SpringBoot2.0整合jackson配置日期格式化和反序列化的实现
这篇文章主要介绍了SpringBoot2.0整合jackson配置日期格式化和反序列化的实现,小编觉得挺不错的,现在分享给大家,也给大家做个参考。一起跟随小编过来看看吧网上杂七杂八的说法不一,大多数都是抄来抄去,没有实践,近期在项目频繁遇到boot+jackson处理日期的问题,故开此贴。
首先是pom
<?xml version="1.0" encoding="utf-8"?>
<project xmlns="http://maven.apache.org/pom/4.0.0" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"
xsi:schemalocation="http://maven.apache.org/pom/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelversion>4.0.0</modelversion>
<groupid>io.cj.learning</groupid>
<artifactid>boot2exam</artifactid>
<version>0.0.1-snapshot</version>
<packaging>jar</packaging>
<name>boot2exam</name>
<description>demo project for spring boot</description>
<parent>
<groupid>org.springframework.boot</groupid>
<artifactid>spring-boot-starter-parent</artifactid>
<version>2.0.0.release</version>
<relativepath/> <!-- lookup parent from repository -->
</parent>
<properties>
<project.build.sourceencoding>utf-8</project.build.sourceencoding>
<project.reporting.outputencoding>utf-8</project.reporting.outputencoding>
<java.version>1.8</java.version>
</properties>
<dependencies>
<dependency>
<groupid>org.springframework.boot</groupid>
<artifactid>spring-boot-starter-data-redis</artifactid>
</dependency>
<dependency>
<groupid>org.springframework.boot</groupid>
<artifactid>spring-boot-starter-web</artifactid>
</dependency>
<dependency>
<groupid>org.springframework.boot</groupid>
<artifactid>spring-boot-starter-test</artifactid>
<scope>test</scope>
</dependency>
<dependency>

</dependency>
<dependency>
<groupid>org.springframework.boot</groupid>
<artifactid>spring-boot-starter-web</artifactid>
<version>release</version>
<scope>compile</scope>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupid>org.springframework.boot</groupid>
<artifactid>spring-boot-maven-plugin</artifactid>
</plugin>
</plugins>
</build>
</project>
然后是yml文件
(当然yml这东西很多人不喜欢,我也写了个properties版本的)
spring:
jackson:
#参数意义:
#jsoninclude.include.always 默认
#jsoninclude.include.non_default 属性为默认值不序列化
#jsoninclude.include.non_empty 属性为 空(””) 或者为 null 都不序列化
#jsoninclude.include.non_null 属性为null不序列化
default-property-inclusion: always
time-zone: gmt+8
date-format: yyyy-mm-dd hh:mm:ss
上面配置对应的properties文件版本:
#jackson相关配置
spring.jackson.date-format = yyyy-mm-dd hh:mm:ss
#时区必须要设置
spring.jackson.time-zone= gmt+8
#always的意思是即时属性为null,仍然也会输出这个key
spring.jackson.default-property-inclusion=always
然后来定义一个controller和java bean
controller:
package io.cj.learning.boot2exam.controller;
import io.cj.learning.boot2exam.model.dateformattest;
import org.springframework.web.bind.annotation.*;
import java.text.simpledateformat;
import java.util.date;
@restcontroller
@requestmapping(value="/test")
public class testcontroller {
/**
* 测试时间序列化, java.util.date 类型 -> string
* @return
*/
@requestmapping(value="/dateformattest", method = requestmethod.get)
@responsebody
public dateformattest dateformattest(){
dateformattest dateformattest = new dateformattest();
dateformattest.setintproperties(100);
dateformattest.setdateproperties(new date());
return dateformattest;
}
/**
* 测试时间反序列化 string -> java.util.date 类型
*/
@requestmapping(value="/dateformattest2" ,method = requestmethod.post)
public void dateformattest2(@requestbody dateformattest model){
simpledateformat sdf = new simpledateformat("yyyy-mm-dd hh:mm:ss");
system.out.println(model.getintproperties());
system.out.println(sdf.format(model.getdateproperties()));
system.out.println(model.getstrproperties());
}
}
java bean:
package io.cj.learning.boot2exam.model;
import java.util.date;
/**
* 一个model,里面带一个日期类型
*/
public class dateformattest {
private integer intproperties;
private date dateproperties;
private string strproperties;
public integer getintproperties() {
return intproperties;
}
public void setintproperties(integer intproperties) {
this.intproperties = intproperties;
}
public date getdateproperties() {
return dateproperties;
}
public void setdateproperties(date dateproperties) {
this.dateproperties = dateproperties;
}
public string getstrproperties() {
return strproperties;
}
public void setstrproperties(string strproperties) {
this.strproperties = strproperties;
}
}
启动主类:
package io.cj.learning.boot2exam;
import org.springframework.boot.springapplication;
import org.springframework.boot.autoconfigure.springbootapplication;
@springbootapplication
public class boot2examapplication {
public static void main(string[] args) {
springapplication.run(boot2examapplication.class, args);
}
}
测试:
试一下,首先是日期序列化, 请求一下试试
然后是反序列化,也请求一个试试:
