### Descriptions

I hope to modify the resolvePackagesToScan function in the ServiceAnnotationPostProcessor class information to

private Set resolvePackagesToScan(Set packagesToScan) {
Set resolvedPackagesToScan = new LinkedHashSet<>(packagesToScan.size());
for (String packageToScan : packagesToScan) {
if (StringUtils.hasText(packageToScan)) {
String resolvedPackageToScan = environment.resolvePlaceholders(packageToScan.trim());
resolvedPackageToScan=resolvedPackageToScan.replace(",",";");
resolvedPackageToScan=resolvedPackageToScan.replace("\t",";");
resolvedPackagesToScan.addAll(Arrays.asList(resolvedPackageToScan.split(";")));
}
}
return resolvedPackagesToScan;
}

Start by locating ServiceAnnotationPostProcessor and its resolvePackagesToScan function in the Apache Dubbo Java SDK. Review how package values are currently resolved and separated, then verify handling of the comma- and tab-separated inputs shown in the issue. Done means the function returns the intended package set without losing resolved entries.
