切换语言环境（日语），但它返回英语（默认）。如何检索 jp_JP 语言环境？
回答by Mohammad tanvirul islam
//Return the Locale associated with the current thread,
// if any, or the system default Locale else(English)
LocaleContextHolder.getLocale();
so first you check is your current thread.for set you locale in current thread use :
所以首先你检查是你当前的线程。在当前线程使用中设置你的语言环境：
setLocale(Locale locale);
method and then LocaleContextHolder.getLocale() will return jp_JP locale
方法然后 LocaleContextHolder.getLocale() 将返回 jp_JP 语言环境

RequestContextUtils
请求上下文实用程序
This should allow you to get the current locale of your request:
这应该允许您获取请求的当前语言环境：
RequestContextUtils.getLocaleResolver(request).resolveLocale(request);
Return the LocaleResolverthat has been bound to the request by the DispatcherServlet.
@param requestcurrent HTTP request
@return the current LocaleResolver, or {@code null}if not found:
返回LocaleResolver已绑定到请求的DispatcherServlet。
@paramrequest当前 HTTP 请求
@return 当前的LocaleResolver，或者{@code null}如果没有找到：
public static LocaleResolver getLocaleResolver(HttpServletRequest request) {
return (LocaleResolver) request.getAttribute(DispatcherServlet.LOCALE_RESOLVER_ATTRIBUTE);
}
This will return a LocaleResolver from where you than can load the locale.
这将返回一个 LocaleResolver，您可以从中加载语言环境。
LocaleContextHolder
LocaleContextHolder
Or as metioned by: Mohammad tanvirul islam:
或者正如所提到的：Mohammad tanvirul islam：
LocaleContextHolder.getLocale();
