使用HttpServlet简单实例



package com.kettas.servlet ;

import javax.servlet.* ;

import javax.servlet.http.* ;

import java.io.* ;

public class LoginServlet extends HttpServlet{

    @Override 

    public void service( HttpServletRequest request , HttpServletResponse response )

        throws ServletException , IOException 

    {   response.setContentType("text/html; charset=GB2312"); // 注意设置编码的方式

        request.setCharacterEncoding("GB2312");

        PrintWriter out = response.getWriter();

        // 取得客户端提交的数据 

        String name = request.getParameter( "userName" ) ;

        String pwd = request.getParameter( "password" ) ;

        out.println("<html>");

        out.println("<body>");

        out.println("<h1>");

        out.println("Name : " + name + "   " + "Password : " + pwd);

        out.println("</h1>");

        out.println("</body>");

        out.println("</html>");

        out.flush();

    }

}

配置文件web.xml片段：



<servlet> 

    <servlet-name>login</servlet-name>

    <servlet-class>com.kettas.servlet.LoginServlet</servlet-class>

</servlet>                                      

<servlet-mapping>       

    <servlet-name>login</servlet-name>

    <url-pattern>/login</url-pattern>

</servlet-mapping>
