Swagger 3.0 中注解详细示例

Swagger 3.0 提供了丰富的注解来详细描述 API 的请求和响应。以下是一个使用 @Operation、@Parameter、@RequestBody 和 @ApiResponse 注解的示例，展示了如何设置请求头、请求参数、路径变量、请求体和响应体。代码中未使用 DTO 对象，而是使用 Map 来传递参数和响应。通过 @Parameter 注解，可以定义查询参数、路径变量和请求头。@RequestBody 注解用于描述请求体的结构，而 @ApiResponse 注解则用于定义成功的响应内容。此示例展示了如何在 Swagger 中详细描述 API 的各个部分，帮助开发者理解和使用 API。

为了演示如何详细设置每个请求头、请求参数、路径变量、请求体、响应体，下面的代码没有使用 DTO 对象，参数和响应都使用的 Map。
