这是 webx.xml 过滤器设置
在我的自定义过滤器中：
public class CustomSettingsFilter extends OncePerRequestFilter {
}
已经从 jpa 会话加载了一个实体，我把它放在了 ThreadLocal 中。
但是在spring mvc控制器出现异常的时候是由
"org.hibernate.PropertyValueException: not-null property references a null or transient value: net.shopxx.entity.Bom.member"
我没有发现这个异常。
然后它处理
<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>
抛出一个新异常：
Template processing error: "get(currencyDescriptions) failed on instance of common.i18n.entity.Currency_$$_javassist_6"
Caused by: org.hibernate.LazyInitializationException: could not initialize proxy - no Session
common.i18n.entity.Currency_$$_javassist_6" 我在 ThreadLocal 中持有的这个对象
异常日志：

我在下面做一些事情：
- 注释异常代码。在控制器中抛出运行时异常，没有出现无会话异常；
- 如果我通过 try catch 捕获 jpa 异常，并且也没有出现没有会话异常
请帮助我。谢谢大家
