上面是我的配置文件，主要是红色的代码， rollback-for="DaoException" 很关键，这里我指定的要回滚的异常是我的自定义异常DaoException，因此在程序中，如果抛出了未被捕获的该异常，则事务回滚，参见下面代码：
[java]
public RPCMessage saveUser(TUmUserDTO entity)span style="color:#ff0000; "> throws DaoException /span> {
log.info("服务层操作：添加从业者 saveUser (TUmUserDTO [" + entity + "])");
try {
if (entity == null) {
throw new ServiceException(
ServiceException.ERRORCODE_PARAM_NULL);
}
如果rollback-for="ServiceException" ，但是程序中catch住了该异常，则事务不回滚，因为异常被生吞了，事务已经被提交了，参见下面代码：
[java]
log.debug("服务层操作：从业者角色编辑完成");
return this.getRPCMessage();
} catch (span style="color:#ff0000; "> ServiceException /span> e){
return this.getRPCMessage(e);
}
如果rollback-for="Exception" ，则属于Exception以及Exception包含的异常都会事务回滚，这里因为DaoException，ServiceException都是继承自Exception，因此也会回滚。
配置中的：expression=" execution(* com.xbzc.phr.service.um.UserManageSrv.*(..))" /> 的作用是，事务回滚时，对哪些类中的方法起作用 。
如果没有配置rollback-for=" " 则默认只回滚未被捕获的运行时异常引起的操作。
