java获取服务器路径和类加载路径

public void uploadPic(HttpServletRequest request){
	int[] ports = new int[3];
	ports[0] = request.getServerPort();     //获取服务器端口
	ports[1] = request.getLocalPort();      //获取本地端口
	ports[2] = request.getRemotePort();     //获取远程客户端端口
	String[] strings = new String[12];
	strings[0] = request.getSession().getServletContext().getRealPath("/"); //获取项目所在服务器的全路径 C:\Users\Administrator\AppData\Local\Temp\tomcat-docbase.8827146702237826359.8088\
	strings[1] = request.getServletPath();  //获取客户端请求的路径名   /user/test
	strings[2] = request.getServerName();   //获取服务器地址   localhost
	strings[3] = request.getContextPath();  //获取项目名称
	strings[4] = request.getLocalAddr();    //获取本地地址    0:0:0:0:0:0:0:1
	strings[5] = request.getLocalName();    //获取本地IP映射名 0:0:0:0:0:0:0:1
	strings[6] = request.getRemoteAddr();   //获取远程主机地址  0:0:0:0:0:0:0:1
	strings[7] = request.getRemoteHost();   //获取远程主机    0:0:0:0:0:0:0:1
	strings[8] = request.getRequestURI();   //获取包含项目名称的请求路径 /user/test
	strings[9] = request.getRequestURL().toString();    //获取请求的全路径  http://localhost:8088/user/test
	strings[10] = this.getClass().getResource("/").getPath();   //获取类加载的根路径 /D:/HI/worryFree/shop/web/target/classes/
	strings[11] = this.getClass().getResource("").getPath();    //获取当前类的所在工程路径; 如果不加“/”  获取当前类的加载目录 /D:/HI/worryFree/shop/web/target/classes/com/ouyin/web/Controller/
