- 方法详细资料
  - resolveLocaleContext
```
LocaleContext resolveLocaleContext(ServerWebExchange exchange)
```
    Resolve the current locale context via the given exchange.
    The returned context may be a TimeZoneAwareLocaleContext, containing a locale with associated time zone information. Simply apply an instanceof check and downcast accordingly.
    Custom resolver implementations may also return extra settings in the returned context, which again can be accessed through downcasting.
    参数:
    exchange - current server exchange
    返回:
    the current locale context (never null)
  - setLocaleContext
```
void setLocaleContext(ServerWebExchange exchange,
                      @Nullable
                      LocaleContext localeContext)
```
    Set the current locale context to the given one, potentially including a locale with associated time zone information.
    参数:
    exchange - current server exchange
    localeContext - the new locale context, or null to clear the locale
    抛出:
    UnsupportedOperationException - if the LocaleResolver implementation does not support dynamic changing of the locale or time zone
