Spring批处理,单元测试,JPA事务和Hibernate延迟加载:IllegalTransactionStateException

标签: java hibernate jpa spring-batch transactionmanager

Hy guys,

我想运行一个spring批处理作业然后对结果进行一些测试,但是我需要使用hibernate延迟加载。所以我需要一个打开的事务来保持会话的活跃。

但是我得到了这个异常:IllegalTransactionStateException:找到了预绑定的JDBC连接!

我可以编写方法来直接获取我想要测试的关联对象,但我不想只为测试编写方法并且放弃hibernate的优点。

有办法做到这一点吗?我试图在jobRepositoy中将validateStateTransaction设置为false,但它不起作用(事实上它只适用于内存元数据存储库,如MapJobRepository)。

我正在寻找几天,但没有任何效果。

你能帮帮我吗?感谢

我的代码在这里:

<bean id="jobRepository"
    class="org.springframework.batch.core.repository.support.JobRepositoryFactoryBean">
    <property name="databaseType">
        <value>POSTGRES</value>
    </property>
    <property name="dataSource" ref="databasePool" />
    <property name="transactionManager" ref="transactionManager" />
    <property name="isolationLevelForCreate" value="ISOLATION_DEFAULT" />
    <property name="tablePrefix" value="#{ schema }.BATCH_" />
    <property name="validateTransactionState" value="false" />
</bean>

@Test
@Transactional
public void test() {

    /*
     * ===================RUN JOB======================
     */
    JobParameters jobParameters = new JobParametersBuilder();

    int returnCode = runJob("job_name", jobParameters);
    assertEquals("returnCode must be 0.", 0, returnCode );

    /*
     * ===============END JOB=============================
     */

    /*
     * ===============TEST ON DATA==========================
     */
    ObjectToTest obj = objectDao.findById("1");

    assertNotNull( obj.getSomeCollection().get(1));

    /*
     * =================END TEST==================
     */

}

以下是例外:

org.springframework.transaction.IllegalTransactionStateException: Pre-bound JDBC Connection found! JpaTransactionManager does not support running within DataSourceTransactionManager if told to manage the DataSource itself. It is recommended to use a single JpaTransactionManager for all transactions on a single DataSource, no matter whether JPA or JDBC access.

我尝试将测试部分放在另一个可以使用@Transactional进行分配的方法中,但后来我得到了一个LazyInitializationException ......

编辑:

我使用org.springframework.orm.jpa.JpaTransactionManager实现事务管理器。

这是我的弹簧配置:

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="myEmf" />
</bean> 

<tx:annotation-driven transaction-manager="transactionManager"/>

我已经搜索了手动打开交易的方式,但我还没有找到它

好的,我找到了一个解决方案(最后没有任何帮助)。

要执行此操作,您必须在作业结束后手动打开交易。

你可以这样做:

@Autowired
protected PlatformTransactionManager transactionManager;

@Test
public void test() {

/*
 * ===================RUN JOB======================
 */
JobParameters jobParameters = new JobParametersBuilder();

int returnCode = runJob("job_name", jobParameters);
assertEquals("returnCode must be 0.", 0, returnCode );

/*
 * ===============END JOB=============================
 */

/*
 * ===============TEST ON DATA==========================
 */
(new TransactionTemplate(transactionManager)).execute(new TransactionCallback() {
        @Override
        public Object doInTransaction(TransactionStatus status) {

          ObjectToTest obj = objectDao.findById("1");

          assertNotNull( obj.getSomeCollection().get(1));
 }
});

/*
 * =================END TEST==================
 */
