Swagger
一个规范完整的框架
用以生成,描述,调用和可视化
主要作用为
自动生成接口文档
方便后端开发进行接口调试
Knife4j
为Java MVC框架集成
依赖引入:
xml
<!-- knife4j版接口文档 访问/doc.html-->

Swagger配置类
构建了指定相关信息的接口文档

Swagger的常用注解
java
@Api//用在类上,用以描述控制类的作用
@ApiOperation//用在方法上,用以描述接口的作用
@ApiParam//用在方法上描述单个参数的含义
@ApilmplicitParam//描述单个形参
@ApilmplicitParams//描述多个形参
@ApiModel//用在实体类上描述实体类
@ApiModelProperty//用在实体类的属性上描述实体类的字段含义
