当我尝试使用 DaoImpl 类中的 HIbernate 执行存储过程时,出现以下异常。我不确定出了什么问题..我尝试了所有方法来解决它,但没有解决问题。谁能帮助我,找出代码或映射文件有什么问题。我尝试修复的越多,我得到的异常就越多。我正在连接到 Oracle 9i DB。从真正的 2 周开始,我一直在努力解决这个问题。任何人都可以帮我解决这个问题。
映射文件:
<hibernate-mapping>
<sql-query name="proc_drsrr_sel_ValDDSummaryBal">
<!--CALL proc_drsrr_sel_ValDDSummaryBal(:param1)]]>-->
{ call DEFAULT_SCHEMA.proc_name(?,:param1) }
主类:
public static void main(String[] args) {
String procName = "proc_name";// args[0];
String params = "param1:500089" ;
DAO 实现:
@SuppressWarnings("unchecked")
public void callProc(String procName, Map paramMap) throws SQLException {
Session session = null;
Transaction tx = null;
try {
session = HibernateUtils.getSessionFactory().getCurrentSession();
tx = session.beginTransaction();
String dbURL = session.connection().getMetaData().getURL().toString();
System.out.println("Conenction DB URL "+ dbURL );
tx.setTimeout(5);
String[] keys = new String[paramMap.size()];
keys = (String[]) paramMap.keySet().toArray(keys);
Query query = session.getNamedQuery(procName)
.setParameter("param1", "5501010");
}
List result = query.list();
System.out.println(query.getQueryString());
for (int i = 0; i < result.size(); i++) {
// logging the information.
log.info(i);
}
tx.commit();
} catch (RuntimeException exception) {
exception.printStackTrace();
try {
tx.rollback();
} catch (RuntimeException rbe) {
log.error("Couldn’t roll back transaction", rbe);
rbe.printStackTrace();
}
throw exception;
} finally{
if(session !=null){
session.flush();
session.close();
}
