RedisTemplate和JedisPool的效率对比
1、准备环境
1.1、安装本地Redis，并启动服务
如果还没安装的，可以参考博客：Windows系统本地安装Redis并设置服务自启动（图文）
1.2、创建Maven项目，并导入依赖
在pom.xml文件中加入以下依赖
<!-- 配置编译环境 -->
<build>
<plugins>
<!-- 处理项目JDK编译版本的问题 -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
<!-- 设置maven内置服务器为tomcat7 -->
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
</plugin>
</plugins>
</build>
<!-- 属性 -->
<properties>
<!-- 指定spring的版本 -->
<spring.version>5.1.9.RELEASE</spring.version>
<!-- 指定redis数据库的版本 -->
<redis.spring.version>1.8.23.RELEASE</redis.spring.version>
</properties>
<!-- 依赖 -->
<dependencies>
<!-- spring的IOC依赖 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-expression</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>${spring.version}</version>
</dependency>
<!-- spring单元测试的依赖 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>${spring.version}</version>
</dependency>
<!-- junit测试依赖 -->
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
</dependency>
<!-- junit版本超过4.11，需要手动加hamcrest的依赖 -->
<dependency>
<groupId>org.hamcrest</groupId>
<artifactId>hamcrest-core</artifactId>
<version>1.3</version>
<scope>test</scope>
</dependency>
<!-- redis和spring整合的依赖 -->
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-redis</artifactId>
<version>${redis.spring.version}</version>
</dependency>
<!-- 管理redis数据库连接的jedis连接池依赖 -->
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.9.0</version>
</dependency>
<!-- pool连接池依赖 -->
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-pool2</artifactId>
<version>2.7.0</version>
</dependency>
<dependency>
<groupId>commons-logging</groupId>
<artifactId>commons-logging</artifactId>
<version>1.2</version>
</dependency>
</dependencies>
1.3、准备Redis数据库参数的属性文件
在resources目录下创建redisConfig.properties属性文件，配置内容如下：
redis.host=127.0.0.1
redis.port=6379
redis.database=0
redis.password=dearest
redis.timeout=60000
redis.maxTotal=50
redis.maxIdle=20
redis.minIdle=8
redis.maxWaitMillis=60000
redis.testOnBorrow=true
redis.testOnReturn=true
1.4、准备Redis数据库在Spring框架中的xml配置文件
在resources目录下spring目录，在spring目录中创建applicationContext-redis.xml配置文件，配置内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
https://www.springframework.org/schema/context/spring-context.xsd">
<context:property-placeholder location="classpath:redisConfig.properties" />
<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
<property name="maxTotal" value="${redis.maxTotal}" />
<property name="maxIdle" value="${redis.maxIdle}" />
<property name="minIdle" value="${redis.minIdle}" />
<property name="maxWaitMillis" value="${redis.maxWaitMillis}" />
<property name="testOnBorrow" value="${redis.testOnBorrow}" />
<property name="testOnReturn" value="${redis.testOnReturn}" />
</bean>
<bean id="jedisPool" class="redis.clients.jedis.JedisPool">
<constructor-arg name="poolConfig" ref="jedisPoolConfig" />
<constructor-arg name="host" value="${redis.host}" />
<constructor-arg name="port" value="${redis.port}" />
<constructor-arg name="password" value="${redis.password}" />
<constructor-arg name="database" value="${redis.database}" />
<constructor-arg name="timeout" value="${redis.timeout}" />
</bean>
<bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
<property name="poolConfig" ref="jedisPoolConfig" />
<property name="hostName" value="${redis.host}" />
<property name="port" value="${redis.port}" />
<property name="database" value="${redis.database}" />
<property name="password" value="${redis.password}" />
</bean>
<!-- 序列化方式 -->
<bean id="jdkSerializationRedisSerializer" class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" />
<!-- 序列化方式 -->
<bean id="stringRedisSerializer" class="org.springframework.data.redis.serializer.StringRedisSerializer" />
<!-- Redis模板 -->
<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
<property name="connectionFactory" ref="jedisConnectionFactory" />
<property name="keySerializer" ref="stringRedisSerializer" />
<property name="hashKeySerializer" ref="stringRedisSerializer" />
<property name="valueSerializer" ref="jdkSerializationRedisSerializer" />
<property name="hashValueSerializer" ref="jdkSerializationRedisSerializer" />
</bean>
</beans>
2、开始测试
2.1、创建测试类
package com.zdrl.web.controller;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
@RunWith(value = SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:spring/applicationContext-redis.xml")
public class Demo {
@Autowired
private RedisTemplate<String, Object> redisTemplate;
@Autowired
private JedisPool jedisPool;
private final int num = 100000;
@Test
public void method1 () {
long time = 0;
System.out.println("RedisTemplate：");
for (int i = 0; i <= num; i++) {
long time1 = System.currentTimeMillis();
redisTemplate.opsForValue().set(i + "", i + "");
long time2 = System.currentTimeMillis();
time += (time2 - time1);
if (i == 10) {
System.out.println("10次：总时间" + time);
} else if (i == 100) {
System.out.println("100次：总时间" + time);
} else if (i == 500) {
System.out.println("500次：总时间" + time);
} else if (i == 1000) {
System.out.println("1000次：总时间" + time);
} else if (i == 5000) {
System.out.println("5000次：总时间" + time);
} else if (i == 10000) {
System.out.println("10000次：总时间" + time);
} else if (i == 100000) {
System.out.println("100000次：总时间" + time);
}
}
}
@Test
public void method2 () {
long time = 0;
Jedis jedis = jedisPool.getResource();
System.out.println("JedisPool：");
for (int i = 0; i <= num; i++) {
long time1 = System.currentTimeMillis();
jedis.set(i + "", i + "");
long time2 = System.currentTimeMillis();
time += (time2 - time1);
if (i == 10) {
System.out.println("10次：总时间" + time);
} else if (i == 100) {
System.out.println("100次：总时间" + time);
} else if (i == 500) {
System.out.println("500次：总时间" + time);
} else if (i == 1000) {
System.out.println("1000次：总时间" + time);
} else if (i == 5000) {
System.out.println("5000次：总时间" + time);
} else if (i == 10000) {
System.out.println("10000次：总时间" + time);
} else if (i == 100000) {
System.out.println("100000次：总时间" + time);
}
}
}
}
2.2、测试结果
RedisTemplate的执行效率如下：
JedisPool的执行效率如下：
3、结论
JedisPool的效率比RedisTemplate简直快不要太多。
当然，我这是在本地Redis测试，有时间的朋友，可以测试一下服务器上两者的执行效率。
