HandlerExecutionChain request -> executionchain
// RequestMappingHandlerMappingHandlerMapping, 找到第一个能处理的HandlerMapping
1 2 3 4 5 6 7 8 9 10 11 12 13 protected HandlerExecutionChain getHandler (HttpServletRequest request) throws Exception for (HandlerMapping hm : this .handlerMappings) { if (logger.isTraceEnabled()) { logger.trace( "Testing handler map [" + hm + "] in DispatcherServlet with name '" + getServletName() + "'" ); } HandlerExecutionChain handler = hm.getHandler(request); if (handler != null ) { return handler; } } return null ; }
handlerMappings的值默认是:
1 2 3 this.handlerMappings = {ArrayList@5980} size = 2 0 = {RequestMappingHandlerMapping@5997} 1 = {BeanNameUrlHandlerMapping@6002}
org.springframework.web.servlet.handler.AbstractHandlerMapping#getHandler
executionchain就是interceptor和实际处理方法的结合体
映射关系 url -> HandlerMethod
org.springframework.web.servlet.handler.AbstractHandlerMethodMapping#getHandlerInternal
HandlerMethod是具体的controller对应的方法.
1 2 3 4 5 mappingLookup = {LinkedHashMap@6069} size = 4 0 = {LinkedHashMap$Entry@6077} "{[/async]}" -> "public java.util.concurrent.Callable<java.lang.String> com.air.mvc.AsyncController.asyncProcess()" 1 = {LinkedHashMap$Entry@6078} "{[/asyncV2]}" -> "public org.springframework.web.context.request.async.DeferredResult<java.lang.String> com.air.mvc.AsyncController.aysncProcess2()" 2 = {LinkedHashMap$Entry@6079} "{[/mvc/echo]}" -> "private java.lang.String com.air.mvc.SampleController.echo(javax.servlet.http.HttpServletRequest)" 3 = {LinkedHashMap$Entry@6080} "{[/mvc/test]}" -> "private java.lang.String com.air.mvc.SampleController.echo(java.lang.String)"
interceptor url -> interceptors
1 2 3 4 5 6 7 8 9 10 11 12 13 String lookupPath = this .urlPathHelper.getLookupPathForRequest(request); for (HandlerInterceptor interceptor : this .adaptedInterceptors) { if (interceptor instanceof MappedInterceptor) { MappedInterceptor mappedInterceptor = (MappedInterceptor) interceptor; if (mappedInterceptor.matches(lookupPath, this .pathMatcher)) { chain.addInterceptor(mappedInterceptor.getInterceptor()); } } else { chain.addInterceptor(interceptor); } }
HandlerAdapter HandlerMethod -> HandlerAdapter
// RequestMappingHandlerAdapter
遍历所有的HandlerAdapters, 找到第一个能处理的HandlerAdapter
1 2 3 4 5 6 7 8 9 10 11 12 protected HandlerAdapter getHandlerAdapter (Object handler) throws ServletException for (HandlerAdapter ha : this .handlerAdapters) { if (logger.isTraceEnabled()) { logger.trace("Testing handler adapter [" + ha + "]" ); } if (ha.supports(handler)) { return ha; } } throw new ServletException("No adapter for handler [" + handler + "]: The DispatcherServlet configuration needs to include a HandlerAdapter that supports this handler" ); }
默认的HandlerAdapters
1 2 3 4 this.handlerAdapters = {ArrayList@5983} size = 3 0 = {RequestMappingHandlerAdapter@4845} 1 = {HttpRequestHandlerAdapter@6268} 2 = {SimpleControllerHandlerAdapter@6269}
涉及到的请求处理:
a. org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter#invokeHandlerMethod
调用对应的controller方法
b. org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter#getModelAndView
返回模型和视图
ServletInvocableHandlerMethod HandlerMethod -> ServletInvocableHandlerMethod
org.springframework.web.servlet.mvc.method.annotation.ServletInvocableHandlerMethod#invokeAndHandle
a. InvocableHandlerMethod#invokeForRequest
1. 解析传递的参数, 必要时进行转换(resolver负责映射输入的参数名称和controller方法对应的参数, dataBinder负责类型转换和校验)
2. 反射调用对应的方法
b. returnValueHandlers#handleReturnValue
从所有的handler中找到第一个支持对应返回值类型的处理返回值, 可能涉及`HttpMessageConverter`
