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。有人知道为什么是这样吗 ？
The file is:
user-config.properties
found in:
/usr/local/tomcat7/conf
直接运行时一切正常，如下所示：
/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.
跑过，匆匆处理：
％>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CLASSPATH：/usr/local/tomcat7/bin/bootstrap.jar:/usr/local/tomcat7/bin/tomcat-juli.jar
Tomcat启动。
完成。

最佳答案
在您自己的代码中看起来像NPE：
root cause
java.lang.NullPointerException
java.lang.String.replace(String.java:2180)
com.ftw.tme.commons.db.util.tmeConfigUtils.<clinit>(tmeConfigUtils.java:71)
com.ftw.tme.authentication.service.impl.AuthenticationServiceImpl.<init>(AuthenticationServiceImpl.java:27)
com.ftw.tme.rest.AuthenticationRestService.<init>(AuthenticationRestService.java:38)
