Question

我在使用mybatis的CMT Spring事务时遇到问题，我有一个使用2个MapperFactoryBean来插入记录的类。

插入获取FOREIGN KEY约束异常的记录时;它似乎都在不同的会话中运行，第二个找不到新插入的ID。

在第二个记录的外键中传递null;抛出没有异常，但也没有提交事务。

如果抛出任何异常，则回滚正常工作。

这是我的配置

    <tx:jta-transaction-manager />

    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">        
    <property name="url" value="${database.url}"/>
    <property name="driverClassName" value="${database.driverClassName}"/>
    <property name="username" value="${database.username}"/>
    <property name="password" value="${database.password}"/>   
    <property name="defaultAutoCommit" value="false" />
    </bean>

    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource"/>
    <property name="nestedTransactionAllowed" value="true" />
    <property name="validateExistingTransaction" value="true" />
    </bean>

    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />            
    <property name="configLocation" value="classpath:dataAccess-config.xml"/>  
    </bean>

    <bean id="taskRecordMapper" class="org.mybatis.spring.MapperFactoryBean">       
    <property name="sqlSessionFactory" ref="sqlSessionFactory" /> 
    <property name="mapperInterface" value="TaskRecordMapper"/>
    </bean>

    <bean id="taskTagRecordMapper" class="org.mybatis.spring.MapperFactoryBean">       
    <property name="sqlSessionFactory" ref="sqlSessionFactory" />
    <property name="mapperInterface" value="TaskTagRecordMapper"/>
    </bean>

代码段

    @Transactional(propagation= Propagation.REQUIRED)
    public boolean assignTask(Object source, TaskType taskType, String description,
                                long assignedTo, long createdBy, long escalationId,
                                boolean isAssignedToGroup, long parentTaskId,
                                Date deadline, TaskPriority taskPriority) throws Exception
    {

    EntityType entityType = TaskUtil.getEntityType(source);
    long entityId = TaskUtil.getIdFromObject(source);

    TaskRecord newTask = new TaskRecord();

    newTask.setAssignedTo((isAssignedToGroup) ? null : assignedTo);
    newTask.setCategory(entityType.toString());
    newTask.setCreatedBy(createdBy); 
    newTask.setCreatedOn(new Date());
    newTask.setDeadline(deadline);
    newTask.setDescription(description);
    newTask.setEntityId(entityId);
    newTask.setEscalationId(escalationId); 
    newTask.setIsAssignedToGroup(isAssignedToGroup);
    newTask.setIsDeleted(false);
    newTask.setModifiedBy(null);
    newTask.setModifiedOn(null);
    newTask.setOwner(createdBy); 
    newTask.setParentId((parentTaskId == 0) ? null : parentTaskId);
    newTask.setPriority(taskPriority.toString());
    newTask.setReferenceNo(null);
    newTask.setResult(null);
    newTask.setStatus(TaskStatus.InProgress.toString());
    newTask.setType(taskType.toString());

    boolean rValue = taskRecordMapper.insert(newTask) > 0;


    if(rValue && isAssignedToGroup)
    {   
        TaskTagRecord tag = new TaskTagRecord();

        tag.setTaskId(newTask.getId());
        tag.setName("RoleId");
        tag.setValue(String.valueOf(assignedTo));

        rValue = taskTagRecordMapper.insert(tag) > 0;
    }


    return rValue;
    }

感谢您的期待

Answer 1

从DEBUG日志中，它似乎从未开始过tx。我认为问题是默认情况下未启用@Transactional。您需要将<tx:annotation-driven transaction-manager="transactionManager" />添加到Spring xml文件中。

Answer 2

不确定这是否会解决问题，但确实有问题：

<tx:jta-transaction-manager/>

这意味着您正在使用JTA，就像在对应用程序服务器的委托事务处理中一样。你也有

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
<property name="nestedTransactionAllowed" value="true" />
<property name="validateExistingTransaction" value="true" />
</bean>

这意味着您正在使用Spring事务处理。我无法在任何地方看到这个bean被明确引用，但这可能会导致一些问题。你想走哪条路，委托给appserver（你是在真正的appserver上运行还是使用Tomcat / Jetty？），还是让Spring处理这些事务？如果是后者，删除指令到JTA，另一个，删除transactionManager定义（或将类更改为JTA事务管理器）。
