对象（资源）池是一种设计模式。

Tomcat中没有一个连接池， 定义多个池。然后，您可以通过服务提供者作为全局服务器，服务，引擎，主机或只是一个上下文。应用程序查找连接池，服务提供程序确保保留定义的规则。

There is not a single Connection pool in Tomcat, instead it allows you to define multiple pools. You then control the scope and access to each pool via a service provider as either the global server, a service, an engine, a host or just a single context. The application looks up connection pool and the service provider ensures the defined rules are upheld.
