rareman opened a new issue #400: 我的Saga事务不能保证完整性
URL: https://github.com/apache/servicecomb-pack/issues/400
 
 
   根据tag:0.3.0用户指南写了个demo
   
   ```
     @SagaStart(timeout=10)
     public boolean transferMoney(String from, String to, int amount) {
       self.transferOut(from, amount);
       self.transferIn(to, amount);
     }
   
     @Compensable(timeout=5, compensationMethod="cancel")
     @Transactional
     public boolean transferOut(String from, int amount) {
       return true;
     }
   
     @Transactional
     public boolean cancel(String from, int amount) {
       return true;
     }
   
     @Compensable(timeout=5, compensationMethod="cancelTransferIn")
     @Transactional
     public void transferIn(String to, int amount) {
       try {
         TimeUnit.SECONDS.sleep(15L);
       } catch (InterruptedException e) {
         throw new RuntimeException(e);
       }
       throw new IllegalArgumentException("transter fail");
     }
   
     public void cancelTransferIn(String to, int amount) {
       throw new IllegalArgumentException("transter cancel fail");
     }
   ```
   
   - 问题1
   
       transferIn抛出异常后本地事务回滚，cancelTransferIn会再撤销
   
   - 问题2
   
       cancel不会执行
