spring+hibernate做查询时多次调用提示地址被占用的错误是什么原因?

我采用了spring+hibernate进行数据查询时,如果让连接多次查询(几千次),就报以下错误
org.springframework.jdbc.UncategorizedSQLException: (Hibernate operation): encountered SQLException [Network error IOException: Address already in use: connect]; nested exception is java.sql.SQLException: Network error IOException: Address already in use: connect

... 37 more
我用测试程序连接调用的方法代码是
public int channelResInfoNums(String channelid) {
int totalCount = 0;
Query query = null;
String sql = null;
Session s = this.getSession();
try {
sql = "SELECT count(a.id) FROM UserInfo AS a WHERE a.code='101'";
query = getHibernateTemplate().createQuery(s, sql);
totalCount = ( (Integer) query.iterate().next()).intValue();

}
catch (Exception ex) {
totalCount=0;
}
finally {
closeSessionIfNecessary(s);
}
return totalCount;
}
