[Tomcat報錯]SEVERE: Error listenerStart

系統版本：CentOS 6.6 x64

java版本：1.7.0_55

 

問題描述：

遷移Tomcat工程啓動後日志出現報錯，內容以下：

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

從以上內容中並不能得到到關鍵信息，其中只提示了有錯誤存在卻沒有說明故障點，此時須要修改日誌級別來打印更多的信息來幫助咱們排錯，方法以下。

 

解決方案：

在tomcat工程中的classes路徑下，在文件logging.properties中添加以下內容，如沒有該文件則直接建立。

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

接下來重啓Tomcat，而後再查看日誌，我所遇到的問題以下：

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

經過以上信息確認問題是出如今數據庫鏈接上，將鏈接信息從新修改後重啓Tomcat，「SEVERE: Error listenerStart」沒有再次出現。

 

總結：

　　以上介紹了在排錯中能夠經過修改Tomcat日誌級別的方式來獲取更多的日誌信息，進而幫助咱們排錯，而具體的問題就要結合實際狀況去確認，並不是致使「SEVERE: Error listenerStart」的緣由都一致。
