note The full stack trace of the root cause is available in the Apache Tomcat/6.0.13 logs.点“订单查询”就出现这样的错误。

Answer 1

你把出错的severlet代码贴出来嘛，500代码错误

Answer 2

while calling setter of emp.shop.model.Orders.orderItem检查setter方法格式是否正确。

Answer 3

IllegalArgumentException 非法参数异常emp.shop.dao.OrderDaoImpl.queryOrderByOrderId(OrderDaoImpl.java:44)
你看是不是传递了非法的参数
emp.shop.model.Orders.orderItem

Answer 4

package emp.shop.dao;import java.util.List;import org.springframework.orm.hibernate3.support.HibernateDaoSupport;import emp.shop.idao.IOrderDao;
import emp.shop.model.Orders;public class OrderDaoImpl extends HibernateDaoSupport implements IOrderDao { public void addOrder(Orders orders) { this.getHibernateTemplate().save(orders);
} public void deleteOrder(int order_id) { } public void modifyOrder(int order_id) { } public Orders queryOrderByUserId(int user_id) {

List orderList = this.getHibernateTemplate().find("from Orders where user.user_id='"+user_id+"'");
Orders orders = null;
if(orderList.size() == 1){
orders = (Orders) orderList.get(0);
}
return orders;
}

public List<Orders> queryOrderByList(int user_id) {

List<Orders> orderList = this.getHibernateTemplate().find("from Orders where user.user_id="+user_id);

return orderList;
} public Orders queryOrderByOrderId(int order_id) {

Orders orders = (Orders) this.getHibernateTemplate().find("from Orders where order_id =" +order_id);

return orders;
}}

Answer 5

你的order类里的属性类型和数据库此表字段类型不一致造成的吧

Answer 6

public Orders queryOrderByOrderId(int order_id) {

System.out.println(order_id+"===================");
List<Orders> orderList =this.getHibernateTemplate().find("from Orders where order_id =" +order_id);
System.out.println(orderList.size()+"===================");
return orderList.get(0);
