即使在两者之间发生错误，休眠也会自动更新我的实体

Posted 2023-02-26

【中文标题】即使在两者之间发生错误，休眠也会自动更新我的实体

【英文标题】：Hibernate is auto updating my entity, even if error occurred in between

【问题描述】：

我有一个名为“程序”的实体。我正在对这个实体进行一些操作。但我不知道如何或为什么，即使我遇到异常，我的实体也会更新。所以谁能帮我解决这个问题。

控制器

@GetMapping("/testtransaction/tid")
public ApiResponse testTransaction(@PathVariable("tid") String tid)
     return gsService.testTransaction(tid);

服务

@Transactional(propagation = Propagation.REQUIRED, readOnly = false, rollbackFor = Exception.class)
public ApiResponse testTransaction(String tid) 
    ApiResponse apiResponse = new ApiResponse();
    try 
        Optional<Program> existProgram = programRepository.findById(tid);
        if(existProgram.isPresent()) 
            //For testing I am setting random value
            existProgram.get().setProgramName("tid_"+(Math.floor(Math.random() * 90 + 10)));
                
            try 
                int err = 8/0;
            catch(Exception e) 
                throw new EntityNotFoundException(Program.class, "prog cd", tid);
            
                    
            programRepository.save(existProgram.get());
            apiResponse.setData("Success");
        else 
            apiResponse.setError("Program details not found for "+tid);
            apiResponse.setStatusCode(500);
        
    catch(Exception e) 
        apiResponse.setError("Something went wrong while testing.");
        apiResponse.setStatusCode(500);
        return apiResponse;
    
    return apiResponse;

所以如果有人以前遇到过这个问题，请帮我解决这个问题:(

【问题讨论】：

你能不能在你的ide里面显示stack trace

您的代码错误。从来没有例外......至少对于您正在捕获所有内容的事务，事务永远不会看到它并且只会提交。所以基本上你让@Transactional 你没用了。您应该让异常冒泡，以便事务拦截器可以相应地采取行动。

@FaeemazazBhanej 我已经将 IDE 的堆栈跟踪添加为“Spring boot log”

@M.Deinum 我的代码是正确的。问题是，如果我在异常之前使用Entiry data 更改任何内容，那么只有我面临这个问题。否则我的代码工作得很好。注意：如果我在异常之前更新实体，休眠本身会触发更新查询。

去掉@Transactional里面的try-catch，使用全局异常处理器处理异常

【参考方案1】：

通过在 catch 或 finally 或函数末尾添加以下代码行，休眠回滚整个事务。

TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
