prifaces扩展ajaxErrorHandler不工作

在WildFly 8-1我有primefaces-5.1.jar和primefaces-extensions-2.1.0.jar在我的webappsWEB-INF/lib目录。

我已经配置了WEB-INF/faces-config.xml:

<?xml version="1.0" encoding="UTF-8"?>
<faces-config
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd"
version="2.2">
<application>
<el-resolver>org.primefaces.application.exceptionhandler.PrimeExceptionHandlerELResolver</el-resolver>
</application>
<factory>
<exception-handler-factory>org.primefaces.application.exceptionhandler.PrimeExceptionHandlerFactory</exception-handler-factory>
</factory>
</faces-config>

我有以下JSF。

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
xmlns:h="http://xmlns.jcp.org/jsf/html"

<h:form id="form">
<pe:ajaxErrorHandler body="ERROR"/>
<p:commandButton actionListener="#{dossierResumen.excepcion}" value="Excepción"/>
</h:form>
</h:body>
</html>

其中DossierResumen#excepcion()为

public void excepcion() {
throw new NullPointerException("EXCEPCION! EXCEPCION!");
}

当我点击按钮时，我根本没有弹出窗口;页面被重定向到web.xml中定义的错误500的URL。在日志中，我得到了如下的堆栈跟踪墙:

我做错了什么?

<res-type>java.lang.String</res-type>
</resource-ref>
</web-app>

该组件有两种模式:简单模式和扩展模式。

在简单模式下，您不需要在faces-config.xml中指定任何内容。所以你可以删除这些行:

<application>
<el-resolver>org.primefaces.application.exceptionhandler.PrimeExceptionHandlerELResolver</el-resolver>
</application>
<factory>
<exception-handler-factory>org.primefaces.application.exceptionhandler.PrimeExceptionHandlerFactory</exception-handler-factory>
</factory>

或者删除整个faces-config.xml文件，因为它是你在那里唯一的东西。然后，您可以测试简单模式，它可以正常工作，而无需在web.xml中定义任何其他内容。这可能足以满足您的需求.

从错误跟踪来看，似乎在扩展模式下(使用faces-config.xml配置)，组件需要在web.xml中定义一个错误页面。您不希望重定向到错误页面，因此，如果您将以下代码添加到web.xml中，例如可以工作，但不满足您的需要:

<error-page>
<exception-type>java.lang.Throwable</exception-type>
<location>/error/500.xhtml</location>
</error-page>

无论如何，强烈建议使用p:ajaxExceptionHandler原生组件，因为看起来PrimeFaces Extensions~~的作者可能会在将来删除该组件，因为它不再需要(链接)~~已经在3.2.0版本中删除了该组件。(链接)

如何配置您的web.xml?对我来说，它是在这个配置下工作的:

web . xml例子:

<error-page>
<exception-type>javax.faces.application.ViewExpiredException</exception-type>
<location>/pages/errorpages/sessione-scaduta.xhtml</location>
</error-page>
<error-page>
<exception-type>java.lang.Throwable</exception-type>
<location>/pages/errorpages/runtime-error.xhtml</location>
</error-page>

faces-config.xml

<application>
<message-bundle>ValidationMessages</message-bundle>
<resource-bundle>
<base-name>/Bundle</base-name>
<var>bundle</var>
</resource-bundle>
<el-resolver>
org.primefaces.application.exceptionhandler.PrimeExceptionHandlerELResolver
</el-resolver>
<locale-config>
<default-locale>it</default-locale>
</locale-config>
<view-handler>it.infogroup.wrl.web.utils.PathTrimViewHandler</view-handler>
</application>
<factory>
<exception-handler-factory>
org.primefaces.application.exceptionhandler.PrimeExceptionHandlerFactory
</exception-handler-factory>
</factory>

使用此配置，您将在错误时重定向。

如果你需要弹出，你需要改变代码，像这样(从primefaces展示):

<p:ajaxExceptionHandler type="java.lang.NullPointerException"
update="exceptionDialog"
onexception="PF('exceptionDialog').show();" />
<p:dialog id="exceptionDialog" header="Exception '#{pfExceptionHandler.type}' occured!" widgetVar="exceptionDialog"
height="500px">
Message: #{pfExceptionHandler.message} <br/>
StackTrace: <h:outputText value="#{pfExceptionHandler.formattedStackTrace}" escape="false" /> <br />
<p:button onclick="document.location.href = document.location.href;"
value="Reload!"
rendered="#{pfExceptionHandler.type == 'javax.faces.application.ViewExpiredException'}" />
</p:dialog>
