我设法用Primefaces运行WAB包。问题是某些示例正在运行，并且当我尝试实现它们时，一些示例存在问题。我测试了这个例子：

可能导致此问题的原因是什么？
更新
我改变了托管bean的名称。事实证明，框架正在搜索托管bean的错误名称 - avax.el.MethodNotFoundException: Method not found: com.DX_57.HM_57.Linux@c280dca.save()。它应该是avax.el.MethodNotFoundException: Method not found: com.DX_57.HM_57.Linux@LinuxController.save()这是配置问题吗？
答案 0 :(得分：6)
这是因为CDI本身不支持ViewScoped。要么将@Named("LinuxController")更改为@ManagedBean(name="LinuxController")以使其成为纯JSF，要么将ViewScoped更改为Seam的ConversationalScope或SessionScope之类的其他内容（或者我认为RequestScope就好了）
P.S。还要看看你是否为ActionEvent实现了正确的包，它曾经花了我两个小时才发现我有java.awt.event.ActionEvent而不是来自JSF的正确的： - ）
修改
那你究竟尝试了什么？你是否改变了bean的范围，使其成为ManagedBean而不是CDI bean，在页面和bean中改变了方法名称？或者你可以创建另一个具有相同签名的bean并尝试重现错误。还尝试为text变量赋值，以查看方法getText是否正常工作。在你试图缩小可能的选择范围之前，很难说问题出在哪里。
<强>解
好的，所以我希望我找到了适合你的解决方案。您应该决定是否要使用CDI或纯JSF。如果您想使用CDI方式，请将bean注释为@Named，然后使用其他范围ViewScoped。如果您选择JSF方式，则将@Named更改为@ManagedBean，然后您可以保留ViewScoped。在这两种情况下，您都应该删除faces-config.xml中的托管bean记录，它是在注释JSF 1.2之前与@ManagedBean一起使用的，所以它现在已被弃用（并且您不能同时使用这两个注释）并在配置中记录，你必须选择其中一个选项）。
您还需要改善进口。正如我之前写的那样，您已导入java.awt.ActionEvent，但需要javax.faces.event.ActionEvent。另请注意，如果您使用CDI，则从javax.enterprise.context.*包中导入范围（RequestScoped，SessionScoped，...）的所有注释（请参阅ViewScope缺失）以及是否要将JSF与ManagedBean一起使用从javax.faces.bean.*导入所有内容。你不能将它们混合在一起，因为那样你会得到一些奇怪的错误，比如你的错误。
Here是已更改的文件。
您还应该遵循Java对话并使用CamelCase来命名您的方法（即不是 gettext（），而是 getText（））。这对于JSF表达式语言尤其重要，因为你需要setter和getter来访问页面上的bean属性，这些方法应该用CamelCase编写，所以JSF EL可以解析它们。
