2、将上一讲ThymeleafDemo项目的内容拷贝到新项目里
打开项目的application.properties全局配置文件,在该文件中添加国际化文件基础名设置
1、使用@Configuration注解成一个配置类
2、重写resolveLocale方法,根据请求参数的值来实例化Locale对象
3、使用@Bean把这个配置类交给Spring容器进行管理
package net.yc.lesson10.resolver;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.LocaleResolver;
import org.thymeleaf.util.StringUtils;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Locale;
@Configuration
public class MyLocaleResolver implements LocaleResolver {
@Override
public Locale resolveLocale(HttpServletRequest httpServletRequest) {
//获取区域标识
String flag= httpServletRequest.getParameter("flag");
//获取区域对象
Locale locale = Locale.getDefault();
//判断区域标识是否为空
if(StringUtils.isEmpty(flag)){
//对区域标识进行处理
String[] split = flag.split("_");//使用下划线切分出一个数组,如zh_CN,["zh","CN"]
locale = new Locale(split[0], split[1]);
}
return locale;
}
@Override
public void setLocale(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Locale locale) {
}
@Bean
public LocaleResolver localeResolver() {
return new MyLocaleResolver();
}
}
用户登录页面login.html结合Thymeleaf模板引擎实现国际化功能
