java – Spring boot:如何在静态资源中添加拦截器?

我在/ static / img / **中有几个文件夹,我需要在其中一些文件夹中添加拦截器来检查用户权限.我之前使用过拦截器并以这种方式添加它们:

@SpringBootApplication
@EnableTransactionManagement
public class Application extends WebMvcConfigurerAdapter {

  ...

  @Override
  public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry
      .addResourceHandler("/static/**")
      .addResourceLocations("classpath:/static/");
  }

  @Bean
  public AuthHeaderInterceptor authHeaderInterceptor() {
    return new AuthHeaderInterceptor();
  }

  @Bean
  public AuthCookieInterceptor authCookieInterceptor() {
    return new AuthCookieInterceptor();
  }

  @Override
  public void addInterceptors(InterceptorRegistry registry) {
    registry
      .addInterceptor(authHeaderInterceptor())
      .addPathPatterns(REST_URL)
      .excludePathPatterns(
        new String[] {
          REST_SECURITY_URL,
          REST_SETTINGS_URL,
          REST_REPORTS_URL
        }
      );

    registry
      .addInterceptor(authCookieInterceptor())
      .addPathPatterns(REST_REPORTS_URL);
  }
}

一切都适用于休息控制器及其URL,但现在我需要保护一些静态资源,我添加了这个:

@SpringBootApplication
@EnableTransactionManagement
public class Application extends WebMvcConfigurerAdapter {

  ...

  @Bean 
  public RoleAdminInterceptor roleAdminInterceptor() {
    return new RoleAdminInterceptor();
  }

  @Override
  public void addInterceptors(InterceptorRegistry registry) {
    registry
      .addInterceptor(authHeaderInterceptor())
      .addPathPatterns(REST_URL)
      .excludePathPatterns(
        new String[] {
          REST_SECURITY_URL,
          REST_SETTINGS_URL,
          REST_REPORTS_URL
        }
      );

    //THIS NOT WORK
    registry
      .addInterceptor(roleAdminInterceptor())
      .addPathPatterns("/static/img/admin/**");

    registry
      .addInterceptor(authCookieInterceptor())
      .addPathPatterns(REST_REPORTS_URL);
  }
}

注释行不起作用.当我向/static/img/admin/test.png发送请求时,从不调用RoleAdminInterceptor.

我做错了什么?

我认为在这种情况下你可以使用带有Spring安全性的过滤器而不是拦截器,因为你可以在点击拦截器之前验证进程早期的访问,除非你有一个特定的用例需要在这里使用拦截器.
