     实体类：

Role

package com.ssm.chapter17.pojo; import java.io.Serializable; public class Role implements Serializable {
     private static final long serialVersionUID = 6977402643848374753L;    private long id;    private String roleName;    private String note;    public long getId() {
        return id;    }    public void setId(long id) {
        this.id = id;    }    public String getRoleName() {
        return roleName;    }    public void setRoleName(String roleName) {
        this.roleName = roleName;    }    public String getNote() {
        return note;    }    public void setNote(String note) {
        this.note = note;    } } 工具类：

testJedis

package com.ssm.chapter17.jedis; import redis.clients.jedis.Jedis; import redis.clients.jedis.JedisPool; import redis.clients.jedis.JedisPoolConfig; public class JedisTest {
     public void testJedis() {
        Jedis jedis = testPool().getResource();       // Jedis jedis = new Jedis("localhost", 6379); //连接Redis       // jedis.auth("password");//如果需密码       int i = 0;// 记录操作次数       try {
           long start = System.currentTimeMillis();// 开始毫秒数          while (true) {
              long end = System.currentTimeMillis();             if (end - start >= 1000) {// 当大于等于1000毫秒（相当于1秒）时，结束操作                break;             }             i++;             jedis.set("test" + i, i + "");          }       } finally {// 关闭连接          jedis.close();       }       System.out.println("redis每秒操作：" + i + "次");// 打印1秒内对Redis的操作次数    }    private JedisPool testPool() {
        JedisPoolConfig poolCfg = new JedisPoolConfig();       // 最大空闲数       poolCfg.setMaxIdle(50);       // 最大连接数       poolCfg.setMaxTotal(100);       // 最大等待毫秒数       poolCfg.setMaxWaitMillis(20000);       // 使用配置创建连接池       JedisPool pool = new JedisPool(poolCfg, "localhost");       // 从连接池中获取单个连接       Jedis jedis = pool.getResource();       // 如果需密码       // jedis.auth("password");       return pool;    } } 测试类，有原生的方法，也有Spring 提供的方法：
