java - ORA-02289 : sequence does not exist when upgrade Hibernate 3 to hibernate 4

Question

当我将 hibernate 从 3.5 升级到 4.0.0.RC6 时，我遇到了与找不到序列相关的问题:

at org.hibernate.internal.SessionImpl.persist(SessionImpl.java:703) [hibernate-core-4.0.0.CR6.jar:4.0.0.CR6]
at org.hibernate.internal.SessionImpl.persist(SessionImpl.java:707) [hibernate-core-4.0.0.CR6.jar:4.0.0.CR6]

有人知道怎么解决吗？请让我知道。我正在使用 Oracle10gDialect 并使用我自己的 SequenceGenerator 覆盖 getNativeIdentifierGeneratorClass() 函数。它适用于 Hibernate 3.5，但在我升级到 Hibernate 4.0.0.RC6 时抛出异常

下面是我的 TableNameSequenceGenerator 类:

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);
    }
}

当我使用 hibernate 4 进行调试时，tableName 仅返回 REVINFO(它在 hibernate 3 中有效)

谢谢嘻嘻

Answer 1

我找到了答案。

对于所有类的公共(public)id生成器，我们应该使用

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

希望对和我有同样问题的人有所帮助。
