实现接口ApplicationContextAware  
说明：实现该接口的setApplicationContext(ApplicationContext context)方法，并保存ApplicationContext 对象。  
Spring初始化时，会通过该方法将ApplicationContext对象注入。

import java.util.Locale;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.ApplicationContextAware;
    import org.springframework.context.NoSuchMessageException;
    
    public class GnericUtils implements ApplicationContextAware {
        private static ApplicationContext applicationContext;
    
        public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
            applicationContext = applicationContext;
        }
    
        public static String getMessage(String code) {
            return getMessage(code, (Object[])null, (Locale)null);
        }
    
        public static String getMessage(String code, String defaultMessage) {
            return getMessage(code, (Object[])null, defaultMessage, (Locale)null);
        }
    
        public static String getMessage(String code, Object[] args) {
            return getMessage(code, args, (Locale)null);
        }
    
        public static String getMessage(String code, Object[] args, String defaultMessage, Locale locale) {
            return applicationContext.getMessage(code, args, defaultMessage, locale);
        }
    
        public static String getMessage(String code, Object[] args, Locale locale) throws NoSuchMessageException {
            return applicationContext.getMessage(code, args, locale);
        }
    }

以上方法需要在xml文件中配置bean。
