标签：

一、整理所需要的架包

　　此次整合只有Mybatis 和Spring mvc的架包其他内容暂不讨论

　　技术分享

二、使用 mybatis 自动生成工具生成 interface（dao层文件） mapper（SQL文件） model（实体类） service（逻辑）文件

编写service 的实现类

三、编写 Spring 配置文件

　　Spring配置

四、编写控制器（controller）与测试类

 1 package sy.controller;
 2 
 3 import java.util.List;
 4 
 5 import javax.servlet.http.HttpServletRequest;
 6 
 7 import org.springframework.beans.factory.annotation.Autowired;
 8 import org.springframework.stereotype.Controller;
 9 import org.springframework.web.bind.annotation.RequestMapping;
10 import org.springframework.web.bind.annotation.RequestMethod;
11 
12 import sy.model.Goods;
13 import sy.service.GoodsService;
14 import sy.service.OrdersService;
15 import sy.service.UserService;
16 
17 @Controller
18 @RequestMapping("/index")
19 public class Index {
20 
21     private UserService userService;
22     private OrdersService ordersService; // 订单
23     private GoodsService goodsService; // 商品
24     private List<Goods> list; // 商品集合
25 
26     @RequestMapping("/show")
27     public String show(HttpServletRequest request) {
28         list = goodsService.selectAll();
29         Goods goods = goodsService.selectByPrimaryKey(1);
30         request.setAttribute("list", list);
31         request.setAttribute("goods", goods);
32         System.out.println(goods.getGname());
33         return "WEB-INF/user/show";
34     }
35     @RequestMapping(method = RequestMethod.GET ,value = "/show")
36     
37     
38     
39     
40     
41     
42     public UserService getUserService() {
43         return userService;
44     }
45 
46     @Autowired
47     public void setUserService(UserService userService) {
48         this.userService = userService;
49     }
50 
51     public OrdersService getOrdersService() {
52         return ordersService;
53     }
54 
55     @Autowired
56     public void setOrdersService(OrdersService ordersService) {
57         this.ordersService = ordersService;
58     }
59 
60     public GoodsService getGoodsService() {
61         return goodsService;
62     }
63 
64     @Autowired
65     public void setGoodsService(GoodsService goodsService) {
66         this.goodsService = goodsService;
67     }
68 
69 }

　　编写测试类

 1 package sy.test;
 2 
 3 import java.util.List;
 4 
 5 import org.junit.runner.RunWith;
 6 import org.springframework.beans.factory.annotation.Autowired;
 7 import org.springframework.test.context.ContextConfiguration;
 8 import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
 9 
10 import sy.model.Goods;
11 import sy.service.GoodsService;
12 import sy.service.UserService;
13 
14 
15 @RunWith(SpringJUnit4ClassRunner.class)
16 @ContextConfiguration(locations={"classpath:spring.xml","classpath:spring-mybatis.xml"})//加载配置文件
17 public class Test {
18 
19     private UserService userService;
20     private GoodsService goodsService;
21     
22     @org.junit.Test
23     public void select(){
24     //    Users users=userService.selectUserByid(1);
25     //    System.out.println(users.getUname());
26     //    Goods goods =goodsService.selectByPrimaryKey(1);
27     //    System.out.println(goods.getGname());
28         List list =goodsService.selectAll();
29         Goods goods=    (Goods) list.get(0);
30         System.out.println(goods.getGname());
31     }
32     
33     
34     
35     
36     
37     
38     
39     
40     
41     
42     
43     public GoodsService getGoodsService() {
44         return goodsService;
45     }
46     @Autowired
47     public void setGoodsService(GoodsService goodsService) {
48         this.goodsService = goodsService;
49     }
50     public UserService getUserService() {
51         
52         return userService;
53     }
54     @Autowired
55     public void setUserService(UserService userService) {
56         this.userService = userService;
57     }
58     
59 
60     
61     
62     
63 }
