protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String username = request.getParameter("u");
String password = request.getParameter("p");
Connection con = DBConnection.Connect();
String sql = "select *from users where name=? and pass=?";
try {
PreparedStatement ps = con.prepareStatement(sql);
ps.setString(1, username);
ps.setString(2, password);
ResultSet rs = ps.executeQuery();
request.getRequestDispatcher("WelcomeServlet").forward(request, response); //This line calls another servlet
} catch (SQLException e) {
System.out.println(e.toString());
}
}
}
public class WelcomeServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String username = request.getParameter("username");
response.setContentType("html/text");
PrintWriter pw = response.getWriter();
pw.write("<html><body>");
pw.write("<title>Welcome User</title>");
pw.write("<h1>" + username + "</h1>");
pw.write("</body></html>");
pw.close();
}
我希望验证servlet调用welcome servlet，但是它询问我是否要下载验证servlet文件.PFA以获取更多详细信息 I am getting the popup to download Validate Ser
答案 0 :(得分：1)
内容类型应为text/html（您编写了html/text），否则浏览器不知道如何处理该文件并要求下载。
值得一提的代码还有一些其他问题
u，而在另一个servlet中使用username。
