javaWeb学习—getRequestURI,getRequestURL等的学习

1：我的项目名称为 dufyun_SpringMVC 

2：我测试的地址为

${pageContext.servletContext.contextPath}/testName

3;后台获取的代码为：

@RequestMapping(value="/testName",method=RequestMethod.GET)public String testName(Model m ,HttpServletRequest request) throws UnsupportedEncodingException{System.out.println("request.getServerName()" + request.getServerName()); //服务的名称System.out.println("request.getServerPort()" + request.getServerPort());//服务的端口号System.out.println("request.getLocalName()" + request.getLocalName());//本地名称System.out.println("request.getLocalPort()" + request.getLocalPort());//本地端口号System.out.println("request.getProtocol()" + request.getProtocol());//传输协议System.out.println("request.getRealPath()" + request.getRealPath("/"));//获取项目地址System.out.println("request.getRequstURI()" + request.getRequestURI());//获取一个相对的地址System.out.println("request.getRequstURL()" + request.getRequestURL());//获取一个绝对的地址System.out.println("request.getContextPath()" + request.getContextPath());//项目的名称（项目的项目地址）System.out.println("request.getServletPath()" + request.getServletPath());//访问Servle的名称/*request.getServerName()localhostrequest.getServerPort()8080request.getLocalName()0:0:0:0:0:0:0:1request.getLocalPort()8080request.getProtocol()HTTP/1.1request.getRealPath()D:\KuYuPritace\SSH\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\dufyun_SpringMVCrequest.getRequstURI()/dufyun_SpringMVC/testNamerequest.getRequstURL()http://localhost:8080/dufyun_SpringMVC/testNamerequest.getContextPath()/dufyun_SpringMVCrequest.getServletPath()/testName
