根据配置为服务中的特定方法启用/禁用缓存 [英] Enable/Disable Caching for specific methods in a service based on configuration

问题描述

我们正在使用 Spring 的缓存抽象为我们的服务添加缓存行为.

We are using Spring's Caching abstraction to add caching behaviour to our services.

默认情况下，@Enablecaching 注释要么启用/禁用整个服务的缓存.

By default, @Enablecaching annotation either enables/disables caching for entire service.

@Cacheable 注释已用于所有方法.

The @Cacheable annotation has been used on all methods.

但是，现在我们要为某些端点/方法启用缓存并禁用其他端点的缓存

But, now we want to enable caching for some endpoints/methods and disable caching for other endpoints

有没有办法通过删除服务中添加的注释来实现这一点，例如拦截器/过滤器否决基于配置的某些方法的缓存行为.

Is there a way to achieve that with removing the added annotations in the service something like an Interceptor/Filter vetoing the caching behaviour for certain methods based on configuration.

推荐答案

一个解决方法 您可以根据参数使您的方法成为缓存的条件.缓存注释通过条件参数支持此类功能，该参数采用评估为 true 或 false 的 SpEL 表达式.

One work around for this You can make your method conditional for cache on the base of parameter. The cache annotations support such functionality through the condition parameter which takes a SpEL expression that is evaluated to either true or false.

@Cacheable(cacheNames="book", condition="#cached == false")
public Book findBook(boolean cached)

如文档中所述.https://docs.spring.io/spring/docs/current/spring-framework-reference/html/cache.html
