Spring boot 国际化 eng 没有效果

标签 spring spring-boot spring-mvc

我想将 th:text = "#{title.text}" 更改为 eng lang 但它显示泰语 lang 我尝试根据 this exmple 更改代码 但它不起作用。

输出放入页面登录？lang=en enter image description here 登录 Controller

最佳答案

您缺少的是 messages.properties 中的两个或(所有其他语言)文件中的相同文本 和 messages_th.properties

假设标题是你好

messages.properties

title.text = hello

messages_th.properties

title.text = \u0E2A\u0E27\u0E31\u0E2A\u0E14\u0E35

泰语中酒店管理系统的等效项是 ระบบการจัดการโรงแรม

Unicode: \u0E23\u0E30\u0E1A\u0E1A\u0E01\u0E32\u0E23\u0E08\u0E31\u0E14\u0E01\u0E32\u0E23\u0E42\u0E23\u0E07\u0E41\u0E23\u0E21

当您将泰语中的 hello 粘贴到 IDE 中时，Google 翻译会将泰语中的 hello 翻译为 สวัสดี，它可能会自动转换为 Unicode(对于 Windows 上的 Eclipse)

Translate

更新:

可能您错过了我在 HTML 或类似操作中根据语言更改内容的操作 window.location.replace('international?lang=' + selectedOption);

messages.properties

title.text = Hello
lang.change=Change the language
lang.eng=English
lang.th=Thai

messages_th.properties

title.text= \u0E2A\u0E27\u0E31\u0E2A\u0E14\u0E35
lang.change=\u0E40\u0E1B\u0E25\u0E35\u0E48\u0E22\u0E19\u0E20\u0E32\u0E29\u0E32
lang.eng=\u0E2D\u0E31\u0E07\u0E01\u0E24\u0E29
lang.th=\u0E44\u0E17\u0E22

Controller 

 @RequestMapping(value = "/international" , method = RequestMethod.GET)
        public ModelAndView login() {
            ModelAndView modelAndView = new ModelAndView();
            modelAndView.setViewName("login");
            return modelAndView;
 }

HTML 

.....

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js">
</script>
<script type="text/javascript">
$(document).ready(function() {
    $("#locales").change(function () {
        var selectedOption = $('#locales').val();
        if (selectedOption != ''){
            window.location.replace('international?lang=' + selectedOption);
        }
    });
});
</script>

<body class="bg-gradient-primary">

<span th:text="#{lang.change}"></span>:
<select id="locales">
    <option value=""></option>
    <option value="en" th:text="#{lang.eng}"></option>
    <option value="th" th:text="#{lang.th}"></option>
</select>

</body>
</html>

WebMvcConfig

@Override
    public void addViewControllers(ViewControllerRegistry registry) {
       registry.addViewController("/international").setViewName("login.html");
    }
