Tomcat - 如何指定可以在 server.xml 中扩展的属性

Question

目前，我的 server.xml 中有:

<Connector port="8080" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" />

我希望它变成:

<Connector port="${oms.ui.port}" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" />

我将此属性 oms.ui.port 放在驻留在 apache-tomcat-7.0.8\lib 中的属性文件中但它没有找到它，我得到:

WARNING: [SetAllPropertiesRule]{Server/Service/Connector} Setting property 'port' to '${oms.ui.port}' did not find a matching property.

也许有更好的 Tomcat 经验的人可以帮助我，好吗？

根据 Tomcat 7.0 Configuration Overview :

Apache Ant-style variable substitution is supported; a system property with the name propname may be used in a configuration file using the syntax ${propname}. All system properties are available including those set using the -D syntax, those automatically made available by the JVM and those configured in the $CATALINA_BASE/conf/catalina.properties file.

因此，您可以使用 JVM 系统属性或 catalina.properties 来声明您的变量并为其赋值。
