基于SpringMVC国际化资源配置方式Demo

一.项目结构：



图
二.操作步骤：

在springmvc.xml配置如下内容

1.配置拦截器

<!-- 本地化变更拦截器 -->
<bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" />

<mvc:interceptors>
<!-- 国际化资源切换时，根据请求参数中的locale参数自动切换 -->
<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进行切换的话选用Session方式，如果要是浏览器自适应语言的话可以选用cookies方式。

<!-- 浏览器自适应语言方式（cookie方式） -->
<!-- <bean id="cookieLocaleResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver" /> -->

<!-- 需要在界面上进行切换（session方式） -->
<bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver">
<!-- 会话属性不存在,默认属性设置 -->
<property name="defaultLocale" value="zh_CN" />
</bean>

3.配置资源文件读取

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

4.将message_en_US.properties和message_zh_CN.properties放到项目的类路径下。

三.示例演示：

springmvc.xml

<context:component-scan base-package="com.dqiang"></context:component-scan>
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
p:prefix="/WEB-INF/views/" p:suffix=".jsp"></bean>

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

<!-- 本地化变更拦截器 -->
<bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" />

<!-- 浏览器自适应语言方式（cookie方式） -->

<bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver">
<!-- 会话属性不存在,默认属性设置 -->

</bean>

<mvc:interceptors>
<!-- 国际化资源切换时，根据请求参数中的locale参数自动切换 -->
<mvc:interceptor>
<mvc:mapping path="/**" />
<ref bean="localeChangeInterceptor" />
</mvc:interceptor>
</mvc:interceptors></beans>
