SpringBoot国际化

目前正在学习Spring Boot框架  学习到国际化

刚开始配置好了国际化相关文件(messages.properties,messages_en_US.properties,messages_zh_CN.properties,messages_ja_JP.properties)

写了一个 MyLocaleResolver implements LocaleResolver 类

@Override
public Locale resolveLocale(HttpServletRequest httpServletRequest) {
    String localeStr = httpServletRequest.getParameter("l");
    Locale locale = Locale.getDefault();//获取默认语言环境
    if (!StringUtils.isEmpty(localeStr)) {
        String[] split = localeStr.split("_");
        locale = new Locale(split[0], split[1]);
    }
    return locale;
}

然后写了 WebMvcConfig implements WebMvcConfigurer 类

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

前台页面

<#import "spring.ftl" as spring/>
.....

<form id="submitForm" action="" method="post">
   <div id="login_tip">
      <span id="login_err" class="sty_txt2"></span>
   </div>
   <div>
      <@spring.message code="username"/>
       <input type="text" name="username" class="username" id="name">
   </div>
   <div>
      <@spring.message code="password"/>
      <input type="password" name="password" class="pwd" id="pwd" onkeypress="EnterPress(event)" onkeydown="EnterPress()">
   </div>
   <div id="btn_area">
      <input type="button" class="login_btn" id="login_sub" value="<@spring.message code='login'/>">
      <input type="reset" class="login_btn" id="login_ret" value="<@spring.message code='reset'/>">
   </div>
   <a href="/test/tologin?l=zh_CN">中文</a>
   <a href="/test/tologin?l=en_US">英文</a>
   <a href="/test/tologin?l=ja_JP">日文</a>
</form>

之后在网页上运行 只能设置浏览器语言才能更换中英文,点击a标签始终不管用,在网上找了很久才解决
参考了一篇博客,忘记地址了,说是 在@Bean后加(name="localeResolver")

@Bean(name="localeResolver")
public LocaleResolver LocaleResolver(){
    return new MyLocaleResolver();
}
重新运行,果然点击a标签也能切换了
