查询订单:

所有的订单 不区分用户

基本的sql select* from orders where 1=1判断是否有state 若有则添加state 最后order by ordertime desc1.在left.jsp上添加5个连接/store/adminOrder?method=findAllByState 根据情况传入合适state就可以了2.在adminOrderServlet的findAllByState中

接受state

调用orderservice查询,list

将list放入request域中,请求转发list.jsp3.orderDao

先写一个基本的sql

判断state是否为空

最后添加order by

扩展:

查询订单详情

点击每一个订单后面的订单详情,将该订单的oid通过ajax传递到后台查询

步骤分析:

给按钮添加事件

/store/WebContent/admin/left.jsp

/store/src/com/louis/web/servlet/AdminOrderServlet.java

/*** 查询订单

*@throwsException*/

public String findAllByState(HttpServletRequest request, HttpServletResponse response) throwsException {//1.接受state

String state=request.getParameter("state");//2.调用service

OrderService os=(OrderService) BeanFactory.getBean("OrderService");

List list=os.findAllByState(state);//3.将list放入域中 请求转发

request.setAttribute("list", list);return "/admin/order/list.jsp";

}

/store/WebContent/WEB-INF/web.xml

AdminOrderServlet

AdminOrderServlet

com.louis.web.servlet.AdminOrderServlet

/adminOrder

/store/src/com/louis/service/impl/OrderServiceImpl.java

/***根据状态查询订单*/@Overridepublic List findAllByState(String state) throwsException {

OrderDao od=(OrderDao) BeanFactory.getBean("OrderDao");returnod.findAllByState(state);

}

/store/src/com/louis/dao/impl/OrderDaoImpl.java

@Overridepublic List findAllByState(String state) throwsException {

QueryRunner qr= newQueryRunner(DataSourceUtils.getDataSource());

String sql="select * from orders where 1=1 ";if(state!=null && state.trim().length()>0){

sql+= "and state = ? order by ordertime desc";return qr.query(sql,new BeanListHandler<>(Order.class),state);

}

sql+=" order by ordertime desc";return qr.query(sql, new BeanListHandler<>(Order.class));

}

/store/WebContent/admin/order/list.jsp

$.post("${pageContext.request.contextPath}/adminOrder",{"method":"getDetailByOid","oid":oid},function(data){

var s="

$(data).each(function(){

s+=("

});

s+="
