Spring bean注入JSF Managed Bean [英] Spring beans injected into JSF Managed Beans

问题描述

问题描述：我注入的Spring bean定义为一个JSF支持bean的Managed-Property没有被实例化。当我检索Managed-Bean时，它总是为null。

我一直在与这一整天战斗，似乎JSF Managed Bean只是不会从Spring读取applicationContext。我可以通过使用FacesContext在支持bean中手动拉出bean，它找到了bean，但是当我尝试通过FacesConfig注入它总是出来null。我包括我的步骤如何我如何集成它。有什么建议么？

配置

Icefaces 1.85

JSF 1.2 （通过冰面servlet）

Spring 3.0

Websphere 7.5（这是eclipse 3.5） p>

Web.xml配置更改

Spring Context Loader侦听器

 < listener> 
< display-name> SpringListener< / display-name> 
< icon> 
< small-icon> small.gif< / small-icon> 
< large-icon> large.gif< / large-icon> 
< / icon> 
< listener-class> org.springframework.web.context.ContextLoaderListener< / listener-class> 
< / listener> 
  

上下文配置

 < context-param> 
< param-name> contextConfigLocation< / param-name> 
< param-value> 
 /WEB-INF/SpringConfig/SpringHelloWorld.xml 
< / param-value> 
< / context-param> 
 





FacesContext变更

变量解析器The Glue

< application>< variable-resolver> org.springframework.web.jsf.DelegatingVariableResolver< / variable-resolver>< / application>

托管Bean

 < managed-bean> 
< managed-bean-name> testData< / managed-bean-name> 
< managed-bean-class> src.test.TestData< / managed-bean-class> 
< managed-bean-scope> session< / managed-bean-scope> 
< managed-property> 
< property-name> spring3HelloWorldBean< / property-name> 
< value>＃{spring3HelloWorldBean}< / value> 
< / managed-property> 
< / managed-bean> 
  

Spring.xml配置

 < bean id =spring3HelloWorldBeanclass =src.test.Spring3HelloWorld/>

解决方案
首先，我认为这个你的问题，DelegatingVariableResolver在1.1之后的所有JSF版本都被弃用，你使用1.2， 
 < application> 
< el-resolver> 
 org.springframework.web.jsf.el.SpringBeanFacesELResolver 
< / el-resolver> 
< / application> 
  
希望它有帮助。
 
Problem Description: My injected Spring bean defined as a Managed-Property to a JSF backing bean is not being instantiated. Its always coming up null when I retreive the Managed-Bean. 

I have been fighting with this all day and it seems that JSF Managed Bean just won't read out of the applicationContext from Spring. I can manually pull out the bean by using the FacesContext in a backing bean and it finds the bean but when I try and inject it through the FacesConfig it always comes out null. I included my steps below how I integrated it. Any suggestions? 

Configuration

Icefaces 1.85

JSF 1.2  (through ice faces servlet)

Spring 3.0

Websphere 7.5 ( Which is eclipse 3.5  I think )

Web.xml Configuration Changes

Spring Context Loader Listener

    <listener>
    <display-name>SpringListener</display-name>
    <icon>
        <small-icon>small.gif</small-icon>
        <large-icon>large.gif</large-icon>
    </icon>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>


Context Config

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/SpringConfig/SpringHelloWorld.xml
    </param-value> 
</context-param>


FacesContext Changes

Variable Resolver - AKA The Glue

<application><variable-resolver>org.springframework.web.jsf.DelegatingVariableResolver</variable-resolver></application>

Managed Bean

   <managed-bean>
    <managed-bean-name>testData</managed-bean-name>
    <managed-bean-class>src.test.TestData</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
    <managed-property>
        <property-name>spring3HelloWorldBean</property-name>
        <value>#{spring3HelloWorldBean}</value>
    </managed-property>
</managed-bean>


Spring.xml Config

<bean id="spring3HelloWorldBean" class="src.test.Spring3HelloWorld" />


Thanks in advance
解决方案
First of all and I think this your problem that DelegatingVariableResolver is deprecated in all JSF version after 1.1 and you are using 1.2 so please use this following configuration.
<application> 
<el-resolver> 
org.springframework.web.jsf.el.SpringBeanFacesELResolver 
</el-resolver> 
</application>
Hope it helps.
