我可以使用 PrimeFaces 6.0 Showcase 重现异常，因此看起来原因不在我的代码中。

这是如何使用 PrimeFaces 展示重现：

  1. 从 github下载PrimeFaces 6.0 展示源。

  2. 将 OnmiFaces 依赖项添加到pom.xml：

    <dependency>
    <groupId>org.omnifaces</groupId>
    <artifactId>omnifaces</artifactId>
    <version>2.3</version>
</dependency>

  3. 将用于创建 Payara Micro Uber Jar 的 Maven 代码从http://blog.payara.fish/creating-uber-jar-with-payara-micro添加到pom.xml

  4. 构建，mvn package然后开始java -jar showcase-6.0.jar

  5. 现在在 localhost 上启动展示并打开 DataTable Lazy Loading 示例，您应该会得到异常。

移除 OmniFaces 依赖项后，不会发生异常。它不会发生在 Payara Application Server 上，而仅发生在 Payara Micro 上。

所以我不确定错误是否出现在 OmniFaces、Payara Micro、PrimeFaces 或其他任何地方。

此行为是由添加到 OmniFaces 2.1 以支持在集群上运行的<distributable>标志引起的。

这反过来又发现了 PrimeFaces 6.0、PrimeFaces 展示应用程序和 Payara Micro 中的一些错误。

  • PrimeFaces 6.0 新PhaseInfo类 implements Serializable，但有一个PhaseId根本没有的属性Serializable。
  • 在 PrimeFaces 展示中，有几个Serializable视图范围的 bean 具有不可序列化的服务属性，例如CarService在LazyView惰性数据表演示页面后面的支持 bean。
  • Payara Micro 似乎没有考虑 WAR 自己web.xml是否<distributable>设置了标志。如果未设置此标志，则容器不应假定 WAR 是可分发的。

当您完全删除 OmniFaces，但在 PrimeFaces 展示中设置<distributable>标志时，PrimeFaces 6.0 和 PrimeFaces 展示的相同序列化问题是可重现web.xml的。这些问题中的每一个都需要单独报告。我至少已将PhaseInfo此事报告为问题 1570 ，并在您的 Payara Micro 问题上发表了评论。

在一个稍微相关的说明中，我还注意到 PrimeFaces 展示web.xml已将 Mojarra-specific 设置 com.sun.faces.serializeServerState为false. 我没有调查设置回 时的效果true，但不建议使用此设置，false因为它可能会隐藏与视图构建和状态管理相关的其他错误。
