将EclipseLink 2.3.2与静态编织（Maven插件）一起用于OracleXE。JPA EclipseLink @ElementCollection未正确更新
我有以下实体
@Entity
@Table(name="LIST")
public class List {
...Id...
@ElementCollection(fetch = FetchType.EAGER)
@CollectionTable(name = "LIST_CONTENTS", joinColumns = @JoinColumn(name = "LIST_ID"))
@OrderColumn(name = "SEQ")
@Column(name = "CONTENT", length = 4000)
private java.util.List<String> contents;
}
，当我做更新内容如下：
// newContents is a String[]
em.getTransaction().begin();
List list = em.find(List.class,id);
list.setContents(new ArrayList<String>(Arrays.asList(newContents)));
em.getTransaction().commit();
我得到一个重复键错误 - 就像它没有删除旧数据

我不知道什么是错误的设置 - 我使用飞桥执行SQL/DDL我手写的。任何帮助表示赞赏。
你对集合表中的主键使用了什么？约束是说pk约束被违反了，所以检查你是否已经适当地设置了它 - 即你不只是使用LIST_ID作为pk，因为同一个列表中的两个元素将使用相同的LIST_ID。要么不为该表设置pk，要么使用像SEQ和LIST_ID这样独特的东西。如果不是这种情况，请尝试打开参数日志记录来查看正在使用的内容，方法是将“eclipselink.logging.parameters”属性设置为true。 – Chris 2012-02-24 15:34:19
是的 - PK是（list_id，seq） - 感谢您的日志提示。当我调试它时，我可以看到DirectCollectionMapping有7个更改 - 4个插入，然后3个删除（测试用例用4替换3个值） - 然后按顺序检查更改列表 - 首先执行插入操作。 – 2012-02-24 16:43:48
用H2试过我的测试并让EclipseLink生成模式。查看生成的模式，EclipseLink创建没有主键的表，以便插入然后删除，但删除list_id和内容上的匹配。如果我使用共享值更新列表，那么hella错误。 – 2012-02-24 17:38:10
