我正在尝试使用 loginServlet 从 jsp 页面登录。它重定向到 servlet，但不进行身份验证并引发错误。这是代码:
JSP 文件:
<div class="container">
<div class="row">
<div class="box">
<div class="col-md-6 col-md-offset-4">
<h2 class="intro-text">Welcome! Login here:</h2>
<form class="form-horizontal" action="LoginServlet" method="POST">
<div class="form-group">
<label class="control-label col-sm-2" for="username">Username:</label>
<div class="col-sm-4">
<input type="text" class="form-control" id="username" placeholder="Enter username" name="un">
</div>
</div>
<div class="form-group">
<label class="control-label col-sm-2" for="pwd">Password:</label>
<div class="col-sm-4">
<input type="password" class="form-control" id="pwd" placeholder="Enter password" name="pwd">
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-4">
<div class="checkbox">
<label><input type="checkbox" name="remember"> Remember me</label>
</div>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-4">
<button type="submit" class="btn btn-success">Submit</button>
</div>
</div>
</form>
</div>
</div>
</div>
</div>
登录Servlet:
@WebServlet("/LoginServlet")
public class LoginServlet extends HttpServlet {
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, java.io.IOException {
try
{
User user = new User();
user.setUsername(request.getParameter("un"));
user.setPassword(request.getParameter("pwd"));
PrintWriter writer = response.getWriter();
// build HTML code
String htmlRespone = "<html>";
htmlRespone += "<h2>Your username is: " + user.getUsername() + "<br/>";
htmlRespone += "Your password is: " + user.getPassword() + "</h2>";
htmlRespone += "</html>";
writer.println(htmlRespone);
if (authUser(user))
{
System.out.println("exists!");
HttpSession session = request.getSession(true);
session.setAttribute("currentSessionUser",user);
response.sendRedirect("home.jsp"); //logged-in page
}
else {
System.out.println("not!");
response.sendRedirect("invalidLogin.jsp"); //error page
}
}
catch (Throwable theException)
{
System.out.println(theException);
}
}
public boolean authUser(User user) {
// TODO Auto-generated method stub
User userDB = UserDAO.getUserByUsername(user.getUsername());
System.out.println(userDB.getUsername()+" "+userDB.getPassword());
System.out.println(user.getUsername()+" "+user.getPassword());
if (userDB != null && userDB.getUsername().equals(user.getUsername()) && userDB.getPassword().equals(user.getPassword())) {
return true;
} else {
return false;
}
}
}
UserDAO 中的 getUserByUsername 方法:
public static User getUserByUsername(String username) {
Session session = factory.openSession();
Transaction tx = null;
List<User> users = null;
tx = session.beginTransaction();
Query query = session.createQuery("FROM User WHERE username = :username ");
query.setParameter("username", username);
List<User> result = query.list();
tx.commit();
return result != null && !result.isEmpty() ? result.get(0) : null;
}

我尝试添加互联网上建议的其他 jar 以及我在这里找到的其他一些东西，但到目前为止没有任何效果。我希望它在身份验证后将我重定向到指定的页面。有什么想法吗？
非常感谢!
最佳答案
我实际上遇到了同样的问题..我的解决方案基于以下内容:
RxInvokerProvider 位于版本 2.1 的 jaxrs-api 中 -> 您引用的是 2.0
jersey 2.26 依赖于 jaxrs 2.1
在此问题之后，您将面临“注入(inject)”问题( https://github.com/jersey/jersey/blob/12e5d8bdf22bcd2676a1032ed69473cf2bbc48c7/docs/src/main/docbook/migration.xml )，因此您将需要 jersey-hk 依赖项
<dependency>
<groupId>org.glassfish.jersey.inject</groupId>
<artifactId>jersey-hk2</artifactId>
<version>${jersey.version}</version>
</dependency>
关于hibernate - java.lang.ClassNotFoundException : javax. ws.rs.client.RxInvokerProvider，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45530132/
