java - Tomcat7 CentOS 服务启动失败

Question

我在自动加载 tomcat7 时遇到问题。这是 init.d 脚本:

#!/bin/bash
# chkconfig: 2345 80 20
# Description: Tomcat Server basic start/shutdown script
# /etc/init.d/tomcat7 -- startup script for the Tomcat 7 servlet engine

TOMCAT_HOME=/usr/local/tomcat7/bin
START_TOMCAT=/usr/local/tomcat7/bin/startup.sh
STOP_TOMCAT=/usr/local/tomcat7/bin/shutdown.sh

start() {
 echo -n "Starting tomcat7: "
 cd $TOMCAT_HOME
 ${START_TOMCAT}
 echo "done."
}

stop() {
 echo -n "Shutting down tomcat7: "
 cd $TOMCAT_HOME
 ${STOP_TOMCAT}
 echo "done."
}

case "$1" in

start)
 start
 ;;

stop)
 stop
 ;;

restart)
 stop
 sleep 10
 start
 ;;

*)
 echo "Usage: $0 {start|stop|restart}"

esac
exit 0

像这样开始时:

>service tomcat7 start

Starting tomcat7: 
Using CATALINA_BASE:   /usr/local/tomcat7
Using CATALINA_HOME:   /usr/local/tomcat7
Using CATALINA_TMPDIR: /usr/local/tomcat7/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /usr/local/tomcat7/bin/bootstrap.jar:/usr/local/tomcat7/bin/tomcat-juli.jar
Tomcat started.
done.

Tomcat 似乎无法从 apache commons 加载属性文件。有谁知道这是为什么？

The file is:
user-config.properties
found in:
/usr/local/tomcat7/conf

像这样直接运行一切正常:

/usr/local/tomcat7/bin/startup.sh 
Using CATALINA_BASE:   /usr/local/tomcat7
Using CATALINA_HOME:   /usr/local/tomcat7
Using CATALINA_TMPDIR: /usr/local/tomcat7/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /usr/local/tomcat7/bin/bootstrap.jar:/usr/local/tomcat7/bin/tomcat-juli.jar
Tomcat started.

贯穿:

%>服务tomcat7启动启动 tomcat7:使用 CATALINA_BASE:/usr/local/tomcat7使用 CATALINA_HOME:/usr/local/tomcat7使用 CATALINA_TMPDIR:/usr/local/tomcat7/temp使用 JRE_HOME:/usr使用类路径:/usr/local/tomcat7/bin/bootstrap.jar:/usr/local/tomcat7/bin/tomcat-juli.jar Tomcat 启动。完成。

现在我加载导致错误的网页

在您自己的代码中看起来像一个 NPE:

java.lang.NullPointerException
