스프링 로캘 리졸버 체인 연결

Question

로캘 확인자를 연결할 수 있습니까?

내가로부터 로케일 값을 싶습니다

1. 세션을 경우 내 가능 언어

2. 쿠키의 경우를 가진지도 내 가능 언어

3. 두 경우와지도 로케일 정보를 포함하지 마십시오. 허용 ​​언어에서 추출한 후 허용 된 로케일과 가장 일치하는 항목을 선택하십시오.

어떻게 하시겠습니까?

Answer 1

스프링의 로케일 분석자 목록을 래핑하는 자신의 LocaleResolver을 작성해야한다고 생각합니다. Locale이 해결 될 때까지 하나씩 호출합니다. 목록에 Locale이 없으면 LocaleResolver에 기본 동작을 제공합니다.

/** 
* This locale resolver provides the ability to define a list of resolvers from which to determine 
* the locale. This allows us to give preference to certain locale resolution schemes by putting 
* them earlier in the list. 
* <p/> 
* 
* The order of resolvers from which to find the given locale (or set a specified locale) could be 
* defined in the spring context file with something like: 
* 
* <pre> 
* &lt;bean id=&quot;localeResolver&quot; class=&quot;org.lds.stack.web.spring.i18n.ChainedLocaleResolver&quot;&gt; 
*  &lt;property name=&quot;localeResolvers&quot;&gt; 
*   &lt;list&gt; 
*    &lt;bean class=&quot;org.lds.stack.web.spring.i18n.UrlLocaleResolver&quot; /&gt; 
*    &lt;bean class=&quot;org.lds.stack.web.spring.i18n.NoDefaultSessionLocaleResolver&quot; /&gt; 
*    &lt;bean class=&quot;org.lds.stack.web.spring.i18n.NoDefaultCookieLocaleResolver&quot;&gt; 
*     &lt;property name=&quot;cookieMaxAge&quot; value=&quot;31536000&quot;/&gt; 
*    &lt;/bean&gt; 
*    &lt;bean class=&quot;org.springframework.web.servlet.i18n.AcceptHeaderLocaleResolver&quot; /&gt; 
*    &lt;bean class=&quot;org.springframework.web.servlet.i18n.FixedLocaleResolver&quot; /&gt; 
*   &lt;/list&gt; 
*  &lt;/property&gt; 
* &lt;/bean&gt; 
* </pre> 
* 
* This allows you to remove, or re-order the locale resolution schemes to meet your needs. 
* Also note that the id of localeResolver is significant. The Spring Framework knows to use this 
* resolver as the LocaleResolver by virtue of the id being "localeResolver". 
* <p/> 
* 
* NOTE: If the default resolver order, shown above, will work for your application, then you can 
* skip this verbose definition by utilizing the stack-web namespace handler, providing any exposed 
* attribute values for minor customizations. The namespace handler is defined as follows: 
* 
* <pre> 
* &lt;stack-web:locale-resolver /&gt; 
* </pre> 
* 
* Additionally, in order to change the locale based on a url parameter, you can configure a 
* LocaleChangeInterceptor, which will call the set method of all of the locales in the chained 
* resolver, so that they can be found when resolveLocale(...) is called on them. 
* <p/> 
* 
* The interceptor configuration might look as follows: 
* <pre> 
* &lt;mvc:interceptors&gt; 
*  &lt;bean id=&quot;localeChangeInterceptor&quot; class=&quot;org.springframework.web.servlet.i18n.LocaleChangeInterceptor&quot; /&gt; 
* &lt;/mvc:interceptors&gt; 
* </pre>
