What is the correct way to include and use JPA Entity Lifecycle Events when using spring-boot-starter-data-mongodb?
my pom.xml dependencies
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-rest</artifactId>

<artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
My classpath doesn't see to have any of the following JPA annotations:
#PrePersist
#PostPersist
#PreRemove
#PostRemove
#PreUpdate
#PostUpdate
#PostLoad
Mongo has its own events documented # #Entity Callbacks.
Example:
class DefaultingEntityCallback implements BeforeSaveCallback<Person>, Ordered {
#Override
public Object onBeforeSave(Person entity, String collection) {
if(collection == "user") {
return // ...
}
return // ...
}
#Override
public int getOrder() {
return 100;
}
}
Following Functional interfaces available:
org.springframework.data.mongodb.core.mapping.event.AfterConvertCallback
org.springframework.data.mongodb.core.mapping.event.AfterSaveCallback
org.springframework.data.mongodb.core.mapping.event.BeforeConvertCallback
org.springframework.data.mongodb.core.mapping.event.BeforeSaveCallback
org.springframework.data.mongodb.core.mapping.event.ReactiveAfterConvertCallback
org.springframework.data.mongodb.core.mapping.event.ReactiveAfterSaveCallback
org.springframework.data.mongodb.core.mapping.event.ReactiveBeforeConvertCallback

I am using spring-boot-starter-parent version 2.2.2.RELEASE with spring-cloud.version Hoxton.SR1 to create 2 services : ordercreate(Supplier) and orderconsume(Consumer).
In Consul, the 2 services are up as below
I get the exception
java.net.UnknownHostException: ordercreate
when invoking the orderconsumer service as below:
http://localhost:8282/consumeOrder
Please find the code details below.Thanks for suggestions.
ordercreate
pom.xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-consul-discovery</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
application.properties
spring.application.name=ordercreate
server.port=8181
OrderCreateController
#RestController
public class OrderCreateController {
#GetMapping("/createOrder")
public String createOrder() {
System.out.println("In Supplier...");
return "Hello consul";
}
}
For Consumer,
orderconsume
pom.xml
<dependency>

application.properties
spring.application.name=orderconsume

OrderConsumeApplication
#SpringBootApplication
#EnableDiscoveryClient
public class OrderConsumeApplication {
public static void main(String[] args) {
SpringApplication.run(OrderConsumeApplication.class, args);
}
}
OrderConsumeController
#RestController
public class OrderConsumeController {
#Autowired
private RestTemplate restTemplate;
//http://localhost:8282/consumeOrder
#GetMapping(value="/consumeOrder")
public String receiveOrder() {
String uri = "http://ordercreate/createOrder";
return restTemplate.getForObject(uri, String.class);
}
#Bean
public RestTemplate getRestTemplate() {
return new RestTemplate();
}
}
So, I have a problem like this:
2020-01-30 22:54:20.059 ERROR 8040 --- [ main] o.s.boot.SpringApplication : Application run failed

My repository:

Dieta findByName (String name);
}
And my Controller:
#RestController
public class DietaController {
#Autowired
private DietaRepository dietaRepository;
#GetMapping("/dieta")
public List<Dieta> getAllNotes() {
return dietaRepository.findAll();
}
}
Application java class:

#EntityScan ( basePackages = { " com.diet4you.LapkoEkaterina" })
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
remove space here #EntityScan ( basePackages = { " com.diet4you.LapkoEkaterina" }) between " and com.diet4you...
change extends JpaRepository<Dieta, String> to extends JpaRepository<Dieta, Integer>
remove or fix Dieta findByName (String name) at repository interface, it's mistake
When trying to autowire DataSource by using Spring Boot 2.0.2 RELEASE, it gives the following error and cannot manage to inject it:
'Could not autowire. There is more than one bean of 'DataSource' type.'
The beans are created in DataSourceConfiguration class for HikariDataSource, BasicDataSource and for Tomcat.
Is there a way of qualifying one of them and avoid creation of the remaining ones?
#EnableWebSecurity
#EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
public SecurityConfig() {
this.usersByUsernameQuery = // definitions here
this.authoritiesByUsernameQuery = //
this.allowedAuthorities = //
}
#Autowired
public void configureGlobal(final AuthenticationManagerBuilder auth, final DataSource dataSource) throws Exception {
auth.jdbcAuthentication()
.dataSource(dataSource)
.usersByUsernameQuery(usersByUsernameQuery)
.authoritiesByUsernameQuery(authoritiesByUsernameQuery);
}

I am new with spring boot, is very simple my question but I can´t find where is the problem.
I have a basic #GetMapping and #DeleteMapping
#RestController
public class MyController
{
private MyServiceImpl myService;
#Autowired
public MyController(MyServiceImpl myService)
{
this.myService = myService;
}
#GetMapping("/test")
public List<Scan> getTestData(#RequestParam(value = "test_id", required = true) String test_id) {
return myService.findByTestId( test_id );
}
#DeleteMapping("/test")
public int deleteData(#RequestParam(value = "test_id", required = true) String test_id){
return myService.deleteTest( test_id );
}
#DeleteMapping("/test2")
public String deleteArticle() {
return "Test";
}
}
I am testing with Postman, the Get request is working, but the delete request is not. Even when I debug the spring boot application. The GetMapping is called, whereas the delete is not "reacting" /called
Maybe is not enough information, but I even tested #DeleteMapping("/test2") is not doing anything, I mean, I get no response, and in Postman it stays "loading..."
Any suggestions?

}
As in SPR comments described SPR-16874:
it does not support DELETE currently. It would be a trivial change to
make. There is suggested a workaround:
#DeleteMapping(value = "/greeting")
public Greeting handle(#RequestBody MultiValueMap<String, String> params) {
return new Greeting(counter.incrementAndGet(),
String.format(template, params));
}
As you can see the issue has been opened in the spring boot tracker.
I'm not sure the best way to word this issue, because I have no idea why this happens.
When I start up my Spring Boot application without the spring-integration-core jar, my app starts up fine. The second I add the spring-boot-starter-integration or any spring-integration-core library to my Maven pom file the servlet context is always null on my DelegatingWebMvcConfiguration class and I get the following error:
java.lang.IllegalArgumentException: A ServletContext is required to configure default servlet handling
After doing some debugging, I see the DelegatingWebMvcConfiguration class initialized before the EmbeddedWebApplicationContext sets the servlet context for my application, which makes sense why the servlet context is null for my DelegatingWebMvcConfiguration and set for all the other classes initialized with postProcessBeforeInitialization in ServletContextAwareProcessor. Simply removing the Spring Integration dependency fixes the issue, but I'd like to use Spring Integration in my Boot application.
My question is what would cause the DelegatingWebMvcConfiguration to be created before the EmbeddedWebApplicationContext can call prepareEmbeddedWebApplicationContext method.
