我对开源estatio(基于apache isis构建(有一个问题
我首先在 DDL 文件中导出了数据库架构。之后，我将DDL文件导入PostgresSQL 9.5。可以启动应用程序。并且一些夹具可以执行。我在"Estatio 演示夹具"中遇到的问题。该应用程序似乎导入很少的夹具，直到应用程序尝试导入org.estatio.fixture.financial.BankAccountForAcmeNl。 发生以下异常：

CommunicationChanel的id在DB中描述如下："id int4 not null default nextval('"IncodeCommunications"(。CommunicationChannel_id_seq"'：：regclass(">
将自动为每个插入语句创建此表的 Id。在这种情况下，这不是插入语句，而是没有引用 ID 的查找语句。我的意思是它会在CommunicationChanelOwnerLink中查找，如果有任何ID为空的行。
public void setObject(PreparedStatement ps, int param, Object value)
{
try
{
if (value == null)
{
if (column != null && column.isDefaultable() && column.getDefaultValue() != null && !StringUtils.isWhitespace(column.getDefaultValue().toString()))
{
ps.setLong(param, Long.valueOf(column.getDefaultValue().toString().trim()).longValue());
}
else
BigIntRDBMSMapping的这个块代码说，如果值为空(正是在这种情况下(，那么它将尝试解析之前由datanucleus初始化的默认值。在这种情况下，默认值 ="nextvalIncodeCommunications.CommunicationChannel_id_seq：：regclass"。此值不能转换为长整型值。
知道这里到底发生了什么吗？ 谢谢。
用例：请参阅我的评论 Apache Isis：Java 类型映射失败
根本原因：请参阅我的评论Apache Isis：Java类型映射失败
解决方案：不存在官方解决方案。我和datanucleus团队的Andy Jefferson谈过。但没有有用的答案。最后，我已经自己修补了库并等待适当的修复
