application配置：

spring:
  application:
    name: springbootdemo
  redis:
    # Redis数据库索引（默认为0）
    database: 0
    # Redis服务器地址
    host: 127.0.0.1
    # Redis服务器连接端口
    port: 6379
    jedis:
      pool:
        # 连接池中的最小空闲连接
        min-idle: 0
        # 连接池中的最大空闲连接
        max-idle: 10
        # 连接池最大连接数（使用负值表示没有限制）
        max-active: 10
        # 连接池最大阻塞等待时间（使用负值表示没有限制）
        max-wait: -1
        testOnBorrow: true
        testWhileIdle: true
        minEvictableIdleTimeMills: 60000
        timeBetweenEvictionRunsMillis: 30000
        numTestsPerEvictionRun: -1
    # 连接超时时间（毫秒）
    timeout: 5000

RedisConfig相关代码：

    @Bean
    public JedisPoolConfig jedisPoolConfig(){
        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();

        jedisPoolConfig.setMaxIdle(maxIdle);
        jedisPoolConfig.setMaxWaitMillis(maxWaitMillis);
        jedisPoolConfig.setTestWhileIdle(testWhileIdle);
        jedisPoolConfig.setTestOnBorrow(testOnBorrow);
        jedisPoolConfig.setMinEvictableIdleTimeMillis(minEvictableIdleTimeMills);
        jedisPoolConfig.setTimeBetweenEvictionRunsMillis(timeBetweenEvictionRunsMillis);
        jedisPoolConfig.setNumTestsPerEvictionRun(numTestsPerEvictionRun);
        jedisPoolConfig.setTestOnCreate(true);
        jedisPoolConfig.setTestOnReturn(true);
        return jedisPoolConfig;
    }

    @Bean
    public RedisConnectionFactory redisConnectionFactory(JedisPoolConfig jedisPoolConfig) {
        RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration();
        //设置redis服务器的host或者ip地址
        redisStandaloneConfiguration.setHostName(host);
        redisStandaloneConfiguration.setPort(port);
        //获得默认的连接池构造
        //这里需要注意的是，edisConnectionFactoryJ对于Standalone模式的没有（RedisStandaloneConfiguration，JedisPoolConfig）的构造函数，对此
        //我们用JedisClientConfiguration接口的builder方法实例化一个构造器，还得类型转换
        JedisClientConfiguration.JedisPoolingClientConfigurationBuilder jpcf = (JedisClientConfiguration.JedisPoolingClientConfigurationBuilder) JedisClientConfiguration.builder();
        //修改我们的连接池配置
        jpcf.poolConfig(jedisPoolConfig);
        //通过构造器来构造jedis客户端配置
        JedisClientConfiguration jedisClientConfiguration = jpcf.build();

        return new JedisConnectionFactory(redisStandaloneConfiguration, jedisClientConfiguration);
    }

    /**
     * @Description: 防止redis入库序列化乱码的问题
     * @return     返回类型
     * @date 2018/4/12 10:54
    */
    @Bean
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory){
        RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<Object, Object>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        redisTemplate.setKeySerializer(new StringRedisSerializer());//key序列化
        redisTemplate.setValueSerializer(new Jackson2JsonRedisSerializer(Object.class));  //value序列化
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashValueSerializer(new Jackson2JsonRedisSerializer(Object.class));
        redisTemplate.setDefaultSerializer(new Jackson2JsonRedisSerializer(Object.class));

        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

redis工具类：

@Component
public class RedisUtil {

    @Autowired
    private RedisTemplate redisTemplate;

    /**
     * set集合获取
     * @param key
     * @return
     */
    public Set<Object> getMembers(String key){
        SetOperations<String, Object> set = redisTemplate.opsForSet();
        return set.members(key);
    }

    /**
     * 集合set中是否存在目标对象
     * @param key
     * @param value
     * @return
     */
    public Boolean isMember(String key, Object value){
        return redisTemplate.opsForSet().isMember(key, value);
    }

    public void addMember(String key, Object value) {
        redisTemplate.opsForSet().add(key, value);
    }

    public void delMember(String key, Object value) {
        redisTemplate.opsForSet().remove(key, value);
    }

    public Long getExpire(String key) {
        return redisTemplate.getExpire(key,TimeUnit.MILLISECONDS);
    }

    public void setExpire(String key, Integer time) {
        redisTemplate.expire(key, time, TimeUnit.MILLISECONDS);
    }

    public void setValue(String key, Object value) {
        redisTemplate.opsForValue().set(key, value);
    }

    public Object getValue(String key) {
        return redisTemplate.opsForValue().get(key);
    }

    public void delValue(String key) {
        redisTemplate.opsForValue().getOperations().delete(key);
    }
}

测试用的controller：

@Slf4j
@RestController
@RequestMapping("redis")
public class RedisDemoController {
    @Autowired
    private RedisUtil redisUtil;

    @RequestMapping(value = "/setRedis", method = RequestMethod.POST)
    public String setRedis(String value) {
        String result;
        try {
            redisUtil.setValue("redis_key", value);
            result = "redis设置成功";
        } catch (Exception e) {
            result = "redis设置失败:" + e.getMessage();
        }
        return result;
    }


    @RequestMapping(value = "/getRedis", method = RequestMethod.GET)
    public String getRedis() {
        String result;
        try {
            String value = (String) redisUtil.getValue("redis_key");
            result = "redis读取成功:" + value;
        } catch (Exception e) {
            result = "redis读取失败:" + e.getMessage();
        }
        return result;
    }
}
