@Configuration
@EnableSwagger2WebMvc
public class Knife4jConfiguration {

    @Bean(value = "defaultApi2")
    public Docket defaultApi2() {
        Docket docket=new Docket(documentationType.SWAGGER_2)
                .apiInfo(new ApiInfoBuilder()
                        //.title("swagger-bootstrap-ui-demo RESTful APIs")
                        .description("# swagger-bootstrap-ui-demo RESTful APIs")
                        .termsOfServiceUrl("http://www.xx.com/")
                        .contact("xx@qq.com")
                        .version("1.0")
                        .build())
                //分组名称
                .groupName("2.X版本")
                .select()
                //这里指定Controller扫描包路径
                .apis(RequestHandlerSelectors.basePackage("com.github.xiaoymin.knife4j.controller"))
                .paths(PathSelectors.any())
                .build();
        return docket;
    }
}

官网并没有指明要指定静态文件地址 直接访问可能会报404错误

@SpringBootApplication
public class DemoApplication  implements WebMvcConfigurer {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        // 解决swagger无法访问
        registry.addResourceHandler("doc.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/");
    }
}

server:
	port: 8081

// 如果启动报这个错误
Failed to start bean ‘documentationPluginsBootstrapper‘

那么在配置文件中添加

spring:
  mvc:
    pathmatch:
      matching-strategy: ANT_PATH_MATCHER
