FirstServlet java:

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;

public class FirstServlet extends HttpServlet {
   @Override
   protected void service(HttpServletRequest request, HttpServletResponse response) throws IOException {
       //接受请求发来的参数
       String name=request.getParameter("name");
       String html="<h1 style='color:red'>hi,"+name+"!</h1><hr/>";
       PrintWriter out=response.getWriter();
       out.println(html);//将html发送回浏览器
   }
}
