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 }
