关于java中模糊查询的问题

我有一个实体bean ManualSign
public class ManualSign implements java.io.Serializable {
private Integer signId;
private UserInfo userInfo = new UserInfo();
private String signTime;
private String signDesc;
private Integer signTag;
}
其中userInfo类 中有属性:private Set departInfos = new HashSet(0);
private Integer departId;
而departInfo类中有属性:private String departName;
private BranchInfo branchInfo = new BranchInfo();
BranchInfo 类中又有属性:private Integer branchId;
private String branchName;

我在对ManualSign表写模糊查询的时候需要用departName和branchName进行分组

下面有一段我完成的部分模糊查询
//多项查询history页面
public List historySelect(final ManualSign man){
List list = null;
try {
list =getHibernateTemplate().executeFind(new HibernateCallback(){
public Object doInHibernate(Session session)
throws HibernateException, SQLException {
Criteria c = session.createCriteria(ManualSign.class);
