创建SpringDoc配置文件

application.yml 配置

server:port: 8080# ======== SpringDocs文档配置 ========
springdocs:title: SpringBoot3.2.0 API Docsdescription: SpringBoot3 + OpenAPI Docsversion: 0.0.1scheme: Bearerheader: Authorization

OpenAPI配置文件

OpenAPI 与 Swagger的 API对应

@Api → @Tag
@ApiIgnore → @Parameter(hidden = true) or @Operation(hidden = true) or @Hidden
@ApiImplicitParam → @Parameter
@ApiImplicitParams → @Parameters
@ApiModel → @Schema
@ApiModelProperty(hidden = true) → @Schema(accessMode = READ_ONLY)
@ApiModelProperty → @Schema
@ApiOperation(value = "foo", notes = "bar") → @Operation(summary = "foo", description = "bar")
@ApiParam → @Parameter
@ApiResponse(code = 404, message = "foo") → @ApiResponse(responseCode = "404", description = "foo")
