Spring HandlerInterceptor mapping with annotations
提问by user2160696
Good day. I got a spring mvc application and 2 controllers inside. First controller (PublicController) can process requests from all users, Second (PrivateController) can only process authorized users.
再会。我有一个 spring mvc 应用程序和 2 个控制器。第一个控制器（PublicController）可以处理所有用户的请求，第二个（PrivateController）只能处理授权用户。
So I implemented two Handler Interceptor`s
所以我实现了两个Handler拦截器
@Configuration
@EnableWebMvc
@ComponentScan(basePackages="webapp.base.package")
public class WebApplicationConfig extends WebMvcConfigurerAdapter {
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new LoggerInterceptor());
registry.addInterceptor(new AccessInterceptor());
}
}
I need my LoggerInterceptorto handle all controller's requests, and my AccessInterceptorto handle only PrivateController's requests.
I must map Interceptorsto Controllerswith annotations
我需要LoggerInterceptor处理所有控制器的请求，而我AccessInterceptor只需要处理PrivateController的请求。我必须用注释映射Interceptors到Controllers

Just solve it.
就解决吧。
@Configuration
@EnableWebMvc
@ComponentScan(basePackages="webapp.base.package")
public class WebApplicationConfig extends WebMvcConfigurerAdapter {
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new LoggerInterceptor()).addPathPatterns("/**");;
registry.addInterceptor(new AccessInterceptor()).addPathPatterns("/private/**");;
}
}

I don't know why, when I use your way, it worked. But the interceptor executed twice. And I found another way to do this.
我不知道为什么，当我用你的方式时，它奏效了。但是拦截器执行了两次。我找到了另一种方法来做到这一点。
@Bean
public MappedInterceptor interceptor() {
return new MappedInterceptor(null, new String[]{"/","/**/*.js", "/**/*.html", "/**/*.css"}, new LogInterceptor());
}
