@Cacheable key是两个字符串

@Cacheable注解是Spring框架中用于缓存方法结果的注解。根据引用[2]中的描述，当有两个入参，并且我们希望以这两个参数同时作为缓存的key区分时，可以使用如下方式设置@Cacheable注解的key属性：

@Cacheable(cacheNames = "cacheName", key = "#param1 + '_' + #param2")

其中，`param1`和`param2`分别代表方法的两个参数。通过在key属性中使用`+`来拼接两个参数的值，以生成唯一的缓存key。这样就可以实现根据两个字符串参数来区分缓存了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
