问题描述:
There is a cycle in the hierarchy!
List res = resourceService.findAll();
JSONArray datalist = JSONArray.fromObject(res);//这里报错there is a cycle in the hierarchy
用网上提供的方法不好使
下面是Resource属性
private Integer id;
\x05private String title;
\x05private String description;
\x05private Set roles = new HashSet();
Resource和Role有多对多的关系
Role的属性
private Integer id;
\x05private String roleName;
\x05private Set res = new HashSet();
List res = resourceService.findAll();
JSONArray datalist = JSONArray.fromObject(res);//这里报错there is a cycle in the hierarchy
