这是请求的servlet
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
@WebServlet("/LoginServlet")
public class LoginServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException {
doPost(req, resp);
}
@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws IOException {
req.setCharacterEncoding("utf-8");
resp.setCharacterEncoding("utf-8");
String username = req.getParameter("username");
String userpass = req.getParameter("password");
List<User> list = new ArrayList<User>();
UserBusy usb = new UserBusyImpl();
try {
list = usb.UserLogin(username,userpass);
if(list==null){
req.setAttribute("fail","账号或密码错误,请重新输入");
req.getRequestDispatcher("/Login.jsp").forward(req,resp);
}else {
req.setAttribute("username",username);
req.getRequestDispatcher("/Success.jsp").forward(req,resp);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
pom.xml我也配置依赖了,但是不知道问题出在哪里,求解答,谢谢!
