我正在尝试将 Guice 4.0 用于 Tomcat 8 的 Web 应用程序。我尝试从 wiki 做示例，但我在 Tomcat Localhost 日志中收到此错误:
28-Nov-2015 16:36:26.136 SEVERE [RMI TCP Connection(3)-127.0.0.1] org.apache.catalina.core.StandardContext.listenerStart Error configuring application listener of class com.nirus.guice_confige.MyGuiceServletConfig

...
这是我的 web.xml 文件:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"

<filter-name>guiceFilter</filter-name>
<filter-class>com.google.inject.servlet.GuiceFilter</filter-class>

</filter-mapping>
<listener>

</listener>
</web-app>
还有我的 Guice 配置文件:
public class MyGuiceServletConfig extends GuiceServletContextListener {
@Override
protected Injector getInjector() {
return Guice.createInjector(new ServletModule(){
@Override
protected void configureServlets() {
serve("/JoinLobby").with(JoinLobby.class);
serve("/UpdateLobby").with(UpdateLobby.class);
bind(ILobby.class).to(Lobby.class);
}
});
}
}
UPD1: 这是我的 Maven pom.xml 文件
