Spring 使用Common TransactionManager管理Hibernate和Activiti

我想为hibernate和activiti使用一个通用事务管理器（

JpaTransactionManager

），但我不能！我已经阅读了所有的网络资源！Hear是一个简单的场景（它甚至不使用hibernate！！）：

在任务中保存变量

在任务#执行中保存变量

完成任务

场景实现（在带有

@Transactional

注释的Springbean方法中）：

很明显：如果

taskService.complete

抛出错误，那么整个事务都应该回滚，所以所有保存的变量都应该回滚，下面的测试用例应该通过：

@Test
@Deployment(resources = "org.activiti.test/CompleteTaskTest.bpmn20.xml")
public void testCompleteTaskWithError() {
    Map<String, Object> processVars = new HashMap<>();
    processVars.put("error", true); // Causes throwing error in ScriptTaskListener
    runtimeService.startProcessInstanceByKey("CompleteTaskTest", processVars);
    Task task = taskService.createTaskQuery().taskName("Task 1").singleResult();

    CompleteTaskRequest req = new CompleteTaskRequest();
    req.setTaskId(task.getId());
    req.setActionDisplayUrl("/actions/1234");
    req.setActionSummaryUrl("/actions/1234/summary");
    try {
        taskManager.completeTask(req);
        fail("An error expected!");
    } catch(Exception e) {
    }

    // Check variables rollback
    assertNull(taskService.getVariableLocal(task.getId(),"actionSummaryUrl"));
    assertNull(taskService.getVariableLocal(task.getId(),"actionDisplayUrl"));
    assertNull(runtimeService.getVariableLocal(task.getExecutionId(), "prevTaskId"));
}

版本：

• Activiti版本：5.22.0
• DB:h2（也在生产中与Oracle一起测试）

我的配置有什么问题

附言

• 测试项目已上载
• 我刚才也提过这个问题

更新：：

---

通过使用

org.springframework.jdbc.datasource.DataSourceTransactionManager

而不是

org.springframework.orm.jpa.JpaTransactionManager

测试用例通过。但现在我无法持久化JPA实体。

通过解决MyBatis（JDBC）和Hibernate（JPA）之间的冲突，问题得到了解决：

jpaVendorAdapter

属性应添加到

entityManagerFactory

bean：

<property name="jpaVendorAdapter">
    <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
</property>
