在Hsqldb/H2中进行单元测试的SequenceGenerator问题

Question

我已尝试使用Hsqldb和H2进行单元测试,但遇到了序列生成器的问题.字段声明如下所示.

@Id @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="keyword_seq")
@SequenceGenerator(name="keyword_seq",sequenceName="KEYWORD_ID_SEQ", allocationSize=1)
@Column(name="IM_KEYWORD_ID")
private Long keywordId;

当我尝试使用以下配置在Hsqldb中测试此表中的简单插入时,它会给出错误

<prop key="hibernate.connection.driver_class">org.hsqldb.jdbc.JDBCDriver</prop>
<prop key="hibernate.connection.url">jdbc:hsqldb:mem:testdb;sql.syntax_ora=true</prop>

错误:

   Caused by: java.sql.SQLSyntaxErrorException: user lacks privilege or object not found: KEYWORD_ID_SEQ.NEXTVAL
        at org.hsqldb.jdbc.Util.sqlException(Unknown Source)
        at org.hsqldb.jdbc.Util.sqlException(Unknown Source)

使用H2:

<prop key="hibernate.connection.driver_class">org.h2.Driver</prop>
<prop key="hibernate.connection.url">jdbc:h2:~/test</prop>

错误是:

Hibernate: select KEYWORD_ID_SEQ.nextval from dual
3085 [main] WARN org.hibernate.util.JDBCExceptionReporter  - SQL Error: 42001, SQLState: 42001
3088 [main] ERROR org.hibernate.util.JDBCExceptionReporter  - Syntax error in SQL statement "SELECT KEYWORD_ID_SEQ.NEXTVAL FROM[*] DUAL "; expected "identifier"; SQL statement:

任何想法,如何解决这个问题？

我认为方言设置错误.你能检查你的休眠配置吗？
