2.新建项目，pom.xml如下：

<?xml version="1.0" encoding="UTF-8"?>

# REDIS (RedisProperties)
    # Redis数据库索引（默认为0）
    spring.redis.database=0
    # Redis服务器地址
    spring.redis.host=123.207.179.33
    # Redis服务器连接端口
    spring.redis.port=6379
    # Redis服务器连接密码（默认为空）
    spring.redis.password=

    # 连接池中的最小空闲连接

    spring.redis.timeout=6000

4.RedisDao

package com.gwd.dao;
    import java.util.concurrent.TimeUnit;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.data.redis.core.StringRedisTemplate;
    import org.springframework.data.redis.core.ValueOperations;
    import org.springframework.stereotype.Repository;
    /** 
    * @ProjectName spring-boot-redis
    * @author JackHisen(gu.weidong) 
    * @Date 2018年2月21日 下午7:59:17    
    * @Version 1.0 
    * @Description:
    */
    @Repository
    public class RedisDao {
    	@Autowired
        private StringRedisTemplate template;
    
        public  void setKey(String key,String value){
            ValueOperations<String, String> ops = template.opsForValue();
            ops.set(key,value,1, TimeUnit.MINUTES);//1分钟过期
        }
    
        public String getValue(String key){
            ValueOperations<String, String> ops = this.template.opsForValue();
            return ops.get(key);
        }
    }

5.TestController

package com.gwd.controller;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    import com.gwd.dao.RedisDao;
    /** 
    * @ProjectName spring-boot-redis
    * @author JackHisen(gu.weidong) 
    * @Date 2018年2月21日 下午8:00:27    
    * @Version 1.0 
    * @Description:
    */
    @RestController
    public class TestController {
    	@Autowired
        RedisDao redisDao;
        @RequestMapping("/testRedis")
        public String testRedis(){
        	System.out.println("------------------------");
            redisDao.setKey("name","gwd");
            redisDao.setKey("age","18");
           System.out.println(redisDao.getValue("name"));
           System.out.println(redisDao.getValue("age"));
           return redisDao.getValue("name")+"今年"+redisDao.getValue("age")+"岁了！";
        }
    }

6.访问http://localhost:8080/testRedis
