Question

有人可以在启动我的websphere服务器时帮助解决与hibernate相关的以下错误：

基本上，L_SUBLIST_DETAIL是带有主键的主表。这与其他2个表L_SUBLIST_CSI_BU_MAPPING和L_SUBLIST_RULESET_MAPPING有一对多的映射。问题似乎与L_SUBLIST_RULESET_MAPPING表并存，其中sublist_id和ruleset_id形成复合键，sublist_id是引用L_SUBLIST_RULESET_MAPPING表的sublist_id的外键。

************************** 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类如下。

LSublistRulesetMappingVO

@Entity

    return sublistId;
}

    this.sublistId = sublistId;
}

    return rulesetId;
}

public void setRulesetId(Long rulesetId) {

}

Answer 1

你不能在同一个类LSublistRulesetMappingVO中有两个主键@Id。

Answer 2

我更改了以下2个语句的顺序，服务器已启动。 any1可以解释什么是问题??????????????

旧：

@OneToMany（cascade = CascadeType.ALL，fetch = FetchType.EAGER，orphanRemoval = true） @JoinColumn（name =＆＃34; SUBLIST_ID＆＃34;，nullable = false）
private Set sublistCsiBUMappingVOSet;

@OneToMany（cascade = CascadeType.ALL，fetch = FetchType.EAGER，orphanRemoval = true） @JoinColumn（name =＆＃34; SUBLIST_ID＆＃34;，nullable = false）
private Set sublistRulesetMappingVOSet;

新：

@OneToMany（cascade = CascadeType.ALL，fetch = FetchType.EAGER，orphanRemoval = true） @JoinColumn（name =＆＃34; SUBLIST_ID＆＃34;，nullable = false）
private Set sublistRulesetMappingVOSet;

@OneToMany（cascade = CascadeType.ALL，fetch = FetchType.EAGER，orphanRemoval = true） @JoinColumn（name =＆＃34; SUBLIST_ID＆＃34;，nullable = false）
private Set sublistCsiBUMappingVOSet;

映射中的重复列为实体异常+ hibernate 3.5.6
