how to intercept all requests in spring REST controllers?
提问by Alfredo M
I have a bunch of controllers like:
我有一堆控制器，例如：
@RestController
public class AreaController {
@RequestMapping(value = "/area", method = RequestMethod.GET)
public @ResponseBody ResponseEntity<Area> get(@RequestParam(value = "id", required = true) Serializable id) { ... }
}
and I need to intercept all the requests that reach them,
我需要拦截所有到达他们的请求，
I created an interceptor like this example:
我创建了一个像这个例子的拦截器：
http://www.mkyong.com/spring-mvc/spring-mvc-handler-interceptors-example/
http://www.mkyong.com/spring-mvc/spring-mvc-handler-interceptors-example/
but it never enters :(
但它永远不会进入:(
because I'm using only annotations, i don't have a XML to define the interceptor, what I've found its to set it like this:
因为我只使用注释，所以我没有一个 XML 来定义拦截器，我发现它是这样设置的：
@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.test.app")
public class AppConfig extends WebMvcConfigurerAdapter {
@Bean
public ControllerInterceptor getControllerInterceptor() {
ControllerInterceptor c = new ControllerInterceptor();
return c;
}
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(getControllerInterceptor());
super.addInterceptors(registry);
}
}
what am i doing wrong or am i missing something?
我做错了什么还是我错过了什么？
采纳答案by Alfredo M
so apparently i was doing something wrong but can't say what,
所以显然我做错了什么，但不能说是什么，
defining the interceptor like:
定义拦截器，如：
<mvc:interceptors>
<bean class="com.test.ControllerInterceptor" />
</mvc:interceptors>
I'm pretty sure that you can also define it in pure java, but this is working,
我很确定你也可以在纯 Java 中定义它，但这是有效的，

your Interceptorclass ControllerInterceptorisn't an application context managed bean. Make sure you put @Componentannotation on ControllerInterceptor and add it's package to @ComponentScan. So, let's say your ControllerInterceptorresides in package com.xyz.interceptors like:
您的Interceptor类ControllerInterceptor不是应用程序上下文管理的 bean。确保@Component在 ControllerInterceptor 上添加注释并将它的包添加到@ComponentScan. 因此，假设您ControllerInterceptor驻留在包 com.xyz.interceptors 中，例如：
package com.xyz.interceptors; //this is your package
@Component //put this annotation here
public class ControllerInterceptor extends HandlerInterceptorAdapter{
// code here
}
and your AppConfig becomes:
并且您的 AppConfig 变为：
@ComponentScan(basePackages = { "com.test.app", "com.xyz.interceptors" })
public class AppConfig extends WebMvcConfigurerAdapter {
// ...
}

Possible you are missing mapping
您可能缺少映射
registry.addInterceptor(getControllerInterceptor()).addPathPatterns("/**");
And as I know you don't have to use
据我所知，您不必使用
super.addInterceptors(registry);
