I'm following the Accessing Data with JPA guide and having an issues executing the CommandLineRunner Bean. The problem occurs when manually configuring my database component class. Basically, it works when I have the configuration as below and fails to write when the commented block is included.
Edit - With setShowSql enabled on the JpaVendorAdaptor, I can see select statements being by hibernate attempted, but no attempts at inserts. There are no errors on calling the repository to save, and the ID's are staying at 0 when checked after save.
I don't know if something is configured improperly or if I'm just completely missing a bean or something else.

Im new to spring framework and I Want to migrate data from One DB to another using Spring boot n Batch
Im trying to read from an Mysql db with an item reader and write it to an Oracle db using an item writer of the same job.
Im able to read the data from the Mysql db but unable to write it to Oracle Db as the writer is trying it write it in Mysql Db itself.
Im not sure why the connection is not switching to Oracle db.
Please help me over here what im doing wrong.

I have two spring transaction managers.
txManager1 - ChainedKafkaTransactionManager (KafkaTransactionManager,JpaTransactionManager) configured with datasource DB1
txManager2 - JpaTransactionManager configured with datasource DB2
The problem is that I perform some operation using txManager2 but somehow txManager1 is being used instead of txManager2 and the data is getting committed to DB1 instead of DB2.
#Autowired
#Qualifier("common-tx")
private PlatformTransactionManager txManager2 ;
#KafkaListener(topics = "${kafka.topic.name}", groupId = "group-1", containerFactory = "customKafkaListenerContainerFactory")
public void topicListener(String message, Acknowledgment ack)
throws InterruptedException, ClassNotFoundException, IOException {
DefaultTransactionDefinition def = new DefaultTransactionDefinition();
def.setName(domainEvent.getEventId());
def.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRES_NEW);
TransactionStatus commonStatus = txManager2 .getTransaction(def);
someService.doSomething();
txManager2 .commit(commonStatus);
ack.acknowledge();
}
In doSomething() I am just persisting an entity, upon debugging it is found that while saving the entity via Spring data repository, the transaction manager
determined in invokeWithinTransaction() of org.springframework.transaction.interceptor.TransactionAspectSupport is wrong, i.e. txManager1 is selected instead of txManager2, is it a configuration issue or am I missing something?

