Question

我已经创建了一个服务的集成测试，该服务在完成后没有回滚事务。我从查看db和我第二次运行测试时得到的错误就知道了这一点。我整个上午一直在谷歌上搜索这个问题，觉得我已经把一切都设置好了。这是一个写入SQLServer 2008的hibernate / jpa应用程序。我不确定在哪里查看。下面的代码段。

@RunWith(SpringJUnit4ClassRunner.class)
@TestExecutionListeners({
        DependencyInjectionTestExecutionListener.class,
        DirtiesContextTestExecutionListener.class,
        TransactionalTestExecutionListener.class })
@TransactionConfiguration(defaultRollback=true)
@Transactional // extend transactional boundary to test class so that automatic rollback works properly
@ContextConfiguration(locations = {
        "file:./src/main/resources/AghostMobile.Service-business.service-context.xml",
        "file:./src/main/resources/AghostMobile.Service-service-context.xml",
        "file:./src/main/resources/AghostMobile.Service-dao-context.xml"})
public class ColorSchemeMigrationServiceIntTest {

    /**
     * The service being tested, injected by Spring
     *
     */
    @Autowired
    ColorSchemeMigrationService service;

    /**
     * The helper services, injected by Spring.
     *
     */
    @Autowired
    protected WebsitecolorpaletteuserdefinedService userPaletteService;
    @Test
    public void testSaveColorPalette() {
        Integer mobileWebsiteId = Integer.valueOf(386);
        Integer custId = Integer.valueOf(15);
        Integer siteId = Integer.valueOf(2);
        String user = "Test";

        Websitecolorpaletteuserdefined palette = service.translateColorScheme(mobileWebsiteId, custId, siteId, user);

        service.saveColorPalette(palette);

        Websitecolorpaletteuserdefined response = userPaletteService.findWebsitecolorpaletteuserdefinedByCustIdAndSiteId(custId, siteId);

        assertNotNull("User palette not found.", response);
        assertEquals("CustId is not the expected value.", custId, response.getCustId());
        assertEquals("SiteId is not the expected value.", siteId, response.getSiteId());
    }

目前，我定义了以下bean：

<!-- ******************************************************************** -->
<!-- Setup the transaction manager -->
<!-- ******************************************************************** -->
    <!-- Using Atomikos Transaction Manager -->
    <bean id="atomikosTransactionManager" class="com.atomikos.icatch.jta.UserTransactionManager" init-method="init"
        destroy-method="close">
        <property name="forceShutdown" value="true" />

        <property name="transactionTimeout" value="60" />
    </bean>

    <bean id="atomikosUserTransaction" class="com.atomikos.icatch.jta.UserTransactionImp" />
    <!-- Configure the Spring framework to use JTA transactions from Atomikos -->
    <bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager">
        <property name="transactionManager" ref="atomikosTransactionManager" />
        <property name="userTransaction" ref="atomikosUserTransaction" />
        <property name="transactionSynchronizationName" value="SYNCHRONIZATION_ON_ACTUAL_TRANSACTION" />
    </bean>
<!-- ******************************************************************** -->

<bean name="hostDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" >
    <property name="driverClassName" value="${My_JDTs_to_AgHost_Host_scheme.connection.driver_class}" />
    <property name="username" value="${My_JDTs_to_AgHost_Host_scheme.connection.username}" />
    <property name="password" value="${My_JDTs_to_AgHost_Host_scheme.connection.password}" />
    <property name="url" value="${My_JDTs_to_AgHost_Host_scheme.connection.url}" />
    <property name="maxIdle" value="${My_JDTs_to_AgHost_Host_scheme.minPoolSize}" />
    <property name="maxActive" value="${My_JDTs_to_AgHost_Host_scheme.maxPoolSize}" />
</bean>

<!-- ******************************************************************** -->
<!-- Setup each persistence unit -->
<!-- ******************************************************************** -->
            <!-- Configure a JPA vendor adapter -->
            <bean id="My_JDTs_to_AgHost_Host_schemeJPAVendorAdapter" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
                <property name="showSql" value="${My_JDTs_to_AgHost_Host_scheme.show_sql}" />
                <property name="generateDdl" value="${My_JDTs_to_AgHost_Host_scheme.generateDdl}" />
                <property name="databasePlatform" value="${My_JDTs_to_AgHost_Host_scheme.dialect}" />
            </bean>
            <!-- EntityManager Factory that brings together the persistence unit, datasource, and JPA Vendor -->
            <bean id="My_JDTs_to_AgHost_Host_scheme" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
                <property name="dataSource" ref="hostDataSource" />
                <property name="persistenceUnitName" value="My_JDTs_to_AgHost_Host_scheme" />
                <property name="jpaVendorAdapter" ref="My_JDTs_to_AgHost_Host_schemeJPAVendorAdapter" />
                    <property name="jpaPropertyMap">
                        <map>
                                    <entry key="hibernate.transaction.manager_lookup_class" value="com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup" />
                                    <!-- <entry key="hibernate.transaction.factory_class" value="org.hibernate.transaction.JTATransactionFactory" /> -->
                                    <entry key="hibernate.connection.release_mode" value="on_close" />
                        </map>
                    </property>
            </bean>

这允许我更新我的数据，但不会回滚我的交易。所以，我使用的是事务管理器org.springframework.jdbc.datasource.DataSourceTransactionManager。我用“安装事务管理器”块替换了三个bean：

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

这使我的测试失败了 IllegalStateException：这个方法需要一个调用线程的事务而且不存在。该例外也说明了：

Possible causes: either you didn't start a transaction,
it rolledback due to timeout, or it was committed already.
ACTIONS: You can try one of the following: 
1. Make sure you started a transaction for the thread.
2. Make sure you didn't terminate it yet.
3. Increase the transaction timeout to avoid automatic rollback of long transactions;
   check [http://www.atomikos.com/Documentation/JtaProperties][1] for how to do this.

我承认还没有阅读该文件，并会在发布这些更新后这样做。我也找到了这个线程，看起来很有希望：persistence-unit, different hibernate.transaction.manager_lookup_class property。您可以在bean My_JDTs_to_AgHost_Host_scheme中看到注释掉的内容。这失败了相当悲惨。但是，也许我没有正确使用它。

我也找到了这个帖子：Spring/JTA/JPA DAO integration test doesn't rollback?。这看起来很有希望，但我不知道如何使用它告诉我的内容。

Answer 1

答案原来在这里找到：Spring/JTA/JPA DAO integration test doesn't rollback?。我将数据源更改为以下内容。

<bean name="hostDataSource" class="com.atomikos.jdbc.nonxa.AtomikosNonXADataSourceBean" destroy-method="close" >
    <property name="driverClassName" value="${My_JDTs_to_AgHost_Host_scheme.connection.driver_class}" />
    <property name="user" value="${My_JDTs_to_AgHost_Host_scheme.connection.username}" />
    <property name="password" value="${My_JDTs_to_AgHost_Host_scheme.connection.password}" />
    <property name="url" value="${My_JDTs_to_AgHost_Host_scheme.connection.url}" />

    <property name="maxPoolSize" value="20" />
    <property name="reapTimeout" value="300" />
    <property name="uniqueResourceName" value="myappDatabase" />
</bean>

Answer 2

在加载的上下文中是否有DataSourceTransactionManager bean？
