对象序列化是实现存储库持久性的一种最简单的方式，原因是datamaprepository类、所包含的数据地图以及它们的元素都是可序列化的。
MBean methods may also use other serializable data types, but doing so can create interoperability issues because the class files must be made available to the JMX client as well.
MBean方法也可以使用其他可以序列化的数据类型，但是这样做会造成互操作性问题，因为类文件也必须对JMX客户机可用。
