jsf--页面循环跳转，项目内容递交

在order-flow.xml中：

创建新的managebean:

该位置回头待修改。

此三处做修改

107 
108    
109    
110 }

OrderBean.java

注：

h:表示jsf的html

创建一个表单，flow的入口，取名“order”

在order.xhtml中写入代码：

 1 <?xml version='1.0' encoding='UTF-8' ?>
 2 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 3 <html xmlns="http://www.w3.org/1999/xhtml"
 4       xmlns:h="http://xmlns.jcp.org/jsf/html">
 5     <h:head>
 6         <title>Select item quantity</title>
 7     </h:head>
 8     <h:body>
 9         <h:form>
10             <h:outputText value="Item name:"/>
11             <br/>
12             <h:inputText value="#{orderBean.itemName}"/>
13             <!--将itemname做一对一的绑定-->
14             <br/><br/>
15             <h:outputText value ="Item quantity"/>
16             <br/>
17             <h:inputText value="#{orderBean.itemCount}"/><!--将itemCount做一对一的绑定-->
18             
19              <h:commandButton value="Proceed" action="order-address"/><!--输入地址-->
20              
21         </h:form>
22     </h:body>
23 </html>

order.xhtml

同理，建立order-address.xhtml:

在其中写入代码：

 1 <?xml version='1.0' encoding='UTF-8' ?>
 2 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 3 <html xmlns="http://www.w3.org/1999/xhtml"
 4       xmlns:h="http://xmlns.jcp.org/jsf/html">
 5     <h:head>
 6         <title>Facelet Title</title>
 7     </h:head>
 8     <h:body>
 9          <h:form>
10              <h:outputText value="You are about to order #{orderBean.itemCount}#{orderBean.itemName}"/>
11             <br/>
12             <br/>
13             <h:outputText value ="address:"/>
14             <br/>
15             <h:inputText value="#{orderBean.address}"/>
16             <!--将itemAddress做一对一的绑定-->
17             <br/><br/>
18              <h:commandButton value="Proceed" action="order-confirmation"/><!--下一个页面-->
19              
20         </h:form>
21     </h:body>
22 </html>

order-address.xhml

同理，最后一个，建立order-confirmation.xhtml:

 1 <?xml version='1.0' encoding='UTF-8' ?>
 2 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 3 <html xmlns="http://www.w3.org/1999/xhtml"
 4       xmlns:h="http://xmlns.jcp.org/jsf/html">
 5     <h:head>
 6         <title>order-confirmation</title>
 7     </h:head>
 8     <h:body>
 9         <h:form>
10         <h:outputText value="You have ordered #{orderBean.itemCount}#{orderBean.itemName}"/>
11             <br/>
12         <h:outputText value ="The item will be delivered at :#{orderBean.address}"/>
13           
14             <br/><br/>
15         <h:commandButton value="Eixt" action="returnFromOrderFlow"/><!--结束，退出-->
16     </h:form>
17     </h:body>
18 </html>

order-configuration

输出结果：

解决方法：

注：一定要使用cdibean ,修改如下：
