-------------------------------------------
Summary: blueprint-ext could support ${env:USER} notation (for OS
env variables)
Key: ARIES-1264
URL: https://issues.apache.org/jira/browse/ARIES-1264
Project: Aries
Issue Type: Improvement
Components: Blueprint
Reporter: Jean-Baptiste Onofré
Assignee: Jean-Baptiste Onofré
In a blueprint descriptor, it's possible to use blueprint-ext to use Java
System variable (the ones passed as argument using -Duser=$USER) and used with
something like:
{code}
<ext:property-placeholder placeholder-prefix="$[" placeholder-suffix="]"/>
...
<bean ...><property name="user" value="$[user]"/></bean>
{code}
In the org.apache.aries.blueprint.ext.PropertyPlaceholder, we do:
{code}
v = System.getProperty(val);
{code}
Additionnaly, it would be great to do System.getenv() to access the OS env
variables, and so being able to do:
{code}
<ext:property-placeholder placeholder-prefix="$[" placeholder-suffix="]"/>
...
<bean ...><property name="user" value="$[USER]"/></bean>
{code}
where USER has been set with something like this, for instance:
{code}
export USER=my
{code}
