Spring ApplicationContext的国际化乱码

按书上进行对ApplicationContext国际化进行试验，可是我依旧是乱码

public class SpringTest {
    public static void main(String[]args)throws Exception{
        ApplicationContext ctx=
                new ClassPathXmlApplicationContext("beans.xml");
        String hello=ctx.getMessage
                ("hello", new String[]{"打"}, 
                        Locale.getDefault(Locale.Category.FORMAT));
        String welcome=ctx.getMessage
                ("now", new Date[]{new Date()}, 
                        Locale.getDefault(Locale.Category.FORMAT));
        System.out.println(hello);
        System.out.println(welcome);
    }
}
