解决SpringBoot2.6.7 集成Swagger2.9.2 访问404的问题

最近使用最新的SpringBoot2.0集成Swagger2的时候遇到一个问题，集成之后打开Swagger页面的时候出现404，后台提示找不到swagger-ui的页面。于是我看了下项目依赖swagger的结构：

可以看到 swagger-ui.html 在META-INF/resources目录下，所以我们需要手动的将静态资源路径指向这里，在java中配置为：

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

/**

@Configuration
@EnableSwagger2
public class SwaggerConfig extends WebMvcConfigurationSupport {

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.xqnode.controller"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("接口总览")
                .description("测试")
                .version("1.0")
                .build();
    }

	@Override
    protected void addResourceHandlers(ResourceHandlerRegistry registry) {
        // 解决静态资源无法访问
        registry.addResourceHandler("/**")
                .addResourceLocations("classpath:/static/");
        // 解决swagger无法访问
        registry.addResourceHandler("/swagger-ui.html")
                .addResourceLocations("classpath:/META-INF/resources/");
        // 解决swagger的js文件无法访问
        registry.addResourceHandler("/webjars/**")
                .addResourceLocations("classpath:/META-INF/resources/webjars/");
    }
}
