I am working on a prototype for using Spring Boot in our project. We have a JBoss server in production and I was thinking of running integration tests against Undertow embedded server using an embedded transaction manager like Atomikos, because a persistence.xml exists that I have to reuse. My test app context file has the following lines:
#RunWith(SpringJUnit4ClassRunner.class)
#SpringApplicationConfiguration(classes = Application.class)
#WebAppConfiguration
#EnableAutoConfiguration
#IntegrationTest("server.port:0")
#ActiveProfiles("test")
public abstract class TestApplicationContext {
...
}
I have also added a custom test configuration as:
#Configuration
public class TestConfiguration {
#Value("${spring.jpa.hibernate.dialect}")
private String dialectClassName;
#Value("${spring.jpa.hibernate.transaction.manager_lookup_class}")
private String transactionManagerClass;
#Bean
public EmbeddedServletContainerFactory servletContainer() {
return new UndertowEmbeddedServletContainerFactory(9000); // Don't know if this can be avoided using some properties
}
#Bean
#ConfigurationProperties(prefix = DataSourceProperties.PREFIX)
public DataSource dataSource() throws Exception {
return DataSourceBuilder.create().build();
}
#Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(EntityManagerFactoryBuilder builder,
DataSource dataSource) {
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean =
builder.dataSource(dataSource).persistenceUnit("main").build();
Properties additionalProperties = new Properties();
additionalProperties.put("hibernate.dialect", dialectClassName);
additionalProperties.put("hibernate.transaction.manager_lookup_class", transactionManagerClass);
entityManagerFactoryBean.setJpaProperties(additionalProperties);
return entityManagerFactoryBean;
}
#Bean
public PlatformTransactionManager transactionManager() {
// this should not be needed if I have included Atomikos but it seems to pick
// JPA Transaction manager still and fails with the famous NullPointerException at
// CMTTransaction class - because it cannot find a JTA environment
// return new JtaTransactionManager(userTransaction, transactionManager);
}
}
My gradle include for Atomikos is:
testCompile('org.springframework.boot:spring-boot-starter-jta-atomikos')
I am using Spring Boot 1.2.0-RC2.
CAn someone point out what I am doing wrong or how to solve this?
Thanks,

I'm trying to write an application that accesses data from two sources. I'm using Spring Boot 2.3.2. I've looked at several sources for info about how to configure the app: the Spring documentation talks about setting up multiple datasources, but does not explain how to link up JPA repositories. This Baeldung article goes a lot further, but I'm looking to take advantage of autoconfiguration in Spring.
So far, I've created a separate package, added a config class (along with model and repositories), and included this package in scanBasePackages so that it's picked up. Since I'll have more than one datasource, I've added this to my #SpringBootApplication:
#Bean
#Primary
public DataSourceProperties dataSourceProperties() {
return new DataSourceProperties();
}
This successfully loads up my Spring app using the standard spring config values. The two databases are on different servers, but should share characteristics (other than url and credentials).
So, my auxiliary configuration file looks like this
#Configuration
#EnableAutoConfiguration
#EnableTransactionManagement
#EnableJpaRepositories(
entityManagerFactoryRef = "orgEntityManagerFactory",
transactionManagerRef = "orgTransactionManager",
basePackages = {
"pacage2.repositories"
}
)
public class DataSourceConfiguration {
// added because of this answer: https://stackoverflow.com/a/51305724/167889
#Bean
public EntityManagerFactoryBuilder entityManagerFactoryBuilder() {
return new EntityManagerFactoryBuilder(new HibernateJpaVendorAdapter(), new HashMap<>(), null);
}
#Bean
#ConfigurationProperties(prefix = "external.datasource")
public DataSourceProperties orgDataSourceProperties() {
return new DataSourceProperties();
}
#Bean
public HikariDataSource orgDataSource(#Qualifier("orgDataSourceProperties") DataSourceProperties properties) {
return properties.initializeDataSourceBuilder().type(HikariDataSource.class)
.build();
}
#Bean
public LocalContainerEntityManagerFactoryBean orgEntityManagerFactory(EntityManagerFactoryBuilder builder,
#Qualifier("orgDataSource") DataSource dataSource) {
return builder
.dataSource(dataSource)
.packages("package2.model")
.build();
}
#Bean
public PlatformTransactionManager orgTransactionManager(
#Qualifier("orgEntityManagerFactory") EntityManagerFactory entityManagerFactory
) {
return new JpaTransactionManager(entityManagerFactory);
}
}
Now, the error I'm getting right now is Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set. However, I have that value in my config and it's applied by the Spring auto config. I believe it needs to be set in the EntityManagerFactoryBuilder and by creating my own, the autoconfig isn't getting applied.
