Question

So another application directs user to my server. The redirect is Post request (application/json) with value language in the JSON. How should I set the locale value in RestController? So that Thymeleaf could render the correct text.

Setting locale with LocaleContextHolder doesn't do the trick.

Answer 1

您应该遵循本指南here，因为国际化是spring-boot中的常见任务。如果您需要一个简短的答案：

首先在您的 Application.java 中配置一个debug：

celery

然后再次在您的 Application.java 文件中配置LocaleChangeInterceptor：

LocaleResolver

最后注册您的 LocaleChangeInterceptor （也在Application.java中）：

@Bean(name = "localeResolver")
public LocaleResolver localeResolver() {
  SessionLocaleResolver slr = new SessionLocaleResolver();
  slr.setDefaultLocale(new Locale("tr", "TR"));
  return slr;
}

现在，如果您随POST请求一起发送名为“ lang” 的 请求参数 ，则spring将使用其值来确定所需的语言环境，并相应地进行更改。

最终得到以下解决方案：

WebMvcConfigurer有这些

    @Bean
    public LocaleResolver localeResolver() {
        SessionLocaleResolver r = new SessionLocaleResolver();
        r.setDefaultLocale(new Locale("jp"));
        return r;
    }

在控制器中，我将此类称为公共方法：


@Component
public class WebLanguage {
    public void setLocale(HttpServletRequest request, HttpServletResponse response) {
        if (!request.getParameterMap().containsKey("lang")) return;

        LocaleResolver localeResolver = localeResolver(request);
        localeResolver.setLocale(request, response, new Locale(request.getParameterMap().get("lang")[0]));
    }

    LocaleResolver localeResolver(HttpServletRequest request) {
        return RequestContextUtils.getLocaleResolver(request);
    }

}

Springboot locale with Rest request and Thymeleaf
