聽衆類未找到

我正在開發一個maven項目。已在tomcat7一個監聽器類，但是當我部署我得到以下錯誤：聽衆類未找到

監聽器類

public class DBInitialisationListener implements ServletContextListener { 

public void contextInitialized(ServletContextEvent event) { 

    System.out.println("Db Initialised"); 
} 

public void contextDestroyed(ServletContextEvent event) { 
    DatabaseFactory.close(); 
    System.out.println("Db Closed"); 
} 
}

的web.xml

<listener> 
     <listener-class>com/nrift/ovmgmt/core/DBInitialisationListener</listener-class> 
</listener>

您必須指出軟件包類別爲definde，我的意思是，帶點「。」。

<listener> 
     <listener-class>com.nrift.ovmgmt.core.DBInitialisationListener</listener-class> 
</listener>

這是因爲Maven的沒有找到類

要檢查類已<listener-class>標籤正確添加的原因，嘗試喲做出CTRL+Click在類

類名是偵聽器配置不正確。使用如下。

<listener> 
    <listener-class>com.nrift.ovmgmt.core.DBInitialisationListener</listener-class> 
</listener>
