我有一个faces-config.xml,其中包含很多导航规则,但我无法在我的页面中获得重定向参数。
我对这个问题进行了很多搜索,但是找不到任何帮助。
detail.xhtml:
<p:commandLink action="#{bean.delete()}">
<f:setPropertyActionListener target="#{bean.deletionSuccess}" value="true" />
<p:confirm header="Confirmation" message="Are you sure?"
</p:commandLink>
faces-config.xml中:
<navigation-rule>
<from-view-id>/myDetailPage.xhtml</from-view-id>
<navigation-case>
<from-outcome>deletionSuccess</from-outcome>
<to-view-id>/myOverviewPage.xhtml</to-view-id>
<redirect/>
</navigation-case>
</navigation-rule>
Java的豆:
private String deletionSuccess;
public String delete() {
// do something
return "deletionSuccess";
}
public void setDeletionSuccess(String deletionSuccess) { this.deletionSuccess = deletionSuccess; }
public String getDeletionSuccess() { return deletionSuccess; }
overview.xhtml:
<f:metadata>
<f:viewParam name="deletionSuccess" value="#{bean.deletionSuccess}"/>
<f:viewAction action="#{bean.init}"/>
</f:metadata>
...
<h:form id="mainform" class="form-horizontal overview" role="form" method="post">
<h:panelGroup styleClass="row" rendered="#{!empty housePlantBean.deletionSuccess}">
...
我做错了什么?或者如何在我的XHTML页面中获取redirect-param?
非常感谢你的帮助!

这不会以这种方式运作。
首先,您需要在<f:viewParam>
facelet上定义myOverviewPage.xhtml
,例如:
<f:metadata>
<f:viewParam name="deletionSuccess" value="#{bean.deletionSuccess}"/>
</f:metadata>
我想你已定义了它。
传递参数的简便方法是在<h:button>
facelet上使用<h:link>
或myDetailPage.xhtml
,例如:
<h:button outcome="deletionSuccess">
<f:param name="deletionSuccess" value="#{true}"/>
</h:button>
但没有调用public String delete()
方法。
因此,如果您想要重定向和调用此方法,则应使用<h:commandButton>
或<h:commandLink>
,例如:
<h:commandButton value="submit" action="#{bean.delete}">
<f:setPropertyActionListener target="#{bean.deletionSuccess}" value="#{true}" />
</h:commandButton>
---更新
请在navigation-rule
<navigation-rule>
<from-view-id>/detail.xhtml</from-view-id>
<navigation-case>
<from-outcome>deletionSuccess</from-outcome>
<to-view-id>/overview.xhtml</to-view-id>
<redirect include-view-params="true"/>
</navigation-case>
</navigation-rule>
请添加到detail.xhtml
:
<p:confirmDialog global="true" showEffect="fade" >
<p:commandButton value="Yes" type="button" styleClass="ui-confirmdialog-yes" icon="ui-icon-check"/>
<p:commandButton value="No" type="button" styleClass="ui-confirmdialog-no" icon="ui-icon-close"/>
</p:confirmDialog>
或删除
<p:confirm header="Confirmation" message="Are you sure?"/>
来自<p:commandLink>
