1. providerFactory.registerProvider2. providerFactory.registerProviderInstance//provider主要是resteasy.plugins.providers包下的类，可以是自带的，也可以是拓展包，比如resteasy-jackon-provider3. dispatcher.getRegistry().addPerRequestResource4. dispatcher.getRegistry().addSingletonResource//处理@path资源，生成rootSegment及invoker，用于mapping

HttpServletDispatcher

#  servletContainerDispatcher:    ServletContainerDispatcher

实现

ThreadLocalResteasyProviderFactory

-  delegate :  ThreadLocalStack<ResteasyProviderFactory>

+getDelegate()：ResteasyProviderFactory

ApplicationFiterChain

调用ResourceMethod.invoke调用具体业务实现类调用栈：ResourceMethod.invokeMethodInjectorImpl.invokeDelegatingMehodAccessorImpl.invokeNativeMethodAccessorImpl.invoke业务类UserService.getUsers()

处理资源，匹配invokder；ResourceMethod invoker = new ResourceMethod（）// 是Http请求存到ResourceMethod生成invoker；ResourceLocator locator = new ResourceLocator（）// 不是则生成ResourceLocator生成locator

Host

ResourceMethodRegistry

# size：int //共有多少种@path路径# providerFactory：ResteasyProviderFactory # rootSegment：RootSegment 

CoyoteAdapterconnector与容器的桥梁生成给conector使用的req和res调用容器管道

HTTPMethod：GET \\ POST \\ PUT \\ DELETE \\ HEAD \\ OPTIONS

组合

继承

处理拦截器、@Produces
