redis环境安装：

我使用的是docker容器安装，方便快捷。安装教程：

新建项目：springboot-redis ，打开pom.xml文件加入相关依赖

       springboot2.0的redis整合包多出lettuce连接池，需要commons-pool2，所以项目pom依赖要添加commons-pool2

<!--web-->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
		</dependency>
		<!--redis-->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-data-redis</artifactId>
		</dependency>
		<!-- 高版本redis的lettuce需要commons-pool2 -->
		<dependency>
			<groupId>org.apache.commons</groupId>
			<artifactId>commons-pool2</artifactId>
			<version>2.6.0</version>
		</dependency>

打开src/main/resoucs/application.properties配置文件加入redis相关配置

server.port=8082

# REDIS
# 连接工厂使用的数据库索引。
spring.redis.database=0  
# IP地址
spring.redis.host=10.24.247.23
# 端口
spring.redis.port=6379  
# 密码
spring.redis.password=123456
#连接超时时间
spring.redis.timeout= 10000ms
# 连接池最大连接数（使用负值表示没有限制）
spring.redis.lettuce.pool.max-active=8
# 连接池最大阻塞等待时间（使用负值表示没有限制）
spring.redis.lettuce.pool.max-wait=-1
# 连接池中的最大空闲连接
spring.redis.lettuce.pool.max-idle=8
# 连接池中的最小空闲连接
spring.redis.lettuce.pool.min-idle=0

新建config包以及新建redisConfig.java文件src\main\java\com\example\springbootredis\config\redisConfig.java，内容如下：

@Configuration
@EnableCaching // 开启缓存支持
public class RedisConfig extends CachingConfigurerSupport {
    /**
     * RedisTemplate配置
     */
    @Bean
    public RedisTemplate<String, Object> redisTemplate(LettuceConnectionFactory lettuceConnectionFactory) {
        // 设置序列化
        Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<Object>(
                Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(om);
        // 配置redisTemplate
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<String, Object>();
        redisTemplate.setConnectionFactory(lettuceConnectionFactory);
        RedisSerializer<?> stringSerializer = new StringRedisSerializer();
        redisTemplate.setKeySerializer(stringSerializer);// key序列化
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);// value序列化
        redisTemplate.setHashKeySerializer(stringSerializer);// Hash key序列化
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);// Hash value序列化
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

}

新建在src\main\java\com\example\springbootredis\utils\redisredisService.java工具类，写入我们常用的方法，内容如下：

@Component
public class RedisService {
    private Logger logger = LoggerFactory.getLogger(RedisService.class);
    @Autowired
    private RedisTemplate redisTemplate;

    /**
     * set value
     *
     * @param key
     * @param value
     * @return
     */
    public boolean set(final String key, Object value) {
        boolean result = false;
        try {
            ValueOperations<Serializable, Object> operations = redisTemplate.opsForValue();
            operations.set(key, value);
            result = true;
        } catch (Exception e) {
            logger.error("set error: key {}, value {}", key, value, e);
        }
        return result;
    }

    /**
     * set value with expireTime
     *
     * @param key
     * @param value
     * @param expireTime
     * @return
     */
    public boolean set(final String key, Object value, Long expireTime) {
        boolean result = false;
        try {
            ValueOperations<Serializable, Object> operations = redisTemplate.opsForValue();
            operations.set(key, value);
            redisTemplate.expire(key, expireTime, TimeUnit.SECONDS);
            result = true;
        } catch (Exception e) {
            logger.error("set error: key {}, value {},expireTime {}", key, value, expireTime, e);
        }
        return result;
    }

    /**
     * @param key
     * @return
     */
    public boolean exists(final String key) {
        return redisTemplate.hasKey(key);
    }

    /**
     * @param key
     * @return
     */
    public Object get(final String key) {
        Object result = null;
        ValueOperations<Serializable, Object> operations = redisTemplate.opsForValue();
        result = operations.get(key);
        return result;
    }

    /**
     * remove single key
     *
     * @param key
     */
    public void remove(final String key) {
        if (exists(key)) {
            redisTemplate.delete(key);
        }
    }

