1、根据浏览器语言设置的信息切换了国际化
1）编写国际化配置文件，抽取页面需要显示的国际化消息
编写国际化配置文件
抽取页面需要显示的国际化消息，并配置
2）使用ResourceBundleMessageSource管理国际化资源文件
- 在application.properties配置文件中，添加国际化配置文件路径，使其生效
# 页面国际化配置,路径如步骤1的图片所示
spring.messages.basename=i18n.login
- SpringBoot自动配置好了管理国际化资源文件的组件;
ConfigurationProperties(prefix="spring.messages") publicclassMessageSourceAutoConfiguration{
/**
* Comma‐separated list of basenames (essentially a fully‐qualified classpath
* location), each following the ResourceBundle convention with relaxed support for
* slash based locations. If it doesn't contain a package qualifier (such as
* "org.mypackage"), it will be resolved from the classpath root.
*/
private String basename = "messages"; //我们的配置文件可以直接放在类路径下叫messages.properties;
@Bean
public MessageSource messageSource() {
ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
if (StringUtils.hasText(this.basename)) {
//设置国际化资源文件的基础名(去掉语言国家代码的) messageSource.setBasenames(StringUtils.commaDelimitedListToStringArray(
StringUtils.trimAllWhitespace(this.basename)));
}
if (this.encoding != null) {
messageSource.setDefaultEncoding(this.encoding.name());
}
messageSource.setFallbackToSystemLocale(this.fallbackToSystemLocale);
messageSource.setCacheSeconds(this.cacheSeconds);
messageSource.setAlwaysUseMessageFormat(this.alwaysUseMessageFormat);
return messageSource;
}
3）在页面使用fmt:message取出国际化内容
<!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 href="asserts/css/bootstrap.min.css"-->
<link th:href="@{/webjars/bootstrap/4.3.1/css/bootstrap.css}" rel="stylesheet">
<!-- Custom styles for this template href="asserts/css/signin.css"-->
<link th:href="@{/asserts/css/signin.css}" rel="stylesheet">

<body class="text-center">
<form class="form-signin" action="dashboard.html">
<!--src="asserts/img/bootstrap-solid.svg"-->
<img class="mb-4" th:src="@{/asserts/img/bootstrap-solid.svg}" alt="" width="72" height="72">
<h1 class="h3 mb-3 font-weight-normal" th:text="#{login.top}">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="#{login.password}">Password</label>
<input type="password" class="form-control" placeholder="Password" th:placeholder="#{login.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">中文</a>
<a class="btn btn-sm">English</a>
</form>
</body>
</html>
2、点击链接切换国际化
1）编写国际化配置文件，抽取页面需要显示的国际化消息
同上
2）给中英文选择加链接
<a class="btn btn-sm" th:href="@{/index.html(l='zh_CN')}">中文</a>
<a class="btn btn-sm"th:href="@{/index.html(l=en_US)}">English</a>
th:href="@{/index.html(l='zh_CN')}说明：
/index.html：访问页面的路径
l='zh_CN'：国际化的参数，带不带引号都可以
3）配置国际化代码
package com.mystudy.springboot.config;
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;
/**
* 可以在连接上携带区域信息
*/
public class MyLocaleResolver implements LocaleResolver {
@Override
public Locale resolveLocale(HttpServletRequest httpServletRequest) {
String parameter = httpServletRequest.getParameter("l");
//如果为空，返回默认信息
Locale locale = Locale.getDefault();
if(!StringUtils.isEmpty(parameter)){
String[] split = parameter.split("_");
locale = new Locale(split[0],split[1]);
}
return locale;
}
@Override
public void setLocale(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Locale locale) {
}
}
将写好的配置代码加入容器中
package com.mystudy.springboot.config;
import com.mystudy.springboot.interceptor.LoginInterceptor;
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.*;
@Configuration
public class MyMvcConfig implements WebMvcConfigurer {
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/").setViewName("login");
registry.addViewController("/index.html").setViewName("login");
}
// @Override
// public void addInterceptors(InterceptorRegistry registry) {
// // 注册拦截器
// InterceptorRegistration addInterceptor = registry.addInterceptor(new LoginInterceptor());
// // 配置拦截器路径
// addInterceptor.addPathPatterns("/**");
// // 配置不拦截路径
// addInterceptor.excludePathPatterns("/login","/","/index.html");
//
// }
// 将国际化配置加入到容器中，当有手动加入的配置时，SpringBoot默认的国际化配置将不再生效
@Bean
public LocaleResolver localeResolver(){
return new MyLocaleResolver();
}
}
