Spring Boot中的JSON技术-时间处理
Spring Boot中的JSON技术-时间处理
1、准备
1.1、数据库
1.2、Model
package com.wnx.mall.tiny.mbg.model;
import com.fasterxml.jackson.annotation.JsonFormat;
import io.swagger.annotations.ApiModelProperty;
import java.io.Serializable;
import java.util.Date;
public class UmsAdmin implements Serializable {
private Long id;
private String username;
private String password;
@ApiModelProperty(value = "头像")
private String icon;
@ApiModelProperty(value = "邮箱")
private String email;
@ApiModelProperty(value = "昵称")
private String nickName;
@ApiModelProperty(value = "备注信息")
private String note;
@ApiModelProperty(value = "创建时间")
private Date createTime;
@ApiModelProperty(value = "最后登录时间")
private Date loginTime;
@ApiModelProperty(value = "帐号启用状态：0->禁用；1->启用")
private Integer status;
private static final long serialVersionUID = 1L;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getIcon() {
return icon;
}
public void setIcon(String icon) {
this.icon = icon;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getNickName() {
return nickName;
}
public void setNickName(String nickName) {
this.nickName = nickName;
}
public String getNote() {
return note;
}
public void setNote(String note) {
this.note = note;
}
public Date getCreateTime() {
return createTime;
}
public void setCreateTime(Date createTime) {
this.createTime = createTime;
}
public Date getLoginTime() {
return loginTime;
}
public void setLoginTime(Date loginTime) {
this.loginTime = loginTime;
}
public Integer getStatus() {
return status;
}
public void setStatus(Integer status) {
this.status = status;
}
@Override
public String toString() {
StringBuilder sb = new StringBuilder();
sb.append(getClass().getSimpleName());
sb.append(" [");
sb.append("Hash = ").append(hashCode());
sb.append(", id=").append(id);
sb.append(", username=").append(username);
sb.append(", password=").append(password);
sb.append(", icon=").append(icon);
sb.append(", email=").append(email);
sb.append(", nickName=").append(nickName);
sb.append(", note=").append(note);
sb.append(", createTime=").append(createTime);
sb.append(", loginTime=").append(loginTime);
sb.append(", status=").append(status);
sb.append(", serialVersionUID=").append(serialVersionUID);
sb.append("]");
return sb.toString();
}
}
1.3、Controller
package com.wnx.mall.tiny.controller;
import com.wnx.mall.tiny.mbg.model.UmsAdmin;
import com.wnx.mall.tiny.service.UmsAdminService;
import io.swagger.annotations.Api;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import javax.annotation.Resource;
@Api(tags = "JsonController", description = "SpringBootJSON测试")
@Controller
@RequestMapping("/json")
public class JsonController {
@Resource
private UmsAdminService adminService;
@GetMapping("findById/{id}")
@ResponseBody
public UmsAdmin findById(@PathVariable(name = "id")Long id) {
UmsAdmin umsAdmin = adminService.findById(id);
System.out.println(umsAdmin);
return umsAdmin;
}
}
观察日期返回得到JSON格式！
{
"id": 1,
"username": "test",
"password": "$2a$10$NZ5o7r2E.ayT2ZoxgjlI.eJ6OEYqjH7INR/F.mXDbjZJi9HF0YCVG",
"icon": "http://macro-oss.oss-cn-shenzhen.aliyuncs.com/mall/images/20180607/timg.jpg",
"email": "[email protected]",
"nickName": "测试账号",
"note": null,
"createTime": "2018-09-29T05:55:30.000+0000",
"loginTime": "2018-09-29T05:55:39.000+0000",
"status": 1
}
可看到时间默认以2018-09-29T05:55:30.000+0000的形式输出，如果想要改变这个默认行为，我们有三种如下解决手段！
2、解决
2.1、方法1：配置加强的ObjectMapper
package com.wnx.mall.tiny.config;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.text.SimpleDateFormat;
@Configuration
public class JacksonConfig {
@Bean
public ObjectMapper getObjectMapper(){
ObjectMapper mapper = new ObjectMapper();
mapper.setDateFormat(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"));
return mapper;
}
}
2.2、方法2:Model加注解@JsonFormat
package com.wnx.mall.tiny.mbg.model;
import com.fasterxml.jackson.annotation.JsonFormat;
import io.swagger.annotations.ApiModelProperty;
import java.io.Serializable;
import java.util.Date;
public class UmsAdmin implements Serializable {
private Long id;
private String username;
private String password;
@ApiModelProperty(value = "头像")
private String icon;
@ApiModelProperty(value = "邮箱")
private String email;
@ApiModelProperty(value = "昵称")
private String nickName;
@ApiModelProperty(value = "备注信息")
private String note;
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
@ApiModelProperty(value = "创建时间")
private Date createTime;
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
@ApiModelProperty(value = "最后登录时间")
private Date loginTime;
@ApiModelProperty(value = "帐号启用状态：0->禁用；1->启用")
private Integer status;
private static final long serialVersionUID = 1L;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getIcon() {
return icon;
}
public void setIcon(String icon) {
this.icon = icon;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getNickName() {
return nickName;
}
public void setNickName(String nickName) {
this.nickName = nickName;
}
public String getNote() {
return note;
}
public void setNote(String note) {
this.note = note;
}
public Date getCreateTime() {
return createTime;
}
public void setCreateTime(Date createTime) {
this.createTime = createTime;
}
public Date getLoginTime() {
return loginTime;
}
public void setLoginTime(Date loginTime) {
this.loginTime = loginTime;
}
public Integer getStatus() {
return status;
}
public void setStatus(Integer status) {
this.status = status;
}
@Override
public String toString() {
StringBuilder sb = new StringBuilder();
sb.append(getClass().getSimpleName());
sb.append(" [");
sb.append("Hash = ").append(hashCode());
sb.append(", id=").append(id);
sb.append(", username=").append(username);
sb.append(", password=").append(password);
sb.append(", icon=").append(icon);
sb.append(", email=").append(email);
sb.append(", nickName=").append(nickName);
sb.append(", note=").append(note);
sb.append(", createTime=").append(createTime);
sb.append(", loginTime=").append(loginTime);
sb.append(", status=").append(status);
sb.append(", serialVersionUID=").append(serialVersionUID);
sb.append("]");
return sb.toString();
}
}
2.3、方法3:application.yaml中配置spring.jackson.date-format全局
server:
port: 8080
spring:
datasource:
url: jdbc:mysql://localhost:3306/mall?useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai
username: root
password: root
jackson:
date-format: yyyy-MM-dd HH:mm:ss
mybatis:
mapper-locations:
- classpath:mapper/*.xml
- classpath*:com/**/mapper/*.xml
3、说明
三种手段则一个，都能得到如下效果！
