springmvc组件HandlerAdapter源码分析-SimpleControllerHandlerAdapter

1.springmvc中SimpleControllerHandlerAdapter继承体系

2.概述

SimpleControllerHandlerAdapter处理实现了Controller接口的处理器，处理请求直接调用Controller接口的handleRequest方法

3.SimpleControllerHandlerAdapter源码

4.请求处理

实现了HandlerAdapter的supports方法，如果处理器是Controller接口的子类进行处理

	@Override
	public boolean supports(Object handler) {
		return (handler instanceof Controller);
	}

实现了HandlerAdapter的handle方法，直接强转HttpRequestHandler接口调用handleRequest方法，返回ModelAndView

@Override
	@Nullable
	public ModelAndView handle(HttpServletRequest request, HttpServletResponse response, Object handler)
			throws Exception {

		return ((Controller) handler).handleRequest(request, response);
	}
