关于 Redis 集群的搭建可以参考我的另一篇博客：  
[Redis 集群模式详解 - 主从(master-slave)、哨兵(sentinel)、集群(cluster)][Redis _ - _master-slave_sentinel_cluster]

#### Spring Boot 2.0 整合 Redis ####

下面开始 Spring Boot 2.0 整合 Redis，Spring boot 中整合 Redis 非常简单，在 pom.xml中添加依赖：

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

Spring boot 2.0 的 spring-boot-starter-data-redis 中，默认使用的是 Lettuce 作为 Redis 客户端，它与 Jedis 的主要区别如下：

*  Jedis 是同步的，不支持异步，Jedis 客户端实例不是线程安全的，需要每个线程一个 Jedis 实例，所以一般通过连接池来使用 Jedis
 *  Lettuce 是基于 Netty 框架的事件驱动的 Redis 客户端，其方法调用是异步的，Lettuce 的 API 也是线程安全的，所以多个线程可以操作单个 Lettuce 连接来完成各种操作，同时 Lettuce 也支持连接池

如果不使用默认的 Lettuce，使用 Jedis 的话，可以排除 Lettuce 的依赖，手动加入 Jedis 依赖，如下：

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>io.lettuce</groupId>
                    <artifactId>lettuce-core</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
    
        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>3.4.1</version>
        </dependency>

在配置文件 application.yml 中添加配置（针对单实例）

spring:
      redis:
        host: 192.168.1.30
        port: 6379
        password: 123456
        database: 1 # 数据库索引，默认0
        timeout: 6000 # 连接超时，单位ms
        jedis:  # 或lettuce, 连接池配置，springboot 2.0 中使用 jedis 或者 lettuce 配置连接池，默认为 lettuce 连接池
          pool:
            max-active: 8 # 连接池最大连接数（使用负值表示没有限制）
            max-wait: -1 # 连接池分配连接最大阻塞等待时间（阻塞时间到，抛出异常。使用负值表示无限期阻塞）
            max-idle: 8 # 连接池中的最大空闲连接数
            min-idle: 0 # 连接池中的最小空闲连接数

添加配置类 RedisConfig，其中 @EnableCaching 注解是为了使 @Cacheable、@CacheEvict、@CachePut、@Caching 注解生效

import com.fasterxml.jackson.annotation.JsonAutoDetect;
    import com.fasterxml.jackson.annotation.PropertyAccessor;
    import com.fasterxml.jackson.databind.ObjectMapper;
    import org.springframework.cache.annotation.EnableCaching;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.data.redis.connection.RedisConnectionFactory;
    import org.springframework.data.redis.core.RedisTemplate;
    import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
    import org.springframework.data.redis.serializer.RedisSerializer;
    import org.springframework.data.redis.serializer.StringRedisSerializer;
    
    @Configuration
    @EnableCaching
    public class RedisConfig { 
    
        /** * redis重写RedisTemplate. */
        @Bean
        public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) { 
            RedisTemplate<String, Object> redisTemplate = new RedisTemplate();
            redisTemplate.setConnectionFactory(redisConnectionFactory);
    
            Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
            ObjectMapper om = new ObjectMapper();
            om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
            //序列化时允许非常量字段均输出类型，即redis序列化后带有类型
            om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
            jackson2JsonRedisSerializer.setObjectMapper(om);
    
            RedisSerializer<String> stringSerializer = new StringRedisSerializer();
    
            // key 采用 String 的序列化方式
            redisTemplate.setKeySerializer(stringSerializer);
            // hash 的 key 也采用 String 的序列化方式
            redisTemplate.setHashKeySerializer(stringSerializer);
            // value 序列化方式采用 jackson
            redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
            // hash 的 value 序列化方式采用 jackson
            redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
            redisTemplate.afterPropertiesSet();
            return redisTemplate;
        }
    }

上述配置类注入了自定义的 RedisTemplate<String, Object>， 替换 RedisAutoConfiguration 中自动配置的 RedisTemplate<Object, Object> 类（RedisAutoConfiguration 另外还自动配置了 StringRedisTemplate）。

