而不是執行評估表達式，mvc控制器方法正在執行 - Spring Web Flow

我是Spring Web Flow中的newbee。我使用spring web flow創建了一個示例項目。在主頁上，mvc控制器方法按照期望執行併到達第二頁。從第二頁開始，點擊提交一個評估表達式即可執行。而不是先執行的方法再次執行。我可以看到表單上的操作只有$ {flowExecutionUrl}。所以RequestMapping獲得相同的URL。因此執行舊的方法。而不是執行評估表達式，mvc控制器方法正在執行 - Spring Web Flow

是否可以更改操作屬性中的uri，然後附加$ {flowExecutionUrl}。
我們怎樣才能確保流程定義文件被執行

Servlet的context.xml中

<context:annotation-config/> 
    <context:component-scan base-package="com.metlife.claim"/> 
    <bean class= 
"org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/> 
     <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> 
     <property name="mappings"> 
      <value> 
       /claim/=flowController 
      </value> 
     </property> 
     <property name="alwaysUseFullPath" value="true"/> 
    </bean> 
     <bean class= 
"org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/> 
    <bean class= 
"org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/> 
     <bean id="viewResolver" class= 
"org.springframework.web.servlet.view.InternalResourceViewResolver"> 
     <property name="prefix" value="/WEB-INF/views/"/> 
     <property name="suffix" value=".jsp"/> 
    </bean> 
     <bean id="flowController" class= 
"org.springframework.webflow.mvc.servlet.FlowController"> 
     <property name="flowExecutor" ref="flowExecutor"/> 
    </bean> 
     <flow:flow-executor id="flowExecutor" flow-registry="flowRegistry"/> 
     <flow:flow-registry id="flowRegistry" 
      flow-builder-services="flowBuilderServices"> 
     <flow:flow-location path="/WEB-INF/flows/claims-flow.xml"/> 
    </flow:flow-registry> 

    <flow:flow-builder-services id="flowBuilderServices" 
      view-factory-creator="viewFactoryCreator"/> 

    <bean id="viewFactoryCreator" class= 
"org.springframework.webflow.mvc.builder.MvcViewFactoryCreator"> 
     <property name="viewResolvers"> 
      <list> 
       <ref bean="viewResolver"/> 
      </list> 
     </property> 
    </bean> 
</beans>

要求，flow.xml

<?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"> 

    <!-- <view-state id="claims" view="addClaims"> --> 
    <view-state id="claims" model = "viewScope.claim"> 
    <transition to="claimsEntered" on="submit"> 
     <!-- <evaluate expression="claimController.saveNewClaim(viewScope.claim)"></evaluate> --> 
     </transition> 
     </view-state> 
    <action-state id="claimsEntered"> 
    <evaluate expression="claimController.saveNewClaim(viewScope.claim)"></evaluate> 
    <transition to="claims"></transition> 
    </action-state> 
</flow>

ClaimController.java

@Controller 
public class ClaimController { 

    public static List<Claim> claimList = new ArrayList<Claim>(); 

    @RequestMapping(value = "/claims/") 
    public void getClaims(){ 
     System.out.println("Hi Claims"); 
    } 

    public void saveNewClaim(Claim claim){ 
     claimList.add(claim); 
     System.out.println("The claim has been added..."); 
    } 
}

claims.jsp

<form modelAttribute = "claim" action= "${flowExecutionUrl}"> 
<table> 
<tr> 
<td>Id</td> 
<td><input type = "text" path="id" name = "id"/></td> 
<tr> 
<tr> 
<td>Name</td> 
<td><input type = "text" path="id" name = "name"/></td> 
<tr> 
<tr> 
<td>Age</td> 
<td><input type = "text" path="id" name = "age"/></td> 
<tr> 
<tr> 
<td>Amount</td> 
<td><input type = "text" path="id" name = "amount"/></td> 
<tr> 
<tr> 
<td>Region</td> 
<td><input type = "text" path="id" name = "region"/></td> 
<tr> 
<tr> 
<td> 
<input type = "submit" id = "submit" name = "_eventId_submit" value = "Submit"></td></tr> 
</table> 
</form>

針對home.jsp

<body> 
<h1> 
</h1> 
<P> <a href="claims/" >Claims</a> </P> 
</body>

在從claims.jsp提交按鈕的點擊事件，則執行getClaims的ClaimController代替saveNewClaim（（）方法）。

任何人都可以幫忙找出執行過程中出了什麼問題，怎麼才能解決這個問題。在此先感謝

我不確定有關claim-flow.xml，但可以在saveNewClaim方法中使用RequestMapping。

@RequestMapping(value = "/claims/", method = RequestMethod.POST) 
public void saveNewClaim(Claim claim){ 
    claimList.add(claim); 
    System.out.println("The claim has been added..."); 
}

我在想某事像這樣：

@Controller 
public class ClaimController { 

    public static List<Claim> claimList = new ArrayList<Claim>(); 

    @RequestMapping(value = "/claims/", method = RequestMethod.GET) 
    public void getClaims(){ 
     System.out.println("Hi Claims"); 
    } 
    @RequestMapping(value = "/claims/", method = RequestMethod.POST) 
    public void saveNewClaim(Claim claim){ 
     claimList.add(claim); 
     System.out.println("The claim has been added..."); 
    } 
}

第一種方法加載的形式。第二個響應來自此表單的POST請求。

是的。對於Spring MVC，你是對的。如果我們使用值指定RequestMapping，則Web流程不會出現在圖片中 – Mahi
