通过ServletContext类的getRealPath()方法获取服务器的真实地址

通过ServletContext类的getRealPath()方法获取服务器的真实地址：

package com.wgh;

import java.io.IOException;

import java.io.PrintWriter;

import javax.servlet.ServletContext;

import javax.servlet.ServletException;

import javax.servlet.annotation.WebServlet;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

/**

 * Servlet实现类SurePath

 */

@WebServlet("/SurePath")

public class SurePath extends HttpServlet {
private static final long serialVersionUID = 1L;

       

    /**

     * @see HttpServlet#HttpServlet()

     */

    public SurePath() {

        super();

    }

/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

        response.setContentType("text/html; charset=UTF-8");

        ServletContext context = this.getServletContext();

        PrintWriter out = response.getWriter();

        out.print("获取当前服务器的真实路径：" + context.getRealPath("") + "");
}

}
