javaweb中servlet创建实例

最近初学javaweb，下面将介绍如何创建一个简单的javaweb实例。

首先把eclipse以及相应的Java jdk和Tomcat服务器配置完成。然后在eclipse里面新建Dynamic Web Project项目件。

在建好的项目中的doget方法中添加如下的代码：

package king;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;import javax.swing.JOptionPane;

/**
public class Firstking extends HttpServlet { * Servlet implementation class Firstking
*/
@WebServlet("/Firstking")
private static final long serialVersionUID = 1L;
public Firstking() { private static final Object[] OK = null;

/**
* @see HttpServlet#HttpServlet()
*/
super();
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // TODO Auto-generated constructor stub
}

/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
/** // TODO Auto-generated method stub
//response.getWriter().append("Served at: ").append(request.getContextPath());
response.getWriter().write("hello world!");
}

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
// TODO Auto-generated method stub
doGet(request, response);
} }

这样运行该Java文件就能够看到熟悉的hello word。哈哈。
