fastjson针对map的简单测试

能够很好的支持复杂对象序列化和反序列化的json工具有阿里巴巴的fastjson和Google的gson，但是两个还不一样。gson参见：http://www.52php.cn/article/p-npymqfwk-rw.html

下面是我对fastjson针对map类型的简单测试结果：

package com.yjl.javabase.json;


import com.alibaba.fastjson.JSON;

import java.util.Date;
import java.util.HashMap;
import java.util.Map;

public class FastJsonTest {
	public static void main(String[] args) {
		Map<String,Student> stringStudentMap = new HashMap<>();
		Student s1 = new Student(11,"aaa","bbb",111.111,new Date());
		Student s2 = new Student(22,"cccc","ddddd",222.222,new Date());
		stringStudentMap.put("one",s1);
		stringStudentMap.put("tow",s2);
		System.out.println(JSON.toJSONString(stringStudentMap));
		System.out.println();
		Map<Student,String> studentStringMap = new HashMap<>();
		studentStringMap.put(s1,"three");
		studentStringMap.put(s2,"four");
		System.out.println(JSON.toJSONString(studentStringMap));
	}
}

class Student {
	private int age;
	private String firstName;
	private String lastName;
	private double heigth;
	private Date birth;

	public Student(int age,String firstName,String lastName,double heigth,Date birth) {
		this.age = age;
		this.firstName = firstName;
		this.lastName = lastName;
		this.heigth = heigth;
		this.birth = birth;
	}

	public Date getBirth() {
		return birth;
	}

	public void setBirth(Date birth) {
		this.birth = birth;
	}

	public int getAge() {
		return age;
	}

	public void setAge(int age) {
		this.age = age;
	}

	public String getFirstName() {
		return firstName;
	}

	public void setFirstName(String firstName) {
		this.firstName = firstName;
	}

	public String getLastName() {
		return lastName;
	}

	public void setLastName(String lastName) {
		this.lastName = lastName;
	}

	public double getHeigth() {
		return heigth;
	}

	public void setHeigth(double heigth) {
		this.heigth = heigth;
	}
}

{"one":{"age":11,"birth":1486782339687,"firstName":"aaa","heigth":111.111,"lastName":"bbb"},"tow":{"age":22,"firstName":"cccc","heigth":222.222,"lastName":"ddddd"}}

{{"age":11,"lastName":"bbb"}:"three",{"age":22,"lastName":"ddddd"}:"four"}
