Format可能存在的坑

import java.text.MessageFormat;


public class TestFormat {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        String str = MessageFormat.format("/status={0}&app={1}&version={2}", new Object[] { 123, 1234, 12345 });
        
        System.out.println(str);
        
        String str2 = String.format("/status=%s&app=%s&version=%s", "123","1234","12345");
        System.out.println(str2);
    }

}
