可重现问题的全部代码哦,不然怎么复现

wendal

2楼•3132天前

看上去是 cn.uwf.bean.wf.RoleMenu.hashCode方法, 里面调用了getMenu导致递归了, 改成直接拿属性吧

Longitude (qq_5cfdd686) 3楼•3132天前

可是我就是要用这整个对象。

@qq_5cfdd686 hashCode方法内的避免使用getter,应该就好了

Longitude (qq_5cfdd686) 5楼•3132天前

怎么定义，我没有用Hashcode。。

wendal

整个 RoleMenu 类贴出来, 记得用菜单中的代码块.

```java
@EqualsAndHashCode(doNotUseGetters=true)

加一个注解

@EqualsAndHashCode(doNotUseGetters=true)

@wendal

@EqualsAndHashCode(doNotUseGetters=true)

是什么意思

wendal

11楼•3132天前

@javanan lombok 的一个注解, 看上去有用,但一堆蛋疼问题的东西,哈哈, 曾经在公司项目用过,后来抛弃了, 收益比痛点少.

javanan

@wendal 您既然推荐这么蛋疼的东西给他用，，哈哈哈

wendal

13楼•3132天前

@javanan 我哪里推荐了？@Data是他自己加的，加上我写的只是限制一下行为
