我需要将jTable中的所有行插入到MS SQL server DB中。我正在使用hibernate。这是我尝试过的代码。如果我正在尝试打印spname，vreq，vcol，cnname和sta，则会打印，但我无法将这些值加载到DB因为循环只工作一次，所以它只插入一次。
我需要将spname，vreq，vcol，cnname和sta的多个值加载到同一个Labitemcode中。如果有人在这个问题上帮助我，将会很有帮助。
try {
queries();
Login.session = Login.sessionfactory.openSession();
Login.session.beginTransaction();
for (int row = 0; row < jTable3.getRowCount(); row++) {
TstSpecimenPojo tsp = new TstSpecimenPojo();
String spname = (String) jTable3.getModel().getValueAt(row, 0);
String vreq = (String) jTable3.getModel().getValueAt(row, 1);
String vcol = (String) jTable3.getModel().getValueAt(row, 2);
String cnname = (String) jTable3.getModel().getValueAt(row, 3);
int sta = (int) jTable3.getModel().getValueAt(row, 4);
tsp.setLabitemcode(Labitemcode);
tsp.setSpecimenid(spname);
tsp.setVolreq(vreq);
tsp.setVolcol(vcol);
tsp.setContid(cnname);
tsp.setTststatus(sta);
Login.session.save(tsp);
}
Login.session.getTransaction().commit();
} catch (HibernateException e) {
System.out.println(e.getMessage());
}
printStackTrace（）的结果

标识种子值的整数溢出可能会导致此问题。
此案例有三种快速解决方案：
1 - ）您可以使用
更改您的表格ALTER TABLE table_name
ALTER COLUMN id_column_name bigint
2-）如果Identity Seed很大但某些id值范围不存在你可以重新种子为1或任何其他空种子范围：
DBCC CHECKIDENT ('table_name', RESEED, 1)
3-）在management Studio中，右键单击该表，然后按照脚本表as-＆gt; create to-＆gt; New Query Editor Window
更改＆＃34; int＆＃34;输入＆＃34; bigint＆＃34;为您的ID列。在窗口中保留此创建新表命令。然后重命名您的表，最后执行我们刚刚保留的create table命令。然后您可以将数据从旧的（重命名的）表移动到新表中（我建议使用SSIS包，导入数据功能以移动大数据）
