我正在开发基于Spring,Hibernate和JSF的Web应用程序,并且我面临着一个已经多次讨论过的已知问题。见下文:

我尝试了以下解决方案但没有成功:(:

  • OpenViewInSession过滤器
  • @Transactional annotation
  • 状态,Hibernate.initialize(对象)

我认为我的问题与JSF无关,后者无法获得当前的Hibernate sesssion,但我不知道如何解决这个问题。

我正在使用:

  • JSF 1.2
  • Richfaces 3.3.2
  • Spring 2.5
  • Hibernate 3.2.5
  • JBoss 4.2

在下面找到我的配置文件和源代码:

    <context:include-filter type="regex" expression="com.company.beans.app.*"/>
</context:component-scan>
<context:annotation-config />

Create.xhtml,其中存在导致错误的属性访问:

<rich:comboBox value="#{createProjectBean.project.TPsta.PStat}"id="projectStatus" selectFirstOnUpdate="false"  width="145"
required="true" requiredMessage="#{msg.CMP_requiredPrjStatusError}">
<f:selectItems  value="#{createProjectBean.projectStatusOptions}" />
</rich:comboBox>

知道该怎么做?

答案 0 :(得分:0)

看起来你在'updateModelValuesPhase'中遇到了这个异常,它发生在'invoke application'阶段之前。 “调用应用程序”阶段是您通常执行大部分处理的地方。

如果您正在使用openSessionInView过滤器并仍然收到此异常,则可能是您在上一次请求期间加载了代理,但在当前请求期间尝试访问它。由于代理与已关闭的旧会话相关联,因此会出现LazyInitialization异常。
