如何在应用上下文中读取系统环境变量?
How to read the system environment variable in the application context?
我想要类似的东西:
<util:properties id="dbProperties"
location="classpath:config_DEV/db.properties" />
或
<util:properties id="dbProperties"
location="classpath:config_QA/db.properties" />
取决于环境.
我的应用程序上下文中可以有这样的东西吗?
Can I have something like this in my application Context?
<util:properties id="dbProperties"
location="classpath:config_${systemProperties.env}/db.properties" />
根据系统环境变量设置实际值

查看这篇文章.它通过 PropertyPlaceholderConfigurer
支持外部属性(通过 systemPropertiesMode
属性).
Check this article. It gives you several ways to do this, via the PropertyPlaceholderConfigurer
which supports external properties (via the systemPropertiesMode
property).
