前提：
在resources目录下建立 messages_en_US.properties、messages_zh_CN.properties语言配置文件。
定义变量，如下： school_cover_title = School Cover
实现：
1. 启动文件中代码如下配置：
public class TwSpringCloudBigScreenWebApplication extends WebMvcConfigurerAdapter
{ public static void main(String[] args)
{
TimeZone.setDefault(TimeZone.getTimeZone("GMT+8"));
SpringApplication.run(TwSpringCloudBigScreenWebApplication.class, args);
} @Bean
public LocaleResolver localeResolver() {
SessionLocaleResolver slr = new SessionLocaleResolver();
slr.setDefaultLocale(Locale.SIMPLIFIED_CHINESE);
return slr;
} @Bean
public LocaleChangeInterceptor localeChangeInterceptor() {
LocaleChangeInterceptor lci = new LocaleChangeInterceptor();
lci.setParamName("lang");
return lci;
} @Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(localeChangeInterceptor());
}
}
2. Controller 类中定义请求响应
@RequestMapping(value={"", "/", "/index"}, method = RequestMethod.GET)
public String index(ModelMap model)
{
if(null == chinaMapUrl || chinaMapUrl.length() == 0)
{
chinaMapUrl = "http://218.77.50.45:8222/showroom/front/first/map_pass";
}
model.addAttribute("chinaMapUrl",chinaMapUrl);
return "index";
}
3. index.html静态页面中定义切换按钮
<a href="?lang=en_US" > 英语</a>
<a href="?lang=zh_CN" > 中文</a>
实现以上三步，即可实现语言切换。
