Answer 2

for(Manager_medicine managerMedicine2 : medicineService.find(managerMedicine,findtype))
{
System.out.println("进入这一部："+managerMedicine2.getM_name()+managerMedicine2.getM_factory()+managerMedicine2.getM_date()+managerMedicine2.getM_price()+managerMedicine2.getM_type());
session.put("m_name", managerMedicine2.getM_name());
session.put("m_factory", managerMedicine2.getM_factory());
session.put("m_price", managerMedicine2.getM_price());
session.put("m_date", managerMedicine2.getM_date());
session.put("m_prange", managerMedicine2.getM_prange());
session.put("m_type", managerMedicine2.getM_type());
session.put("length0", length0);
}
这是一个for循环，但是我查询的过程中每一次只查询到一次for循环的值
可是我想查询到所有for循环的值

Answer 3

medicineService.find(managerMedicine,findtype)
先用个对象进行接收保存，再遍历这个对象呢，不然你每次循环都要去调用这个
