请求的资源上没有“Access-Control-Allow-Origin”标头。响应的HTTP状态代码为401

Question

我正在使用angular$HTTP调用一个cross doamin REST Web服务（Spring）。请在下面找到代码。

$http({    
url: ' http://xxx.yyy.zzz:8080/..../sponsors',
method: 'GET',
   headers: {  'Token' : 'abc'  }
}).success(function(sponsors){
      $scope.sponsorList = sponsors;
}).error(function(sponsors){
       alert('failed to get sponsors')
});

我得到以下错误

<filter>
  <filter-name>CorsFilter</filter-name>
  <filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
</filter>
<filter-mapping>
  <filter-name>CorsFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

谁能帮我修一下这个吗？我在客户端错过了任何头球吗？还需要在服务器端做什么？

提前致谢
