Spring的i18n配置:
<!-- conf:i18n  -->
<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
<property name="fallbackToSystemLocale" value="false" />
<property name="useCodeAsDefaultMessage" value="true" />
<property name="defaultEncoding" value="UTF-8" />
<property name="cacheSeconds" value="60" />
<property name="basenames">
<list>
<value>classpath:com/hupu/nac/i18n/message</value>
</list>
</property>
</bean>

Spring的i18n使用:
