fastjson解析任意json

fastjson解析任意json到bean

解析案例的代码

package com.base.config;

import java.util.List;

import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;

public class JsonParse {
    
    public static void main(String[] args) {
        
        String arrJson = "[{"id":1,"mobile":15809619172},{"id":2,"mobile":14588827746}]";
        List<Student> stus = JSONArray.parseArray(arrJson, Student.class);
        
        System.out.println("array json的解析结果：");
        
        for (Student stu : stus) {
            System.out.println(stu);
        }
        
        String beanJson = "{"id":1,"mobile":15809619172}";
        Student stu = JSONObject.parseObject(beanJson, Student.class);
        System.out.println("beanjson的解析结果：");
        System.out.println(stu);
        
    }

}

Student的代码

package com.base.config;

public class Student {
    private int id;
    private String mobile;

    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getMobile() {
        return mobile;
    }
    public void setMobile(String mobile) {
        this.mobile = mobile;
    }
    
    @Override
    public String toString() {
        return "Student [id=" + id + ", mobile=" + mobile + "]";
    }

}

程序运行结果

array json的解析结果：
Student [id=1, mobile=15809619172]
Student [id=2, mobile=14588827746]
beanjson的解析结果：
Student [id=1, mobile=15809619172]

这样解析效率很高，而且代码非常简单。比json-lib库要简化非常多。所以强烈推荐使用fastjson.
