The service endpoint implementation class is derived from the service endpoint interface.

服务端点实现类型是由服务端点接口派生出来的。

youdao

In addition to that interface, this service endpoint implementation class may implement the ServiceLifecycle interface for managing the service's life cycle (see Figure 1).

作为对这个接口的补充，这个服务端点实现类可能实现ServiceLifecycle接口来管理服务的生命周期(请参阅图1)。

youdao

If a service implementation class implements this interface, the JAX-RPC runtime system is required to manage the life cycle of the corresponding service endpoint instances.

如果服务实现类实现这个接口，就需要JAX - RPC运行时系统来管理相应的服务端点实例的生存周期。
