ORA-02289：將Hibernate 3升級到休眠4時序列不存在

Question

當我將hibernate從3.5升級到4.0.0時，我遇到了與序列無關的問題.RC6：

at org.hibernate.internal.SessionImpl.persist(SessionImpl.java:703) [hibernate-core-4.0.0.CR6.jar:4.0.0.CR6]

誰知道怎么修它？ 請告訴我。 我正在使用Oracle10gDialect並使用我自己的SequenceGenerator覆蓋getNativeIdentifierGeneratorClass（）函數。 當我升級到Hibernate 4.0.0.RC6時，它已經在Hibernate 3.5上工作但拋出了異常

下面是我的TableNameSequenceGenerator類：

public class TableNameSequenceGenerator extends SequenceGenerator {

    public void configure(Type type, Properties params, Dialect dialect) throws MappingException {
        if(params.getProperty(SEQUENCE) == null || params.getProperty(SEQUENCE).length() == 0) {
            String tableName = params.getProperty(PersistentIdentifierGenerator.TABLE);
            if(tableName != null) {
                String seqName = tableName + "_SEQ";
                params.setProperty(SEQUENCE, seqName);               
            }
        }
        super.configure(type, params, dialect);
    }
}

當我使用hibernate 4進行調試時，tableName只返回REVINFO（它在hibernate 3中工作）

謝謝Hiep

Answer 1

我找到了答案。

對於所有類的通用id生成器，我們應該使用

@Id
@GeneratedValue(generator="GENERATOR_COMMON")
@GenericGenerator(name="GENERATOR_COMMON",strategy="point.to.table.generator")

希望這能幫助像我這樣有同樣問題的人。

Answer 2

即使我遇到同樣的問題，請使用以下行

@GenericGenerator(name = "increment", strategy = "increment")
@GeneratedValue(generator = "increment")
