swagger有什么用 Swagger包含的工具集 swagger的使用步骤
swagger的相关注解 Docket的源码 了解swagger的作用和概念了解前后端分离在SpringBoot中集成Swagger swagger是什么 swagger 是一个规范和完整的框架用于生成、描述、调用和可视化 RESTful 风格的 Web 服务。直接运行可以在线测试API接口API是前后端的重要联系纽带支持多种语言java, php...总体目标是使客户端和文件系统作为服务器以同样的速度来更新。文件的方法参数和模型紧密集成到服务器端的代码允许API来始终保持同步。 swagger有什么用 接口文档自动在线生成。功能测试。 Swagger包含的工具集 Swagger-tools提供各种与Swagger进行集成和交互的工具。例如模式检验、Swagger1.2文档转换成Swagger2.0文档等功能。Swagger-core用于Java/Scala的Swagger实现。与JAX-RS(Jersey、Resteasy、CXF…、Servlets和Play框架进行集成。Swagger-js用于JavaScript的Swagger实现。Swagger-node-expressSwagger模块用于node.js的Express web应用框架。Swagger-ui一个无依赖的HTML、JS和CSS集合可以为Swagger兼容API动态生成优雅文档。Swagger-codegen一个模板驱动引擎通过分析用户Swagger资源声明以各种语言生成客户端代码 swagger的使用步骤 引入pomm的相关依赖在代码中加入相应的配置新建config包写入swaggerConfig配置类在basePackage指定的路径下使用swagger使用api注解启动项目浏览器打开http://ip:port/swagger-ui.html swagger 的相关依赖

RequestMapping(/api)
Api(tags 标准演示接口)
public class ApiController {Resourceprivate ObjectMapper mapper;PostMapping(/ps)ApiOperation(value 接受json参数, notes 演示json参数是否接受成功)public String post(ApiParam(name 接收json参数, defaultValue {})RequestBody String json) throws IOException {Map map mapper.readValue(json, Map.class);System.out.println(map);return json;}
}swagger的相关注解 Configuration表明这是一个配置类EnableSwagger2开启Swagger2Api放在类上说明该类的作用。ApiOperation放在方法上说明该方法的作用。ApiImplicitParams用在方法上包含一组参数说明。 code数字例如400message信息例如“请求参数没填好”response抛出异常的类ApiImplicitParam用来注解来给方法入参增加说明一个请求能数。ApiResponses用于表示一组响应。ApiResponse用在ApiResponses中一般用于表达一个错误的响应信息ApiModel用对象来接收参数描述一个Model的信息一般用于在请求参数无法使用ApiImplicitParam注解进行描述的时候ApiModelProperty用对象接收参数时描述对象的一个字段ApiIgnore使用该注解忽略这个APIApiError 发生错误返回的信息 Docket的源码
