Question

Hibernate在我的一个测试方法中抛出javax.persistence.TransactionRequiredException。但是，根据日志，有一个正在进行的事务（由Spring创建）。有没有人知道我可能会缺少什么？

查看日志：

INFO  org.springframework.test.context.transaction.TransactionalTestExecutionListener - Began transaction (1) for test context [DefaultTestContext@506dd108 testClass = FooTest, testInstance = com.example.FooTest@59b68d78, testMethod = test@FooTest, testException = [null], mergedContextConfiguration = [MergedContextConfiguration@6001ef4b testClass = FooTest, locations = '{classpath:/appContext.xml}', classes = '{}', contextInitializerClasses = '[]', activeProfiles = '{}', contextLoader = 'org.springframework.test.context.support.DelegatingSmartContextLoader', parent = [null]]]; transaction manager [org.springframework.jdbc.datasource.DataSourceTransactionManager@1f05562b]; rollback [true]
INFO  com.example.FooTest - Test started.
INFO  org.springframework.test.context.transaction.TransactionalTestExecutionListener - Rolled back transaction after test execution for test context [DefaultTestContext@506dd108 testClass = FooTest, testInstance = com.example.FooTest@59b68d78, testMethod = test@FooTest, testException = javax.persistence.TransactionRequiredException: Executing an update/delete query, mergedContextConfiguration = [MergedContextConfiguration@6001ef4b testClass = FooTest, locations = '{classpath:/appContext.xml}', classes = '{}', contextInitializerClasses = '[]', activeProfiles = '{}', contextLoader = 'org.springframework.test.context.support.DelegatingSmartContextLoader', parent = [null]]]

我的测试课程是：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/appContext.xml")
@Transactional
public class FooTest {

    private static final Logger logger = LoggerFactory.getLogger(FooTest.class);

    @PersistenceContext
    private EntityManager em;

    @Test
    public void test() {
        logger.info("Test started.");
        em.createQuery("delete from Foo").executeUpdate();
        logger.info("Test finished.");
    }

}

我的appContext.xml是：

<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:tx="http://www.springframework.org/schema/tx"
  xmlns:jdbc="http://www.springframework.org/schema/jdbc"
  xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans.xsd
           http://www.springframework.org/schema/tx
           http://www.springframework.org/schema/tx/spring-tx.xsd
           http://www.springframework.org/schema/jdbc
           http://www.springframework.org/schema/jdbc/spring-jdbc.xsd">

  <bean id="embeddedEmf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="embeddedDataSource"/>
    <property name="persistenceUnitName" value="Foo" />
  </bean>

  <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="embeddedDataSource"/>
  </bean>

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

  <jdbc:embedded-database id="embeddedDataSource">
    <jdbc:script location="classpath:schema.sql" encoding="UTF-8"/>
    <jdbc:script location="classpath:test-data.sql" encoding="UTF-8"/>
  </jdbc:embedded-database>

</beans>

我的META-INF / persistence.xml非常简单：

<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
    version="2.0">
  <persistence-unit name="Foo">

    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>

    <class>com.example.Foo</class>

  </persistence-unit>
</persistence>

最后，堆栈跟踪（已过滤）：

Answer 1

我同意你应该使用JpaTransactionManager。我还认为你需要标记方法事务：

@Transactional
public void test() {

您可以通过硬编码事务开始并在测试中提交来调试它。它看起来像指向em.createQuery的异常....（因此，如果你想进一步诊断，那么硬编码那里的事务）。

希望有所帮助：）

Answer 2

我使用的是错误的交易管理器。解决方案是取代：

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
  <property name="dataSource" ref="embeddedDataSource"/>
</bean>

通过

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

非常感谢M. Deinum的评论。如果他把它作为答案发布，我会接受它。
