java.lang.NoSuchMethodError: org.primefaces.model.menu.MenuItem.getClientId()Ljava/lang/String

Question

我在尝试将 p:menuitem 添加到菜单时遇到问题。下面的代码是一个菜单栏的文件，会被其他网页收录。

<ui:composition 
xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ps="http://primefaces.org/spark"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:p="http://primefaces.org/ui">

<h:outputStylesheet name="css/spark-layout-blue.css" library="spark-layout" />

<h:form>  
    <ps:menu id="layout-menu">
        <p:submenu label="Opções" >  
            <p:menuitem />
        </p:submenu>  
    </ps:menu>
</h:form>

不管我在 p:menuitem 中放什么，当我尝试 运行 时，我得到这个：

HTTP Status 500 - org.primefaces.model.menu.MenuItem.getClientId()Ljava/lang/String;

type Exception report

如果我摘下 p:menuitem，它 运行 就正常了。

有什么帮助吗？

Answer 1

java.lang.NoSuchMethodError: org.primefaces.model.menu.MenuItem.getClientId()Ljava/lang/String;

该方法是运行时类路径中的 added in PrimeFaces 5.0. This problem thus implies that you're having an older PrimeFaces 版本，与 Spark 不兼容。升级吧。
