近来为了项目的接口文档，而集成了swagger2，但是集成完毕后，访问swagger-ui.html却报404，检查后发现，原来是被拦截了。下面写一下我的解决方法。

首先新建 WebConfig类实现WebMvcConfigurer接口，WebMvcConfigurer接口实际上就是springBoot做拦击的一个抽象的接口，在springBoot早期的版本，使用的是WebMvcConfigurerAdapter抽象父类进行管理权限。

在WebConfig类重写addResourceHandlers方法，将不拦截的路径放入。

@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/");

// 解决 SWAGGER 404报错

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 list) {

}

@Override

public void addReturnValueHandlers(List list) {

}

@Override

public void configureMessageConverters(List> list) {

}

@Override

public void extendMessageConverters(List> converters) {

}

@Override

public void configureHandlerExceptionResolvers(List list) {

}

@Override

public void extendHandlerExceptionResolvers(List list) {

}

@Override

public Validator getValidator() {

return null;

}

@Override

public MessageCodesResolver getMessageCodesResolver() {

return null;

}

}

这样就解决了无法访问swagger-ui的问题了。
