我有一個非常簡單的JSF 2.0項目。動態調用消息包?
我有一個index.xhtml文件給我看拉什莫爾山的圖片。 在這個頁面上,我可以點擊圖片,我希望它去「president.xhtml」 - 沒有問題。一個簡單的動作=「」 ...
我的問題是,我的消息包文件(messages.properties)設置了靜態鍵和值,例:
jeffersonPageTitle=Thomas Jefferson
rooseveltPageTitle=Theodore Roosevelt
lincolnPageTitle=Abraham Lincoln
washingtonPageTitle=George Washington
在我的「總統.xhtml「文件,我希望它根據我點擊的內容顯示這些標題。在上面的代碼
<h:form>
<span class="presidentPageTitle">#{msgs['rushmore.president'],PageTitle}</span>
<br />
<h:graphicImage library="images" name="jefferson.jpg" styleClass="leftImage" />
<span class="presidentDiscussion">#{msgs.washingtonDiscussion}</span>
<br />
<h:commandLink action="index" styleClass="backLink">${msgs.indexLinkText}</h:commandLink>
</h:form>
下聯是我的問題 - 我不知道如何來引用GET-方法在我的Java代碼。代碼是在這裏:
@ManagedBean // or @Named
@RequestScoped
public class Rushmore {
private String outcome = null;
private Rectangle washingtonRect = new Rectangle(70, 30, 40, 40);
private Rectangle jeffersonRect = new Rectangle(115, 45, 40, 40);
private Rectangle rooseveltRect = new Rectangle(135, 65, 40, 40);
private Rectangle lincolnRect = new Rectangle(175, 62, 40, 40);
public Rushmore() {}
public void handleMouseClick(ActionEvent e) {
FacesContext context = FacesContext.getCurrentInstance();
String clientId = e.getComponent().getClientId(context);
Map<String, String> requestParams = context.getExternalContext().getRequestParameterMap();
int x = new Integer((String) requestParams.get(clientId + ".x")).intValue();
int y = new Integer((String) requestParams.get(clientId + ".y")).intValue();
outcome = null;
if (washingtonRect.contains(new Point(x, y))) {
outcome = "washington";
}
if (jeffersonRect.contains(new Point(x, y))) {
outcome = "jefferson";
}
if (rooseveltRect.contains(new Point(x, y))) {
outcome = "roosevelt";
}
if (lincolnRect.contains(new Point(x, y))) {
outcome = "lincoln";
}
System.out.println(requestParams.keySet());
}
public String getPresident() {
return outcome;
}
public String navigate() {
if(outcome != null) {
return "president";
}
else return null;
}
}
這是getPresident方法我想在president.xhtml文件到達...
任何幫助,將不勝感激:)
與您所關注的示例有什麼不同? IIRC它是Cay Horstmanns的例子之一。 – 2010-12-01 20:40:21
