p：按钮结果抛出NPE而h：outputLink值有效

时间：2013-07-06 12:55:19

标签： jsf jsf-2 primefaces prettyfaces

此代码有效：

<h:outputLink value="/admin/product/read">
    Navigate
    <f:param name="product" value="#{...}" />
</h:outputLink>

但这不是：

<p:button outcome="/admin/product/read" value="Navigate">
    <f:param name="product" value="#{...}" />
</p:button>

我正在使用Prettyfaces所以我猜Primefaces无法在read中找到'file'/admin/product，因此抛出NullPointerException（在使用{渲染页面时） {1}}）因为它无法匹配任何导航包。

我正在尝试实现p:button来生成包含参数的GET请求。由于其他元素的匹配样式，我正在替换p:button。

使用h:outputLink（或任何其他对象）渲染将产生GET请求的Primefaces样式按钮的正确方法是什么？

修改

根据要求，堆栈跟踪：

p:button

我已经在网上阅读了多个主题，其中指出由于缺少任何匹配的导航包而发生这种情况，他们还没有（还）努力抛出更好的例外。

匹配Prettyfaces案例

还有许多其他案例，但在这种情况下，它们都不相关。 <url-mapping id="adminProduct"> <pattern value="/admin/product/read" /> <view-id value="/management/product/read.xhtml" /> </url-mapping> <url-mapping id="adminEditProduct"> <pattern value="/admin/product/edit" /> <view-id value="/management/product/edit.xhtml" /> </url-mapping> <rewrite trailingSlash="remove" /> 是发生错误的页面。 edit.xhtml是使用给定GET请求定位的页面。

此问题是由于您使用最终URL作为导航“结果”这一事实造成的，该导航“结果”必须实际映射到指定的导航案例或隐式导航案例（匹配磁盘上的视图文件）。

要解决此问题，您应该按照预期使用“outcome”属性（我同意JSF文档可能更清楚），并在您的按钮配置中使用view-id：

<p:button outcome="/management/product/read.xhtml" value="Navigate">
    <f:param name="product" value="#{...}" />
</p:button>

这将导致NavigationCase成功解析，并且当使用HttpServletResponse.encodeUrl()对URL进行编码时，PrettyFaces将处理将URL重写为所需的“/admin/product/edit”。

请注意，您还可以使用PrettyFaces导航系统实现此目的（并将视图文件与其在磁盘上的位置分离）：

<p:button outcome="pretty:adminEditProduct" value="Navigate">
    <f:param name="product" value="#{...}" />
</p:button>

这将获得相同的结果，但这意味着您只有一个地方（PrettyFaces配置）来跟踪哪个视图文件与哪个URL匹配。

由于我们在“结果”标记中提供的文件缺失，因此会从当前文件的上下文路径中删除此异常。

例如： 第一页的上下文路径是 Admin / Home / page1.xhtml ，第二页是 Admin / Page2.xhtml

如果我们从page2调用page1，如outcome="page1.xhtml，那么它将抛出该异常，而我们需要从当前上下文路径中提供路径，如outcome="../page1.xhtml"。
