Spring 尝试在JSF 1.2中加载应用程序上下文时出现NullPointerException

迁移到jsf 1.2时尝试加载应用程序上下文时出现空指针异常

下面是堆栈跟踪

    [ERROR] [com.sun.faces.lifecycle.InvokeApplicationPhase] [] - #   {CustomerSearchBean.searchCustomers}: javax.faces.el.EvaluationException: 
     java.lang.NullPointerException

下面是FacesXML

 <managed-bean>
    <description>This bean is used for customer profile</description>
    <managed-bean-name>CustomerSearchBean</managed-bean-name>
    <managed-bean-class>com.tms.cdqi.presentation.jsf.bean.customerprofile.CustomerSearchBean</managed-bean-class>

@tiny你能告诉我你的建议吗？嗯，看起来像是

这个。getApplicationContextFactory（）

为空。尝试进一步调查这一点。这个方法做什么？@sleske它将调用faces配置文件中的托管bean和属性值，然后加载应用程序contextWell中的bean，然后找出它返回null的原因。我们无法为您调试。@sleske只是想知道您是否知道jsf 1.2如何在托管bean上工作。

       <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns="http://www.springframework.org/schema/beans"
  xsi:schemaLocation="
            http://www.springframework.org/schema/beans
     http://www.springframework.org/schema/beans/spring-beans.xsd">

<bean id="cdqiApplicationContextFactory"
    class="com.tms.cdqi.framework.context.CDQIApplicationContextFactoryImpl" />

    The application context  where null pointer is occurring

    CDQIApplicationContext context = this.getApplicationContextFactory()
            .getApplicationContext();