How can I have my cake and eat it too? I'd like to leverage as much of the robust autoconfiguration that Spring provides to setup datasources and wire them to the appropriate repositories. Effectively, all that I want to change is the url and credentials, and I can separate the entities and repositories into a completely separate package for easy scanning.
Confident this hasn't been asked but reading through the Spring docs and testing utilities I found this annotation and thought I'd start using it. Reading through the fine print I read:
Regular #Component beans will not be loaded into the ApplicationContext.
That sounded good and I even liked the idea of using H2 except from what I found the entity I wanted to use had catalog and schema modifiers to it and the default H2 I couldn't figure out how to support that. I made an H2 datasource for the test branch and use that and override the replace. I wound up with
#RunWith(SpringRunner.class)
#ContextConfiguration(classes=ABCH2Congfiguration.class)
#DataJpaTest
#AutoConfigureTestDatabase(replace= AutoConfigureTestDatabase.Replace.NONE)
public class StatusRepositoryTest {
}
However my tests fails fro Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type.
which leads to:
Error creating bean with name 'customerServiceImpl': Unsatisfied dependency.
However the customerServiceImpl is this bean:
#Component
public class CustomerServiceImpl implements CustomerService {
}
That says #Component. The fine print for DataJpaTest says it doesn't load #Components. Why is it doing that and thus failing the test?
As Kyle and Eugene asked below here's the rest:
package com.xxx.abc.triage;
#Component
public interface CustomerService {
}
Configuration
#ComponentScan("com.xxx.abc")
#EnableJpaRepositories("com.xxx.abc")
//#Profile("h2")
public class ABMH2Congfiguration {
#Primary
#Bean(name = "h2source")
public DataSource dataSource() {
EmbeddedDatabase build = new EmbeddedDatabaseBuilder().setType(EmbeddedDatabaseType.H2).setName("ABC").addScript("init.sql").build();
return build;
}
#Bean
public JpaVendorAdapter jpaVendorAdapter() {
HibernateJpaVendorAdapter bean = new HibernateJpaVendorAdapter();
bean.setDatabase(Database.H2);
bean.setShowSql(true);
bean.setGenerateDdl(true);
return bean;
}
#Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(
DataSource dataSource, JpaVendorAdapter jpaVendorAdapter) {
LocalContainerEntityManagerFactoryBean bean = new LocalContainerEntityManagerFactoryBean();
bean.setDataSource(dataSource);
bean.setJpaVendorAdapter(jpaVendorAdapter);
bean.setPackagesToScan("com.xxx.abc");
return bean;
}
#Bean
public JpaTransactionManager transactionManager(EntityManagerFactory emf) {
return new JpaTransactionManager(emf);
}
}
And just to clarify the question, why is #Component being loaded into the context within a #DataJpaTest?
#ComponentScan automatically inject all found #Component and #Service into context. You could override it by separate #Bean:
#Bean
CustomerService customerService{
return null;
}
Or remove #Component annotation from CustomerService and CustomerServiceImpl, but you should add #Bean at your production #Configuration
#DataJpaTest does not load #Component, #Service... by default, only #Repository and internal things needed to configure Spring data JPA.
In your test, you can load any #Configuration you need, and in your case, you load #ABMH2Congfiguration which performs a #ComponentScan that's why Spring try to load your CustomerService.
You should only scanning the #Repository in this configuration class, and scan others #Component, #Service... in another #Configuration like DomainConfiguration. It's always a good practice to separate different types of configurations.
I have developed two webservices using Spring Boot framework and I have them in the same project. Each webservice use a different DB, say ws1 uses Oracle1 and ws2 uses Oracle2. I have defined a DataBaseConfig with the beans definition but when I run the app, always works one webservice ( and it's always the same ).
DataBaseConfig
#Configuration
public class DataBaseConfig {
#Bean(name = "ora1")
#ConfigurationProperties(prefix="spring.datasource")
public DataSource mysqlDataSource() {
return DataSourceBuilder.create().build();}
#Bean(name = "ora2")
#ConfigurationProperties(prefix="spring.secondDatasource")
public DataSource sqliteDataSource() {
return DataSourceBuilder.create().build();}
#Bean(name = "clients")
#Autowired
#ConfigurationProperties(prefix = "spring.datasource")
#Qualifier("datasource")
public JdbcTemplate slaveJdbcTemplate(DataSource datasource) {
return new JdbcTemplate(datasource); }
#Bean(name = "places")
#Autowired
#Primary
#ConfigurationProperties(prefix = "spring.secondDatasource")
#Qualifier("secondDatasource")
public JdbcTemplate masterJdbcTemplate(DataSource secondDatasource) {
return new JdbcTemplate(secondDatasource);}
}
I have the services definition with the sql statements and the definition
#Service
public class ClientsService {
#Autowired
#Qualifier("clients")
private JdbcTemplate jdbcTemplate;
and the other service
#Service
public class PlacesService {
#Autowired
#Qualifier("places")
private JdbcTemplate jdbcTemplate;
Then in each controller I have de mapping #RequestMapping. When I run the app I have no connection-related errors and if I separate the webservices in 2 projects, each works fine.
