Question

I would like to import different resource files based on some condition. Is this possible?

These don’t work:

<import resource="#{ systemProperties['foo'] }.xml" /> 

<import resource="#{ T(my.testpkg).getValue() }.xml" /> 

Answer 1

SpEL is supported, but Spring resolves the import statement very early on.

When spring is resolving import statements, property placeholders have not yet been resolved.

For example:

Define the following properties:

import.fileName=${blah}
blah=properties.props

We can then use the ‘import.fileName’ property as a parameter to the import

<import resource="${import.fileName}" />

This resolves to:

<import resource="${blah}" />

And presumably the resource ‘${blah}’ does not exist.

That being said, you can use properties to resolve import file names.
