Spring 5 缓存不适用于@Cachable(CacheInterceptor 不在调用堆栈中)?
Spring 5 cache not work for @Cachable (CacheInterceptor is not in call stack)?
我通过添加 @Cachable 注释为 public 方法启用缓存,如下所示:
@Cacheable(cacheNames = "saas_setting", //
key = "#key")
public Setting get(String key) { ... }
另一方面,我添加了 cacheManager bean:
<bean id="cacheManager"
class="org.springframework.cache.support.SimpleCacheManager">
<property name="caches">
<set>
<bean
class="org.springframework.cache.concurrent.ConcurrentMapCacheFactoryBean"
name="saas_setting" />
</set>
</property>
</bean>
我启用了 AOP:
<aop:aspectj-autoproxy
proxy-target-class="true"/>
然后启用缓存:
<cache:annotation-driven
mode="aspectj"
proxy-target-class="true"/>
然而,结果不会被缓存,当从系统的其他部分调用时会调用该方法。
我在方法里放了一个刹车点,查看调用栈:栈里没有CachInterceptor?!

基于 Spring 文档:
The default advice mode for processing caching annotations is "proxy" which allows for interception of calls through the proxy only; local calls within the same class cannot get intercepted that way. For a more advanced mode of interception, consider switching to "aspectj" mode in combination with compile-time or load-time weaving.
在我的某些代码中,私有方法将被缓存。所以我必须将 AspectJ 与加载时编织一起使用。
因为您正在使用缓存的 aspectJ 模式,所以您的 class 路径中需要 spring-aspects.jar。不清楚为什么要使用 aspectj 代理而不是默认代理。
由于您使用 aspectj 模式进行代理,因此您还需要设置加载时编织。
可以使用以下方式启用加载时间编织:
<context:load-time-weaver/>
此外,您使用的方法必须来自具体 class,因为您正在使用 proxy-target-class="true"
