在Eclipse中创建Dynamic Web Project

Posted 2020-10-16 陈醋

创建好的工程目录如下：

 

一开始我现在WEB-INF中创建了一个test.jsp但发现tomcat上面运行错误

错误原因：

在 Eclipse的“包资源管理器(Package Explorer)”检查文件存放的位置。由于META-INF

WEB-INF文件夹下的内容无法对外发布，所以，如果你引用了带这两个目录的文件，肯定是不允许。

解决办法：将WEB-INF中的test.jsp拖到WebContent中

再次运行：

二、创建servlet实例

如图

 

HelloServlet的代码如下：

 

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
}

}

 

重启tomcat 服务器运行结果如下：
