将 @PostFilter 注释应用于通用 Spring Data Jpa 存储库方法 [英] Applying @PostFilter annotation to a generic Spring Data Jpa repository method

问题描述

我想在 Spring Data Jpa 存储库通用方法(例如 findAll)上使用 @PostFilter 注释，如下所示:

I want to use the @PostFilter annotation on a Spring Data Jpa repository generic method (such as a findAll) as follows:

@PostFilter("filterObject.isActivated()==true")
public List<Advertisement> findAll();

记住这些方法是由 Spring Data Jpa自动"提供的，因此不会在应用程序代码中公开，我该如何做到这一点?

How can I do that bearing in mind the those methods are provided "automagically" by Spring Data Jpa and are therefore not exposed in the application code?

推荐答案

是的，您可以向 Spring Data Repository 提供的任何方法添加 @PostFilter.只需覆盖现有方法 findAll() 并添加您的 @PostFilter 注释，如您的示例所示.不要忘记在定义存储库的配置中添加

Yes, you can add a @PostFilter to any method provided by a Spring Data Repository. Just override existing method findAll() and add your @PostFilter annotation as depicted in your example. Don't forget to add to your configuration where your repositories are defined

<global-method-security pre-post-annotations="enabled" />

或在基于 Java 的配置中

or in a java based configuration

@EnableGlobalMethodSecurity(prePostEnabled = true)

分别.记住.这仅适用于集合和数组.对于每个其他返回类型，如 页面 你得到一个 IllegalArgumentException.见 DefaultMethodSecurityExpressionHandler#filter 实现细节.

respectively. Keep in mind. This works just for collections and arrays. For every other return type like Page you get an IllegalArgumentException. See DefaultMethodSecurityExpressionHandler#filter for implementation details.
