Question

我已配置了两个长期存在的单位,由下列实体管理人员组成:

<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>

然后,我将交易经理人配置为

 <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?

我得到的错误显示在下面:(我已经搜索了所有文件, 找不到任何“ 交易管理器” 的引用) 。

我和Jpa/Hibertate在用"春天"

谢谢谢谢

Answer 1

交易管理器属性的默认值是交易管理器。在您的情况下, 您应该指定您想要使用哪种交易管理器, 或者像这样的服务 :

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

或

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

Answer 2

实际上,是使用名为“Spring Data JPA”的“交易管理器”的“Spring Data JPA”方法。

<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

我使用 java 配置, 并指定“ 强势” 交易管理Ref < / 强” 是对我而言的解决方案 :

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

Answer 4

在您的@ Configifation 文件中, 如果这是您的数据来源 :

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

这就是你们的交易经理人所享受的享受。

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

然后说明您想要交易的服务方法 :

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