此时，我们可以通过定义一个基于 RedisTemplate 的工具类，或通过在 Service 层添加 @Cacheable、@CacheEvict、@CachePut、@Caching 注解来使用缓存。比如定义一个 RedisService 类，封装常用的 Redis 操作方法：

import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.data.redis.core.RedisTemplate;
    import org.springframework.data.redis.core.StringRedisTemplate;
    import org.springframework.stereotype.Component;
    import org.springframework.util.CollectionUtils;
    
    import java.util.Objects;
    import java.util.Properties;
    import java.util.concurrent.TimeUnit;
    
    @Component
    public class RedisService { 
    
        private static final Logger LOGGER = LoggerFactory.getLogger(RedisService.class);
    
        private RedisTemplate<String, Object> redisTemplate;
    
        private StringRedisTemplate stringRedisTemplate;
    
    
        public RedisService(RedisTemplate<String, Object> redisTemplate,
                         StringRedisTemplate stringRedisTemplate) { 
            this.redisTemplate = redisTemplate;
            this.stringRedisTemplate = stringRedisTemplate;
        }
    
        /** * 普通缓存放入 * * @param key 键 * @param value 值 * @return */
        public void set(String key, Object value) { 
            try { 
                redisTemplate.opsForValue().set(key, value);
            } catch (Exception e) { 
                LOGGER.error("exception when set key {}. ", key, e);
            }
        }
    
        /** * 普通缓存放入并设置时间 * * @param key 键 * @param value 值 * @param time 时间(秒) time要大于0 如果time小于等于0 将设置无限期 * @return */
        public void set(String key, Object value, long time) { 
            try { 
                if (time > 0) { 
                    redisTemplate.opsForValue().set(key, value, time, TimeUnit.SECONDS);
                } else { 
                    this.set(key, value);
                }
            } catch (Exception e) { 
                LOGGER.error("exception when set key {}. ", key, e);
            }
        }
    
        /** * 指定缓存失效时间 * * @param key 键 * @param time 时间(秒) * @return */
        public void expire(String key, long time) { 
            try { 
                if (time > 0) { 
                    redisTemplate.expire(key, time, TimeUnit.SECONDS);
                }
            } catch (Exception e) { 
                LOGGER.error("exception when expire key {}. ", key, e);
            }
        }
    
        /** * 根据key获取过期时间 * * @param key 键 不能为null * @return 时间(秒) 返回0代表为永久有效 */
        public long getExpire(String key) { 
            return redisTemplate.getExpire(key, TimeUnit.SECONDS);
        }
    
        /** * 判断key是否存在 * * @param key 键 * @return true 存在 false不存在 */
        public boolean hasKey(String key) { 
            try { 
                return redisTemplate.hasKey(key);
            } catch (Exception e) { 
                LOGGER.error("exception when check key {}. ", key, e);
                return false;
            }
        }
    
        /** * 删除缓存 * * @param key 可以传一个值 或多个 */
        @SuppressWarnings("unchecked")
        public void del(String... key) { 
            if (Objects.nonNull(key) && key.length > 0) { 
                if (key.length == 1) { 
                    redisTemplate.delete(key[0]);
                } else { 
                    redisTemplate.delete(CollectionUtils.arrayToList(key));
                }
            }
        }
    
        /** * 普通缓存获取 * * @param key 键 * @return 值 */
        public Object get(String key) { 
            return Objects.isNull(key) ? null : redisTemplate.opsForValue().get(key);
        }
    
        /** * 递增 * * @param key 键 * @param delta 要增加几(大于0) * @return */
        public long incr(String key, long delta) { 
            if (delta <= 0) { 
                throw new RuntimeException("递增因子必须大于0");
            }
            return redisTemplate.opsForValue().increment(key, delta);
        }
    
        /** * 递减 * * @param key 键 * @param delta 要减少几(小于0) * @return */
        public long decr(String key, long delta) { 
            if (delta <= 0) { 
                throw new RuntimeException("递减因子必须大于0");
            }
            return redisTemplate.opsForValue().increment(key, -delta);
        }
    
        /** * 获取 Redis 服务器信息 * * @param type 要获取的属性类型 * @return 属性信息 */
        public Properties getRedisInfo(String type) { 
            return Objects.isNull(type) ? stringRedisTemplate.getRequiredConnectionFactory().getConnection().info()
                    : stringRedisTemplate.getRequiredConnectionFactory().getConnection().info(type);
        }
    }

