• 配置路径映射

  	@Resource
      private AuthenticationInterceptor authenticationInterceptor;
  
  	@Override
  	public void addInterceptors(InterceptorRegistry registry) {
      	//注册拦截器要声明拦截器对象和要拦截的请求
      	log.info("开始注册拦截器要声明拦截器对象和要拦截的请求");
      	registry.addInterceptor(authenticationInterceptor)
              .addPathPatterns("/**")
              .excludePathPatterns("/loginIn", "/getVerificationCode","/template/getTemplate","/log/getSysMessage")
              //附件获取免鉴权
              .excludePathPatterns("/attachment/**")
              //加载有匿名注解的请求
              .excludePathPatterns(apiInterceptorAspect.getAnonApiAuthenticateList());
      }
  	
      @Override
      public void addResourceHandlers(ResourceHandlerRegistry registry) {
          //需要的文件路径映射
      	registry.addResourceHandler("/attachment/**").addResourceLocations("file:F:/data/attachments/");
          //项目内静态文件映射，仍然可以访问到静态资源
          registry.addResourceHandler("/**").addResourceLocations("classpath:/static/");
         	super.addResourceHandlers(registry);
      }
