SpringBoot整合Swagger生成接口文档

# 介绍: #

Swagger 是一款RESTFUL接口的文档在线自动生成+功能测试功能软件。本文简单介绍了在项目中集成swagger的方法和一些常见问题。 如果想深入分析项目源码，了解更多内容，见参考资料。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。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 让部署管理和使用功能强大的API从未如此简单。

### 关于swagger的更多注解的使用: ###

![20190218142509664.png][]

### 点击这个包下,然后看见下图的内容,点进去你想了解的注解,通过人家写的注释可以知晓注解和其参数的作用 ###

![20190218142421984.png][]

*  @Api：修饰整个类，描述Controller的作用
 *  @ApiOperation：描述一个类的一个方法，或者说一个接口
 *  @ApiParam：单个参数描述
 *  @ApiModel：用对象来接收参数
 *  @ApiProperty：用对象接收参数时，描述对象的一个字段
 *  @ApiResponse：HTTP响应其中1个描述
 *  @ApiResponses：HTTP响应整体描述
 *  @ApiIgnore：使用该注解忽略这个API
 *  @ApiError ：发生错误返回的信息
 *  @ApiImplicitParam：一个请求参数
 *  @ApiImplicitParams：多个请求参数
