1.首页配置

1.所有的静态页面都要使用thymeleaf接管；

<html lang="en" xmlns:th="http://www.thymeleaf.org">

2.url: @{}

<link th:href="@{/css/bootstrap.min.css}" rel="stylesheet">

2.页面国际化

  1. 我们需要配置i18n文件

  1. 我们如果需要在项目中进行按钮切换，需要自定义一个组件LocaleResolver
package com.mine.hello.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;

//国际化语言
public class MyLocalResolver implements LocaleResolver {

//    解析请求
    @Override
    public Locale resolveLocale(HttpServletRequest request) {
//        获取请求中的语言参数
        String language = request.getParameter("l");
        Locale locale = Locale.getDefault();    //如果没有就使用默认的

//        如果请求的连接携带了国际化参数
        if(!StringUtils.isEmpty(language)){
            //zh_CN
            String[] split = language.split("_");
            //国家地区
            locale = new Locale(split[0],split[1]);
        }
        return locale;
    }

    @Override
    public void setLocale(HttpServletRequest request, HttpServletResponse response, Locale locale) {

    }
}
  1. 记得将自己写的组件配置到spring容器中 @Bean
package com.mine.hello.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.LocaleResolver;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

//如果我们要扩展springmvc，官方建议这样做
//全面接管springmvc
@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();
    }

}
