redis yml

spring:
  redis:

    host: 10.0.0.163
    port: 6379
    timeout: 3000
    pool:
      # 连接池最大连接数（使用负值表示没有限制）
      max-active: 8

      max-wait: -1
      # 连接池中的最大空闲连接
      max-idle: 8
      # 连接池中的最小空闲连接
      min-idle: 0

@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport {

    @Value("${redis-timeout}")
    private Long redisTimeout;

    //缓存管理器
    @Bean

为了方便使用将redis写成工具包

@Component
public class RedisUtil {

    @Autowired
    private RedisTemplate redisTemplate;

    /**
     * @Description: 批量删除缓存
     * @Author: hj
     * @Date: 17:13 2017/10/24
     */
    public void remove(final String... keys) {
        for (String key : keys) {
            remove(key);
        }
    }

    /**
     * @Description: 批量删除缓存(通配符)
     * @Author: hj
     * @Date: 16:52 2017/10/24
     */
    public void removePattern(final String pattern) {
        Set<Serializable> keys = redisTemplate.keys(pattern);
        if (keys.size() > 0)
            redisTemplate.delete(keys);
    }

    /**
     * @Description: 删除缓存
     * @Author: hj
     * @Date: 16:51 2017/10/24
     */
    public void remove(final String key) {
        if (exists(key)) {
            redisTemplate.delete(key);
        }
    }

    /**
     * @Description: 判断缓存中是否有对应的value
     * @Author: hj
     * @Date: 16:50 2017/10/24
     */
    public boolean exists(final String key) {
        return redisTemplate.hasKey(key);
    }

    /**

     * @Author: hj
     * @Date: 16:49 2017/10/24
     */
    public Object get(final String key) {
        return redisTemplate.opsForValue().get(key);
    }

    /**

        boolean result = false;
        try {
            redisTemplate.opsForValue().set(key, value);
            result = true;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return result;
    }

    /**
     * @Description: 写入缓存(可以配置过期时间)

     * @Date: 16:46 2017/10/24
     */
    public boolean set(final String key, Object value, Long expireTime) {
        boolean result = false;
        try {
            redisTemplate.opsForValue().set(key, value);
            redisTemplate.expire(key, expireTime, TimeUnit.SECONDS);
            result = true;
        } catch (Exception e) {
            e.printStackTrace();

Controller就不写了,测试Service

@Service
public class TestService {

    @Autowired
    private TestMapper testMapper;

    @Autowired
    private RedisUtil redisUtil;

    public Test test1(Test test) {
        Test mytest = testMapper.getOneById(test.getId());
        redisUtil.set("test",mytest,10L);  //10秒过期
        return mytest;
    }

    public Test test2() {
        return (Test)redisUtil.get("test");
    }
}
