Tomcat xml配置文件

 

Server服务器管理多个Service服务，每个Service服务包括Connector、Container、Jasper、Naming、Session等；Container对应多个Connector。

Server下面有GlobalNamingResources/Listener/Service;GlobalNamingResources下面有Resources

Service下面有Executor /Connector/Engine ;其中Connector 可以包含Executor属性；

Engine下面有Cluster /Realm /Host ;其中Host 可以有Value属性；
