国际化

主要原理

复制代码
 public Locale resolveLocale(HttpServletRequest request) {
        Locale defaultLocale = this.getDefaultLocale();
        if (defaultLocale != null && request.getHeader("Accept-Language") == null) {
            return defaultLocale;
        } else {
            Locale requestLocale = request.getLocale();
            List<Locale> supportedLocales = this.getSupportedLocales();
            if (!supportedLocales.isEmpty() && !supportedLocales.contains(requestLocale)) {
                Locale supportedLocale = this.findSupportedLocale(request, supportedLocales);
                if (supportedLocale != null) {
                    return supportedLocale;
                } else {
                    return defaultLocale != null ? defaultLocale : requestLocale;
                }
            } else {
                return requestLocale;
            }
        }
    }
复制代码

1.首先在resources目录下新建一个i18n文件

login.properties

login.btn=登录
login.password=密码
login.remember=记住我
login.tip=请登录
login.username=用户名

login_en_US.properties

login.btn=Sign in
login.password=Password
login.remember=Remember me
login.tip=Please sign in
login.username=Username

login_zh_CN.properties

login.btn=登录
login.password=密码
login.remember=记住我
login.tip=请登录
login.username=用户名

2.找到我们配置文件的真实位置

#我们配置文件的真实位置
spring.messages.basename=i18n.login

 

3.在页面中引入属性

复制代码
<!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 th:href="@{/css/bootstrap.min.css}" rel="stylesheet">
        <!-- Custom styles for this template -->
        <link th:href="@{/css/signin.css}" rel="stylesheet">
    </head>

    <body class="text-center">
        <form class="form-signin" th:action="@{/user/login}">
            <img class="mb-4" th:src="@{/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>
            <p style="color: red" th:text="${msg}" th:if="${not #strings.isEmpty(msg)}"></p>
            <label class="sr-only" th:text="#{login.username}">Username</label>
            <input type="text"  name="username" class="form-control" th:placeholder="#{login.username}" required="" autofocus="">
            <label class="sr-only" th:text="#{login.password}">Password</label>
            <input type="password" name="password" class="form-control" 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">[[#{login.btn}]]</button>
            <p class="mt-5 mb-3 text-muted">© 2017-2018</p>
            <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>
        </form>

    </body>

</html>
复制代码

4.配置本地化解析LocaleResolver

复制代码
public class MyLocalResolver implements LocaleResolver {

    @Override
    public Locale resolveLocale(HttpServletRequest request) {
        String language = request.getParameter("l");
        System.out.println(language);
        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 httpServletRequest, HttpServletResponse httpServletResponse, Locale locale) {

    }
}
复制代码

5.将我们写的类注入到spring容器

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