これは webx.xml フィルター設定です
そして私のカスタムフィルターで：
public class CustomSettingsFilter extends OncePerRequestFilter {
}
jpaセッションからエンティティをロードし、それを ThreadLocal に入れました。
しかし、春のmvcコントローラーで例外が発生した場合
"org.hibernate.PropertyValueException: not-null property references a null or transient value: net.shopxx.entity.Bom.member"
そして、私はこの例外をキャッチしませんでした。
次に、それは
<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>
新しい例外をスローします。

そして私は以下のことをします:
- 例外コードをコメントし、コントローラーで実行時例外をスローすると、セッションなしの例外は表示されませんでした。
- try catch でjpa例外をキャッチし、セッション例外も表示されなかった場合
助けてください。どうもありがとう
