我是一个春天新手尝试我的第一个应用程序。我的hibernate在呈现视图之前关闭，并且在延迟加载属性（预期行为）方面存在问题。我已将OpenSessionInViewFilter添加到我的web.xml中并导致以下内容：
java.lang.IllegalStateException: No WebApplicationContext found: no ContextLoaderListener registered?
事先用我所拥有的默认servlet上下文配置工作正常（有人可以告诉我为什么吗？）。所以我添加了以下内容：
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/springapp-servlet.xml
</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
新的错误消失了......但仍然从hibernate获得了无会话异常
org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.test.model.Store.categories, could not initialize proxy - no Session
我在我的一个控制器中放了一条调试消息，它似乎被初始化了3次。也许我有多个hibernate会话工厂bean的实例？我的控制器方法被标记为@Transactional，一切正常，直到我试图打开会话以使视图可用的惰性字段。
我的完整web.xml（添加了新的上下文，在我添加了hibernate过滤器之前没有它正常工作）：

我的控制器初始化两次，根ApplicationContext和FrameworkServlet使用相同的配置。我已经初始化了两个上下文。我已经为名为springapp.xml的根上下文创建了一个配置，并在那里移动了我所有的中间层配置，并在springapp-servlet.xml中保留了我的Web层配置
我的web.xml现在看起来像这样，一切正常：
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/springapp.xml
</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<filter>
<filter-name>hibernateFilter</filter-name>
<filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
<init-param>
<param-name>sessionFactoryBeanName</param-name>
<param-value>sessionFactory</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>hibernateFilter</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>

</filter-mapping>

为了解决我的问题，它只是错过了这一行
在应用程序上下文文件中。
未考虑方法上的@Transactional注释。
希望它会帮助某人
