firstservlet.java

对入学者很实用用JAVA的基本语言写的

package page;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class FirstServlet extends HttpServlet {

	public FirstServlet() {
		super();
	}

	public void destroy() {
		super.destroy();
	}

	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		doPost(request, response);

	}

	public void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {

		request.setCharacterEncoding("UTF-8");
		String name = request.getParameter("name");
		String pass = request.getParameter("pass");
		String sql = "INSERT INTO STUDENTS(NAME,PASS) VALUES(?,?)";
		int ret = JDBCTraining.update(sql, name, pass);
		response.setContentType("text/html; charset=UTF-8");
		PrintWriter out = response.getWriter();
		if (ret > 0) {
			out.println("成功");
		} else {
			out.println("失败");
		}
	}

	public void init() throws ServletException {

	}

}
