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>