There is an custom repository interface that implements JPARepository.
I have autowired the custom repository in controller and tried to call findAll().But the method returns 0 although there are 3 records in DB.
I am using spring web for rest service calls.
Entity class is created with #Entity and #Table annotations.It has an embedded key which is annotated using #EmbeddedId annotation.
#Repository
public interface EntityRepository extends JpaRepository<EntityTable, Long> {
#SuppressWarnings("unchecked") EntityTable save(EntityTable entityTable);
}
Entity table is the name of my table mapped with db table.
I use Spring Data JPA and use multiple database, so I must configure it myself instead of using #HibernateJpaAutoConfiguration.
public class TesterDbConfig {
#Autowired(required = false)
private PersistenceUnitManager persistenceUnitManager;
#Bean
public JpaProperties testerJpaProperties() {
JpaProperties jpaProperties = new JpaProperties();
return jpaProperties;
}
#Bean
#Primary
#ConfigurationProperties(prefix = "datasource.primary")
public DataSource testerDataSource() {
return (DataSource) DataSourceBuilder.create().type(DataSource.class).build();
}
#Bean
public LocalContainerEntityManagerFactoryBean testerEntityManager(
JpaProperties testerJpaProperties) {
EntityManagerFactoryBuilder builder = createEntityManagerFactoryBuilder(testerJpaProperties);
return builder.dataSource(testerDataSource()).packages(Cabang.class).persistenceUnit("primary")
.build();
}
#Bean
public JpaTransactionManager testerTransactionManager(EntityManagerFactory testerEntityManager) {
return new JpaTransactionManager(testerEntityManager);
}
private EntityManagerFactoryBuilder createEntityManagerFactoryBuilder(
JpaProperties testerJpaProperties) {
JpaVendorAdapter jpaVendorAdapter = createJpaVendorAdapter(testerJpaProperties);
return new EntityManagerFactoryBuilder(jpaVendorAdapter, testerJpaProperties,
this.persistenceUnitManager);
}
private JpaVendorAdapter createJpaVendorAdapter(JpaProperties testerJpaProperties) {
AbstractJpaVendorAdapter adapter = new HibernateJpaVendorAdapter();
adapter.setShowSql(testerJpaProperties.isShowSql());
adapter.setDatabase(testerJpaProperties.getDatabase());
adapter.setDatabasePlatform(testerJpaProperties.getDatabasePlatform());
adapter.setGenerateDdl(testerJpaProperties.isGenerateDdl());
return adapter;
}
}
With this, every time I create a model, I must use #Column in every variable because in my database, I use snake case, but in model class, I use camel case.
How can I set the Hibernate naming strategy?
You can set it via JpaProperties, which you already use in your configuration:
#Bean
public JpaProperties testerJpaProperties() {
JpaProperties jpaProperties = new JpaProperties();
JpaProperties.Hibernate hibernate = new JpaProperties.Hibernate();
hibernate.setNamingStrategy(SpringNamingStrategy.class);
jpaProperties.setHibernate(hibernate);
return jpaProperties;
}
And add
#Bean
public LocalContainerEntityManagerFactoryBean testerEntityManager(
JpaProperties testerJpaProperties) {
EntityManagerFactoryBuilder builder = createEntityManagerFactoryBuilder(testerJpaProperties);
return builder.dataSource(testerDataSource())
.packages(Cabang.class)
.persistenceUnit("primary")
.properties(Collections.singletonMap("hibernate.ejb.naming_strategy",testerJpaProperties.getHibernate().getNamingStrategy()))
.build();
}
I'm attempting to transactionally interact with my MySQL database through JPA and Spring data.

factory.setJpaProperties(additionalProperties());
factory.setPackagesToScan(new String[] { "com.datarank.megabots.models.entities", "com.datarank.megabots.models.repositories" });
factory.setDataSource(dataSource());

}
#Bean
public DataSource dataSource(){
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName("com.mysql.jdbc.Driver");
dataSource.setUrl("jdbc:mysql://localhost:3306/local_ttaggdb");
dataSource.setUsername( "root" );
dataSource.setPassword( "" );
return dataSource;

properties.setProperty("hibernate.hbm2ddl.auto", "create-drop");
properties.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect");
return properties;
}
//...
}
And here's where I'm attempting to use a transaction:
#Repository
#Scope("prototype")
#Transactional
public class BotWorkQueueRepository {
#Autowired
private BotWorkQueueJPARepository botWorkQueueJPARepository; //this is the jparepository referenced in the #EnableJpaRepositories in config
#PersistenceContext
private EntityManager entityManager;
#Transactional
public synchronized void flagInFlight(final List<BotWorkQueueEntity> botWorkQueueEntities) {
try {
//...set a few properties on entities, then
entityManager.flush(); //Exception thrown here
entityManager.clear();
} catch (Exception e) {
LOGGER.warn("Error making in flight: " + e);
}
}
}
The error I'm getting:
javax.persistence.TransactionRequiredException: No transactional EntityManager available
I've tried most of the solutions for this error posted in SO, with no success.
One thing for starter,
In maven, if you are using the appassembler-maven-plugin, add the following line to your plugin.configuration tag in the POM file.
<extraJvmArguments>-javaagent:"$REPO"/org/aspectj/aspectjweaver/1.8.5/aspectjweaver-1.8.5.jar</extraJvmArguments>
If you are running in an IDE add the following line to your VM arguments.
-javaagent:<PATH TO MAVEN REPO>/org/aspectj/aspectjweaver/1.8.5/aspectjweaver-1.8.5.jar
Where path to maven repo may look something like /User/kenny/.m2/repository/.
$REPO will be auto-resolved in the POM file.
