java - Spring 5缓存不适用于@Cachable(CacheInterceptor不在调用堆栈中)？

Question

我通过添加 @Cachable 注释来启用公共(public)方法的缓存，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AOP:

<aop:aspectj-autoproxy 
    proxy-target-class="true"/>

然后启用缓存:

<cache:annotation-driven 
    mode="aspectj"
    proxy-target-class="true"/>

但是，结果不会被缓存，并且当从系统的其他部分调用该方法时，就会调用该方法。

我在方法中放置了一个制动点并检查调用堆栈:堆栈中没有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.

在我的代码的某些部分，私有(private)方法将被缓存。所以我必须使用 AspectJ 进行加载时编织。

Answer 1

因为您使用的是aspectJ 缓存模式，所以您的类路径中需要spring-aspects.jar。目前尚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模式作为代理，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类，因为您正在使用 proxy-target-class="true"
