本文通过一个简单的Java Web应用程序示例展示了如何使用HttpServletRequest对象获取各种路径信息，包括basePath、contextPath、servletPath、requestURI等，并解释了这些路径的区别及应用场景。

test1.jsp=======================

<a href ="test.jsp?p=fuck">跳转到test2</a>

test2.jsp=======================

<%@ page language="java" import="java.util.*" pageEncoding="gb2312"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

out.println("basePath:"+basePath);
out.println(" ");
out.println("getContextPath:"+request.getContextPath());
out.println(" ");
out.println("getServletPath:"+request.getServletPath());
out.println(" ");
out.println("getRequestURI:"+request.getRequestURI());
out.println(" ");
out.println("getRequestURL:"+request.getRequestURL());
out.println(" ");
out.println("getRealPath:"+request.getRealPath("/"));
out.println(" ");
out.println("getServletContext().getRealPath:"+getServletContext().getRealPath("/"));
out.println(" ");
out.println("getQueryString:"+request.getQueryString());

显示结果：

basePath:http://localhost:8080/test/

getContextPath:/test
getServletPath:/test.jsp
getRequestURI:/test/test.jsp
getRequestURL:http://localhost:8080/test/test.jsp
getRealPath:D:\Tomcat 6.0\webapps\test\
getServletContext().getRealPath:D:\Tomcat 6.0\webapps\test\
getQueryString:p=fuck
