Hibernate 报错，could not initialize proxy ?报错

我使用的是hibernate 4.3，实体用的是注解进行配置：

我碰到很奇怪的问题，我没有让hibernate进行lazy的操作，并且不希望有这类的操作出现。我在网络上翻了一下，这类报错应该是懒加载造成的：session关闭了，配置了lazy的属性无法拿到其内容，实体中的代理类无法查询数据报错。可是我这里没有配置任何的懒加载操作啊，为什么还有这种报错？是不是hibernate给我的还是一个代理类呢？如何让他给我本身的实体，而不是代理类呢？这报错让我无法进行实体序列化成为json了。

实体类

@Entity
@Lazy(false)
public class Organization {
	@Id
	@Column(length=32)
	@GeneratedValue(generator="id")
	@GenericGenerator(name="id",strategy="uuid")
	private String id;
	//组织名称
	@Column(nullable=false)
	private String name;
	//顺序
	private Double showorder;
	//上级组织
	@ManyToOne
	@JoinColumn(name="supOrg")
	private Organization supOrg;
	//组织类型
	@Column(length=32)
	private String type;
	//下级组织
	@OneToMany(mappedBy="supOrg")
	@Lazy(false)
	private Set<Organization> organizations=new HashSet<Organization>();
	//下级人员
	@OneToMany(mappedBy="org")
	private Set<UserInfo> userInfos=new HashSet<UserInfo>();
	
	//包含岗位
	@OneToMany(mappedBy="org")
	private Set<Station> stations=new HashSet<Station>();

..省略get,set

测试代码：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/SpringContext.xml")
public class TestOrganization {
	@Resource
	private OrganizationService organiationService;
	@Resource
	private SessionUtil sessionUtil;
	/*@Resource
	private SessionUtil sessionUtil;*/
	@Test
	public void insertUserInfo(){
		try {
			Session s=sessionUtil.getSession();
			Query q=s.createQuery("from Organization where id=:id").setString("id", "402893814fbb4e88014fbb4e93680000");
			Organization org=(Organization)q.uniqueResult();
			//Hibernate.initialize(org.getOrganizations());
			s.close();
			System.out.println(org.getOrganizations()==null);
			
			System.out.println(org.getOrganizations().size());
			
			
			
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
	}
}
