注解@JSONField和@JsonProperty的简单使用
本注解的使用，需要引入fastjson依赖
<!--添加fastjson依赖-->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
<version>1.2.70</version>
</dependency>
首先对时间格式化
时间格式化后
代码部分
package com.java.test.json.field;
import lombok.Data;
import java.util.Date;
/**

*/
@Data
public class HistoryPasswordDemo {
/**
* id值
*/
private String id;
/**
* 密码
*/
private String pass_word;
/**
* 创建时间
*/
private Date create_time;
/**
* 修改时间

private Date updateTime;
/**

private String create_user;
}

@Controller
@CrossOrigin
@RequestMapping("/historyPassword")
@Slf4j
public class HistoryPasswordController {
/**

*/
@RequestMapping("/getHistoryPasswordList")
@ResponseBody
public HistoryPasswordDemo getHistoryPasswordList(@RequestBody HistoryPasswordDemo historyPasswordDemo) {

}
}
# 格式化全局时间字段 spring.jackson.date-format=yyyy-MM-dd HH:mm:ss # 指定时间区域类型 spring.jackson.time-zone=GMT+8
@JsonProperty使用
package com.java.test.json.field;
import com.fasterxml.jackson.annotation.JsonProperty;
import lombok.Data;
/**

*/
@Data
public class UserDTO {
/**
* 用户名
*/
@JsonProperty("user_name")
private String userName;
/**
* 密码
*/
@JsonProperty("pass_word")
private String password;
}
package com.java.test.json.field;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang.StringUtils;
import org.springframework.web.bind.annotation.*;
import java.util.HashMap;
import java.util.Map;
/**

*/
@RequestMapping("/login")
@RestController
@CrossOrigin
@Slf4j
public class LoginController {
@PostMapping("/login")
public Map<String, Object> login(@RequestBody UserDTO userDTO){
log.info("userDTO:{}",userDTO);
Map<String,Object> result=new HashMap<>();
if (StringUtils.equals("admin",userDTO.getUserName())&&StringUtils.equals("123",userDTO.getPassword())){
result.put("code","100");
result.put("token",userDTO.getUserName()+""+userDTO.getPassword());
result.put("message","登录成功");
return result;
}
result.put("code","-100");

@JSONField使用

*/
@Data
public class HistoryPassword implements Serializable {

/**

*/
@JSONField(name = "id")
private String id;
/**
* 密码
*/
@JSONField(name = "pass_word")
private String passWord;
/**
* 创建时间
*/
@JSONField(name = "create_time")
private Date createTime;
/**
* 修改时间
*/
private Date updateTime;
/**
* 密码创建用户
*/
@JSONField(name = "create_user")
private String createUser;
}
