Question

我正在尝试在我的tomcat服务器上实现Log4J日志记录（我们在本地环境中实现了这一点，并且我准备将我们的服务迁移到AWS）。我跟随instructions found in the Tomcat7 documentation并将所有内容都放在合适的位置。当我尝试启动Tomcat时，我在日志中收到FileNotFound异常，应用程序无法启动。

我怀疑这是因为我们的Tomcat7配置存在一些非标准的问题，但AWS上的初始设置是由我不再可用的顾问执行的。我在哪里可以查看，我应该检查什么来纠正这个问题？

好的答案不应该指示我将logging.properties文件放在/usr/share/tomcat7/conf/中，因为这不是我现有配置的工作原理（我在那里没有这个问题）和tomcat7文档明确告诉用户从logging.properties 中删除../conf/，除非有一些警告需要它在tomcat文档中没有表达。

Answer 1

似乎问题与tomcat7 bash shell脚本（由上述顾问编写或更新）有关。此脚本已硬编码以检查Java选项（logging.properties）中的-Djava.util.logging.config.file="${CATALINA_BASE}/conf/logging.properties"文件。

从tomcat7脚本中删除此行已更正此问题。

为什么我收到此FileNotFoundException以及如何解决它？
