这时，我们已经隐式地在应用服务器中创建了一个消息引擎(图15)。

At this point, we have now implicitly created a message engine inside the application server (Figure 15).

注意：如果消息引擎是重启的应用服务器的一部分，那么它也将重启。

Note: If your messaging engine is part of the application server that is being restarted, it will restart also.

当应用服务器成为总线的成员时，总线就自动配置了一个消息引擎来在应用服务器内实现其功能性。

When an application server becomes a member of a bus, it automatically gets configured with a message engine that implements bus functionality inside the application server.
