2.連接數據庫 add_message.jsp

</HEAD>
<BODY>
<%
//數據庫
String title=request.getParameter("title");
String content=request.getParameter("content");
java.util.Date date=new java.util.Date();
String datetime=new Timestamp(date.getTime()).toString();
String userName="root";
String psw="123456";
Class.forName("com.mysql.jdbc.Driver").newInstance();
String url="jdbc:mysql://localhost:3306/liuyan?useUnicode=true&characterEncoding=utf-8"; //JDBC的URL
Connection con=DriverManager.getConnection(url,userName,psw);
out.println("<script language='javascript'>alert('數據庫連接成功！');</script>");
PreparedStatement stm=con.prepareStatement("Insert into message values(?,?,?)");
stm.setString(1,title);
stm.setString(2,content);
stm.setString(3,datetime);
int rst = stm.executeUpdate();
if (rst != 0){
out.println("<script language='javascript'>alert('發佈成功');window.location.href='liuyan.html';</script>");
}
else{
out.println("<script language='javascript'>alert('發佈失敗');window.location.href='liuyan.html';</script>");
}
con.close();
stm.close();
%>
</body>
</html>
3.查看留言 view_message.jsp
