问题用的Spring bean从JSF管理的bean

Question

我有web应用程序至极使用JSF 2.0和3.0春天的 问题是：使用依赖注入 有我的配​​置文件JSF管理bean不能用春豆：

web.xml中：

<web-app> 
<display-name>Archetype Created Web Application</display-name> 

<!-- Faces Servlet --> 
<servlet> 
    <servlet-name>Faces Servlet</servlet-name> 
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> 
    <load-on-startup> 1 </load-on-startup> 
</servlet> 

<!-- Faces Servlet Mapping --> 
<servlet-mapping> 
    <servlet-name>Faces Servlet</servlet-name> 
    <url-pattern>/calc/*</url-pattern> 
</servlet-mapping> 


<context-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value>/WEB-INF/spring-beans.xml</param-value> 
</context-param> 

<listener> 
    <listener-class> 
     org.springframework.web.context.ContextLoaderListener 
    </listener-class> 
</listener> 

faces-config.xml中：

<application> 
    <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver> 
</application> 


<managed-bean> 
    <managed-bean-name>CalcBean</managed-bean-name> 
    <managed-bean-class>timur.org.bean.CalculatorConroller</managed-bean-class> 
    <managed-bean-scope>request</managed-bean-scope> 
    <managed-property> 
     <property-name>hibernateUtil</property-name> 
     <value>#{hibernateUtil}</value> 
    </managed-property> 
</managed-bean> 

弹簧的beans.xml：

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> 
    <property name="driverClassName" value="org.postgresql.Driver"/> 
    <property name="url" value="jdbc:postgresql://localhost/timur"/> 
    <property name="username" value="postgres"/> 
    <property name="password" value="postgres"/> 
</bean> 

<bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> 
    <property name="dataSource" ref="dataSource"/> 
</bean> 

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> 
    <property name="dataSource" ref="dataSource"/> 
    <property name="mappingResources"> 
     <list> 
      <value>/mapping/service.xml</value> 
      <value>/mapping/city.xml</value> 
      <value>/mapping/timurovec.xml</value> 
      <value>/mapping/client.xml</value> 
      <value>/mapping/calendar.xml</value> 
      <value>/mapping/order.xml</value> 
     </list> 
    </property> 
    <property name="hibernateProperties"> 
     <props> 
      <prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop> 
      <prop key="show_sql">true</prop> 
      <prop key="hibernate.hbm2ddl.auto">create</prop> 
     </props> 
    </property> 

</bean> 

<bean id="hibernateUtil" class="timur.org.util.HibernateUtil"> 
    <property name="sessionFactory" ref="sessionFactory"></property> 
</bean> 

<tx:annotation-driven transaction-manager="txManager"></tx:annotation-driven> 

CalculateController：

public class CalculatorConroller { 

private HibernateUtil hibernateUtil; 


public void setHibernateUtil(HibernateUtil hibernateUtil) { 
    this.hibernateUtil = hibernateUtil; 
} 

public String action() { 

    hibernateUtil.createAndStoreEvent("",new Date()); 
    List<CityDomain> lc = hibernateUtil.getList(); 
    for (int i=0; i<lc.size(); i++){ 
     LogManager.getLogger(this.getClass()).debug(lc.get(i).getName()); 
    } 

    return "success"; 
} 

}

当我运行我的Web应用程序，并调用我的控制器动作变量 '的HibernateUtil' 是null并且没有例外。但我可以得到春豆使用：

 hibernateUtil = (HibernateUtil) FacesContextUtils.getWebApplicationContext(FacesContext.getCurrentInstance()).getBean("hibernateUtil"); 

我怎样才能得到这个春天豆使用依赖注入？

Answer 1

为什么你不在spring-beans.xml中声明你的面孔管理bean？

也许你还需要在你的脸上，配置补充一点：

<application> 
    <view-handler>com.sun.facelets.FaceletViewHandler</view-handler> 
    <variable-resolver>org.springframework.web.jsf.DelegatingVariableResolver</variable-resolver> 
</application> 

我不是百分之百肯定这虽然是因为我现在在我的工作站我不是。但我认为它必须像上面那样。

那么你只需将你的“CalcBean”移动到spring-beans.xml并像以前一样使用它。

Answer 2

你缺少的是JSF依赖注入了解Spring及其bean的方法。只需将其添加到您的faces-config.xml：

<application> 
    <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver> 
</application> 

Answer 3

非常感谢您的回答。 这是我的问题的解决方案： 我改变行：

<el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver> 

到：

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

，但它不一定是加CalculatorBean春天-beans.xml文件 感谢

Answer 4

org.springframework.web.jsf.el.SpringBeanFacesELResolver是有问题的。这篇文章（http://www.beyondjava.net/blog/integrate-jsf-2-spring-3-nicely/）提出了一个更好的解决方案。
