我正在构建一个工作流系统,其中服务层 - WorkflowServiceImpl
处理文档并向用户发送通知。 还有另一种服务DocumentServiceImpl
,它有一个方法post()
方法,它在内部调用WorkflowServiceImpl.process()
方法。Spring @Transactional注释行为
@Service
public class WorkflowServiceImpl implements WorkflowService{
@Transactional(propagation=Propagation.REQUIRES_NEW, noRollbackFor=WorkflowException.class)
public void process(WorkflowDocument document) throws WorkflowException {
Boolean result = process(document);
if(!result){
throw new WorkflowException();
}
}
private Boolean process(WorkflowDocument document){
//some processing on document
updateDocument();
sendNotifications();
}
private void updateDocument(WorkflowDocument document){
//some update operation
}
private void sendNotifications(WorkflowDocument document){
//send notifications - insertion operation
}
}
@Service
public class DocumentServiceImpl implements DocumentService{
@Autowired private WorkflowService workflowService;
@Transactional
public void post(){
//some operations
workflowService.process(document);
//some other operations
}
}
正如你所看到的,我已经打上
DocumentServiceImpl.post() as @Transactional
WorkflowServiceImpl.process() as @Transactional(propagation=Propagation.REQUIRES_NEW, noRollbackFor=WorkflowException.class)
我试图做到这一点:
1. WorkflowServiceImpl.process() method should commit always(update document and send notifications) - whether a WorkflowException is thrown or not
2. DocumentServiceImpl.post() method should rollback, when WorkflowException is thrown
当我尝试使用上述交易结构
1. When WorkflowException is not thrown, the code worked as expected - committed both WorkflowServiceImpl.process() and DocumentServiceImpl.post() methods
2. When WorkflowException is thrown, the request processing is not completed (I can see the request processing symbol in the browser)
我找不到什么代码是错误的。我使用Spring版本3.1.4
对于'private'方法,'@ Transactional'是无用的,即使你将这些方法设置为public,它也不起作用,因为内部方法调用不会通过用于应用AOP的代理。 –
@M。 Deinum我已根据您的建议更正了代码。你能指导我实现这个目标吗? – faizi
