Hazelcast文件的持久性(MapStore实现) [英] Hazelcast file persistence (MapStore implementation)

问题描述

我正在使用Hazelcast进行群集数据分发.我使用MapStore和MapLoader接口阅读了有关数据持久性的文档.我需要实现这些接口，并将类名写在hazelcast.xml文件中.

I am using Hazelcast for clustered data distribution. I read in the documentation about data persistence, using the interfaces MapStore and MapLoader. I need to implement these interfaces and write the class name in the hazelcast.xml file.

是否存在通过hazelcast实现文件持久化的这些接口的实现示例?有人知道我可以下载和使用的任何源代码或jar文件吗?

Is there any example of implementation of these interfaces for file persistence with hazelcast? Does anyone know about any source code or jar file that I can download and work with?

谢谢

推荐答案

只需使用ObjectOutputStream和ObjectInputStream即可实现自己的实现.

You can implement your own just using ObjectOutputStream and ObjectInputStream.

您可以使用地图名称创建目录. store(key，value)操作创建一个名称为key.dat的文件，其中包含序列化值的内容. load(key)方法将"key.dat"文件读入一个对象并返回.

You can create a directory with map's name. store(key, value) operation creates a file with name key.dat, with content of serialized value. load(key) method reads "key.dat" file into an object and returns.

这里有ObjectOutputStream和ObjectInputStream的用法示例

然后，您应该将此实现类添加到您的类路径中，并在hazelcast.xml中进行设置

Then you should add this implementation class to your class path and set it in your hazelcast.xml
