Gson和Fastjson

1。PersonBean

package com.louis.fastjsondemo;

/** * Created by Administrator on 2016/2/26. */
public class PersonBean {

    private int id;
    private String name;
    private String address;
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public PersonBean() {
        super();
        // TODO Auto-generated constructor stub
    }
    public PersonBean(int id,String name,String address) {
        super();
        this.id = id;
        this.name = name;
        this.address = address;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getAddress() {
        return address;
    }
    public void setAddress(String address) {
        this.address = address;
    }
    @Override
    public String toString() {
        return "PersonBean [id=" + id + ",name=" + name + ",address=" + address + "]";
    }
