java.lang.ClassNotFoundException：javax.ws.rs.client.RxInvokerProvider

我试图使用loginServlet从jsp页面登录。它重定向到servlet，但它不会进行身份验证并引发错误。下面是代码：java.lang.ClassNotFoundException：javax.ws.rs.client.RxInvokerProvider

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>

LoginServlet：从UserDAO的

@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; 
     } 
    } 

}

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; 

    }

我尝试添加在互联网上提出的其他罐和一些其他的事情，我在这里找到，但没有到目前为止的工作。我希望它在认证后将我重定向到指定的页面。有任何想法吗？

非常感谢！

java.lang.ClassNotFoundException: javax.ws.rs.client.RxInvokerProvider异常发生在初始化期间，而不是登录期间。请求只能在日志中最后一行之后处理：INFO: Starting ProtocolHandler ["http-bio-8080"]。

为了解决这个异常的根本原因，在调试器中运行tomcat，在ClassNotFoundException上设置异常断点并检查Servlet的实际类型（堆栈跟踪中有GenericServlet.init()）。这将是您需要修复的servlet。很可能通过将所需的代码（或任何传递依赖项）添加到类路径中。

除此之外，这段代码是错了相当多的层面：

你输出写入到响应您重定向之前：一旦文本已被发送到浏览器，你不会可以重新定向，因为这需要编写HTTPS标头。当他们已经被发送时，你运气不好，会产生更多的例外。
你没有在任何异常中恢复你的事务（例如，commit/rollback应该在finally块中） - 但至少你不倾向于SQL注入。
您正在将明文密码存储在数据库中
当您长期解决此问题时您正在实施自己的登录，例如，通过容器（阅读servlet规范）

感谢您的回复！我解决了错误的代码情况，但仍然无法找到最后一个要点，即servlet规范中的容器。所以我不知道我是否应该专注于解决我的servlet问题或学习容器并将它们用于身份验证 –

如果我从主类运行相同的方法authUser（User），它的工作完美。为什么从一个servlet中导致问题？如果我没有向servlet发出任何请求，但只是比较一些硬编码的用户和密码，它也可以工作。我对servlet真的很陌生，我真的很困惑这种情况 –

authUser不会导致问题，至少在你发布的stacktrace中有一个坚果。确保所有必需的依赖项（jar文件）都部署在WEB-INF/lib中以摆脱CnF扩展。并且接受在进行身份验证之前发生的异常（至少是您在问题中发布的异常）。您的身份验证问题要么是独立的，要么是后续问题 - 我无法确定，因为我没有看到身份验证失败。 –
