25     LoginInterceptor loginInterceptor;
26 
27     @Autowired
28     LeenledaConfig leenledaConfig;
29     @Override
30     public void addInterceptors(InterceptorRegistry registry) {
31         //登录拦截器
32         registry.addInterceptor(loginInterceptor).addPathPatterns("/admin/**")
33                 .excludePathPatterns(Arrays.asList("/file/**"));
34     }
35 
36     /**
37      * 添加静态资源文件，外部可以直接访问地址
38      * @param registry
39      */
40     @Override
41     public void addResourceHandlers(ResourceHandlerRegistry registry) {
42         String locationPath="file:"+leenledaConfig.getLeenledaUploadRoot()+"/leenleda/application/";
43         registry.addResourceHandler("/file/**")
44                 .addResourceLocations(locationPath);
45     }
46 
47 }

拦截器注册

其中file是自定义的虚拟路径，访问时过滤掉拦截，addResourceLocations 要访问的文件路径。
