Spring 当我的insert语句失败时，延迟加载没有会话异常

spring hibernate session spring-mvc

Spring 当我的insert语句失败时，延迟加载没有会话异常,spring,hibernate,session,spring-mvc,Spring,Hibernate,Session,Spring Mvc,已经从jpa会话加载了一个实体，我将它放在一个ThreadLocal中但是当在spring中mvc控制器出现异常时引起的 public class CustomSettingsFilter extends OncePerRequestFilter { } 我没有发现这个例外然后它就被处理了 "org.hibernate.PropertyValueException: not-null property references a null or transient value: net.s

已经从jpa会话加载了一个实体，我将它放在一个ThreadLocal中

但是当在spring中mvc控制器出现异常时引起的

public class CustomSettingsFilter extends OncePerRequestFilter {

}

我没有发现这个例外

然后它就被处理了

"org.hibernate.PropertyValueException: not-null property references a null or transient value: net.shopxx.entity.Bom.member"

common.i18n.entity.Currency_$$\uJavassist_6“我在ThreadLocal中持有的这个对象

异常日志：

 <bean id="exceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
    <property name="defaultErrorView" value="shop/common/error" />
    <property name="warnLogCategory">
        <value>
            org.springframework.web.servlet.handler.SimpleMappingExceptionResolver
        </value>
    </property>
</bean>

Template processing error: "get(currencyDescriptions) failed on instance of common.i18n.entity.Currency_$$_javassist_6"

Caused by: org.hibernate.LazyInitializationException: could not initialize proxy - no Session

我做了以下几件事：

注释异常代码。并在控制器中引发运行时异常，没有出现任何会话异常

如果我通过try-catch捕获jpa异常，并且没有出现任何会话异常

请帮助我。谢谢大家

你能发布你的映射和一些代码吗？嗨，我在我的实体上使用了jpa注释。这个由not null属性引起的异常引用了一个null或瞬态值，因为我没有给这个属性赋值，然后导致了这个异常，现在，我关心的是，为什么？1.会话已关闭？这个异常可能有不同的类型原因，一些提示为什么？会话关闭了？正如我在文章中所描述的，当我故意注释被新的RuntimeException替换的perisit代码段时，目标实体延迟加载是正常的，或者我在perisit代码段周围进行了一次尝试捕获，这也是正常的，所以它只在我有任何操作时出现，只需处理spring mvc exceptionResolver，不正常现在！太混乱了。@Benoit Wickramarachi，在我的例子中，与您给定的链接有一些不同，我从来没有手动关闭会话，我希望应用程序异常可以由默认的spring异常解析程序在没有捕获任何异常的情况下通过会话关闭来捕获。如果只是从这个问题开始，我只给它一个值。
