> SpringBoot集成Redis很简单，只需要简单的几步就可以了。（假设已经安装好了redis）

1.添加依赖

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>

2.写redis的配置文件

spring:
        redis:
            host: redis的ip地址
            port: 6379
            database: 0#选择数据库
            #password:如果有密码，这里写密码
            pool:
              max-active: 8
              max-idle: 500
              min-idle: 0

3 . redis的dao

@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 = template.opsForValue();
            return ops.get(key);
        }
    
    }

4 . 测试

@RunWith(SpringRunner.class)
    @SpringBootTest
    @ContextConfiguration
    public class SpringbootRedisApplicationTests { 
        public static Logger logger= LoggerFactory.getLogger(SpringbootRedisApplicationTests.class);
        @Test
        public void contextLoads() {
        }
    
        @Autowired
        private RedisDao redisDao;
        @Test
        public void testRedis(){
            redisDao.setKey("name","redis");
            redisDao.setKey("age","dddddddd");
            logger.info(redisDao.getValue("name"));
            logger.info(redisDao.getValue("age"));
        }
    }

> 注意，测试用例要放在SpringbootApplicationTests的同级目录下

5 . 结果

> 2018-07-12 21:21:00.999 INFO 9604 — \[ main\] c.s.s.SpringbootRedisApplicationTests : redis  
> 2018-07-12 21:21:01.000 INFO 9604 — \[ main\] c.s.s.SpringbootRedisApplicationTests : dddddddd
