is SpEL supported in import statements?

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" />
Solution

  • 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.
