SpringBoot2.0集成Swagger2访问404的问题-解决方法

@Configuration
@EnableSwagger2
public class Swagger2Config extends WebMvcConfigurationSupport {
    /**

    private Logger log = LoggerFactory.getLogger(Swagger2Config.class);

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(createApiInfo())
                .pathMapping("/api/v1")
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.chen.springbootdemo.controller"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo createApiInfo() {
        return new ApiInfoBuilder().title("SpringBoot中使用Swagger2构建RESTful APIs")
                .description("请看博客:https://blog.youkuaiyun.com/qq_38685242")
                .contact(new Contact("cgy", "https://blog.youkuaiyun.com/qq_38685242", "1192165267@qq.com"))
                .version("1.0")
                .build();
    }
    /**
     * 防止@EnableMvc把默认的静态资源路径覆盖了，手动设置的方式
     * @param registry
     */
    @Override
    protected void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/**").addResourceLocations("classpath:/META-INF/resources/").setCachePeriod(0);
    }
}

注意：

• 继承WebMvcConfigurationSupport
• 实现addResourceHandlers方法
• 看代码的展示
• 修改完后访问ip+port/swagger-ui.html访问
