修改apache-tomcat-9.0.97\conf\logging.properties文件：
@WebServlet("/login")
public class LoginServlet extends HttpServlet {
@Override
protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
req.setCharacterEncoding("UTF-8");
String username = req.getParameter("username");
String userPwd = req.getParameter("userPwd");
System.out.println("用户名：" + username);
System.out.println("密码：" + userPwd);
resp.setContentType("text/html;charset=utf-8");
PrintWriter writer = resp.getWriter();
writer.write(username + "<h1>登录成功！</h1>");
writer.close();
