springboot

springboot默认自带json解析框架，默认使用jackson

 

SpringMVC

需要的jar包： 

 Controller：

@RequestMapping("/testJson")
public String testJson5(@RequestBody List<Person> persons) {
    System.out.println(persons);
    return "success";
}

使用Maven管理jar包时：

一、jackjson maven

<jackjson.version>2.8.8</jackjson.version>

<dependency>
  <groupId>com.fasterxml.jackson.core</groupId>
   <artifactId>jackson-core</artifactId>
   <version>${jackjson.version}</version>
</dependency>
<dependency>
   <groupId>com.fasterxml.jackson.core</groupId>
   <artifactId>jackson-annotations</artifactId>
   <version>${jackjson.version}</version>
</dependency>
<dependency>
   <groupId>com.fasterxml.jackson.core</groupId>
   <artifactId>jackson-databind</artifactId>
   <version>${jackjson.version}</version>
</dependency>

二、fastjson maven

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.32</version>
</dependency>

Ajax

function fun(){
    $.ajax({
        url:'/testAjax.action',
        data:"{'name':'xujie','age':'25'}",
        type:'POST',
        dataType:'json',  //告诉服务器，我要接收的是json格式数据
        contentType:'application/json'  //告诉服务器我发送的是json格式数据
    })
}
