我有一个非常简单的 JSF 2.0 项目。
我有一个 index.xhtml 文件给我看一张拉什莫尔山的照片。在这个页面上,我可以点击图片并希望它转到“president.xhtml”——这没问题。一个简单的动作=""...
我的问题是我的消息包文件(messages.properties)设置了静态键和值,例如:
jeffersonPageTitle=Thomas Jefferson
rooseveltPageTitle=Theodore Roosevelt
lincolnPageTitle=Abraham Lincoln
washingtonPageTitle=George Washington
在我的“president.xhtml”文件中,我希望它根据我点击的内容显示这些标题。
<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>
上面代码中的第二行是我的问题 - 我不知道如何在我的 java 代码中引用 get-Method。代码在这里:
@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;
}
}
这是我试图在总统.xhtml 文件中达到的 getPresident 方法......
任何帮助将非常感激 :)
