jsp.项目名称等

1、资料:在jsp页面中获取项目名称 - wjt276--Java - ITeye博客.html(https://wjt276.iteye.com/blog/455112

  el表达式:${pageContext.request.contextPath}

 1.1、ZC:我的测试代码:

<%
    System.out.println("request.getContextPath() : "+request.getContextPath());
    System.out.println("request.getScheme() : "+request.getScheme());
    System.out.println("request.getServerName() : "+request.getServerName());
    System.out.println("request.getServerPort() : "+request.getServerPort());
    
    String path = request.getContextPath();  
    String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
    System.out.println("basePath : "+basePath);
%>

  控制台 输出:

  request.getContextPath() : /DingYueHao
  request.getScheme() : http
  request.getServerName() : localhost
  request.getServerPort() : 8080
  basePath : http://localhost:8080/DingYueHao/