You have a few things going wrong here, including some unnecessary annotations. See below, note the location of #Qualifier and the qualifier name:
#Bean(name = "clients")
public JdbcTemplate slaveJdbcTemplate(#Qualifier("ora1") DataSource datasource) {
return new JdbcTemplate(datasource);
}
#Bean(name = "places")
#Primary
public JdbcTemplate masterJdbcTemplate(#Qualifier("ora2") DataSource secondDatasource) {
return new JdbcTemplate(secondDatasource);
}
Instead of resolving by bean name, which is a bad idea IMO because it's not typesafe, why don't you use constructor injection and create the services in the configuration class (ditch #Service annotation). Create the DataSource and JdbcTemplate beans as usual, don't give them any names (the default is the method name), and also create new PlacesService(placesJdbcTemplate()). The result is a lot simpler code.
This is assuming you want both databases active at runtime. If not, use #Profile.
I'm trying to using two database connections w/in a Spring Boot (v1.2.3) application as described in the docs (http://docs.spring.io/spring-boot/docs/1.2.3.RELEASE/reference/htmlsingle/#howto-two-datasources.
Problem seems to be that the secondary datasource is getting constructed with the properties for the primary datasource.
Can someone point out what I'm missing here?
#SpringBootApplication
class Application {
#Bean
#ConfigurationProperties(prefix="spring.datasource.secondary")
public DataSource secondaryDataSource() {
return DataSourceBuilder.create().build();
}
#Bean
public JdbcTemplate secondaryJdbcTemplate(DataSource secondaryDataSource) {
return new JdbcTemplate(secondaryDataSource)
}
#Bean
#Primary
#ConfigurationProperties(prefix="spring.datasource.primary")
public DataSource primaryDataSource() {
return DataSourceBuilder.create().build();
}
#Bean(name = "primaryJdbcTemplate")
public JdbcTemplate jdbcTemplate(DataSource primaryDataSource) {
return new JdbcTemplate(primaryDataSource)
}
static void main(String[] args) {
SpringApplication.run Application, args
}
}
application.properties:
spring.datasource.primary.url=jdbc:oracle:thin:#example.com:1521:DB1
spring.datasource.primary.username=user1
spring.datasource.primary.password=
spring.datasource.primary.driverClassName=oracle.jdbc.OracleDriver
spring.datasource.secondary.url=jdbc:oracle:thin:#example.com:1521:DB2
spring.datasource.secondary.username=user2
spring.datasource.secondary.password=
spring.datasource.secondary.driverClassName=oracle.jdbc.OracleDriver
Both JdbcTemplate beans will be getting created with the primary DataSource. You can use #Qualifier to have the secondary DataSource injected into the secondary JdbcTemplate. Alternatively, you could call the DataSource methods directly when creating the JdbcTemplate beans.
I am running HSQL DB as a Im memory using run manger Swing.I have to connect the HSQLDB server from Spring JPA repository using annotations.
My repository class.
#RepositoryRestResource
public interface Vehicle extends JpaRepository<Vehicle , BigInteger>{
public List<Vehicle > findAll(Sort sort);
}
service Method:
#Service
public class LocationService {
#Autowired
VehicletRepository vehicleRepository = null;
/**
* This method is to get all the locations from the repository
*/
public List<Vehicle> getVehicless() {
Order order = new Order(Direction.ASC,"vehicleCode");
Sort sort = new Sort(order);
List<Airport> airports = vehicletRepository .findAll(sort);
System.out.println("inside service");
return vehicles;
}
}
Anyone help to achieve Spring JPA conenction with HSQL DB using annotations.
I assume you dont use Spring boot:
you need #Configuration class -(it basically is new way to configure spring applications in java ) with #EnableJpaRepositories which turn it spring data jpa/ spring data rest for you. You will also have to specify your entity manager, transaction manager and data source beans. Example below:
#Configuration
#EnableJpaRepositories("your.package.with.repositories")
public class DBConfig{
#Bean
public JpaTransactionManager transactionManager() {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(entityManagerFactory().getObject());
return transactionManager;
}
#Bean
public DataSource dataSource() {
BasicDataSource dataSource = new BasicDataSource();
DBConfigurationCommon.configureDB(dataSource, your_jdbc_url_here, db_username_here, db_password_here);
return dataSource;
}
#Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
entityManagerFactoryBean.setDataSource(dataSource());
entityManagerFactoryBean.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
//you may need to define new Properties(); here with hibernate dialect and add it to entity manager factory
entityManagerFactoryBean.setPackagesToScan("your_package_with_domain_classes_here");
return entityManagerFactoryBean;
}
}
