Regex inverse matching on specific string?
I would like to match the following
- com.my.company.moduleA.MyC开发者_开发问答lassName
- com.my.company.moduleB.MyClassName
- com.my.company.anythingElse.MyClassName
but not the following
- com.my.company.core.MyClassName
My current simple regex pattern is :
Pattern PATTERN_MODULE_NAME = Pattern.compile("com\\.my\\.company\\.(.*?)\\..*")
Matcher matcher = PATTERN_MODULE_NAME.matcher(className);
if (matcher.matches()) {
// will return the string inside the parentheses (.*?)
return matcher.group(1);
}
So, basically, how can i match everything else, but not a specific string, which is the string core in my case.
Please share your ideas on how to achieve that in Java ?
Thank you !
You can use the following regex:
^com\\.my\\.company\\.(?!core).+?\\.MyClassName$
Perhaps a regex is not the clearest way to write this.
if (className.startsWith("com.my.company.")
&& !className.startsWith("com.my.company.core.")) {
}
This is fair clear what it does, and you might find it is faster. ;)
