新建两个国际化资源文件

resource\_en\_US.properties

resource\_zh\_CN.properties

格式：资源文件的名称\_<语言>\_<国家>.properties

resource_en_US.properties
    name=I am {0},today is {1} year!
    
    resource_zh_CN.properties
    name=\u6211\u53EB{0},\u4ECA\u5929{1}\u5E74!

配置applicationContext.xml

<bean id="resource" class="org.springframework.context.support.ResourceBundleMessageSource">
    	 	<property name="basenames">
    	 		<list>
    	 			<value>resource</value>
    	 		</list>
    	 	</property>
    	 	<property name="cacheSeconds" value="5"></property>
    	 </bean>

测试类：

package com.ioc;
    
    import java.text.DecimalFormat;
    import java.text.MessageFormat;
    import java.text.SimpleDateFormat;
    import java.util.Date;
    import java.util.Locale;
    import java.util.ResourceBundle;
    
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    import org.springframework.context.support.ResourceBundleMessageSource;
    
    public class ResourceUtil {
    
    	public static void main(String[] args) {
    		//时间格式化
    		String datestring = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss:sss").format(new Date());
    		System.out.println(datestring);
    		//数字格式化
    		String num = new DecimalFormat("0.000").format(12.34534);
    		System.out.println(num);
    		//JDK自带的国际化
    		//统一使用一个资源文件进行管理.
    		//名称必须:资源文件的名称_<语言>_<国家>.properties
    		//如资源文件不在classpath，ResourceBundle.getBundle("com/ioc/resource",Locale.CHINA);
    		ResourceBundle resourceBundle = ResourceBundle.getBundle("resource",Locale.US);
    		ResourceBundle resourceBundle1 = ResourceBundle.getBundle("resource",Locale.CHINA);
    		
    		Object[] params = {"MM",2016};
    		String str1 = new MessageFormat(resourceBundle.getString("name")).format(params);
    		String str2 = new MessageFormat(resourceBundle1.getString("name")).format(params);
    		
    		System.out.println(str1);
    		System.out.println(str2);
    		
    		//spring 国际化
    		//加载资源文件---获取资源文件中的内容----替换数据
    		ApplicationContext context = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
    		ResourceBundleMessageSource resourceBundleMessageSource = (ResourceBundleMessageSource) context.getBean("resource");
    		String str3 = resourceBundleMessageSource.getMessage("name", params, Locale.US);
    		String str4 = resourceBundleMessageSource.getMessage("name", params, Locale.CHINA);
    		System.out.println(str3);
    		System.out.println(str4);
    		
    	}
    }

结果：

2016-12-16 15:29:07:007
    12.345
    I am MM,today is 2,016 year!
    我叫MM,今天2,016年!
