PathMatchingResourcePatternResolver is not able to resolve file in SpringBoot Packaged JAR

[pawank94]

Referring to #34126.

@jhoeller, sorry for replying so late. But this issue is still not fixed. Changes done in

spring-framework/spring-core/src/main/java/org/springframework/core/io/support/PathMatchingResourcePatternResolver.java

Line 937 in 9975113

Iterator<String> entryIterator = jarFile.stream().map(JarEntry::getName).sorted().iterator();

still doesn't fix the problem that BOOT-INFO is part of prefix.

you can test this code by taking a spring-boot-maven-plugin generated JAR file and checking output of these commands in a debugger

StreamSupport.stream(Spliterators.spliteratorUnknownSize(jarFile.entries().asIterator(), 0), false ).collect(Collectors.toList())

and

jarFile.stream().map(JarEntry::getName).collect(Collectors.toList())

jarFile.stream() generated path had an extra BOOT-INFO/ prefix.

Can you please check this again? We will be prompt this time for any other question or validations.

I ended up with a different change: based on JarFile#entries() like in 6.1.x and using the entries cache TreeSet that we got there already for sorting, before we iterate over that sorted set then for identifying matching entries. The advantage with that variant is that we don't need to check for a Boot-specific prefix, and we can even remove the jar separator check as well.

This will available in the upcoming 6.2.12 snapshot in a few minutes. Please give it a try at your earliest convenience!
