Java / Regex-匹配所有内容，直到下次匹配

Question

How do I match everything till the next match with Java/Regex ? For example, I have the string:

"Check the @weather in new york and @order me a pizza"

I want to get two matches:

1. @weather in new york and
2. @order me a pizza

I attempted following: @.+@ but it selects the @ symbol from next match as well.

Maybe, this simple expression might be close to what you have in mind:

@[^@]*

Test

import java.util.regex.Matcher;
import java.util.regex.Pattern;


public class re{
    public static void main(String[] args){
        final String regex = "@[^@]*";
        final String string = "Check the @weather in new york and @order me a pizza";

        final Pattern pattern = Pattern.compile(regex);
        final Matcher matcher = pattern.matcher(string);

        while (matcher.find()) {
            System.out.println("Full match: " + matcher.group(0));
            for (int i = 1; i <= matcher.groupCount(); i++) {
                System.out.println("Group " + i + ": " + matcher.group(i));
            }
        }


    }
}

Output

Full match: @weather in new york and 
Full match: @order me a pizza
