hibernate自定义sql关联查询后，结果集如何处理
public SimplePage<WorkFlowEventDto> listPage(WorkFlowEventDto condition, int start, int limit) {
StringBuilder selectColumnSql = new StringBuilder("SELECT a.`id` as id,g.name as resourceType,b.name as instanceName,pin.`serial_num` AS instanceNumber," +
"h.`op_name` as operation,a.status as status,a.`create_time` as createdTime,c.`vm_name` as vmName" +
",d.`vdisk_name` as vdiskName,e.`file_sys_name` as fsName");
StringBuilder selectCountSql = new StringBuilder("select count(a.id)");
StringBuilder sql = new StringBuilder(
" FROM work_flow_event a LEFT JOIN resource_instance b ON a.`resourece_instance_id`=b.`id`" +
" LEFT JOIN product_instance pin ON pin.`id`=b.`product_instance_id`" +

if (condition != null) {
if (StringUtils.isNotBlank(condition.getInstanceName())) {
sql.append(" AND b.`name` LIKE ?");
params.add("%"+condition.getInstanceName()+"%");
}
if (StringUtils.isNotBlank(condition.getInstanceNumber())) {
sql.append(" AND pin.`serial_num` LIKE ?");

SQLQuery q = this.getSession().createSQLQuery(selectColumnSql.toString());

for (int i = 0; i < params.size(); i++) {
q.setParameter(i, params.get(i));
qc.setParameter(i, params.get(i));
}
q.addScalar("id", Hibernate.INTEGER);
q.addScalar("resourceType", Hibernate.STRING);
q.addScalar("instanceName", Hibernate.STRING);
q.addScalar("instanceNumber", Hibernate.STRING);
q.addScalar("operation", Hibernate.STRING);
q.addScalar("status", Hibernate.INTEGER);
q.addScalar("createdTime", Hibernate.TIMESTAMP);
q.addScalar("vmName", Hibernate.STRING);

q.setResultTransformer(Transformers.aliasToBean(WorkFlowEventDto.class));
List<WorkFlowEventDto> data = q.setMaxResults(limit).setFirstResult(start).list();
int totalCount = Integer.valueOf(qc.uniqueResult().toString());
return new SimplePage<WorkFlowEventDto>(data, totalCount);这是一个按条件分页查询，主要就是用hibernate查询出对象
WorkFlowEventDto不是一个hibernate实体，重要的不是上边那堆，注意看setResultTransformer(Transformers.aliasToBean(WorkFlowEventDto.class))
