Spring中异常时的事务回滚

Question

@Transactional(rollbackFor = Exception.class)
public void createGroupStudent(Student A,Student B,String nameGroup){
    try{
        //create Group
        createGroup(nameGroup);
        //createMember
        createMember(A,B);
    }catch(Exception e){
        logger.error(e.getMessage());
    }
}

@Transactional(rollbackFor = Exception.class)
public void createGroup(String nameGroup){
    try{
        repoGroup.save(nameGroup);
    }catch(Exception e){
        logger.error(e.getMessage());
    }
}

@Transactional(rollbackFor = Exception.class)
public void createMember(Student A,Student B){
    try{
        // function will throw a kind of Exception involve to " error constraint sql oracle " . 
        //It's my intended
        repoMember.save(A,B);
    }catch(Exception e){
        logger.error(e.getMessage());
    }
}

非常感谢

如果您正在使用hibernate，请考虑以下场景。

当Repomember.save(A，B)；执行时，hibernate会话还没有刷新会话（即执行save sql)util createMember（）完成。当hibernate实际刷新并执行save sql时，就会发生此错误。这就是为什么您可能无法捕捉导致事务回滚的异常。
