我正在研究特定的应用程序，一个spring + hibernate安装程序。我在flex中有一个前端，现在我试图添加一个jstl前端。我得到的延迟初始化异常是当我尝试从jstl模型和视图控制器中调用一个方法时，我从我的flex调用中调用该方法时没有任何问题。spring + jstl + hibernate懒惰初始化异常，如何在Flex前端找到工作
这里是我的web.xml：

这里我打开我的应用程序上下文，这是我理解的负荷从后端，我会用豆子，把我的Hibernate配置和方面的conf igurations。之后，我加载了弹性消息传递servlet，我知道它允许flex和spring进行通信，最后是调度程序servlet，它将把所有的.htm请求映射到jstl控制器和视图。
这里是我的应用程序上下文：

所以我想做的事情，并假设我到现在为止，是共享目录FacadeTarget bean与Flex，并从jstl设置与控制器。因此，我可以调用我从Flex调用相同的方法，现在从控制使用模型和查看方法。我以为这样我就不会遇到任何问题。这里是我的调度员的servlet：
<?xml version="1.0" encoding="UTF-8"?>
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd“>
<!-- URL mapping -->
<bean id="urlMap"
class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="urlMap">
<props>
<prop key="/welcome.htm">welcome</prop>
<prop key="/welcome">welcome</prop>
<prop key="/catalog.htm">catalog</prop>
<prop key="/catalog">catalog</prop>
</props>
</property>
</bean>
<!-- Controllers -->
<bean name="welcome"
class="com.bamboo.catW3.business.impl.Welcome">
<property name="successView">
<value>welcome</value>
</property>
<property name="catalogFacadeImpl" ref="catalogFacadeTarget"/>
</bean>
<bean name="catalog"
class="com.bamboo.catW3.business.impl.Catalog">
<property name="successView">
<value>catalog</value>
</property>
<property name="catalogFacadeImpl" ref="catalogFacadeTarget"/>
</bean>
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass">
<value>org.springframework.web.servlet.view.JstlView</value>
</property>
<property name="prefix">
<value>/WEB-INF/jsp/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
现在这个工作正常，即使我的intellij IDE强调了catalogFacadeTarget引用，并且说我无法解析bean，这会很棒：如果有人知道如何让他变成并且，也许让我明白了：
<property name="catalogFacadeImpl" ref="*catalogFacadeTarget*"/>
这是工作的罚款对于那些没有复杂的人际关系简单的物体，比如我有一个不涉及任何表用户，我可以从这样做模型和查看方法在jstl控制器上：
List users = catalogFacadeImpl.getUserList();
没问题，我得到用户列表并打印它。但是，如果我尽量让这更复杂的物体上，具有与自身的关系的东西，就像对象类别：
List categories = catalogFacadeImpl.getCategoryList();
我得到exceptcion：
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.bamboo.catW3.domain.Category.categories, no session or session was closed
org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:488)
org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:431)
javax.servlet.http.HttpServlet.service(HttpServlet.java:690)
javax.servlet.http.HttpServlet.service(HttpServlet.java:803)
这通常是hbm和配置关系的问题，然而，这不可能是这样，因为从flex我称这种方法非常相同，并没有任何问题。所以我猜想我并没有像我一样分享这个bean。不，这也不会给我这个错误。
我现在非常困惑，任何有关在哪里寻找的建议都会深表感谢。非常感谢你，试图张贴HBM，以防万一它帮助，但是这个帖子很长。
考虑编辑这个问题。这些问题往往不会被阅读。 – 2010-11-14 22:57:49
未来会记住，得到这个答案，但不是完全阅读。谢谢 – Ernest 2010-11-15 13:41:12
