spring的xml配置文件 commonBean.xml--国际化

<bean id="crm.messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
	<property name="basenames">
		<list>
			<value>crm.baseConfig.crmErrorCodes</value>
		</list>
	</property>
</bean>
---------------------------------------------------------------------------------
中文错误码配置文件
crmErrorCodes_zh_CN.properties
英文错误码配置文件
crmErrorCodes_en_US.properties
---------------------------------------------------------------------------------
使用：
String msg = DemoResourceBundle.getMessage(e.getCode(), e.getTextMessage());
