Serialization 如何正确配置全局序列化程序？

我正在尝试为Hazelcast 3.12配置一个全局序列化程序（我的应用程序运行在payara 5上，它与此版本的Hazelcast捆绑在一起，因此我无法更新到4.x）

根据手册（），实现和配置全局序列化程序应该很简单，下面是我的序列化程序：

public class MyGlobalStreamSerializer implements StreamSerializer<Object> {
    private static FSTConfiguration conf = FSTConfiguration.createDefaultConfiguration();

    @Override
    public int getTypeId() {
        return 123;
    }

    @Override
    public void destroy() {
    }

    @Override
    public void write(ObjectDataOutput objectDataOutput, Object o) throws IOException {
        objectDataOutput.write(conf.asByteArray(o));
    }

    @Override
    public Object read(ObjectDataInput objectDataInput) throws IOException {
        return conf.asObject(objectDataInput.readByteArray());
    }
}

在配置中省略包/仅使用类名作为全局序列化程序的值（如手册中所示）也不起作用，我最后一次尝试是使用完整路径，因为这是在版本附带的hazelcast-full-example.xml中完成的

我还看到了另一篇文章，其中有人试图使用Kryo作为实际序列化的实现来实现一个全局序列化程序，代码和配置看起来几乎相同，但他似乎没有我的问题（）

谁能告诉我我做错了什么？提前谢谢

Payara服务器使用自己的序列化程序，无法禁用，请参阅文档：。Payara序列化程序委托给Hazelcast配置中指定的Hazelcast全局序列化程序。这个序列化应该在Payara服务器的类路径中，这还不足以将它添加到应用程序中

尝试将带有

MyGlobalStreamSerializer

及其所有依赖项（例如

fst

JAR及其依赖项）的JAR文件添加到域目录中的

lib

目录中，这会将其添加到服务器的类路径中。以下是

asadmin add library

命令中的文档，您可以使用：

在您的情况下，当Payara服务器想要记录一条消息，表明您的全局序列化程序不是Payara序列化程序所期望的StreamsSerializer的子类时，似乎会引发异常：

该代码在Payara Server 5.2020.x的任何版本中都没有更改，它引发NullPointerException的唯一方法是全局序列化程序为

null

。我预计会发生这种情况，因为Hazelcast找不到序列化程序的类，并为序列化程序返回null
