java – Dispatcher servlet spring和url模式

前端之家收集整理的这篇文章主要介绍了java – Dispatcher servlet spring和url模式前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我是 spring框架的新手今天我遇到了web.xml文件中的调度程序servlet配置,我想出了一个关于url模式的问题,比如这个语法/.那么,如果我在tomcat服务器中部署web应用程序,实际上“/”符号适用的是:host:port /或host:port / myWeb /

解决方法

模式/将使您的servlet成为应用程序的默认servlet,这意味着它将获取没有其他完全匹配的每个模式.

URL模式映射:

  • A string beginning with a / character and ending with a /* suffix is used for path mapping.
  • A string beginning with a *. prefix is used as an extension mapping.
  • A string containing only the / character indicates the default servlet of the application. In this case the servlet path is the request URI minus the context path and the path info is null.
  • All other strings are used for exact matches only.

路径映射规则

  1. The container will try to find an exact match of the path of the request to the path of the servlet. A successful match selects the servlet.
  2. The container will recursively try to match the longest path-prefix. This is done by stepping down the path tree a directory at a time,using the / character as a path separator. The longest match determines the servlet selected.
  3. If the last segment in the URL path contains an extension (e.g. .jsp),the servlet container will try to match a servlet that handles requests for the extension. An extension is defined as the part of the last segment after the last . character.
  4. If neither of the prevIoUs three rules result in a servlet match,the container will attempt to serve content appropriate for the resource requested. If a default servlet is defined for the application,it will be used.
