配置文件yml添加 servlet: context-path: /api后，swagger2在配置文件需要添加什么？

在配置文件中添加以下内容即可：

server:
  servlet:
    context-path: /api

springfox:
  documentation:
    swagger-ui:
      enabled: true
    open-api:
      enabled: true
  swagger-ui:
    base-url: /api/swagger-ui/
    config:
      deepLinking: true
      displayOperationId: true
      defaultModelsExpandDepth: 2
      defaultModelExpandDepth: 2
      defaultModelRendering: "example"
      displayRequestDuration: false
      docExpansion: "none"
      filter: false
      maxDisplayedTags: 5
      operationsSorter: "alpha"
      showExtensions: false
      tagsSorter: "alpha"
      url: "/api/v2/api-docs"
  springfox:
    api:
      info:
        title: "API"
        description: "API documentation"
        version: "1.0.0"
      schemes:
        - "http"
        - "https"
      paths:
        include: "/api/.*"
      produces:
        - "application/json"
      consumes:
        - "application/json"

这里的`/api`是你的servlet的context-path，需要与servlet配置文件中的一致。另外，需要根据实际情况更改`schemes`、`paths`、`produces`、`consumes`等参数，以便生成正确的API文档。
