之前都没有报这个异常，修改一些代码后，后来在注册的时候报了这个异常
经检查后，发现PersonDAOImpl中，用system.out.println中有load了
注册的时候，不能有load，要用get，哪怕是在打印中也不能
然后我把打印注释了就正常了

问题代码如下：

	public Person queryByID(int id) {
		System.out.println("queryByID1*****" + (Person) this.getHibernateTemplate().get(Person.class, id));
		System.out.println("queryByID2*****" +  this.getHibernateTemplate().get(Person.class, id));
		System.out.println("queryByID3*****" +  this.getHibernateTemplate().load(Person.class, id));
		System.out.println("queryByID4*****" +  (Person) this.getHibernateTemplate().load(Person.class, id));
		return (Person) this.getHibernateTemplate().get(Person.class, id);	
	}

修改后为：

	public Person queryByID(int id) {
		System.out.println("queryByID1*****" + (Person) this.getHibernateTemplate().get(Person.class, id));
		System.out.println("queryByID2*****" +  this.getHibernateTemplate().get(Person.class, id));
//		System.out.println("queryByID3*****" +  this.getHibernateTemplate().load(Person.class, id));
//		System.out.println("queryByID4*****" +  (Person) this.getHibernateTemplate().load(Person.class, id));
		return (Person) this.getHibernateTemplate().get(Person.class, id);		
	}

这个再一次说明了，get和load的区别
