@Cacheable

添加依赖

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

1.注解不生效

@Cacheable(value = "listDetail", key = "#cycleId + '_' + #kepointId")

在需要缓存的类或方法上添加注解@Cacheable，然后在启动类上添加@EnableCaching开启缓存。

2.Cannot find cache named 'XXX' for Builder

    @Bean
    public CacheManager cacheManager(RedisConnectionFactory factory) {
        RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig()
                .entryTtl(Duration.ofSeconds(60))
                .disableCachingNullValues();
 
        return RedisCacheManager.builder(factory)
                .cacheDefaults(config)
                .transactionAware()
                .build();
    }

 3,SpringBoot2.0之后将Redis的默认客户端由Jedis更换为lettuce