    /**
     * batch delete
     *
     * @param keys
     */
    public void remove(final String... keys) {
        for (String key : keys) {
            remove(key);
        }
    }

    /**
     * batch delete with pattern
     *
     * @param pattern
     */
    public void removePattern(final String pattern) {
        Set<Serializable> keys = redisTemplate.keys(pattern);
        if (keys.size() > 0) {
            redisTemplate.delete(keys);
        }
    }

    /**
     * hash set
     *
     * @param key
     * @param hashKey
     * @param value
     */
    public void hashSet(String key, Object hashKey, Object value) {
        HashOperations<String, Object, Object> hash = redisTemplate.opsForHash();
        hash.put(key, hashKey, value);
    }

    /**
     * hash get
     *
     * @param key
     * @param hashKey
     * @return
     */
    public Object hashGet(String key, Object hashKey) {
        HashOperations<String, Object, Object> hash = redisTemplate.opsForHash();
        return hash.get(key, hashKey);
    }

    /**
     * list push
     *
     * @param k
     * @param v
     */
    public void push(String k, Object v) {
        ListOperations<String, Object> list = redisTemplate.opsForList();
        list.rightPush(k, v);
    }

    /**
     * list range
     *
     * @param k
     * @param l
     * @param l1
     * @return
     */
    public List<Object> range(String k, long l, long l1) {
        ListOperations<String, Object> list = redisTemplate.opsForList();
        return list.range(k, l, l1);
    }

    /**
     * set add
     *
     * @param key
     * @param value
     */
    public void setAdd(String key, Object value) {
        SetOperations<String, Object> set = redisTemplate.opsForSet();
        set.add(key, value);
    }

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

    /**
     * ordered set add
     *
     * @param key
     * @param value
     * @param scoure
     */
    public void zAdd(String key, Object value, double scoure) {
        ZSetOperations<String, Object> zset = redisTemplate.opsForZSet();
        zset.add(key, value, scoure);
    }

    /**
     * rangeByScore
     *
     * @param key
     * @param scoure
     * @param scoure1
     * @return
     */
    public Set<Object> rangeByScore(String key, double scoure, double scoure1) {
        ZSetOperations<String, Object> zset = redisTemplate.opsForZSet();
        return zset.rangeByScore(key, scoure, scoure1);
    }

新建src\main\java\com\example\springbootredis\model\User.java对象，这里我使用了lombok插件，节省了get、set等方法的书写。

引入lombok依赖

<!--lombok-->
		<dependency>
			<groupId>org.projectlombok</groupId>
			<artifactId>lombok</artifactId>
			<version>1.16.22</version>
		</dependency>

当然idea开发工具使用lombok还需要安装插件哦！

 搜索出Lombok Plugin 旁边点Install就可以啦 ，我这里是安装好的。接下来就来使用lombok插件吧！在对象上加入@Data注解就可以啦。就自动帮我们把set、get、无参构造方法加进去了。

@Data
public class User {
    private int id;
    private String userName;
    private int age;
}

这里我们使用alibaba的fastJson来做json的转换，加入fastjson依赖

<!--fastJson-->
		<dependency>
			<groupId>com.alibaba</groupId>
			<artifactId>fastjson</artifactId>
			<version>1.2.47</version>
		</dependency>

接下来我们编写一个测试类：

@RunWith(SpringRunner.class)
@SpringBootTest
public class RedisTest {
    @Autowired
    private RedisService redisService;
    @Autowired
    private StringRedisTemplate stringRedisTemplate;

    @Test
    public void setUser() {
        User user = new User();
        user.setId(1);
        user.setAge(15);
        user.setUserName("张三");
        System.out.println(redisService.set("user", user));
        User userR = (User) redisService.get("user");
        System.out.println(userR);

       stringRedisTemplate.opsForValue().set("user1", JSON.toJSONString(user));
        User user1= JSONObject.toJavaObject(JSON.parseObject(stringRedisTemplate.opsForValue().get("user1")),User.class);

        System.out.println("user1:"+user1);
    }

}
