正确包#xff1a…问题解决sprigboot项目get请求中有下划线的入参参数如first_name希望在项目中将下划线格式转成firstName用JsonProperty注解发现失效问题
1.核查JsonProperty注解对应包是否正确
正确包import com.fasterxml.jackson.annotation.JsonProperty;
如果使用jar正确还是无效往下看
2.在实体类中重写参数的set方法
例子
实体类
package com.iterge.lph_test.entity;import lombok.AccessLevel;
import lombok.Data;
import lombok.experimental.FieldDefaults;/*** Create by LPH 2021/8/3*/
Data
FieldDefaults(level AccessLevel.PRIVATE)
public class UserReq {Long id;String name;String firstName;
}Controller
package com.iterge.lph_test.controller;import com.iterge.lph_test.entity.UserReq;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;/*** author liuph* date 2023/8/10 15:01:30*/RestController
RequestMapping(/test)
Slf4j
public class ParamController {GetMapping(/param/test)public String params(UserReq req){log.info(入参数{},req);return req.toString();}}结果 修改后
实体类
package com.iterge.lph_test.entity;import com.fasterxml.jackson.annotation.JsonProperty;
import lombok.AccessLevel;
import lombok.Data;
import lombok.experimental.FieldDefaults;/*** Create by LiuPH 2021/8/3*/
Data
FieldDefaults(level AccessLevel.PRIVATE)
public class UserReq {Long id;String name;JsonProperty(first_name)String firstName;public void setFirst_name(String name){this.firstName name;}
}运行结果 over
