Question

我想自己控制hibernate事務，所以我可以在任何時候回滾。我調用一個線程來做生意，但沒有等待它完成工作並更新數據庫。此更新僅在方法結束時可用，但我想在每個for循環中提交更改，因此我需要控制hibernate事務。

我的示例代碼如下：

for(BaseFileprocess fileProcess : unprocessedFiles) { 
      BaseFileprocessfunctype functionType = fileProcessFunctionTypeService.findBySerno(fileProcess.getFunctioncodeserno()); 
      if(functionType != null) { 
       taskExecutor.execute(new ServiceCallThread(functionType.getFunctionname(), fileProcess.getSerno(), fileProcess.getFilename())); 
       fileProcess.setStatu("1"); 
       fileProcessService.update(fileProcess);//I need commit here 
      } 
      else { 
       System.out.println("There is no defined Function Type"); 
      } 
     } 

什麼建議嗎？

調查Spring的transactionTemplate。從文檔：

// single TransactionTemplate shared amongst all methods in this instance 
private final TransactionTemplate transactionTemplate; 

// use constructor-injection to supply the PlatformTransactionManager 
public SimpleService(PlatformTransactionManager transactionManager) { 
    Assert.notNull(transactionManager, "The 'transactionManager' argument must not be null."); 
    this.transactionTemplate = new TransactionTemplate(transactionManager); 
} 

public Object someServiceMethod() { 
    return transactionTemplate.execute(new TransactionCallback() { 

     // the code in this method executes in a transactional context 
     public Object doInTransaction(TransactionStatus status) { 
      updateOperation1(); 
      return resultOfUpdateOperation2(); 
     } 
    }); 
}
