@Transactional事务嵌套调用

两个方法都加了@Transactional，不管是外层方法testInsert1还是内层方法testInsert2出错了，都会回滚

@Transactional(rollbackFor = Exception.class)
    public void testInsert1() {
        Student s = new Student("Yann");
        this.insert(s);
        testInsert2();
    }

    @Transactional(rollbackFor = Exception.class)
    public void testInsert2() {
        Student s = new Student("Yoki");
        this.insert(s);
        int num = 5/0;//抛异常
    }

@Transactional(rollbackFor = Exception.class)
    public void testInsert1() {
        Student s = new Student("Yann");
        this.insert(s);
        testInsert2();
        int num = 5/0;//抛异常，testInsert2插入的数据也会回滚
    }

    @Transactional(rollbackFor = Exception.class)
    public void testInsert2() {
        Student s = new Student("Yoki");
        this.insert(s);
    }
