Improve property placeholder resolution when multiple configurers are declared [SPR-10654]

[spring-projects-issues]

Bozhidar Bozhanov opened SPR-10654 and commented

There are some problems when working with multiple <context:property-placeholder /> are defined (possibly in multiple .xml files)

• when there are more than one configurers, the "ignore-unresolved" must be set to "true", otherwise startup fails, because one configurer doesn't have all the required properties

• if there are nested properties obtained from multiple locations, startup fails, because ignore-unresolved does not affect the ignoreUnresolvableNestedPlaceholders property.

Here are some more details on my current issue: http://stackoverflow.com/questions/17084563/spring-namespacehandler-and-multiple-property-placeholders

Currently it is solved by setting env.setIgnoreUnresolvableNestedPlaceholders(true), but I think there should be available for configuration via tha *PlaceholderConfigurer. Currently it is a property of the PropertyResolver and is not accessible from anywhere, apart from the Environment

This looks like it might possibly be a duplicate of #14623?
