从 Spring 4.x 升级到 5.x 时出现“InvalidPathException: Illegal char <*>”

Question

I am trying to upgrade from Spring 4.x to Spring 5.x but facing one issue. I have multiple spring xml configuration files in META-INF\spring\abc\ directory. In META-INF\spring\ directory I have abc-context.xml file which contains following line:

<!-- Spring Bean Profiles will ensure only one instance is loaded based on -Dinstance=[name] -->
<import resource="abc/*.xml"/>

When I run the application with Spring 4.x everything works fine. Excerpt from the logs:

DEBUG PathMatchingResourcePatternResolver - Looking for matching resources in directory tree [C:\...\abc\target\classes\META-INF\spring\abc]
DEBUG PathMatchingResourcePatternResolver - Searching directory [C:\...\abc\target\classes\META-INF\spring\abc] for files matching pattern [.../abc/target/classes/META-INF/spring/abc/*.xml]
DEBUG PathMatchingResourcePatternResolver - Resolved location pattern [file:.../abc/target/classes/META-INF/spring/abc/*.xml] to resources [file [C:\...\abc\target\classes\META-INF\spring\abc\pqr.xml], file [C:\...\abc\target\classes\META-INF\spring\abc\mno.xml], file [C:\...\abc\target\classes\META-INF\spring\abc\xyz.xml]]

When I upgrade to Spring 5.x and try to run the application, I get following exception:

Exception in thread "main" org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from file [...\target\classes\META-INF\spring\abc-context.xml]; nested exception is java.nio.file.InvalidPathException: Illegal char <*> at index 88: ...\target\classes\META-INF\spring\abc\*.xml

Can someone please help me understand why * is getting treated as illegal character here? Any solution?

PS: I know I can have multiple bean profile definitions and import the files accordingly but I do not want to do that because it would be an additional change for me in many (200+) applications.

Answer 1

I have got the solution.

changing this

<import resource="abc/*.xml"/>

to this

<import resource="classpath:META-INF/spring/abc/*.xml"/>

solves the issue.
