• Swagger配置扫描接口
  Docket.select

//配置了Swagger的Docket的bean实例
@Bean
public Docket docket() {
    return new Docket(DocumentationType.SWAGGER_2)
            .apiInfo(apiInfo())
            .select()
            .apis(RequestHandlerSelectors.basePackage("com.example.controller"))
            .build();
}

• 配置API文档的分组

.groupName("A")

• 配置多个分组

@Bean
public Docket docket1(){
    return new Docket(DocumentationType.SWAGGER_2).groupName("A");
}

@Bean
public Docket docket2(){
    return new Docket(DocumentationType.SWAGGER_2).groupName("B");
}

@Bean
public Docket docket3(){
