Load a properties file from a path specified in environment variable in spring

Question

Hello I am new to Spring so please forgive me if its a silly question.

I need to load a properties file from a path specified in the environment variables, For example, my environment variable will contain a pah to a folder - MY_ENV=D:\abc. And in this directory i will have my .properties file.

Thanks

Just enclose the property in ${}:

<ctx:property-placeholder location="file:${MY_ENV}/yourfile.properties"/>

what if you declare your env property like this: MY_ENV=d:/abc i.e. : / instead of \ – Frederic Close Nov 06 '13 at 18:30

You can use SpEL to load environment variables into your configs:

<bean id="someBean" class="com.mypackage.SomeClass">
    <property name="somePropertiesPath" value="#{environment['MY_ENV']}/my.properties" />
</bean>

I don't know if you were looking to use your properties as a PropertyPlaceholderConfigurer or just as another Properties bean, so if you clarify that point, I can give you the exact xml you need.
