Spring 部署war时的HTTP状态[500]-Servlet.init（）

我想将war部署到tomcat8，但调用url时：

获取错误：

HTTP状态[500]–[内部服务器错误]

javax.servlet.ServletException:servlet的servlet.init（） [dispatchers]引发异常 org.apache.catalina.authenticator.AuthenticatorBase.invoke（AuthenticatorBase.java:478） org.apache.catalina.valves.ErrorReportValve.invoke（ErrorReportValve.java:80） org.apache.catalina.valves.AbstractAccessLogValve.invoke（AbstractAccessLogValve.java:624） org.apache.catalina.connector.CoyoteAdapter.service（CoyoteAdapter.java:342） org.apache.coyote.http11.Http11Processor.service（Http11Processor.java:799） org.apache.coyote.AbstractProcessorLight.process（AbstractProcessorLight.java:66） org.apache.coyote.AbstractProtocol$ConnectionHandler.process（AbstractProtocol.java:861） org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun（NioEndpoint.java:1455） org.apache.tomcat.util.net.SocketProcessorBase.run（SocketProcessorBase.java:49） java.util.concurrent.ThreadPoolExecutor.runWorker（未知源） java.util.concurrent.ThreadPoolExecutor$Worker.run（未知源） org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run（TaskThread.java:61） java.lang.Thread.run（未知源）

在部署之前，我通常使用maven build运行项目，这个url正在运行。为什么不在部署后运行
