最近使用最新的SpringBoot2.0整合Swagger2的時候遇到一個問題，整合之後開啟Swagger頁面的時候出現404，後臺提示找不到swagger-ui的頁面，百度了下找到下面的解決方法：

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;

/**
 * @author xiaqing
 */
@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.mongodb.controller"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("介面總覽")
                .description("測試")
                .version("1.0")
                .build();
    }

    /**
     * 防止@EnableMvc把預設的靜態資源路徑覆蓋了，手動設定的方式
     * @param registry
     */
    @Override
    protected void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/**").addResourceLocations("classpath:/META-INF/resources/").setCachePeriod(0);
    }
}

在swagger的配置類中繼承WebMvcConfigurationSupport，實現addResourceHandlers方法，設定靜態資源可訪問。

設定完成後重啟專案，就可以通過ip:port/swagger-ui.html正常訪問了。
