解决tomcat一闪而过问题

  1. 环境:      jdk 1.8.0.91           windows2003           tomcat8.0
  2. 故障现象:启动tomcat 时, 一闪而过
  3. 排障步骤:  

      a) 首先是要调出错误信息:

                         i.  修改tomcat的bin目录下的启动文件startup.bat

          原内容如下:

          call "%EXECUTABLE%" start %CMD_LINE_ARGS%

          :end

      修改后如下:

          call "%EXECUTABLE%" run  %CMD_LINE_ARGS%

          :end

          pause

保存后启动tomcat

b)         得到如下错误信息:

24-Aug-2016 08:33:00.836 SEVERE [main] org.apache.tomcat.util.digester.Digester.

startElement Begin event threw exception

java.lang.ClassNotFoundException: org.apache.catalina.core.JasperListener

解决方法很简单:

         因为之前使用的tomcat7部署的, 现在升级到tomcat8. 但tomcat8的conf中的server.xml文件, 跟7中的略有不同. 只需要按照7中的端口号来更改8的server.xml文件即可

下面是tomcat自带的server.xml部分

<?xml version='1.0' encoding='utf-8'?>

<Server port="8005" shutdown="SHUTDOWN">

  <Listener className="org.apache.catalina.startup.VersionLoggerListener" />

  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />

  <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />

  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />

  <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />

    <Resource name="UserDatabase" auth="Container"

              type="org.apache.catalina.UserDatabase"

              description="User database that can be updated and saved"

              factory="org.apache.catalina.users.MemoryUserDatabaseFactory"

              pathname="conf/tomcat-users.xml" />

  </GlobalNamingResources>

  <Service name="Catalina">

接下来是tomcat7的server.xml部分

<?xml version='1.0' encoding='utf-8'?>

<Server port="8005" shutdown="SHUTDOWN">

  <Listener className="org.apache.catalina.startup.VersionLoggerListener" />

  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />

  <Listener className="org.apache.catalina.core.JasperListener" />  注释这行

  <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />

  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />

  <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />

    <Resource name="UserDatabase" auth="Container"

              type="org.apache.catalina.UserDatabase"

              description="User database that can be updated and saved"

              factory="org.apache.catalina.users.MemoryUserDatabaseFactory"

              pathname="conf/tomcat-users.xml" />

  </GlobalNamingResources>

c)第二种故障Exception in thread "main" java.lang.UnsupportedClassVersionError: org/apache/ca
talina/startup/Bootstrap : Unsupported major.minor version 51.0

JDK版本错误, 重新编译或者使用低版本的tomcat

 

最后不要忘记把startup.bat更改回来
