]]>jsf-Managed Beans -Beans 上的 List、Map http://www.blogjava.net/zhouxing/archive/2008/05/26/BeanWithListMap.html周行周行Mon, 26 May 2008 04:39:00 GMThttp://www.blogjava.net/zhouxing/archive/2008/05/26/BeanWithListMap.htmlhttp://www.blogjava.net/zhouxing/comments/202880.htmlhttp://www.blogjava.net/zhouxing/archive/2008/05/26/BeanWithListMap.html#Feedback0http://www.blogjava.net/zhouxing/comments/commentRss/202880.htmlhttp://www.blogjava.net/zhouxing/services/trackbacks/202880.html如果您的Bean上有接受List或Map型態的屬性，則您也可以在組態檔案中直接設定這些屬性的值，一個例子如下：
 

....

<managed-bean>

<managed-bean-name>someBean</managed-bean-name>

<managed-bean-class>

onlyfun.caterpillar.SomeBean

</managed-bean-class>

<managed-bean-scope>session</managed-bean-scope>



<managed-property>

<property-name>someProperty</property-name>

<list-entries>

<value-class>java.lang.Integer</value-class>

<value>1</value>

<value>2</value>

<value>3</value>

</list-entries>

</managed-property>

</managed-bean>

....

 

這是一個設定接受List型態的屬性，我們使用<list-entries>標籤指定將設定一個List物件，其中<value-class>指定將存入List的型態，而<value>指定其值，如果是基本型態，則會嘗試使用指定的 <value-class>來作Wrapper類別。

 

設定Map的話，則是使用<map-entries>標籤，例如：
 

....

<managed-bean>

<managed-bean-name>someBean</managed-bean-name>

<managed-bean-class>

onlyfun.caterpillar.SomeBean

</managed-bean-class>

<managed-bean-scope>session</managed-bean-scope>



<managed-property>

<property-name>someProperty</property-name>

<map-entries>

<value-class>java.lang.Integer</value-class>

<map-entry>

<key>someKey1</key>

<value>100</value>

</map-entry>

<map-entry>

<key>someKey2</key>

<value>200</value>

</map-entry>

</map-entries>

</managed-property>

</managed-bean>

....

 

由於Map物件是以key-value對的方式來存入，所以我們在每一個<map-entry>中使用<key>與< value>標籤來分別指定。

 

您也可以直接像設定Bean一樣，設定一個List或Map物件，例如在JSF附的範例中，有這樣的設定：
 

....

<managed-bean>

<description>

Special expense item types

</description>

<managed-bean-name>specialTypes</managed-bean-name>

<managed-bean-class>

java.util.TreeMap

</managed-bean-class>

<managed-bean-scope>application</managed-bean-scope>

<map-entries>

<value-class>java.lang.Integer</value-class>

<map-entry>

<key>Presentation Material</key>

<value>100</value>

</map-entry>

<map-entry>

<key>Software</key>

<value>101</value>

</map-entry>

<map-entry>

<key>Balloons</key>

<value>102</value>

</map-entry>

</map-entries>

</managed-bean>

....

 

而範例中另一個設定List的例子如下：
 

....

<managed-bean>

<managed-bean-name>statusStrings</managed-bean-name>

<managed-bean-class>

java.util.ArrayList

</managed-bean-class>

<managed-bean-scope>request</managed-bean-scope>

<list-entries>

<null-value/>

<value>Open</value>

<value>Submitted</value>

<value>Accepted</value>

<value>Rejected</value>

</list-entries>

</managed-bean>

....

]]>jsf-Managed Beans-Beans 的組態與設定 http://www.blogjava.net/zhouxing/archive/2008/05/26/ConfigBeans.html周行周行Mon, 26 May 2008 04:37:00 GMThttp://www.blogjava.net/zhouxing/archive/2008/05/26/ConfigBeans.htmlhttp://www.blogjava.net/zhouxing/comments/202879.htmlhttp://www.blogjava.net/zhouxing/archive/2008/05/26/ConfigBeans.html#Feedback0http://www.blogjava.net/zhouxing/comments/commentRss/202879.htmlhttp://www.blogjava.net/zhouxing/services/trackbacks/202879.html 
 

<web-app>

<context-param>

<param-name>javax.faces.CONFIG_FILES</param-name>

<param-value>/WEB-INF/beans.xml</param-value>

</context-param>



...

</web-app>

 

定義檔可以有多個，中間以 "," 區隔，例如：
 

/WEB-INF/navigation.xml,/WEB-INF/beans.xml

 

一個Bean最基本要定義Bean的名稱、類別與存活範圍，例如：
 

....

<managed-bean>

<managed-bean-name>user</managed-bean-name>

<managed-bean-class>

onlyfun.caterpillar.UserBean

</managed-bean-class>

<managed-bean-scope>session</managed-bean-scope>

</managed-bean>

....

 

如果要在其它類別中取得Bean物件，則可以先取得javax.faces.context.FacesContext，它代表了JSF目前的執行環境物件，接著嘗試取得javax.faces.el.ValueBinding物件，從中取得指定的Bean物件，例如：
 

FacesContext context = FacesContext.getCurrentInstance();

ValueBinding binding = 

context.getApplication().createValueBinding("#{user}");

UserBean user = (UserBean) binding.getValue(context);

 

如果只是要嘗試取得Bean的某個屬性，則可以如下：
 

FacesContext context = FacesContext.getCurrentInstance();

ValueBinding binding = 

context.getApplication().createValueBinding(

"#{user.name}");

String name = (String) binding.getValue(context);

 

如果有必要在啟始Bean時，自動設置屬性的初始值，則可以如下設定：
 

....

<managed-bean>

<managed-bean-name>user</managed-bean-name>

<managed-bean-class>

onlyfun.caterpillar.UserBean

</managed-bean-class>

<managed-bean-scope>session</managed-bean-scope>

<managed-property>

<property-name>name</property-name>

<value>
