Spring reading properties from application.properties file with wildcard

Question

I would like to read an array of proprieties from application.properties in spring with a wildcard.

For example I have this properties:

file.processing.xpath.query.1=query1
file.processing.xpath.query.2=query2

and then I would like to get the properties in an array or in a list like this

 @Value("${file.processing.xpath.query.*}")
    private String[] xpathQuery;

is there a way to do this?

when I try to do it like this I receive an exception

Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'file.processing.xpath.query' in string value "${file.processing.xpath.query.*}"

You have to define your properties like this:

file.processing.xpath.query=query1,query2,query3

And then use:

@Value("${file.processing.xpath.query}")
    private String[] xpathQuery;
