hibernate 多对一 ，多对多 hql 查询语句

[qq_18997393]

三个层级，公司，部门，员工
点击公司可以查到所有员工实体，点击部门可以查到当前部门和下属部门的说有员工实体，
hql怎么写啊？？？？？
相关代码如下：
CompanyInfo

@Entity
@Table(name="COMPANY_INFO")
public class CompanyInfo extends BaseEntity {
	
	@Column(name="companyCode")
	private String companyCode;
	
	@Column(name="companyName")
	private String companyName;
	
	@Column(name="eDesc")
	private String eDesc;

	public String getCompanyCode() {
		return companyCode;
	}

	public void setCompanyCode(String companyCode) {
		this.companyCode = companyCode;
	}

	public String getCompanyName() {
		return companyName;
	}

	public void setCompanyName(String companyName) {
		this.companyName = companyName;
	}

	public String geteDesc() {
		return eDesc;
	}

	public void seteDesc(String eDesc) {
		this.eDesc = eDesc;
	}
	

Organization

@Entity
@Table(name="WMS_ORG")
public class Organization  extends BaseEntity{
	
	@Column(name="orgName")

		}
		return false;
	}
	
	@Override
	public int hashCode() {
		return ("org_" + getId()).hashCode();
	}
}

有没有大神知道怎么写hql的啊 ，

[mtian2020]

查询所有员工应该是这样： Query query = session.createQuery("from WMSUser where 1=1"); List<WMSUser > list = query.list();
