项目执行maven build，然后控制台里tomcat日志打印到一半就停了，也没有报错：

八月 18, 2017 4:26:06 下午 org.apache.coyote.AbstractProtocol init

信息: Initializing ProtocolHandler ["http-bio-8080"]

八月 18, 2017 4:26:06 下午 org.apache.catalina.core.StandardService startInternal

信息: Starting service Tomcat

八月 18, 2017 4:26:06 下午 org.apache.catalina.core.StandardEngine startInternal

信息: Starting Servlet Engine: Apache Tomcat/7.0.47

八月 18, 2017 4:26:39 下午 org.apache.catalina.core.ApplicationContext log

信息: No Spring WebApplicationInitializer types detected on classpath

八月 18, 2017 4:26:44 下午 org.apache.catalina.core.ApplicationContext log

信息: Initializing Spring FrameworkServlet 'e3-manager'

然后在项目里加了两处log4j.properties文件，除了一些正常debug信息外最后打印出如下错误信息，看不太明白，百度也没找到解决办法，求指教
