异常信息： 出现了不可预知的回滚异常，因为事务已经被标志位只能回滚，所以事务回滚了。

Spring事务传播机制汇总如下：

1.  PROPAGATION\_REQUIRED：如果当前没有事务，就新建一个事务，如果已经存在一个事务，就加入到这个事务中。默认策略
2.  PROPAGATION\_SUPPORTS：支持当前事务，如果当前没有事务，就以非事务方式执行。
3.  PROPAGATION\_MANDATORY：使用当前的事务，如果当前没有事务，就抛出异常。
4.  PROPAGATION\_REQUIRES\_NEW：新建事务，如果当前存在事务，把当前事务挂起。
5.  PROPAGATION\_NOT\_SUPPORTED：以非事务方式执行操作，如果当前存在事务，就把当前事务挂起。
6.  PROPAGATION\_NEVER：以非事务方式执行，如果当前存在事务，则抛出异常。
7.  PROPAGATION\_NESTED：如果当前存在事务，则在嵌套事务内执行。如果当前没有事务，则执行与PROPAGATION\_REQUIRED类似的操作。  
    nested 的子异常抛出 如果被catch 外部插入成功  
    nested 的子异常抛出 如果不被catch 外部插入失败  
    nested外面异常抛出 nest内部插入成功 nest也会跟着回滚

spring事务默认的传播行为：  
@Transactional 等于 @Transactional(propagation=Propagation.REQUIRED)

发生异常的场景描述：  
在使用Spring事务时，在一个事务A中又开了一个事务B（即存在嵌套事务），当事务B发生异常时，将异常catch后事务B会进行回滚操作，若此时异常被直接吃掉（即事务A无法得知发生过异常），则事务A会抛出如上异常。

serviceA有事务 @Transactional
     serviceB有事务 @Transactional
     
      serviceA.methodA() 
     {  
           doSomethingA();  
          try {  
                 serviceB.methodB{}; //这里面有异常标记为回滚, doSetRollbackOnly(status);  
              }
               catch {  
                    //捕获异常转到commit时，由于已经标记为要回滚， 回滚并抛出新异常     
                   }         
           doSomethingB();  
      }

**原因：**  
因为methodB的传播属性设置为PROPAGATION\_REQUIRED，PROPAGATION\_REQUIRED的意思是，当前有事务，则使用当前事务，当前无事务则创建事务。由于methodA的传播属性也为PROPAGATION\_REQUIRED，所以methodA会创建一个事务，然后methodB与methodA使用同一个事务，methodB出现异常后，将当前事务标志位回滚，由于在methodA中做了trycatch处理，程序没有终止而是继续往下走，当事务commit时，check状态，发现，需要事务回滚，所以才会出现不可预知的事务异常:因为事务被标志位回滚，所以事务回滚。  
也就是说:methodA与methodB共用一个事务，methodB将事务标志为回滚，methodA中commit这个事务，然后，出现事务已经被标志回滚（methodB标志的）的异常信息。

解决方案  
情况1：methodA与methodB在逻辑上不应该属于同一个事务，那么将methodB的事务传播属性修改为PROPAGATION\_REQUIRES\_NEW，这样，执行methodB时，会创建一个新的事务，不影响methodA中的事务。

情况2：业务A与业务B在业务逻辑上就应该属于同一个事务，那么将methodA中的try catch去掉

情况3：业务A与业务B在业务逻辑上就应该属于同一个事务，但是methodB的失败与否不能影响methodA的事务提交，那么仍然在methodA中try catch methodB,并将methodB设置为PROPAGATION\_NESTED，它的意思是，methodB是一个子事务，有一个savepoint，失败时会回滚到savepoint，不影响methodA，如果成功则A、B一起提交，A与B都是一个事务，只是B是一个子事务。  
情况4：业务A 有无事务无影响 去掉业务A的@Transactional

小结：

1.  深入理解事务传播的各个状态含义，比如PROPAGATION\_REQUIRED、PROPAGATION\_SUPPORTS、PROPAGATION\_MANDATORY、PROPAGATION\_REQUIRES\_NEW等
2.  最初我以为是由于spring配置文件中，methodA的事务设置为ready-only=true(只读事务)的原因，经过查询资料得知，只读事务与事务传播不冲突，是两个机制。只读事务，是一个特殊的事务，该事务内，只能是查询语句，不能含有修改、更新语句，数据库可能对只读事务做优化；传播属性是母方法与子方法之间的关系表达。
3.  注意，同一个类中，事务嵌套以最外层的方法为准，嵌套的事务失效；不同类中嵌套的事务才会生效；
