Question

我在採用以下方式配置兩個流：

<?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"> 
    <on-start> 
     <evaluate expression="mytService.createUserForm()" result="flowScope.userForm" /> 
    </on-start> 

    <view-state id="register" view="account/registerForm" model="userForm">  
     <on-render> 
      <set name="requestScope.countryList" value="mytService.getCountryList()" /> 
     </on-render> 
     <transition on="submitRegistration" to="addAccount" bind="true" validate="true" /> 
     <transition on="cancelRegistration" to="cancelRegistration" 
      bind="false" /> 
    </view-state> 

    <view-state id="accountAdded" view="account/registeringForm"> 
     <transition on="sendOnceAgain" to="registering"> 
      <evaluate expression="myService.sendOnceAgain()"></evaluate> 
     </transition> 
    </view-state> 

    <action-state id="addAccount"> 
     <evaluate expression="myService.addAccount(userForm)" /> 
     <transition to="accountAdded" /> 
    </action-state> 

    <end-state id="cancelRegistration" view="externalRedirect:contextRelative:/home.do" /> 

    <global-transitions> 
     <transition on="changeLang"> 

     </transition> 
    </global-transitions> 
</flow> 

和：

<?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"> 

    <input name="hash" required="true"/> 

    <on-start> 
     <evaluate expression="myService.createUserForm()" result="flowScope.userForm" /> 
    </on-start> 

    <action-state id="decideAction"> 
     <set name="flowScope.goTo" value ="mytService.verifyHash(hash)" /> 
     <transition to="${goTo}"></transition> 
    </action-state> 

    <view-state id="correctVerify" view="account/registeredForm" model="userForm"> 
     <transition on="addPhoneNumber" to="correctVerify"> 
      <evaluate expression="myService.addPhoneNumber(userForm)" /> 
     </transition> 
     <transition on="deletePhoneNumber" to="correctVerify"> 
      <evaluate expression="myService.deletePhoneNumber(userForm, requestParameters.deleteNumber)" /> 
     </transition> 
    </view-state> 

    <view-state id="notCorrectVerify" view="account/registerForm"> 

    </view-state> 

    <view-state id="start"> 
    </view-state> 


    <global-transitions> 
     <transition on="changeLang">  
     </transition> 
    </global-transitions> 
</flow> 

我也有改變語言組合。我的問題是如何實現語言的變化？如何改變語言？

<div id="header"> 
    <div id="left"> 
     <div id="logo"></div> 
    </div> 
    <div id="right"> 
     <ul> 
      <li class="helpLink"><a href="#">Pomoc</a></li> 
      <li class="langSelect"> 
      <form id="langForm" action="${flowExecutionUrl}&_eventId=changeLang" method="post"> 
       <input type="hidden" value="${execution}" name="execution" /> 
       <select name="lang" id="lang" class="styled" onchange="this.form.submit()"> 
        <option value="pl" ${sessionScope.lang == 'pl' ? 'selected' : ''} >PL</option> 
        <option value="en" ${sessionScope.lang == 'en' ? 'selected' : ''} >EN</option> 
       </select> 
      </form> 
      </li> 
     </ul> 
    </div> 
</div>

Answer 1

的LocaleChangeIntercepter會做的伎倆。

您已經配置了它。

要了解更多詳情，請參閱Spring Reference章節15.6 Using locales。

如果你想看到它的行動，建立一個小的春季roo應用程序，並添加第二種語言。然後你可以瀏覽源代碼添加看看他們（Roo）是如何做到的。

Answer 2

我要說的是Spring Web Flow的不是處理具體的語言環境的觀點的正確途徑。退房視圖處理和國際化：
