1、创建配置文件文件名+_en_US.properties

login_en_US.properties

login_zh_CN.properties

设置值

2、配置配置文件路径

#国际化文件路径 login 去掉语言的文件
spring.messages.basename=i18n.login

3、编写登陆页面

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
   <head>
      <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
      <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
      <meta name="description" content="">
      <meta name="author" content="">
      <title>Signin Template for Bootstrap</title>
      <!-- Bootstrap core CSS -->
      <link href="asserts/css/bootstrap.min.css" th:href="@{/webjars/bootstrap/4.0.0/css/bootstrap.css}" rel="stylesheet">
      <!-- Custom styles for this template -->
      <link href="asserts/css/signin.css"  th:href="@{asserts/css/signin.css}" rel="stylesheet">
   </head>

   <body class="text-center">
      <form class="form-signin" action="dashboard.html">
         <img class="mb-4" th:src="@{/asserts/img/bootstrap-solid.svg}" src="asserts/img/bootstrap-solid.svg" alt="" width="72" height="72">
         <h1 class="h3 mb-3 font-weight-normal" th:text="#{login.tip}">Please sign in</h1>
         <label class="sr-only" th:text="#{login.Username}" >Username</label>
         <input type="text" class="form-control" placeholder="Username" th:placeholder="#{login.Username}" required="" autofocus="">
         <label class="sr-only" th:text="#{logon.Password}" >Password</label>
         <input type="password" class="form-control" placeholder="Password"  th:placeholder="#{logon.Password}" required="">
         <div class="checkbox mb-3">
            <label>
          <input type="checkbox" value="remember-me"  />  [[#{login.remember}]]
        </label>
         </div>
         <button class="btn btn-lg btn-primary btn-block" type="submit"  th:text="#{login.btn}">Sign in</button>
         <p class="mt-5 mb-3 text-muted">© 2017-2018</p>
         <a class="btn btn-sm" th:href="@{/login.html(l='zh_CN')}">中文</a>
         <a class="btn btn-sm" th:href="@{/login.html(l='en_US')}">English</a>
      </form>

   </body>

</html>

主要地方

<label class="sr-only" th:text="#{logon.Password}" >Password</label>

<input type="password" class="form-control" placeholder="Password" th:placeholder="#{logon.Password}" required="">

配置文件便编码：

ok ,点击查询即可以根据浏览器查询对应语言。

4、点击链接切换国际化

<a class="btn btn-sm" th:href="@{/login.html(l='zh_CN')}">中文</a>
<a class="btn btn-sm" th:href="@{/login.html(l='en_US')}">English</a>

自定义LocaleResolver

package com.example.springbootweb.component;

import org.springframework.util.StringUtils;
import org.springframework.web.servlet.LocaleResolver;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Locale;

public class MyLocaleResolver implements LocaleResolver {
    //解析区域信息
    @Override
    public Locale resolveLocale(HttpServletRequest httpServletRequest) {
        String l = httpServletRequest.getParameter("l");
        Locale local = Locale.getDefault();
        if(StringUtils.hasLength(l)){
            String[] split = l.split("_");
            local = new Locale(split[0],split[1]);
        }
        return local;
    }
    @Override
    public void setLocale(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Locale locale) {

    }
}

加入容器：

@Bean
public LocaleResolver localeResolver(){
    return new MyLocaleResolver();
}

5、开发期间模板引擎页面修改以后，要实时生效

1）、禁用模板引擎的缓存

# 禁用缓存
spring.thymeleaf.cache=false

2）、页面修改完成以后ctrl+f9：重新编译；
