Question

我正在与这一整天打架：我想从AuthentificationService调用connect服务方法我有这个例外（底部的其余代码）：

我的AngularJS服务：

cmlAppModule.factory('AuthentificationService', function ($resource) {

    return $resource('rest/authentificationService/:path',
            {path: '@path'},
    {
        disconnect: {
            method: 'GET',
            params: {
                path: "disconnect"
            }
        },
        isConnected: {
            method: 'GET',
            params: {
                path: "isConnected"
            }
        },
        connect: {
            method: 'GET',
            params: {
                path: "connect"
            }
        }
    });
});

请问是否有人可以帮助我并为此提供可能的解决方案..

谢谢，

在如此多的层面上有太多错误

没有＆＃34; Authentification＆＃34;这样的词。它＆＃34;认证＆＃34; ： - ）
@ApplicationPath应该在应用程序配置类上使用，而不是在资源类上使用。例如
```
@ApplicationPath("/rest")
public class AppConfig extends PackagesConfig {
    public AppConfig() {
        super("the.packages.to.scan.for.resources.and.provders");
    }
}
```
有了这个，您可以摆脱我们的web.xml（或者至少是您尝试过的servlet配置）。这几乎完全相同。将包名称更改为资源包。并从资源类中删除@ApplicationPath。
在您的web.xml中，您无法
```
<servlet>
    <servlet-name>AuthentificationService</servlet-name>
    <servlet-class>
        net.iots.iotshub.web.service.AuthentificationService
    </servlet-class>
</servlet>
```
除非AuthentificationService是一个真正的Servlet（我无法告诉我，因为我不知道AbstractService是什么。无论如何，即使它是，这个配置仍然不会工作。

servlet分配中的异常
