数据库多对多, fetche查询解决思路

数据库多对多, fetche查询
我的订单Orders与Goods的映射关系，多对多的，设置了fetch 为eager，

	@ManyToMany(fetch=FetchType.EAGER)
	@JoinTable(name = "order_goods", joinColumns = { @JoinColumn(name = "order_id") }, inverseJoinColumns = { @JoinColumn(name = "goods_id") })
	private Set<Goods> goods = new HashSet<Goods>();

Junit Test:我在取订单信息时，也会把所关联的商品信息取出来，

String hql = "from Orders where id=1";
		Query query = (Query) s.createQuery(hql);

		List<Orders> list = query.list();
		
		System.out.println(list.size());

下面是后台发的sql语句，
