添加Swagger 配置类io.springfox springfox-swagger2 2.7.0 io.springfox springfox-swagger-ui 2.7.0
@Configuration
@EnableSwagger2
public class SwaggerConfig {
@Bean
public Docket productApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class)) //添加ApiOperiation注解的被扫描
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder().title("swagger和springBoot整合").description("swagger的API文档")
.version("1.0").build();
}
}
swagger-ui 展示
访问 http://localhost:8080/swagger-ui.html 即可看到对应的UI 界面
- 找不到swagger-ui 界面，但是 http://localhost:8080/v2/api-docs 访问正常【确认swagger 的两个jar 包是否都添加到了pom 文件中】
- 依赖于spring boot 版本不匹配【我这里springboot 版本：2.5.5，配swagger：2.7.0 正好展示，如果spring boot ：2.6.7 则显示失败，报错如下，直接降低spring boot 版本即可】

最新版springboot 2.7.0 可以和下面两个文件搭配使用
【但是需要将@EnableSwagger2 放到springboot 启动类，另外还需要添加下面的配置文件到application.yml 中】
mvc:
pathmatch:
matching-strategy: ant_path_matcher
io.springfox springfox-swagger2 2.7.0 ``` io.springfox springfox-swagger-ui 2.7.0