在 ServiceImpl 下使用参考如下：

@Service
    @CacheConfig(cacheNames = "users")
    public class UserService { 
    
        private static Map<String, User> userMap = new HashMap<>();
    
        @CachePut(key = "#user.username")
        public User addUser(User user){ 
            user.setUid(UUID.randomUUID().toString());
            System.out.println("add user: " + user);
            userMap.put(user.getUsername(), user);
            return user;
        }
    
        @Caching(put = { 
                @CachePut( key = "#user.username"),
                @CachePut( key = "#user.uid")
        })
        public User addUser2(User user) { 
            user.setUid(UUID.randomUUID().toString());
            System.out.println("add user2: " + user);
            userMap.put(user.getUsername(), user);
            return user;
        }
        ...
    }

#### Spring Boot 2.0 整合 Redis Sentinel（哨兵）模式 ####

Spring Boot 2.0 整合 Redis 哨兵模式除了配置稍有差异，其它与整合单实例模式类似，配置参考如下：

spring:
      redis:
        sentinel:
          master: mymaster
          nodes: 192.168.1.29:26379,192.168.1.30:26379,192.168.1.31:26379 # 哨兵的 IP:Port 列表
        password: 123456
        database: 1 # 数据库索引，默认0
        timeout: 6000 # 连接超时，单位ms
        jedis: # 或lettuce, 连接池配置，springboot 2.0 中使用 jedis 或者 lettuce 配置连接池，默认为 lettuce 连接池
          pool:
            max-active: 8 # 连接池最大连接数（使用负值表示没有限制）
            max-wait: -1 # 连接池分配连接最大阻塞等待时间（阻塞时间到，抛出异常。使用负值表示无限期阻塞）
            max-idle: 8 # 连接池中的最大空闲连接数
            min-idle: 0 # 连接池中的最小空闲连接数

#### Spring Boot 2.0 整合 Redis Cluster 模式 ####

Spring Boot 2.0 整合 Redis 哨兵模式除了配置稍有差异，其它与整合单实例模式也类似，配置参考如下：

spring:
      redis:
        cluster:
          nodes: 192.168.1.29:7001, 192.168.1.29:7002, 192.168.1.30:7003, 192.168.1.30:7004, 192.168.1.31:7005, 192.168.1.31:7006
        password: 123456
        database: 1 # 数据库索引，默认0
        timeout: 6000 # 连接超时，单位ms
        jedis: # 或lettuce, 连接池配置，springboot 2.0 中使用 jedis 或者 lettuce 配置连接池，默认为 lettuce 连接池
          pool:
            max-active: 8 # 连接池最大连接数（使用负值表示没有限制）
            max-wait: -1 # 连接池分配连接最大阻塞等待时间（阻塞时间到，抛出异常。使用负值表示无限期阻塞）
            max-idle: 8 # 连接池中的最大空闲连接数
            min-idle: 0 # 连接池中的最小空闲连接数

#### Unit 测试 ####

@RunWith(SpringRunner.class)
    @SpringBootTest
    public class JedisPoolTest { 
    
        private static final Logger LOGGER = LoggerFactory.getLogger(JedisPoolTest.class);
    
        @Autowired
        private RedisService redisService;
    
        @Test
        public void redisTest() { 
            redisService.set("k111", "v111.sanchar");
            String v1 = Objects.isNull(redisService.get("k111")) ? "" : redisService.get("k111").toString();
            LOGGER.info("value: {}", v1);
    
            boolean isKeyExist = redisService.hasKey("k111");
            LOGGER.info("key exist: {}", isKeyExist);
    
            redisService.del("k111");
            String v2 = Objects.isNull(redisService.get("k111")) ? "" : redisService.get("k111").toString();
            LOGGER.info("value: {}", v2);
    
            Properties replication = redisService.getRedisInfo("replication");
            LOGGER.info("replication info: {}", replication);
    
            Properties redisInfo = redisService.getRedisInfo(null);
            LOGGER.info("redis Info: {}", redisInfo);
        }
    }
