springboot 用了@ImportResource 配置的拦截器就不起作用了

springboot 用了@ImportResource 配置的拦截器就不起作用了

去掉@ImportResource注解 拦截器就好了

代码：

package com.example.springbootdemo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;

@SpringBootApplication
@ImportResource(locations={"classpath:config/spring-mongo.xml"})
public class SpringbootdemoApplication extends SpringBootServletInitializer {

   /**
    * 让spring boot在tomcat中运行
    * @param builder
    * @return
    */
   @Override
   protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
      return builder.sources(SpringbootdemoApplication.class);
   }
   public static void main(String[] args) {
      SpringApplication.run(SpringbootdemoApplication.class, args);
   }
}

拦截器继承WebMvcConfigurerAdapter：

package com.example.springbootdemo.Interceptor;

import com.example.springbootdemo.Interceptor.LoginInterceptor;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;


@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {

    /**
     * 自定义静态资源
     * @param registry
     */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        //将所有/static/** 访问都映射到classpath:/static/ 目录下
        registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/");
    }
    /**
     * 拦截器(用户登录验证)
     * @param registry
     */
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        // addPathPatterns 用于添加拦截规则
        // excludePathPatterns 用户排除拦截
        registry.addInterceptor(new LoginInterceptor()).addPathPatterns("/**").excludePathPatterns("/user","/login");
        super.addInterceptors(registry);
    }
}

拦截方法：

package com.example.springbootdemo.Interceptor;


import org.springframework.stereotype.Component;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class LoginInterceptor implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        boolean flag =true;
       /* User user=(User)request.getSession().getAttribute("user");
        if(null==user){
            response.sendRedirect("toLogin");
            flag = false;
        }else{
            flag = true;
        }*/
       System.out.print("进来了");
        return flag;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
    }
}

求解 @ImportResource注解怎么会影响拦截器！！！！！
