新建一個(gè)com.autumn.servlet.Dispatcher.java文件  package com.autumn.servlet; import javax.servlet.ServletConfig; import javax.servlet.ServletException; /** * Created by Administrator on 2018/6/6. */ public class Dispatcher extends org.springframework.web.servlet.DispatcherServlet { private static final long serialVersionUID = -7677752525845571027L; @Override public void init(ServletConfig config) throws ServletException { super.init(config); String appName = config.getInitParameter("appName").trim(); //web.xml中初始化參數(shù) config.getServletContext().setAttribute("appName", appName); //將這個(gè)appName放入servletContext中 } }

其他方法不用統(tǒng)一管理的${appName}可以用<base href="">標(biāo)簽 <base> 標(biāo)簽為頁面上的所有鏈接規(guī)定默認(rèn)地址或默認(rèn)目標(biāo)。通常情況下，瀏覽器會(huì)從當(dāng)前文檔的 URL 中提取相應(yīng)的元素來填寫相對(duì) URL 中的空白。 jsp中先聲明schema://server:port/contextpath/ <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> 然后在頁面上聲明base標(biāo)簽，指定base的url <base href="<%=basePath%>"> 這樣的話頁面中所有的圖片或這里鏈接都會(huì)在schema://server:port/contextpath/下面找
