获取Request请求的路径信息
从Request对象中可以获取各种路径信息，以下例子：假设请求的页面是index.jsp,项目是WebDemo，则在index.jsp中获取有关request对象的各种路径信息如下String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";String remoteAddress=request.getRemoteAddr();String servletPath=request.getServletPath();String realPath=request.getRealPath("/");String remoteUser=request.getRemoteUser();String requestURI=request.getRequestURI();out.println("path:"+path+"
");out.println("basePath:"+basePath+"
");out.println("remoteAddr:"+remoteAddress+"
");out.println("servletPath:"+servletPath+"
");out.println("realPath:"+realPath+"
");out.println("remoteUser:"+remoteUser+"
");out.println("requestURI:"+requestURI+"
");结果：path:/WebDemobasePath:http://localhost:8683/WebDemo/remoteAddr:127.0.0.1servletPath:/index.jsprealPath:D:\apache-tomcat-6.0.13\webapps\WebDemo\remoteUser:nullrequestURI:/WebDemo/index.jsp从上不难看出request各个对应方法所代表的含义
