本文整理了Java中org.eclipse.jetty.webapp.WebAppContext.preConfigure()方法的一些代码示例，展示了WebAppContext.preConfigure()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。WebAppContext.preConfigure()方法的具体详情如下：
包路径：org.eclipse.jetty.webapp.WebAppContext
类名称：WebAppContext
方法名：preConfigure

WebAppContext.preConfigure介绍

[英]Pre configure the web application.

The method is normally called from #start(). It performs the discovery of the configurations to be applied to this context, specifically:

• Instantiate the Configuration instances with a call to #loadConfigurations().
• Setup the default System classes by calling #loadSystemClasses()
• Setup the default Server classes by calling loadServerClasses()
• Instantiates a classload (if one is not already set)
• Calls the Configuration#preConfigure(WebAppContext) method of all Configuration instances.
  [中]预先配置web应用程序。
  该方法通常从#start（）调用。它会发现要应用于此上下文的配置，具体来说：
  *通过调用#loadConfigurations（）实例化配置实例。
  *通过调用#loadSystemClasses（）设置默认系统类
  *通过调用loadServerClasses()设置默认服务器类
  *实例化类加载（如果尚未设置）
  *调用所有配置实例的配置#预配置（WebAppContext）方法。
