springboot2.0 使用攔截器后，導致靜態文件訪問不到的解決方案

package com.leenleda.ward.tv.admin.interceptor;

import com.leenleda.ward.tv.common.config.LeenledaConfig;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

import javax.annotation.Resource;
import java.util.Arrays;

@Configuration
@EnableWebMvc
public class CustomMVCConfiguration implements WebMvcConfigurer {

    @Resource
    LoginInterceptor loginInterceptor;

    @Autowired
    LeenledaConfig leenledaConfig;
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        //登錄攔截器
        registry.addInterceptor(loginInterceptor).addPathPatterns("/admin/**")
                .excludePathPatterns(Arrays.asList("/file/**"));
    }

    /**
     * 添加靜態資源文件，外部可以直接訪問地址
     * @param registry
     */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        String locationPath="file:"+leenledaConfig.getLeenledaUploadRoot()+"/leenleda/application/";
        registry.addResourceHandler("/file/**")
                .addResourceLocations(locationPath);
    }

}

其中file是自定義的虛擬路徑，訪問時過濾掉攔截，addResourceLocations 要訪問的文件路徑。
