SSM项目集成Redis

1、导入jar包

　　Java对Redis的操作依赖于jedis，所以我们需要导入jedis的jar包

commons-pool2-2.3
jedis-2.7.0

2、编写连接池工具类

package top.ftime.wk.utils;

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

import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;

/**
 * @author: JAVASM
 * @className: JedisUtil
 * @description:
 * @date: 2021/6/6 22:55
 * @version: 0.1
 * @since: jdk1.8
 */
public class JedisUtil {

    private static JedisPool jedisPool;

    static {
        InputStream inputStream = JedisUtil.class.getClassLoader().getResourceAsStream("redis.properties");
        Properties properties = new Properties();
        try {
            properties.load(inputStream);
            JedisPoolConfig config = new JedisPoolConfig();
            //最大空闲数
            config.setMaxIdle(Integer.parseInt(properties.getProperty("maxIdle")));
            //最大连接数
            config.setMaxTotal(Integer.parseInt(properties.getProperty("maxTotal")));
            jedisPool = new JedisPool(config, properties.getProperty("host"),Integer.parseInt(properties.getProperty("port")));
        } catch (IOException e) {
            throw new RuntimeException("配置文件加载失败");
        }
    }

    /**
     * 获得Jedis
     * @return
     */
    public static Jedis getJedis(){
        return jedisPool.getResource();
    }

    /**
     * 释放资源
     * @param jedis
     */
    public static void release(Jedis jedis){
        //这个表示当前jedis连接  放到我们连接池中，并不是关闭了
        jedis.close();
    }

}

3、使用

                //redis 缓存
                jedis.set(email, code);
                //两分钟后自动删除
                jedis.expire(email, 120);
                //取值
                jedis.get(email);  
                //登录成功后，手动删除
                jedis.del(email);
