CSDN上目前最简单的Redis封装使用

废话少说,直接代码(此次封装中包括了String和Hash中最常用的set,get,del)
首先导入2个Jar包,接下来的事情就简单了
commons-pool2-2.3.jar
jedis-2.7.0.jar

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

        import java.util.ResourceBundle;
//以上为导包内容
public class JedisUtils {

    private static JedisPool pool;
    //连接池的创建:放到静态代码里,一个应用里只要有一个连接池对象即可,用完即可释放
    static {
        /* 1.创建连接池的配置信息对象
         配置文件中包含了4种必备要素
           1. host ip地址
           2. port    端口
           3. maxTotal     最大连接数
           4. maxidle   最大空闲连接
        ----->从src中读取配置文件(极简),可以有效的解决硬编码问题   */
        ResourceBundle bundle = ResourceBundle.getBundle(\"jedis\");

        JedisPoolConfig Config = new JedisPoolConfig();
