Tomcat | SEVERE: Error listenerStart

       版本说明：

操作系统：CentOS 6.6 x64

JDK：1.7.0_55

Tomcat：7

       问题描述：

       迁移Tomcat工程启动后日志出现报错，内容如下：

 

Jan 20, 2018 7:02:50 PM org.apache.catalina.core.StandardContext startInternal
SEVERE: Error listenerStart
Jan 20, 2018 7:02:49 PM org.apache.catalina.core.StandardContext startInternal
SEVERE: Context [] startup failed due to previous errors
Jan 20, 2018 7:02:49 PM org.apache.coyote.AbstractProtocol start
INFO: Starting ProtocolHandler ["http-bio-8680"]
Jan 20, 2018 7:02:49 PM org.apache.catalina.startup.Catalina start
INFO: Server startup in 30535 ms

 

       从以上内容中并不能获得到关键信息，其中只提示了有错误存在却没有说明故障点，此时需要修改日志级别来打印更多的信息来帮助我们排错，方法如下。

       解决方案：

       在tomcat工程中的classes路径下，在文件logging.properties中添加如下内容，如没有该文件则直接创建。

 

handlers = org.apache.juli.FileHandler, java.util.logging.ConsoleHandler  
org.apache.juli.FileHandler.level = FINE  
org.apache.juli.FileHandler.directory = ${catalina.base}/logs  
org.apache.juli.FileHandler.prefix = error-debug.   
java.util.logging.ConsoleHandler.level = FINE  
java.util.logging.ConsoleHandler.formatter=java.util.logging.SimpleFormatter

 

       接下来重启Tomcat，然后再查看日志，我所遇到的问题如下：

 

Jan 20, 2018 7:07:20 PM org.apache.catalina.core.StandardContext listenerStart
SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

       通过以上信息确认问题是出现在数据库连接上，将连接信息重新修改后重启Tomcat，“SEVERE: Error listenerStart”没有再次出现。

       总结：

　　以上介绍了在排错中可以通过修改Tomcat日志级别的方式来获取更多的日志信息，进而帮助我们排错，而具体的问题就要结合实际情况去确认，并非导致“SEVERE: Error listenerStart”的原因都一致。
