[party benefits] jsonobject to string, leave blank

The same problem ：

Redis Leave an empty field and take it out

JSONObject To String Leave blank fields when typing

take String Type to JSONObject Leave blank fields when typing

reason

Object The type and JSONObject Type to String When type , Empty fields are automatically ignored .

Solution

Use class Entity classes are output as templates , take String Type to entity type
Need to introduce hutool

import cn.hutool.json.JSONUtil;
...


UserInfo userinfo = JSONUtil.toBean(String.valueOf(redisUtil.get(UserToken)),UserInfo.class)

UserInfo.java

import lombok.Data;
// Virtual entity class that outputs user information 
@Data
public class UserInfo {
    
	private String id;
	private String username;
	private String realname;

}

Then through the entity class get and set Just output .
