分析Springboot中嵌套事务失效原因详解

@Transactional(rollbackFor = Exception.class)
public void trance() {
    try {
        trance1();//调用下一个事务方法。
    } catch (Exception e) {
        e.printStackTrace();
    }
        User user = new User();
        ShardingIDConfig shardingIDConfig = new ShardingIDConfig();
        user.setId(shardingIDConfig.generateKey().longValue());
        user.setName("trance");
        user.setSex(0);
        userMapper.create(user);
}
 
@Transactional(propagation = Propagation.REQUIRED)
public void trance1() throws Exception{
    User user = new User();
    ShardingIDConfig shardingIDConfig = new ShardingIDConfig();
    user.setId(shardingIDConfig.generateKey().longValue());
    user.setName("trance1");
    user.setSex(1);
    userMapper.create(user);
    System.out.println(user.getId());
    throw new RuntimeException();
