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 }
LIST to JSON 用时比较 FastJson to JSON 用时：1188 FastJson to JSON 用时：1034 FastJson to JSON 用时：1201 FastJson to JSON 用时：1450 FastJson to JSON 用时：712 FastJson to JSON 用时：1156 FastJson to JSON 用时：695 FastJson to JSON 用时：1142 FastJson to JSON 用时：680 FastJson to JSON 用时：1206 Gson to JSON 用时：1079 Gson to JSON 用时：1108 Gson to JSON 用时：905 Gson to JSON 用时：1097 Gson to JSON 用时：903 Gson to JSON 用时：1056 Gson to JSON 用时：905 Gson to JSON 用时：903 Gson to JSON 用时：1113 Gson to JSON 用时：897
JSON to LIST 用时比较 FastJson to List 用时：351 FastJson to List 用时：222 FastJson to List 用时：189 FastJson to List 用时：177 FastJson to List 用时：281 FastJson to List 用时：349 FastJson to List 用时：258 FastJson to List 用时：226 FastJson to List 用时：213 FastJson to List 用时：201 Gson to List 用时：1305 Gson to List 用时：745 Gson to List 用时：790 Gson to List 用时：864 Gson to List 用时：886 Gson to List 用时：1168 Gson to List 用时：907 Gson to List 用时：796 Gson to List 用时：914 Gson to List 用时：1206
