Question

这怎么可能发生。

不是liquibase应该为自己创建这个表...

这是为单元测试而创建的内存数据库。

public void setUp(String contexts) {
    try {
        ResourceAccessor resourceAccessor = new FileSystemResourceAccessor();
        Class.forName("org.hsqldb.jdbcDriver");
        holdingConnection = getConnectionImpl();
        HsqlConnection hsconn = new HsqlConnection(holdingConnection);
        liquibase = new Liquibase(CHANGE_LOG, resourceAccessor, hsconn);
        liquibase.dropAll();
        liquibase.update(contexts);
        hsconn.close();
    } catch (Exception ex) {
        LOG.error("Error during database initialization", ex);
        throw new RuntimeException("Error during database initialization", ex);
    }
}
private Connection getConnectionImpl() throws SQLException {
    return DriverManager.getConnection(CONNECTION_STRING, USER_NAME, PASSWORD);
}

与hsqldb示例相同

Answer 1

hsqldb上的错误通常表示该表不存在。如果在检查后删除databasechangelog表，则“存在databasechangelog表存在”缓存机制可能会变得不正确。

在即将发布的liquibase 3.3版本中有一个修复程序，但是现在如果你在清除数据库的地方添加ChangeLogHistoryServiceFactory.getInstance().reset()它应该解决问题。

Answer 2

我相信当您的连接关闭或无效时，可能会发生此错误。

将Hsqldb-2.3.2与连接池（如dbcp）和validationQuery一起使用时，我遇到了同样的错误。一旦validationQuery使连接失效，就会在下一次数据库访问时抛出错误。

由于您在测试中，这不是您的问题，但您可以调试连接，看看它是否在出错时打开。

org.hsqldb.HsqlException：user缺少未找到的权限或对象：DATABASECHANGELOGLOCK
