基於SpringMVC國際化資源配置方式Demo

一.項目結構：

圖

二.操作步驟：

在springmvc.xml配置如下內容

1.配置攔截器

<!-- 本地化變更攔截器 -->
<bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" />

<mvc:interceptors>
<!-- 國際化資源切換時，根據請求參數中的locale參數自動切換 -->
<mvc:interceptor>
<mvc:mapping path="/**" />
<ref bean="localeChangeInterceptor" />
</mvc:interceptor>
</mvc:interceptors>

2.配置解析方式

如果是需要在界面上進行切換的話選用Session方式，如果要是瀏覽器自適應語言的話可以選用cookies方式。

<!-- 瀏覽器自適應語言方式（cookie方式） -->
<!-- <bean id="cookieLocaleResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver" /> -->
	
<!-- 需要在界面上進行切換（session方式） -->
<bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver">
	<!-- 會話屬性不存在,默認屬性設置 -->
	<property name="defaultLocale" value="zh_CN" />
</bean>

3.配置資源文件讀取

<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
	<property name="basename" value="message" />
	<property name="useCodeAsDefaultMessage" value="true" />
</bean>

4.將message_en_US.properties和message_zh_CN.properties放到項目的類路徑下。

三.示例演示：

springmvc.xml

	<mvc:interceptors>
		<!-- 國際化資源切換時，根據請求參數中的locale參數自動切換 -->
		<mvc:interceptor>
			<mvc:mapping path="/**" />
			<ref bean="localeChangeInterceptor" />
		</mvc:interceptor>
	</mvc:interceptors>
</beans>
