spring4.2.2整合webflow2.4,真是項目中的實戰經驗

最近由於集團項目架構太老了,然後全國都在調用,沒辦法,老的流程還得保留,經商量,決定吧框架新搭建一套,老框架採用spring2,0webflow是1.0

新框架採用的springmvc+mybais架構.spring採用的4.2.2版本webflow採用的2.4版本的,但是這是個坑,2.4的webflow跟之前的用法很多地方做了改變,

而且網上好多都是在講述1.0的用法,關於webflow2.4的屈指可數,而且有的也是簡單的配置了一下流程,.

無奈自己研究,看源碼 ,然後猜着去嘗試,

首先看下login.xml的配置

<?xml version="1.0" encoding="UTF-8"?>
<flow xmlns="http://www.springframework.org/schema/webflow"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="
              http://www.springframework.org/schema/webflow
     	 http://www.springframework.org/schema/webflow/spring-webflow-2.0.xsd">
<!-- .doExecute(flowRequestContext) -->
	<action-state id="initialFlowSetup">
		<evaluate expression="initialFlowSetupAction"/>
		<transition on="submit"	to="submit" />
		<transition on="createOneTimePassword"	to="createOneTimePassword" />
		<transition on="viewLoginForm" to="viewLoginForm" />
		<transition on="warn" to="showWarningView" />
		<transition on="error" to="viewLoginForm" />
		<transition on="gateway" to="redirectView" />
		<transition on="viewGenericLoginSuccess" to="viewGenericLoginSuccess" />
		<transition on="redirect" to="redirectView" />	
	</action-state>

	

	<view-state id="viewLoginForm" view="casLoginView">
		<on-render>

<!-這是一個表達式,一定要指明你的方法名.並且要傳參,不要寫on-start->
			<evaluate expression="authenticationViaFormAction.setupForm(flowRequestContext)"  />
			<evaluate expression="authenticationViaFormAction.referenceData(flowRequestContext)" />
		</on-render>
		<transition on="submit" to="bindAndValidate" />
	</view-state>
</flow>

剛開始配置的時候一直卡在on-start哪裏不知道怎麼轉到action-start

後來也是大膽的嘗試,將on-start直接幹掉.你媽竟然好了.

spring-mvc.xml配置,此處爲springmvc與webflow整合之重點

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xmlns:p="http://www.springframework.org/schema/p" 
     xmlns:context="http://www.springframework.org/schema/context" 
     xmlns:webflow="http://www.springframework.org/schema/webflow-config" 
     xsi:schemaLocation=" 
          http://www.springframework.org/schema/aop   
          http://www.springframework.org/schema/aop/spring-aop-4.2.xsd  
          http://www.springframework.org/schema/beans   
          http://www.springframework.org/schema/beans/spring-beans-4.2.xsd  
          http://www.springframework.org/schema/webflow-config 
          http://www.springframework.org/schema/webflow-config/spring-webflow-config-2.0.xsd">
	     
  	 <bean id="casPropertyPlaceholderConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
			<property name="location" value="classpath:uam.properties"></property>
		</bean>
		
	 <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">  
	    <property name="supportedMediaTypes">  
	        <list>  
	            <value>text/html;charset=UTF-8</value>  
	        </list>  
	    </property>  
	</bean> 

<!-我的頁面都是通過在properties文件中取得的路徑,所以這裏的的視圖解析器我配置的不大一樣->
	<bean id="viewResolver"
		class="org.springframework.web.servlet.view.ResourceBundleViewResolver"
		p:order="0">
		<property name="basenames">
			<list>
				<value>${uam.viewResolver.basename}</value>
				<value>protocol_views</value>
			</list>
		</property>
	</bean>
	
	 
    <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
	
	<!-- webflow配置 --> 
	<bean name="flowController" class="org.springframework.webflow.mvc.servlet.FlowController">
        <property name="flowExecutor" ref="flowExecutor"/>
    </bean>	   
    <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="mappings">
            <props>

<!-此處有坑.我不加後綴的話此處攔截不到->
                <prop key="/login.do">flowController</prop>
            </props>
        </property>
    </bean>      
	<webflow:flow-executor id="flowExecutor" /> 	   
    <webflow:flow-registry id="flowRegistry" flow-builder-services="flowBuilderServices">
        <webflow:flow-location path="/WEB-INF/login-webflow.xml" id="login" />
    </webflow:flow-registry>      
    <webflow:flow-builder-services id="flowBuilderServices" view-factory-creator="mvcViewFactoryCreator" />    
    <bean id="mvcViewFactoryCreator" class="org.springframework.webflow.mvc.builder.MvcViewFactoryCreator">
        <property name="viewResolvers" ref="viewResolver" />
    </bean> 
 </beans>

最後還是你媽報錯,發現原來webflow中可以獲取request和response現在2.4的已經略去此功能,於是採用filter+threadLocal的方式獲取
