er文档自动生成工具

本文讲解如何在spring-boot中使用swagger文档自动生成工具

目录结构

springboot成神之——swagger文档自动生成工具-LMLPHP

说明

swagger的使用本身是非常简单的,因为所有的一切swagger都帮你做好了,你所要做的就是专注写你的api信息

swagger自动生成html文档并且打包到jar包中

本文不仅用了swagger,JSR 303注释信息也支持使用

开启api界面

在你做好了上述的步骤以后,运行项目

直接访问 yourapiurl/v2/api-docs 查看json数据

直接访问 yourapiurl/swagger-ui.html 查看文档界面

JSR 303注释信息

@NotNull(message = "...")
@NotBlank(message = "...")
@Pattern(regexp = "[a-z-A-Z]*", message = "...")
@Past(message = "过去的日期...")
@Min(value = 1, message = "必须大于或等于1")
@Max(value = 10, message = "必须小于或等于10")
@Email(message = "Email Address")

Swagger核心注释

@ApiModel               返回json对象描述
@ApiModelProperty 返回json对象属性描述
@ApiResponses 设置状态码含义
@Api 控制器描述
@ApiOperation api描述
@ApiParam api参数描述
