Hsqldb/H2 中单元测试的 SequenceGenerator 问题
我尝试过使用 Hsqldb 和 H2 进行单元测试,但面临序列生成器的问题。字段声明看起来像这样。
@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>
Error :
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)
With H2:
<prop key="hibernate.connection.driver_class">org.h2.Driver</prop>
<prop key="hibernate.connection.url">jdbc:h2:~/test</prop>
Error is :
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:
知道吗,如何解决这个问题?
I have tried using both Hsqldb and H2 for unit testing but facing problem with sequence generators. Field declaration looks like this.
@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;
When I try to test simple insert in this table in Hsqldb with following configuration, it gives error
<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>

With H2:

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

Any idea, how to solve this?

我认为方言设置错误。你能检查一下你的休眠配置吗?
I think the dialect is set wrongly. Can you check your hibernate configuration.
