ORA-02289:将Hibernate 3升级到休眠4时序列不存在

Question

当我将hibernate从3.5升级到4.0.0时,我遇到了与序列无关的问题.RC6:

谁知道怎么修它？请告诉我.我正在使用Oracle10gDialect并使用我自己的SequenceGenerator覆盖getNativeIdentifierGeneratorClass()函数.当我升级到Hibernate 4.0.0.RC6时,它已经在Hibernate 3.5上工作但抛出了异常

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只返回REVINFO(它在hibernate 3中工作)

谢谢Hiep

Answer 1

我找到了答案。

对于所有类的通用 id 生成器，我们应该使用

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

希望这可以帮助像我一样遇到同样问题的人。
