spring boot 2.x静态资源会被拦截器拦截的原因和解决方法：

不要继承 WebMvcConfigurationSupport
实现 WebMvcConfigurer 接口
WebMvcConfigurationSupport的内置方法和WebMvcConfigurer里的都一样

第一种：


    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/static/**").addResourceLocations("classpath:/static/");
    }

第二种比较全面一点：


  private static final String[] CLASSPATH_RESOURCE_LOCATIONS = {
            "classpath:/META-INF/resources/", "classpath:/resources/",
            "classpath:/static/", "classpath:/public/" };


    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        if (!registry.hasMappingForPattern("/webjars/**")) {
            registry.addResourceHandler("/webjars/**").addResourceLocations(
                    "classpath:/META-INF/resources/webjars/");
        }
        if (!registry.hasMappingForPattern("/**")) {
            registry.addResourceHandler("/**").addResourceLocations(
                    CLASSPATH_RESOURCE_LOCATIONS);
        }

    }
