我可以使用 PrimeFaces 6.0 Showcase 重现异常，所以看起来原因不在我的代码中。
这是使用 PrimeFaces showcase 重现的方法：
从 github 下载 PrimeFaces 6.0 showcase 个来源。
将 OnmiFaces 依赖项添加到 pom.xml:
<dependency>
<groupId>org.omnifaces</groupId>
<artifactId>omnifaces</artifactId>
<version>2.3</version>
</dependency>
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
用mvn package构建然后用java -jar showcase-6.0.jar
现在在本地主机上启动 showcase 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，而只会发生在 Payara Micro 上。
所以我不确定错误是在 OmniFaces、Payara Micro、PrimeFaces 还是其他地方。
此行为是由 <distributable> 标志引起的，该标志是 added 到 OmniFaces 2.1 以在集群上支持 运行。
这又发现了 PrimeFaces 6.0、PrimeFaces 展示应用程序和 Payara Micro 中的一些错误。
- PrimeFaces 6.0 新
PhaseInfo class implements Serializable, but has a PhaseId 属性 根本不是 Serializable。
- 在 PrimeFaces 展示中有几个
Serializable 视图范围 bean 具有不可序列化的服务 属性 例如 CarService in LazyView 惰性数据后面的支持 bean table 演示页面.
- Payara Micro 似乎没有考虑 WAR 自己的
web.xml 是否设置了 <distributable> 标志。如果未设置此标志，则容器不应将 WAR 假定为 distributable.
当您完全删除 OmniFaces 但在 PrimeFaces 展示柜的 web.xml 中设置 <distributable> 标志时，与 PrimeFaces 6.0 和 PrimeFaces 展示柜的序列化问题非常相同。这些问题中的每一个都需要单独报告。我至少已将 PhaseInfo 问题报告为 issue 1570 and posted a comment 关于您的 Payara Micro 问题。
稍微相关一点，我还注意到 PrimeFaces 展示的 web.xml 已将 Mojarra 特定的 com.sun.faces.serializeServerState 设置为 false。我没有研究设置回 true 时的效果，但是 false 的设置 不推荐 因为它可能隐藏与视图构建和状态相关的其他错误管理。
