我如何导航到 JSF 中的另一个页面?
How can I navigate to another page in JSF?
我正在使用 JSF/PrimeFaces 开发小型 Web 应用程序。我可以从网络调用 bean,但是,我无法 return 网络。这是我的:
requestLeave.xhtml
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:p="http://primefaces.org/ui"
xmlns:f="http://java.sun.com/jsf/core">
<h:head>
<title>Request leave</title>
</h:head>
<h:body>
<script language="javascript">
var today = new Date();
document.write(today);
</script>
<h:form id="form" >
<h:panelGrid id= "grid" columns="2" cellpadding="5">
<f:facet name="header">
<p:messages id="msgs" />
</f:facet>
<h:outputLabel for="title" value="Leave Title:" style="font-weight:bold" />
<p:inputText value="#{requestLeave.titleLeave}" required="true" requiredMessage="title is required." />
<h:outputLabel for="type" value="Type:" style="font-weight:bold" />
<p:inputText value="#{requestLeave.typeLeave}" required="true" requiredMessage="type is required." />
<p:commandButton value="Submit" actionListener="#{requestLeave.buttonAction}" />
</h:panelGrid>
</h:form>
</h:body>
</html>
RequestLeave.java
import javax.faces.bean.ManagedBean;
@ManagedBean
public class RequestLeave {
private String titleLeave;
private String typeLeave;
public String getTitleLeave() {
return titleLeave;
}
public void setTitleLeave(String titleLeave) {
this.titleLeave = titleLeave;
}
public String getTypeLeave() {
return typeLeave;
}
public void setTypeLeave(String typeLeave) {
this.typeLeave = typeLeave;
}
public String buttonAction() {
System.out.println("leave title " + titleLeave);
System.out.println("leave type " + typeLeave);
return ("index.jsp");
}
}
有了这个,我不能return到index.jsp。谁能帮我?提前致谢。
将 actionListener
属性更改为 action
:
<p:commandButton value="Submit" action="#{requestLeave.buttonAction}" />

action
and actionListener
