17.2.1 在Windows下安装Redis

https://github.com/ServiceStack/redis-windows/tree/master/downloads

 

redis-server redis.windows.conf

17.3.1 在Java程序中使用Redis

http://mvnrepository.com/artifact/redis.clients/jedis/2.9.0

         Java连接Redis

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 testJdedis(){   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   }}

       使用Redis连接池

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;        }

package com.ssm.chapter17.main;import com.ssm.chapter17.jedis.JedisTest;public class Chapter17Main {   public static void main(String[] args) {       testJedis();}   private static void testJedis() {       JedisTest jedisTest = new JedisTest();       jedisTest.testJdedis();   }}

17.3.2 在Spring中使用Redis

    使用Spring配置JedisPoolConfig对象

    配置JedisConnectionFactory

       配置Spring RedisTemplate

       使用Redis保存角色类对象

package com.ssm.chapter17.pojo;import java.io.Serializable;/** * 注意，对象要可序列化，需要实现Serializable接口，往往要重写serialVersionUID *  * @author zhongzh * */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;    }        }

        使用RedisTemplate保存Role对象

private static void testSpring() {       ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");       RedisTemplate redisTemplate = applicationContext.getBean(RedisTemplate.class);       Role role = new Role();       role.setId(1L);       role.setRoleName("role_name_1");       role.setNote("role_note_1");       redisTemplate.opsForValue().set("role_1", role);       Role role1 = (Role) redisTemplate.opsForValue().get("role_1");       System.out.println(role.getRoleName());   }

         使用SessionCallback接口

private static void testSessionCallback(){       ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");       RedisTemplate redisTemplate = applicationContext.getBean(RedisTemplate.class);       Role role = new Role();       role.setId(1);       role.setRoleName("role_name_1");       role.setNote("role_note_1");       SessionCallback
     
       sessionCallback = new SessionCallback
      
       () {        public Role execute(RedisOperations ops)                throws DataAccessException {            // TODO Auto-generated method stub            ops.boundValueOps("role_1").set(role);            return (Role) ops.boundValueOps("role_1").get();        }    };    Role savedRole = (Role) redisTemplate.execute(sessionCallback);    System.out.println(savedRole.getId());   }
      
     

应改为：

private static void testSessionCallback(){       ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");       RedisTemplate redisTemplate = applicationContext.getBean(RedisTemplate.class);       final Role role = new Role();       role.setId(1);       role.setRoleName("role_name_1");       role.setNote("role_note_1");       SessionCallback
     
       sessionCallback = new SessionCallback
      
       () {        public Role execute(RedisOperations ops)                throws DataAccessException {            // TODO Auto-generated method stub            ops.boundValueOps("role_1").set(role);            return (Role) ops.boundValueOps("role_1").get();        }    };    Role savedRole = (Role) redisTemplate.execute(sessionCallback);    System.out.println(savedRole.getId());   }
