原文地址：https://www.i847.cn/article/8.html

RedisTemplate序列化工具效率对比：

1.JdkSerializationRedisSerializer

2.GenericJackson2JsonRedisSerializer

3.Jackson2JsonRedisSerializer

测试代码片段：

 

@Test
public void test7(){
  Page page = sysMessageEventDao.findAll(Pages.Helper.pageable(1, 200, null));
  List list = page.getContent();
  JdkSerializationRedisSerializer j = new JdkSerializationRedisSerializer();
  GenericJackson2JsonRedisSerializer g = new GenericJackson2JsonRedisSerializer();
  Jackson2JsonRedisSerializer j2 = new Jackson2JsonRedisSerializer(List.class);
  TimeTest tt = new TimeTest();
  tt.setStartTime();
  byte[] bytesJ = j.serialize(list);
  tt.setEndTime();
  System.out.println("JdkSerializationRedisSerializer序列化时间："+tt.getExcuteTime() + "ms,序列化后的长度：" + bytesJ.length);
  tt.setStartTime();
  j.deserialize(bytesJ);
  tt.setEndTime();
  System.out.println("JdkSerializationRedisSerializer反序列化时间："+tt.getExcuteTime());
  tt.setStartTime();
  byte[] bytesG = g.serialize(list);
  tt.setEndTime();
  System.out.println("GenericJackson2JsonRedisSerializer序列化时间："+tt.getExcuteTime() + "ms,序列化后的长度：" + bytesG.length);
  tt.setStartTime();
  g.deserialize(bytesG);
  tt.setEndTime();
  System.out.println("GenericJackson2JsonRedisSerializer反序列化时间："+tt.getExcuteTime());
  tt.setStartTime();
  byte[] bytesJ2 = j2.serialize(list);
  tt.setEndTime();
  System.out.println("Jackson2JsonRedisSerializer序列化时间："+tt.getExcuteTime() + "ms,序列化后的长度：" + bytesJ2.length);
  tt.setStartTime();
  j2.deserialize(bytesJ2);
  tt.setEndTime();
  System.out.println("Jackson2JsonRedisSerializer反序列化时间："+tt.getExcuteTime());
}

测试数据（总共200条记录的List集合），单条类似：

{"channel":"USER_LOGIN@30-9C-23-83-D0-9C","createTime":1526973952000,"doneHost":"192.168.80.10:62016","doneServer":"he-pm","doneTime":1526973952000,"eventInfoJson":"{\"userName\":\"Mos.Jiang\",\"targetId\":\"250524c0-8869-4fc2-a4aa-278a5a5b3197\",\"localId\":\"250524c0-8869-4fc2-a4aa-278a5a5b3197\",\"first\":\"您好，您账号已经登录\",\"keyword1\":\"2018年05月22日 15:25\",\"keyword2\":\"127.0.0.1\",\"remark\":\"如果本次登录不是您本人所为，说明您的帐号已经被盗！为减少您的损失，请立即联系客服 4008271580。\"}","hasDone":1,"id":"006bdac0-0ba0-498d-b654-28fa6038f747","sendCount":1,"sendTime":1526973952000,"senderInfo":"com.mj.he800.pm.service.user.UserBaseInfoService#userLogin-215"}

测试结果：

JdkSerializationRedisSerializer序列化时间：11,序列化后的长度：94551
JdkSerializationRedisSerializer反序列化时间：15
GenericJackson2JsonRedisSerializer序列化时间：18,序列化后的长度：151108
GenericJackson2JsonRedisSerializer反序列化时间：14
Jackson2JsonRedisSerializer序列化时间：5,序列化后的长度：125489
Jackson2JsonRedisSerializer反序列化时间：3

简单地可以看出，Jackson2JsonRedisSerializer序列化和反序列化效率高，JdkSerializationRedisSerializer序列化后的结果最短
