Springboot 2.0.x 集成Redis缓存

---

1、引入Redis缓存依赖

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

2、配置Redis 数据库

spring:
    redis:
      host: localhost
      database: 0
      port: 6379
      jedis:
        pool:
          max-active: 8
          max-idle: 8
          min-idle: 0
          max-wait: -1ms
      password:
      ssl: false

3、配置Redis CacheManager

@Component
public class CacheConfig {
    @Bean
    CacheManager cacheManager(RedisConnectionFactory redisConnectionFactory) {
        RedisCacheConfiguration redisCacheConfiguration = RedisCacheConfiguration.defaultCacheConfig()
                // 设置缓存有效期20分钟
                .entryTtl(Duration.ofMinutes(20));


        return RedisCacheManager
                .builder(RedisCacheWriter.nonLockingRedisCacheWriter(redisConnectionFactory))
                .cacheDefaults(redisCacheConfiguration).build();
    }
}

4、开启缓存

@EnableCaching

5、使用缓存

// value 可以随便写什么值，根据需要而定
// key生成策略可以根据需求来定，如果是常规全局缓存，可以写一个可识别的固定值
@Cacheable(value = CacheConfig.COMMON,key = "'DBEC90C227604576B66E8BA64C09A0D9'")
