This article proposes a framework for managing object instances in J2EE applications.
就像在传统面向对象编程中实现的那样，这些关注点是作为单独的实例处理的，有可能在应用程序类中产生互不相关的代码(就是混乱)。
As implemented in traditional object-oriented programming, these concerns are handled as individual instances, introducing potentially unrelated code (that is, clutter) into application classes.
我们将此对象的范围设置为application，因为每个应用程序只需要一个此对象的实例。
We set the scope of this object to application, as only one instance is needed per application.

As you would expect, the server MBean represents the management object for an application server, which could be a standalone instance or a member of a cluster.
Distributed map类是应用程序所使用的编程接口，该类允许应用程序从缓存实例获得对象和将对象放置到其中，并可以使其失效。
The DistributedMap interface is the programming interface that your applications work with, enabling the application to get and put objects into the cache instance, as well as invalidate them.
此类提供了一组类或一组单例（singleton）对象实例，在一个JAX-RS应用程序内包括所有的根级别的资源和提供程序（由 @Provider注释的类）。
This class provides a set of classes, or a set of singleton object instances, that include all of the root-level resources and providers (classes annotated with @Provider) in a JAX-RS application.

在进行了远程或其他代价高昂的调用之后，可以将结果存储到应用程序对象的实例变量或者WebSphereDynamicCache映射中，然后在以后调用时重用该结果。
After making a remote or other expensive call, store the result in an instance variable on the application object or in a WebSphere Dynamic Cache map; then, reuse that result on later calls.
