read-Atleap-2-动态改变页面显示语言
Atleap中struts tiles主模板页面是：/WEB-INF/pages/layouts/core/coreLayout.jsp
Ø 改变页面显示语言
<definition name=".switchLocaleForm" extends=".blockLayout"
controllerClass="com.blandware.atleap.webapp.action.core.contentLocale
.LocaleListController"> （1）
<put name="blockBody"
value="/WEB-INF/pages/core/contentLocale/switchLocaleForm.jsp" />（2）
</definition>
（1）的说明，取得locale表中的本地化信息，形成List,存入request中
Ø 进入修改语言页面之前执行的操作
public final class LocaleListController extends ControllerSupport {
/**
* Retrieves all locales and puts them into request
*/
public void execute(ComponentContext tilesContext, HttpServletRequest request, HttpServletResponse response, ServletContext servletContext)
throws Exception {
WebApplicationContext ctx = WebApplicationContextUtils.getRequiredWebApplicationContext(servletContext);
LookupManager lookupManager = (LookupManager) ctx.getBean(Constants.LOOKUP_MANAGER_BEAN);
List localesList = lookupManager.listActiveContentLocales();
request.setAttribute(WebappConstants.LANGUAGES_COLLECTION_KEY, localesList);
}
// public static final String LANGUAGES_COLLECTION_KEY = //"com.blandware.atleap.LANGUAGES_COLLECTION";
}
Ø LookupManagerImpl的listActiveContentLocales方法
public List listActiveContentLocales() {
List contentLocales = lookupDAO.listActiveContentLocales();
List result = new ArrayList();
for ( Iterator i = contentLocales.iterator(); i.hasNext(); ) {
Object[] values = (Object[]) i.next();
String label = (String) values[0];
String value = (String) values[1];
LabelValue labelValue = new LabelValue(label, value);
result.add(labelValue);
}
return result;
}
ØLookupDAOHibernate的listActiveContentLocales方法
public List listActiveContentLocales() {
return executeFind("select l.name, l.identifier from ContentLocale l where l.active = 'T' order by l.identifier", true, null);
}
+------------+---------+----------------+------------------+--------+
| identifier | version | name | default_instance | active |

Ø lookupManager bean
<!-- Lookup Manager Implementation -->
<bean id="lookupManager" class="com.blandware.atleap.service.core.impl.LookupManagerImpl">
<property name="lookupDAO">
<ref bean="lookupDAO"/>
</property>
<property name="localizableDAO">
<ref bean="localizableDAO"/>
</property>
</bean>
Ø lookupDAO bean
<bean id="lookupDAO" class="com.blandware.atleap.persistence.hibernate.core.LookupDAOHibernate">
<property name="sessionFactory">
<ref local="sessionFactory"/>
</property>
</bean>
Ø localizableDAO bean
<!-- LocalizableDAO: Hibernate implementation -->
<bean id="localizableDAO" class="com.blandware.atleap.persistence.hibernate.core.LocalizableDAOHibernate">
<property name="sessionFactory">
<ref local="sessionFactory"/>
</property>
</bean>
（2）的说明，
Ø Struts-config.xml设置
<action
path="/switchLocale"
type="com.blandware.atleap.webapp.action.core.contentLocale.SwitchLocaleAction"
name="switchLocaleForm"
scope="request"
unknown="false"
validate="false"
>
Ø switchLocaleForm.jsp中调用的struts action
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse
response) throws Exception {
SwitchLocaleForm switchLocaleForm = (SwitchLocaleForm) form;
Locale newLocale = new Locale(switchLocaleForm.getLocaleIdentifier());
String redirectUrl = switchLocaleForm.getRedirectUrl();
request.getSession().setAttribute(Globals.LOCALE_KEY, newLocale);
ActionForward redirect = new ActionForward();
redirect.setRedirect(true);
redirect.setPath(redirectUrl);
return redirect;
}
