springMVC 接收List类型的参数 postMan测试

1 对象中包含list类型的参数

1.1 后端的数据类型

@Data
public class Answer implements Serializable {

    private static final long serialVersionUID = 2939516508271512897L;
    private List disks;
}

1.2 Controlle层接收方式

    @RequestMapping(value = "/getAnswer",method = RequestMethod.GET)
    public void getAnswer(@RequestBody Answer answer)throws Exception{
        System.out.println("======="+ JSON.toJSONString(answer));
        System.out.println("this is good ");
        return;
    }

1.3 postMan参数设置

1.4 postMan 参数设置

{
  "disks": [
    {
      "index": "1",
      "type": "string"
    },
    {
      "index": "2",
      "type": "string"
    }
  ]
}

1.5 结果验证
