SpringBoot2.0整合jackson配置日期格式化和反序列化的实现

浅沫记忆

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>
    <groupid>org.springframework.boot</groupid>
    <artifactid>spring-boot-starter-web</artifactid>
    <version>release</version>
    <scope>compile</scope>
  </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：
