最近试了试swagger接口文档，swagger版本3.0.0。以为和以前的低版本的swagger使用方法一致，可是启动过程中出现了各种问题（启动失败，访问失败），网上找了一圈各种解决方案都没有在本机生效，只有自己研究研究了。
其实高版本和低版本的不同只体现在引入pom和配置类使用的注解上
pom文件：
<!-- spring-boot-starter-parent 2.2.2.RELEASE --> <dependencies> <!-- swagger
3.0.0 --> <dependency> <groupId>io.springfox</groupId> <artifactId>
springfox-boot-starter</artifactId> <version>3.0.0</version> </dependency> <!--
低版本的swagger --> <!--<dependency> <groupId>io.springfox</groupId>
<artifactId>springfox-swagger-common</artifactId> <version>2.9.2</version>
</dependency> <dependency> <groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId> <version>2.9.2</version>
</dependency>--> </dependencies>
配置类：
@Configuration //@EnableSwagger2 // 老版本开启swagger //@EnableOpenApi //
网上搜到的解决报错添加的 public class SwaggerConfig { @Bean public Docket createRestApi1() {
ApiInfo apiInfo = new ApiInfoBuilder() .title("我的接口文档") .contact(new Contact(
"mySwagger", "heheheh", "[email protected]")) .version("1.0") .description("接口文档描述")
.build(); //docket对象用于封装接口文档相关信息 Docket docket = new Docket(DocumentationType.
SWAGGER_2) .apiInfo(apiInfo) .groupName("用户接口组") .select() .apis(
RequestHandlerSelectors.basePackage("cn.xf.swagger.controller")) .build();
return docket; } }
启动项目，访问swagger，访问地址：localhost:端口号/swagger-ui
