一、redis资源池的使用

以maven工程为例
pom.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>org.example</groupId>
    <artifactId>redisDemo</artifactId>
    <version>1.0-SNAPSHOT</version>

    <properties>
        <maven.compiler.source>16</maven.compiler.source>
        <maven.compiler.target>16</maven.compiler.target>
    </properties>

    <dependencies>
        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>2.9.0</version>
        </dependency>
    </dependencies>

</project>

代码

package test;

import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;

/**
 * @title: redisDemo
 * @Author xiaoK
 * @Date: 2021/6/30 16:32
 * @Version 1.0
 */
public class redisDemo {
    public static void main(String[] args) {
        //构建redis资源池配置
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        
        //配置redis资源池
        jedisPoolConfig.setMaxTotal(1000);
        
        //根据jedisPoolConfig构建redis资源池
        JedisPool jedisPool = new JedisPool(jedisPoolConfig, "localhost", 6379);

        //在redis资源池里构建redis连接
        Jedis jedis = jedisPool.getResource();
        
        //对redis操作
        String result = jedis.get("abc");
        
        //将redis连接归还给redis资源池
        jedis.close();
    }
}

二、配置

redis资源池中的配置有很多，如下：
