Embedded tomcat的基础组组件接口

工厂方法

LifecycleMBeanBase

略

继承了LifecycleBase基类的基础上，实现了JmxEnable和MBeanRegistration接口的JMX功能

双向关联

StandardService

- server:Server = null- connectors:Connector[] =new Connector[0]- engine: Engine = null- executors: Array<Executor> = new ArrayList<>();

+ setServer(Server):void+ setContainer(Engine):void+ addConnector(Connector):void+ addExecutor(Executor):void+get...

LifecycleBase

- sm:StringManager =               StringManager.getManager(...)- lifecycleListener:List<LifecycleListener>=          new CopyOnWriteList<>()- state: LifecycleState =                 LifecycleState.NEW

+init():void+start():void+stop():void+destroy():void+addLifecycleListener(LifecycleListener)+getState:LifeState

TomcatServletWebServerFactory

JDK的JMX接口

<<接口>>Engine

+ setService(Service):void+ setDefaultHost(String): void+setJvmRoute(String): void+get...以及继承自Container的方法，尤其是addChild方法

<<接口>>Container

+ addChild(Container):voidfont color=\"#323232\

<<接口>>MBeanRegistration

+preRegister+postRegister+preDeregister+postDeregister

<<接口>>ServletContextInitializer

+ onStartup(servletContext):void

来自spring-boot-2.1.0.Release-sources兼容层的类，其他都是Embedded Tomcat和JDK包的类

StandardContext

- context:ApplicationContext = null- applicationListeners: String[] = new String[0];- resources:WebResourceRoot- useHttpOnly: boolean =true-cookieProcessor:CookieProcessor-requestEncoding: String = null-responseEncoding: String = null...以及继承自ContainerBase的属性

实现了Context接口的方法以及继承自ContainerBase的方法

TomcatEmbeddedContext

- starter:TomcatStarter 以及从StandardContext和ContainerBase、LifecycleMBeanBase继承的属性

<<接口>>Lifecycle

<<接口>>Service

+ setServer(Server):void+ setContainer(Engine):void+ addConnector(Connector):void+ addExecutor(Executor):void+getContainer():Engine......

TomcatWebServer

- tomcat: Tomcat

+ TomcatWebServer(Tomcat)+ start():void+ stop():void+ getPort():int

ContainerBase

+ addChild(Container):void+setParent(Container):void+addContainerListener(ContainerListener):voidfont color=\"#323232\

StandardEngine

+ defaultHost: String = null+ service:Service = null+ jvmRouted:String以及继承自ContainerBase的属性

+ setService(Service):void+ setDefaultHost(String): void+setJvmRoute(String): void+get...以及继承自ContainerBase的API

StandardServer

- port: int = 8005- address: String=\"localhost\"- services:Service[] = new       Service[0]- catalina: Catalina = null

contains
