1、创建user.json文件

 {
	"code": 200,
	"message": "查询成功",
	"data": [
		{
			"id": 1,
			"name": "张三"
		},
		{
			"id": 2,
			"name": "李四"
		},
		{
			"id": 3,
			"name": "王五"
		}
	]
}  

2、创建java对象

 import lombok.Data;

@Data
public class  Request Result {
    private int code;
    private String message;
    private Object data;
}  

3、反序列化json字符串为java对象

 private  static  RequestResult read File Data() throws IO Exception  {
    File file = new File("D:user.json");
    ObjectMapper mapper = new ObjectMapper();
    return mapper.readValue(file, RequestResult.class);
}
