實體例外+休眠3.5.6映射中的重復列

Question

在啟動我的Websphere服務器時，是否可以幫助解決以下與休眠有關的錯誤：

基本上，L_SUBLIST_DETAIL是我的帶有主鍵的主表。 它與其他2個表L_SUBLIST_CSI_BU_MAPPING和L_SUBLIST_RULESET_MAPPING具有一對多映射。 問題似乎在於L_SUBLIST_RULESET_MAPPING表，其中sublist_id和ruleset_id構成一個組合鍵，而sublist_id是一個外鍵，它引用了L_SUBLIST_RULESET_MAPPING表的sublist_id。

************************** Error ******************

Invocation of init method failed; nested exception is org.hibernate.MappingException: Repeated column in mapping for entity: com.myProj.appName.ruleset.vo.LSublistRulesetMappingVO column: SUBLIST_ID (should be mapped with insert="false" update="false")

涉及的Java類如下。

LSublist規則集映射VO

@Entity

Answer 1

您不能在同一類LSublistRulesetMappingVO中擁有兩個主鍵@Id。

Answer 2

我更改了以下2條語句的順序，並且服務器已啟動。 any1可以解釋出什么問題嗎？

舊：

@OneToMany（cascade = CascadeType.ALL，fetch = FetchType.EAGER，orphanRemoval = true）@JoinColumn（name =“ SUBLIST_ID”，nullable = false）
私人Set sublistCsiBUMappingVOSet;

@OneToMany（cascade = CascadeType.ALL，fetch = FetchType.EAGER，orphanRemoval = true）@JoinColumn（name =“ SUBLIST_ID”，nullable = false）
私人Set sublistRulesetMappingVOSet;

新：

@OneToMany（cascade = CascadeType.ALL，fetch = FetchType.EAGER，orphanRemoval = true）@JoinColumn（name =“ SUBLIST_ID”，nullable = false）
私人Set sublistRulesetMappingVOSet;

@OneToMany（cascade = CascadeType.ALL，fetch = FetchType.EAGER，orphanRemoval = true）@JoinColumn（name =“ SUBLIST_ID”，nullable = false）
私人Set sublistCsiBUMappingVOSet;
