你用Spring标记了你的问题,所以我建议你使用Spring MessageSource。 Spring MessageSource可以分层聚合许多属性文件。它比旧的java ResourceBundle
提供了许多优点。
你可以在你spring-config.xml
定义春天MessageSource
这样的:
<!--
Application messages configuration.
-->
<bean id="messageSource" name="resourceBundle"
class="org.springframework.context.support.ReloadableResourceBundleMessageSource"
p:fallbackToSystemLocale="false"
p:cacheSeconds="0">
<property name="basenames">
<list>
<value>/messages/Messages</value>
<!-- <value>${application.messages}</value>-->
</list>
</property>
</bean>
比你可以定义你Class
延伸ResourceBundle
像这样(需要一些清理和重构):
public class SpringResourceBundle extends ResourceBundle
{
private MessageSource messages;
private FacesContext fc;
private Locale locale = null;
public SpringResourceBundle()
{
fc = FacesContext.getCurrentInstance();
WebApplicationContext webAppCtx = (WebApplicationContext) fc.getExternalContext().getApplicationMap().get(
WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE);
messages = (MessageSource) webAppCtx.getBean("messageSource");
}
@Override
public Locale getLocale()
{
Locale loc = fc.getELContext().getLocale();
if (fc.getExternalContext() != null) {
loc = fc.getExternalContext().getRequestLocale();
}
try {
UIViewRoot viewRoot = fc.getViewRoot();
if (viewRoot != null) {
loc = viewRoot.getLocale();
}
if (loc == null) {
loc = fc.getApplication().getDefaultLocale();
}
} catch (Throwable th) {
System.out.println(th.getMessage());
loc = locale;
}
locale = loc;
return loc;
}
@Override
protected Object handleGetObject(String key)
{
try {
return messages.getMessage(key, null, getLocale());
} catch (NoSuchMessageException e) {
return "???" + key + "???";
}
}
@Override
public Enumeration<String> getKeys()
{
return Collections.enumeration(Collections.EMPTY_LIST);
}
}
Finnaly在faces-config.xml
用上面的Class声明你的资源包。这样的事情:
<application>
<locale-config>
<default-locale>en</default-locale>
<supported-locale>cs</supported-locale>
<supported-locale>de</supported-locale>
<supported-locale>en</supported-locale>
</locale-config>
<message-bundle>your.package.SpringResourceBundle</message-bundle>
</application>
在这里你去JSF的Spring MessageSource。希望这是可以理解的。
我在想如果Spring Framework有这个解决方案吗? – Abdul
