Spring MVC-拦截器从未调用 [英] Spring MVC - Interceptor never called

问题描述

我正在尝试在应用程序中配置拦截器，但无法使其正常工作.

I am trying to configure an interceptor in my application and I am not being able to make it work.

在我的应用程序配置类中，我以以下方式配置:

In my application configuration class, I have configured in the following way:

@Configuration
@EnableWebMvc
public class AppContextConfiguration extends WebMvcConfigurerAdapter {
    ...
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new MyInterceptor());
    }
    ...
}

拦截器:

public class MyInterceptor extends HandlerInterceptorAdapter{

    private static final Logger logger = LoggerFactory.getLogger(MyInterceptor.class);

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, 
        Object handler) throws Exception {

        logger.debug("MyInterceptor - PREHANDLE");
    }
}

有人知道为什么不被调用吗?

Does anybody know why is not being invoked?

推荐答案

我正在使用Spring Boot，并且遇到相同的问题，即调用addInterceptors()来注册拦截器，但是该拦截器在请求期间从未触发过.但是XML配置没有问题.

I'm using Spring Boot and was having the same problem where addInterceptors() was being called to register the interceptor, but the interceptor never fired during a request. Yet XML configuration worked no problem.

基本上，您不需要WebMvcConfigurerAdapter类.您只需要声明MappedInterceptor类型的@Bean:

Basically, you don't need the WebMvcConfigurerAdapter class. You just need to declare an @Bean of type MappedInterceptor:

@Bean
public MappedInterceptor myInterceptor()
{
    return new MappedInterceptor(null, new MyInterceptor());
}
