1.先在application.properties里声明国际化文件夹位置
spring.thymeleaf.cache=false spring.messages.basename=i18n.login
2.定义文件类
package com.example.mvc01.config;
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;

*/
public class MylocalResolver implements LocaleResolver {
@Override
public Locale resolveLocale(HttpServletRequest request) {
String language = request.getParameter("l");
Locale locale = Locale.getDefault();
if(!StringUtils.isEmpty(language)){
String[] split = language.split("_");
locale = new Locale(split[0],split[1]);
}
return locale;
}
@Override
public void setLocale(HttpServletRequest request, HttpServletResponse response, Locale locale) {
}
}
3.注入bean中
@Configuration
public class MyMvcConfig implements WebMvcConfigurer {
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/").setViewName("index");
registry.addViewController("/index.html").setViewName("index");
}
@Bean
public LocaleResolver localeResolver(){
return new MylocalResolver();
}
}
4.resources/i18n/目录下定义好文件如下和文件内容
login.properties --内容如lgin.tip=登陆
login_en_US.properties
login_zh_CN.properties
5.修改html文件里的模板
//语言切换链接
<h1 class="h4 text-gray-900 mb-4">
<a th:href="@{/index.html(l='zh_CN')}">中文 </a>
<a th:href="@{/index.html(l='en_US')}"> English</a>
</h1>
//文字显示内容用#号
<a href="index.html" class="btn btn-primary btn-user btn-block" :th th:text="#{login.login}">
最好点击不同的语言，上面的登陆按钮就会根据properties里的内容显示
