FastJson与Gson小测试
最近用到Json来传输数据,找到两个比较简单的工具 Gson 和 FastJson
随便测试一下两个工具的效率~
1 package com.json.fast; 2 3 import java.util.ArrayList; 4 import java.util.List; 5 6 import com.alibaba.fastjson.JSON; 7 import com.demo.module.Student; 8 import com.google.gson.Gson; 9 import com.google.gson.reflect.TypeToken;10 11 12 public class FastJson {13 public static void main(String[] args) {14 15 16 List<Student> list=new ArrayList<Student>();17 18 for (int i = 0; i < 500000; i++) {19 Student student=new Student();20 student.setId(i);21 student.setName("Name"+i);22 student.setAge(i);23 student.setSex("boy");24 25 list.add(student);26 }27 28 String json=JSON.toJSONString(list);29 for (int i = 0; i < 10; i++) { 30 long time_start = System.currentTimeMillis();31 JSON.toJSONString(list); 32 long time_end = System.currentTimeMillis();33 System.out.println("FastJson to JSON 用时:"+(time_end-time_start));34 }35 System.out.println();36 for (int i = 0; i < 10; i++) { 37 long time_start = System.currentTimeMillis();38 JSON.parseArray(json, Student.class); 39 long time_end = System.currentTimeMillis();40 System.out.println("FastJson to List 用时:"+(time_end-time_start));41 }42 System.out.println();43 44 Gson gson=new Gson(); 45 for (int i = 0; i < 10; i++) { 46 long time_startg = System.currentTimeMillis();47 gson.toJson(list);48 long time_endg = System.currentTimeMillis();49 System.out.println("Gson to JSON 用时:"+(time_endg-time_startg));50 }51 System.out.println();52 for (int i = 0; i < 10; i++) { 53 long time_startg = System.currentTimeMillis();54 gson.fromJson(json,new TypeToken<List<Student>>(){}.getType());55 long time_endg = System.currentTimeMillis();56 System.out.println("Gson to List 用时:"+(time_endg-time_startg));57 }58 }59 }
