JSF2动作参数 [英] JSF2 Action parameter

问题描述

我已经阅读了有关通过actionListener将参数从jsf页面传递到managedbean的信息.是否还可以将参数传递给简单的操作方法?

I have read about passing parameters from jsf page to managedbean through actionListener. Is it also possible to pass a parameter to a simple action method?

感谢您阅读...

谢谢你们的建议！没有你，我会迷路的:-)

Thank you both for your advices! I would be lost without you :-)

以下为我工作:

<h:commandLink id="link" action="#{overviewController.showDetails}" >
   <f:setPropertyActionListener target="#{overviewController.show_id}" value="#{project.id}" />
   <h:outputText value="#{project.title}" />
</h:commandLink>

那么，现在谁该当绿色勾号呢? :-P我可以给他们两个吗?

So now who deserves the green tick? :-P can I give two of them?

推荐答案

是.要么

action="#{bean.method(param)}"

或

<h:commandButton .. >
    <f:setPropertyActionListener
         target="#{bean.targetProperty}" value="#{param}" />
</h:commandbutton>

(并在方法中使用bean属性)

(and use the bean property in the method)
