1. 配置文件

import springfox.documentation.builders.ApiInfoBuilder;

public class Swagger2Config {

@Bean
public Docket createRestApi() {
    return new Docket(DocumentationType.SWAGGER_2)
            .apiInfo(new ApiInfoBuilder()
                    .title("阅文HR_绩效管理后台_接口文档")

                    .build())
            .enable(true)
            .select()

// .apis(RequestHandlerSelectors.basePackage("com.yhr.menu.controller"))

            .build();
}
private ApiInfo apiInfo() {
    return new ApiInfoBuilder()
            .title("阅文HR_绩效管理后台_接口文档")
            .description("绩效管理后台")
            .contact(new Contact("yhr", "url", "xxx@163.com"))

}

1. 1）controller 注解
   @Api(value = "菜单数据Controller", tags = { "菜单" }) `
   2）method 注解
   @ApiOperation(value = "初始化所有在职人员的菜单信息", notes = "计算所有人员的菜单显示权限，缓存到Redis，提升效率", httpMethod = "GET")`
   3）参数注解
   @ApiParam(name="appcode",value="应用clientid",required=true) @RequestParam("appcode")String appcode, @ApiParam(name="badge",value="员工工号",required=true)@RequestParam("badge")String badge`
