No bean named 'transactionManager' is defined

Question

I have configured two persistent units with the entity managers set up as show below:

<bean id="liveEntityManagerFactory" 
          class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
          p:dataSource-ref="LiveDataSource">          

          <property name="persistenceUnitName" value="LivePersistenceUnit" />
    </bean>

    <bean id="archiveEntityManagerFactory" 
          class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
          p:dataSource-ref="ArchiveDataSource">          

          <property name="persistenceUnitName" value="ArchivePersistenceUnit" />
    </bean>

I then configured the transaction managers as

 <bean id="LiveTransactionManager"
          class="org.springframework.orm.jpa.JpaTransactionManager"
          p:entityManagerFactory-ref="liveEntityManagerFactory"/>

    <bean id="ArchiveTransactionManager"
          class="org.springframework.orm.jpa.JpaTransactionManager"
          p:entityManagerFactory-ref="archiveEntityManagerFactory"/>  

I originally had just one configured and it was called "transactionManager". Addint an additional persistent unit seems to generate an error. One thing i dont understand, if i configured two persistent units (each for a separate database) do i also need to configure an individual entity manager and a transaction manager for each datasource?

The error that i get is shown below: (I have search all file and i cant find anywhere where there is a reference for "transactionManager")

I am using Spring with Jpa/Hibernate.

Thanks

You should use only one TransactionManager, and its bean should be named "transactionManager". – Retardant

The transaction manager has to have a reference to the EntityManagerFactoryBean as shown above. How would i configure it if i have two EntityManagerFactoryBean? (Each for a separate datasource) – Tooth

JPATransactionManager works if you are using only one EntityManager. If using more than one, you need consistency between all your datasources, so you need to resort to org.springframework.transaction.jta.JtaTransactionManager. Are you familiar with JTA? – Retardant

Answer 1

The default value for the transaction-manager attribute is transaction-manager. In your case, you should specify which transaction manager you want to use per method or service like this:

@Service
@Transactional(value="LiveTransactionManager") 
class someClass...

or

@Transactional(value="ArchiveTransactionManager") 
public void someMethod

Safety

This will not work on the service class itself. It must be per method, or else you will get the same exception. However, per the documentation: The default <tx:annotation-driven> target bean name transactionManager will still be used if no specifically qualified PlatformTransactionManager bean is found. – Platto

Where should I define transactionManager in spring boot? – Culicid

Answer 2

Actually, there is a way to use named TransactionManager with Spring Data JPA. This works for me:

<bean id="myTransactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="myEntityManagerFactory" />
</bean>
<tx:annotation-driven transaction-manager="myTransactionManager"/>

<jpa:repositories base-package="com.xxx.yyy" entity-manager-factory-ref="myEntityManagerFactory" transaction-manager-ref="myTransactionManager">
</jpa:repositories>

Answer 3

I use java configuration and specifying the transactionManagerRef was solution for me:

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
    entityManagerFactoryRef = "myCustomEntityManagerFactory",
    basePackages = {"ua.demitt.other.path.to.repos"},
    transactionManagerRef = "myCustomTransactionManager" )

Answer 4

In your @Configuration file, if this is your dataSource:

@Bean(name = "dataSource")
public DataSource getDataSource() {
    return DataSourceBuilder
            .create()
            .username(username)
            .password(password)
            .url(url)
            .build();
}

this would be your transaction manager bean:

@Bean(name = "DataSourceTransactionManager")
public DataSourceTransactionManager getDataSourceTransactionManager() {
    return new DataSourceTransactionManager(getDataSource());
}

Then annotate the service method you would like to be transactional:

@Transactional(transactionManager = "DataSourceTransactionManager", timeout = 60, rollbackFor = { Exception.class})
