       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

    at java.lang.Thread.run(Thread.java:745)

       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。
