--------------------------------------
Summary: Support for nested property placeholders
Key: ARIES-1601
URL: https://issues.apache.org/jira/browse/ARIES-1601
Project: Aries
Issue Type: Improvement
Components: Blueprint
Reporter: Luca Burgazzoli
As today property placeholders are resolved sequentially but it would be nice
to have the possibility to resolve nested placeholders like:
{code}
${jre-${java.specification.version}}
{code}
The problem in blueprint seems to be located in
[AbstractPropertyPlaceholder|https://github.com/apache/aries/blob/trunk/blueprint/blueprint-core/src/main/java/org/apache/aries/blueprint/ext/AbstractPropertyPlaceholder.java#L429-L455]
I've been using StrSubstitutor from Commons-Lang and could be ported to
blueprint-ext.
See:
