Http status 401此请求需要HTTP认证（）。在Tomcat中6

我开发一个Web应用程序 enter image description here Http status 401此请求需要HTTP认证（）。在Tomcat中6

，如果我跑在Tomcat中6，它要求用户名和密码应用程序，但后3个attempsts它显示 enter image description here 在web.xml文件是

我想获得远程用户的用户名和密码该怎么办？这是我的servlet代码

package com.src; 

import java.io.IOException; 
import java.io.PrintWriter; 
import java.util.Enumeration; 

import javax.servlet.ServletException; 
import javax.servlet.http.HttpServlet; 
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 

import org.apache.tomcat.util.buf.Base64; 

public class remoteSample extends HttpServlet { 
    private static final long serialVersionUID = 1L; 

    /** 
    * @see HttpServlet#HttpServlet() 
    */ 
    public remoteSample() { 
     super(); 
     // TODO Auto-generated constructor stub 
    } 

    /** 
    * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response) 
    */ 
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 
     // TODO Auto-generated method stub 

     response.setContentType("text/html;charset=UTF-8"); 
     System.out.println("login info:"+request.getRemoteUser()); 
     System.out.println("Authentication type:"+request.getAuthType()); 

    } 

    /** 
    * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response) 
    */ 
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 
     // TODO Auto-generated method stub 
    } 

}

我应该改变我的服务器的Tomcat的server.xml中和web.xml的东西吗？

是你能解决这个问题？ – user911 2017-03-02 19:46:20

检查您在服务器中使用的领域名称&远程用户是否与以下名称匹配。

<realm-name>Authentication required</realm-name>

了解详情，请查看本link关于例外

请提供下面的代码在web.xml文件中可能会有所帮助。

<login-config> 
    <auth-method>BASIC</auth-method> 
    <realm-name>Basic Authentication Area</realm-name> 
</login-config>

请提供Tomcat中的用户角色和用户名

<tomcat-users> 
<user name="tomcat" password="tomcat" roles="tomcat" /> 
<user name="role1" password="tomcat" roles="role1" /> 
<user name="both" password="tomcat" roles="tomcat,role1" /> 
</tomcat-users>
