Spring之i18n配置与使用

Posted 2022-12-12 Joyce-Luo

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：

import java.util.Locale;
