Gson和Fastjson解析对比

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 + "]";
    }

}

2。Gson aty

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Gson gson = new Gson();
        // JavaBean数据
        PersonBean personBean = new PersonBean(1, "name1", "address1");
        String jsonString = gson.toJson(personBean);
        System.out.println("==1.jsonString=="+jsonString);
        // JavaBean数据解析
        PersonBean person = gson.fromJson(jsonString, PersonBean.class);
        System.out.println("==1.person=="+person);
        // List数据
        PersonBean person1 = new PersonBean(1001, "香港", "刘德华");

        PersonBean person2 = new PersonBean(1002, "韩国", "宋慧乔");

        List<PersonBean> persons = new ArrayList<PersonBean>();

        persons.add(person1);

        persons.add(person2);
        jsonString = gson.toJson(persons);
        System.out.println("==2.jsonString=="+jsonString);
        // List数据解析
        List<PersonBean> persons2 = gson.fromJson(jsonString, new TypeToken<List<PersonBean>>() {
        }.getType());
        System.out.println("==2.persons2=="+persons2);

        // List数据
        List<String> list = new ArrayList<String>();

        list.add("gson1");

        list.add("gson2");

        list.add("gson3");
        jsonString = gson.toJson(list);
        System.out.println("==3.jsonString=="+jsonString);
        // List数据解析
        List<String> list2 = gson.fromJson(jsonString, new TypeToken<List<String>>() {
        }.getType());
        System.out.println("==3.list2=="+list2);

        // List>数据
        Map<String, Object> map = new HashMap<String, Object>();

        map.put("key1", "value1");

        map.put("key2", "value2");

        Map<String, Object> map2 = new HashMap<String, Object>();

        map2.put("key1", 1);

        map2.put("key2", 2);

        List<Map<String, Object>> listm = new ArrayList<Map<String, Object>>();

        listm.add(map);

        listm.add(map2);
        jsonString = gson.toJson(listm);
        System.out.println("==4.jsonString=="+jsonString);
        List<Map<String, Object>> listm2 = gson.fromJson(jsonString, new TypeToken<List<Map<String, Object>>>() {
