java - @Transactional 的范围

问题描述

例如，我有一个类似这样的代码

@Transactional(propogation=PROPOGATION.REQUIRED)
public class codeForTest {

  public void doSomethins(){
    User user = userRepository.finduserById(userId);
    updateUserDetails(user);
    updateFewOtherDetails(user);
  }

}

public class DifferentClass{

  @Transactional(propogation=PROPOGATION.REQUIRED)
  updateUserDetails() {
    //UPDATES user object
  }

}

在具有上述逻辑的几个实例中，我得到了以下信息。我在本地机器上没有收到错误。我的问题是 updateUserDetails() 是否会提交事务，并且在执行 updateFewOtherDetails() 时，由于事务已提交，是否会引发异常？我怀疑这是否会造成问题，因为在哪里用 @Transactional 注释它（propogation= PROPOGATION.REQUIRED）

解决方案

一旦它们都标记为 ，这两种方法都将在单个事务的范围内执行@Transactional。

user对象被加载到不同事务的边界或从缓存中获取，在某种情况下.finduserById()使用一个。

确保您也标记了@Transactional第二种.updateFewOtherDetails()方法。

通过传播REQUIRED，直到调用者序列结束，事务才会提交。
