+# Spring MVC运行时序图分析
+
+
+### 运行时序图
+见spring mvc运行时序图
+### 原理分析
+
+主要围绕着DispatcherServlet类来执行的
+![](https://img-blog.csdn.net/20180522162744760?watermark/2/text/aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3lhbndlaWhwdQ==/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70)
+
+DispatcherServlet类中的属性beans：
+
+HandlerMapping：用于handlers映射请求和一系列的对于拦截器的前处理和后处理，大部分用@Controller注解。
+
+HandlerAdapter：帮助DispatcherServlet处理映射请求处理程序的适配器，而不用考虑实际调用的是 哪个处理程序。
+
+HandlerExceptionResolver：处理映射异常。
+
+ViewResolver：根据实际配置解析实际的View类型。
+
+LocaleResolver：解决客户正在使用的区域设置以及可能的时区，以便能够提供国际化视野。
+
+ThemeResolver：解决Web应用程序可以使用的主题，例如提供个性化布局。
+
+MultipartResolver：解析多部分请求，以支持从HTML表单上传文件。
+
+FlashMapManager：存储并检索可用于将一个请求属性传递到另一个请求的input和output的FlashMap，通常用于重定向。
+
+在Web MVC框架中，每个DispatcherServlet都拥自己的WebApplicationContext，它继承了ApplicationContext。WebApplicationContext包含了其上下文和Servlet实例之间共享的所有的基础框架beans。
+
+通过doService方法设置了request的相关属性，然后调用doDispatch方法
+```java
+protected void doDispatch(HttpServletRequest request, HttpServletResponse response) throws Exception {
+        HttpServletRequest processedRequest = request;
+        HandlerExecutionChain mappedHandler = null;
+        boolean multipartRequestParsed = false;
+        WebAsyncManager asyncManager = WebAsyncUtils.getAsyncManager(request);
+
+        try {
+            try {
+                ModelAndView mv = null;
+                Object dispatchException = null;
+
+                try {
+                    processedRequest = this.checkMultipart(request);
+                    multipartRequestParsed = processedRequest != request;
+                    mappedHandler = this.getHandler(processedRequest);
+                    if (mappedHandler == null) {
+                        this.noHandlerFound(processedRequest, response);
+                        return;
+                    }
+
+                    HandlerAdapter ha = this.getHandlerAdapter(mappedHandler.getHandler());
+                    String method = request.getMethod();
+                    boolean isGet = "GET".equals(method);
+                    if (isGet || "HEAD".equals(method)) {
+                        long lastModified = ha.getLastModified(request, mappedHandler.getHandler());
+                        if ((new ServletWebRequest(request, response)).checkNotModified(lastModified) && isGet) {
+                            return;
+                        }
+                    }
+
+                    if (!mappedHandler.applyPreHandle(processedRequest, response)) {
+                        return;
+                    }
+
+                    mv = ha.handle(processedRequest, response, mappedHandler.getHandler());
+                    if (asyncManager.isConcurrentHandlingStarted()) {
+                        return;
+                    }
+
+                    this.applyDefaultViewName(processedRequest, mv);
+                    mappedHandler.applyPostHandle(processedRequest, response, mv);
+                } catch (Exception var20) {
+                    dispatchException = var20;
+                } catch (Throwable var21) {
+                    dispatchException = new NestedServletException("Handler dispatch failed", var21);
+                }
+
+                this.processDispatchResult(processedRequest, response, mappedHandler, mv, (Exception)dispatchException);
+            } catch (Exception var22) {
+                this.triggerAfterCompletion(processedRequest, response, mappedHandler, var22);
+            } catch (Throwable var23) {
+                this.triggerAfterCompletion(processedRequest, response, mappedHandler, new NestedServletException("Handler processing failed", var23));
+            }
+
+        } finally {
+            if (asyncManager.isConcurrentHandlingStarted()) {
+                if (mappedHandler != null) {
+                    mappedHandler.applyAfterConcurrentHandlingStarted(processedRequest, response);
+                }
+            } else if (multipartRequestParsed) {
+                this.cleanupMultipart(processedRequest);
+            }
+
+        }
+    }
+```
+通过handlerMapping获得Handler，然后生成对应的HandlerAdapter来处理数据逻辑（controller层），获得了一个ModelAndView对象。HandlerAdpater 处理的结果是创建了一个ModelAndView对象，但不代表这个ModelAndView对象中包含了完整的信息。  随后DispatcherServlet使用RequestToViewNameResolver给ModelAndView设置viewName。最后调用processDispatchResult来处理界面逻辑（异常和view层）。
+### 总结
+
+几个组件之间的执行流程是    handlerMapping  ———> handlerAdapter———>requestToViewNameResolver ———>handlerExceptionResolver———>viewResolver———>View
