近來為了項目的接口文檔，而集成了swagger2，但是集成完畢后，訪問swagger-ui.html卻報404，檢查后發(fā)現(xiàn)，原來是被攔截了。下面寫一下我的解決方法。
首先新建 WebConfig類實現(xiàn)WebMvcConfigurer接口，WebMvcConfigurer接口實際上就是springBoot做攔擊的一個抽象的接口，在springBoot早期的版本，使用的是WebMvcConfigurerAdapter抽象父類進行管理權(quán)限。
在WebConfig類重寫addResourceHandlers方法，將不攔截的路徑放入。

@Configuration
public class WebConfig implements WebMvcConfigurer {
    @Override
    public void configurePathMatch(PathMatchConfigurer pathMatchConfigurer) {

    }

    @Override
    public void configureContentNegotiation(ContentNegotiationConfigurer contentNegotiationConfigurer) {

    }

    @Override
    public void configureAsyncSupport(AsyncSupportConfigurer asyncSupportConfigurer) {

    }

    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer defaultServletHandlerConfigurer) {

    }

    @Override
    public void addFormatters(FormatterRegistry formatterRegistry) {

    }

    @Override
    public void addInterceptors(InterceptorRegistry interceptorRegistry) {

    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/statics/**").addResourceLocations("classpath:/statics/");
        // 解決 SWAGGER 404報錯
        registry.addResourceHandler("/swagger-ui.html").addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
    }

    @Override
    public void addCorsMappings(CorsRegistry corsRegistry) {

    }

    @Override
    public void addViewControllers(ViewControllerRegistry viewControllerRegistry) {

    }

    @Override
    public void configureViewResolvers(ViewResolverRegistry viewResolverRegistry) {

    }

    @Override
    public void addArgumentResolvers(List<HandlerMethodArgumentResolver> list) {

    }

    @Override
    public void addReturnValueHandlers(List<HandlerMethodReturnValueHandler> list) {

    }

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> list) {

    }

    @Override
    public void extendMessageConverters(List<HttpMessageConverter<?>> converters) {

    }

    @Override
    public void configureHandlerExceptionResolvers(List<HandlerExceptionResolver> list) {

    }

    @Override
    public void extendHandlerExceptionResolvers(List<HandlerExceptionResolver> list) {

    }

    @Override
    public Validator getValidator() {
        return null;
    }

    @Override
    public MessageCodesResolver getMessageCodesResolver() {
        return null;
    }
}

這樣就解決了無法訪問swagger-ui的問題了。
