我的swaggerConfig类如下
package com.wkb.config; import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration; import
org.springframework.web.servlet.config.annotation.EnableWebMvc; 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 */
@Configuration @EnableWebMvc public class SwaggerConfig{ @Bean public Docket
createRestApi(){ return new Docket(DocumentationType.SWAGGER_2) .apiInfo(apiInfo
()) .select() //.apis(RequestHandlerSelectors.any()) .apis(
RequestHandlerSelectors.basePackage("com/wkb/controller")) .paths(
PathSelectors.any()) .build(); } private ApiInfo apiInfo(){ return new
ApiInfoBuilder() .title("SpringBoot API Doc") .description("This is a restful
api document of Spring Boot.") .version("1.0") .build(); } }
<>解决
在swaggerConfig类上加@EnableWebMvc
