/**
* SpringMVC 超链接国际化
*
* 1、在SpringMVC中配置 SessionLocaleResolver 的Bean
* <bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver"></bean>
* 需要写上id，不写则会报错，可能SpringMVC源码用到，有空再研究SpringMVC
* 2、在SpringMVC中配置 LocaleChangeInterceptor 的拦截器Interceptor
* org.springframework.web.servlet.i18n.LocaleChangeInterceptor
* 3、url通过带参locale=zh_CN/locale=en_US
* 则会读取properties中的翻译文件
*
*

测试类：

package com.spring.test;import java.util.Locale;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.support.ResourceBundleMessageSource;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controllerpublic class TestController {/** * SpringMVC 超链接国际化 *  * 1、在SpringMVC中配置 SessionLocaleResolver 的Bean * <bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver"></bean> *  需要写上id，不写则会报错，可能SpringMVC源码用到，有空再研究SpringMVC * 2、在SpringMVC中配置 LocaleChangeInterceptor 的拦截器Interceptor * org.springframework.web.servlet.i18n.LocaleChangeInterceptor * 3、url通过带参locale=zh_CN/locale=en_US * 则会读取properties中的翻译文件 *  *  */@Autowiredprivate ResourceBundleMessageSource messageSource;@RequestMapping("i18N")public String i18N(Locale locale){String result = messageSource.getMessage("i18N.age", null, locale);System.out.println(result);return "index";}}
