今天啟動tomcat的時候出現了這樣的錯誤

java.lang.AbstractMethodError: javax.servlet.jsp.JspFactory.getJspApplicationContext(Ljavax/servlet/ServletContext;)Ljavax/servlet/jsp/JspApplicationContext;

報錯源碼

嚴重: Servlet.service() for servlet [jsp] in context with path [/user_04] threw exception [java.lang.AbstractMethodError: javax.servlet.jsp.JspFactory.getJspApplicationContext(Ljavax/servlet/ServletContext;)Ljavax/servlet/jsp/JspApplicationContext;] with root cause java.lang.AbstractMethodError: javax.servlet.jsp.JspFactory.getJspApplicationContext(Ljavax/servlet/ServletContext;)Ljavax/servlet/jsp/JspApplicationContext;at org.apache.jasper.compiler.Validator$ValidateVisitor.<init>(Validator.java:521)at org.apache.jasper.compiler.Validator.validateExDirectives(Validator.java:1846)at org.apache.jasper.compiler.Compiler.generateJava(Compiler.java:218)at org.apache.jasper.compiler.Compiler.compile(Compiler.java:374)at org.apache.jasper.compiler.Compiler.compile(Compiler.java:354)at org.apache.jasper.compiler.Compiler.compile(Compiler.java:341)at org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:660)at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:395)at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:395)at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:339)at javax.servlet.http.HttpServlet.service(HttpServlet.java:731)at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:303)at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:208)at org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:241)at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:208)at org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter.doFilter(StrutsPrepareAndExecuteFilter.java:88)at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:241)at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:208)at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:219)at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:110)at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:494)at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:169)at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:104)at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:1025)at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:116)at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:445)at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1137)at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:637)at org.apache.tomcat.util.net.AprEndpoint$SocketProcessor.doRun(AprEndpoint.java:2575)at org.apache.tomcat.util.net.AprEndpoint$SocketProcessor.run(AprEndpoint.java:2564)at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145)at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615)at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61)at java.lang.Thread.run(Thread.java:744)

網上說jar沖突，但是我的項目里面的lib下只有一個數據庫的驅動包，其他的jar包沒有，并沒有找到與tomcat沖突的jar包

現在唯一解決的辦法就是換一個Tomcat重新部署
