补充@Cacheable 标签进行批量获取对象.使用了redis的原子命令 mget 和 mset 来实现
<dependency>
<groupId>com.popa.cache</groupId>
<artifactId>redis-cache-popa</artifactId>
<version>1.0.0</version>
</dependency>
注意和@Cacheable依赖的redisTemplate保持一致:
注意和RedisCacheConfiguration的computePrefixWith保持一致:
@Bean
public MultiCacheConfig initMultiCacheConfig() {
return new MultiCacheConfig() {
@Override
public RedisTemplate<String, ?> getRedisTemplate() {
return redisTemplate;
}
@Override
public String cachePrefix() {
return "xxxx";
}
};
}扫描依赖包
@ComponentScan(basePackages = {"org.popa.cache.annotation" })@MultiCacheable 补充批量获取缓存
@Cacheable(value = "goods:view:spu", key = "#id", unless = "#result == null")
public GoodsSpu findById(Long id) {
return spuMapper.selectById(id);
}
/**
* 批量获取spu缓存
*
* @param ids
* @return
*/
@MultiCacheable(value = "goods:view:spu")
public Map<Long, GoodsSpu> findByIds(List<Long> ids) {
List<GoodsSpu> contents = spuMapper.selectBatchIds(ids);
return contents.stream().collect(Collectors.toMap(GoodsSpu::getId, Function.identity()));
}不足之处欢迎补充讨论
