问题描述
我正在使用Spring Data Rest和JPA进行项目，并且正在尝试配置HTTP拦截器.根据参考文档， 在 Spring Web MVC文档-处理程序映射拦截器，我创建了一个扩展HandlerInterceptorAdapter的组件，如下所示:
I am working on a project with Spring Data Rest and JPA and I am trying to configure an HTTP interceptor. As per the reference docs, available in Spring Web MVC Docs - Handler Mapping Interceptor, I created a component that extends HandlerInterceptorAdapter as follows:
@Component
public class DBEditorTenantInterceptor extends HandlerInterceptorAdapter {
Logger logger = LoggerFactory.getLogger(DBEditorTenantInterceptor.class);
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
throws Exception {
logger.debug("********** INTERCEPTION SUCCESSFUL **********");
return true;
}
}
然后，通过扩展WebMvcConfig来注册拦截器(如 Spring Web MVC文档-配置拦截器
And then, registered the interceptor by extending WebMvcConfig (as explained in Spring Web MVC Docs - Config Interceptors
@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {
@Autowired
DBEditorTenantInterceptor dbEditorTenantInterceptor;
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(dbEditorTenantInterceptor)
.addPathPatterns("/**");
}
}
当我向Spring Data REST未使用的任何URL(例如/helloworld)发出HTTP请求时，拦截器将按预期工作，如我所见，记录器输出
When I issue HTTP requests to any URL that is not used by Spring Data REST such as /helloworld the Interceptor works as expected, as I see the logger output
017-10-26 13:16:24.689 DEBUG 17012 --- [p-nio-80-exec-4] c.c.v.d.DBEditorTenantInterceptor : ********** INTERCEPTION SUCCESSFUL **********
但是，当Spring数据仓库使用URL时，不会调用我的拦截器.这适用于所有网址，例如/api/{模型中的现有实体}
However, when the URL is used by spring data rest, my interceptor is not called. This applies to all URLs like /api/{existing entity in model}
为什么没有为Spring Data Rest URL调用我的拦截器?我该怎么做才能使拦截器对所有请求起作用?
Why is my interceptor not called for Spring Data Rest URLs ? What can I do to make my interceptor work for all requests ?
非常感谢.
推荐答案
通过声明类型为MappedInterceptor的bean并将其注入到我的拦截器中-扩展了HandlerInterceptorAdapter，我的拦截器由Spring Data Rest拾取，现在可用于任何URL在应用程序上.
By declaring a bean of type MappedInterceptor and injecting it with my interceptor - which extends HandlerInterceptorAdapter, my interceptor was picked up by Spring Data Rest and now works for any URL on the application.
这转化为以下实现(代替了我原来的问题):
This translated to the following implementation (replacing the one in my original question):
@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {
@Autowired
DBEditorTenantInterceptor dbEditorTenantInterceptor;
@Bean
public MappedInterceptor dbEditorTenantInterceptor() {
return new MappedInterceptor(new String[]{"/**"}, dbEditorTenantInterceptor);
}
}
不幸的是，我在Spring文档中找不到对此的任何引用.
Unfortunately, I could not find any references to this on the Spring documentation.
