因为各种场合比如门户和后台，需要不同的redis配置，我们在common包配置通用的reids配置。

1.新建service目录，建立RedisService服务接口，同时编写工具类实现该接口。

public interface RedisService {/*** 保存属性*/void set(String key, Object value, long time);/*** 保存属性*/void set(String key, Object value);/*** 获取属性*/Object get(String key);/*** 删除属性*/Boolean del(String key);/*** 批量删除属性*/Long del(List<String> keys);/*** 设置过期时间*/Boolean expire(String key, long time);/*** 获取过期时间*/Long getExpire(String key);/*** 判断是否有该属性*/Boolean hasKey(String key);/*** 按delta递增*/Long incr(String key, long delta);/*** 按delta递减*/Long decr(String key, long delta);/*** 获取Hash结构中的属性*/Object hGet(String key, String hashKey);/*** 向Hash结构中放入一个属性*/Boolean hSet(String key, String hashKey, Object value, long time);/*** 向Hash结构中放入一个属性*/void hSet(String key, String hashKey, Object value);/*** 直接获取整个Hash结构*/Map<Object, Object> hGetAll(String key);/*** 直接设置整个Hash结构*/Boolean hSetAll(String key, Map<String, Object> map, long time);/*** 直接设置整个Hash结构*/void hSetAll(String key, Map<String, ?> map);/*** 删除Hash结构中的属性*/void hDel(String key, Object... hashKey);/*** 判断Hash结构中是否有该属性*/Boolean hHasKey(String key, String hashKey);/*** Hash结构中属性递增*/Long hIncr(String key, String hashKey, Long delta);/*** Hash结构中属性递减*/Long hDecr(String key, String hashKey, Long delta);/*** 获取Set结构*/Set<Object> sMembers(String key);/*** 向Set结构中添加属性*/Long sAdd(String key, Object... values);/*** 向Set结构中添加属性*/Long sAdd(String key, long time, Object... values);/*** 是否为Set中的属性*/Boolean sIsMember(String key, Object value);/*** 获取Set结构的长度*/Long sSize(String key);/*** 删除Set结构中的属性*/Long sRemove(String key, Object... values);/*** 获取List结构中的属性*/List<Object> lRange(String key, long start, long end);/*** 获取List结构的长度*/Long lSize(String key);/*** 根据索引获取List中的属性*/Object lIndex(String key, long index);/*** 向List结构中添加属性*/Long lPush(String key, Object value);/*** 向List结构中添加属性*/Long lPush(String key, Object value, long time);/*** 向List结构中批量添加属性*/Long lPushAll(String key, Object... values);/*** 向List结构中批量添加属性*/Long lPushAll(String key, Long time, Object... values);/*** 从List结构中移除属性*/Long lRemove(String key, long count, Object value);
}

2.在config目录下，编写redis通用配置

public class BaseRedisConfig {@Beanpublic RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {RedisSerializer<Object> serializer = redisSerializer();RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();redisTemplate.setConnectionFactory(redisConnectionFactory);redisTemplate.setKeySerializer(new StringRedisSerializer());redisTemplate.setValueSerializer(serializer);redisTemplate.setHashKeySerializer(new StringRedisSerializer());redisTemplate.setHashValueSerializer(serializer);redisTemplate.afterPropertiesSet();return redisTemplate;}@Beanpublic RedisSerializer<Object> redisSerializer() {//创建JSON序列化器Jackson2JsonRedisSerializer<Object> serializer = new Jackson2JsonRedisSerializer<>(Object.class);ObjectMapper objectMapper = new ObjectMapper();objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);//必须设置，否则无法将JSON转化为对象，会转化成Map类型objectMapper.activateDefaultTyping(LaissezFaireSubTypeValidator.instance,ObjectMapper.DefaultTyping.NON_FINAL);serializer.setObjectMapper(objectMapper);return serializer;}@Beanpublic RedisCacheManager redisCacheManager(RedisConnectionFactory redisConnectionFactory) {RedisCacheWriter redisCacheWriter = RedisCacheWriter.nonLockingRedisCacheWriter(redisConnectionFactory);//设置Redis缓存有效期为1天RedisCacheConfiguration redisCacheConfiguration = RedisCacheConfiguration.defaultCacheConfig().serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(redisSerializer())).entryTtl(Duration.ofDays(1));return new RedisCacheManager(redisCacheWriter, redisCacheConfiguration);}@Beanpublic RedisService redisService(){return new RedisServiceImpl();}}

3.其他包只需要继承该基础配置就够了

@EnableCaching
@Configuration
public class RedisConfig extends BaseRedisConfig {
}
