properties.put(PROPERTY_NAME_HIBERNATE_MAX_FETCH_DEPTH, env.getProperty(PROPERTY_NAME_HIBERNATE_MAX_FETCH_DEPTH));
properties.put(PROPERTY_NAME_HIBERNATE_JDBC_FETCH_SIZE, env.getProperty(PROPERTY_NAME_HIBERNATE_JDBC_FETCH_SIZE));
properties.put(PROPERTY_NAME_HIBERNATE_JDBC_BATCH_SIZE, env.getProperty(PROPERTY_NAME_HIBERNATE_JDBC_BATCH_SIZE));
properties.put(PROPERTY_NAME_HIBERNATE_SHOW_SQL, env.getProperty(PROPERTY_NAME_HIBERNATE_SHOW_SQL));
properties.put(AvailableSettings.SCHEMA_GEN_DATABASE_ACTION, "none");
properties.put(AvailableSettings.USE_CLASS_ENHANCER, "false");
return properties;
}
}
Main
public static void main(String[] args) {
try (GenericApplicationContext springContext = new AnnotationConfigApplicationContext(AppConfig.class)) {
MyService myService = springContext.getBean(MyServiceImpl.class);
try {
myService.handleProcess(fromDate, toDate);
} catch (Exception e) {
logger.error("Exception occurs", e);
myService.handleException(fromDate, toDate, e);
}
} catch (Exception e) {
logger.error("Exception occurs in loading Spring context: ", e);
}
}
MyService
#Service
public class MyServiceImpl implements MyService {
#Inject
private MyDao myDao;
#Override
public void handleProcess(String fromDate, String toDate) {
List<Student> myList = myDao.select(fromDate, toDate);
}
}
MyDaoImpl
#Repository
#Transactional
public class MyDaoImpl implements MyDao {
#PersistenceContext
private EntityManager entityManager;
public Student select(String fromDate, String toDate){
TypedQuery<Student> query = entityManager.createNamedQuery("Student.findByKey", Student.class);
query.setParameter("fromDate", fromDate);
query.setParameter("toDate", toDate);
List<Student> list = query.getResultList();
return CollectionUtils.isEmpty(list) ? null : list;
}
}
Assuming maven project:
Properties file should be in src/main/resources/database folder
jdbc.properties file
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=your db url
jdbc.username=your Username
jdbc.password=Your password
hibernate.max_fetch_depth = 3
hibernate.jdbc.fetch_size = 50
hibernate.jdbc.batch_size = 10
hibernate.show_sql = true
ServiceMarker and RepositoryMarker are just empty interfaces in your service or repository impl package.
Let's say you have package name a.b.c.service.impl. MyServiceImpl is in this package and so is ServiceMarker.
public interface ServiceMarker {
}
Same for repository marker. Let's say you have a.b.c.repository.impl or a.b.c.dao.impl package name. Then MyDaoImpl is in this this package and also Repositorymarker
public interface RepositoryMarker {
}
a.b.c.entities.Student
//dummy class and dummy query
#Entity
#NamedQueries({
#NamedQuery(name="Student.findByKey", query="select s from Student s where s.fromDate=:fromDate" and s.toDate = :toDate)
})
public class Student implements Serializable {
private LocalDateTime fromDate;
private LocalDateTime toDate;
//getters setters
}
a.b.c.converters
#Converter(autoApply = true)
public class LocalDateTimeConverter implements AttributeConverter<LocalDateTime, Timestamp> {
#Override
public Timestamp convertToDatabaseColumn(LocalDateTime dateTime) {
if (dateTime == null) {
return null;
}
return Timestamp.valueOf(dateTime);
}
#Override
public LocalDateTime convertToEntityAttribute(Timestamp timestamp) {
if (timestamp == null) {
return null;
}
return timestamp.toLocalDateTime();
}
}
