創建好的工程目錄如下：
一開始我現在WEB-INF中創建了一個test.jsp但發現tomcat上面運行錯誤
錯誤原因：
在 Eclipse的“包資源管理器(Package Explorer)”檢查文件存放的位置。由於META-INF
WEB-INF文件夾下的內容無法對外發布，所以，如果你引用了帶這兩個目錄的文件，肯定是不允許。
解決辦法：將WEB-INF中的test.jsp拖到WebContent中
再次運行：
二、創建servlet實例
如圖
HelloServlet的代碼如下：
package com.chenjn.www;
import java.io.IOException;
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 implementation class HelloServlet
*/
@WebServlet("/HelloServlet")
public class HelloServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* @see HttpServlet#HttpServlet()
*/
public HelloServlet() {
super();
// TODO Auto-generated constructor stub
}
/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
response.setCharacterEncoding("GBK");
response.getWriter().write("hello world！");
}
/**
* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doGet(request,response);
// TODO Auto-generated method stub
}
}
重啟tomcat 服務器運行結果如下：
