1.系统功能模块划分
该项目一共三个子系统
2.实体类设计与数据库表创建
一共十个类
Area类
public class Area {
//这里使用引用类型的原因是：我们希望可以存放null值，而不是默认值
private Integer areaId;
private String areaName;
private Integer priority;
private Date createTime;
private Date lastEditTime;
//get set ....
}public class HeadLine {
private Long lineId;
private String lineName;
private String lineLink;
private String lineImg;
private Integer priority;
//0,不可用 。 1，可用
private Integer enableStatus;
private Date createTime;
private Date lastEditTime;
}public class LocalAuth {
private Long localAuthId;
private String username;
private String password;
private Date createTime;
private Date lastEditTime;
private PersonInfo personInfo;
}public class PersonInfo {
private Long userId;
private String name;
private String profileImg;
private String email;
private String gender;
private Integer enableStatus;
//1.顾客 2.商家 3.超级管理员
private Integer userType;
private Date createTime;
private Date lastEditTime;
}public class Product {
private Long productId;
private String productName;
private String productDesc;
private String imgAddr;// 简略图
private String normalPrice;
private String promotionPrice;
private Integer priority;
private Date createTime;
private Date lastEditTime;
//0.下架 1.在前端展示系统展示
private Integer enableStatus;
private List<ProductImg> productImgList;
private ProductCategory productCategory;
private Shop shop;
}public class ProductCategory {
private Long productCategoryId;
private Long shopId;
private String productCategoryName;
private Integer priority;
private Date createTime;
}public class ProductImg {
private Long productImgId;
private String imgAddr;
private String imgDesc;
private Integer priority;
private Date createTime;
private Long productId;
}public class Shop {
private Long shopId;
private String shopName;
private String shopDesc;
private String shopAddr;
private String phone;
private String shopImg;
private Integer priority;
private Date createTime;
private Date lastEditTime;
//-1不可用 0审核中 1可用
private Integer enableStatus;
//超级管理员给店家的提醒
private String advice;
private Area area;
private PersonInfo owner;
private ShopCategory shopCategory;
}public class ShopCategory {
private Long shopCategoryId;
private String shopCategoryName;
private String shopCategoryDesc;
private String shopCategoryImg;
private Integer priority;
private Date createTime;
private Date lastEditTime;
private ShopCategory parent;
}public class WechatAuth {
private Long wechatAuthId;
private String openId;
private Date createTime;
private PersonInfo personInfo;
}然后在数据库中添加对应的表，我这里直接把所有的表的sql导出来了，直接复制就ok

</property>
</bean>
<!-- 4.扫描web相关的bean -->
<context:component-scan
base-package="com.yorisk.o2o.web" />
</beans>5.验证DAO
1.在dao层编写接口AreaDao.java
public interface AreaDao {
/**
* 列出区域列表
* @return areaList
*/
List<Area> queryArea();
}2.编写dao对应的mapper文件，AreaDao.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.yorisk.o2o.dao.AreaDao">
<select id="queryArea" resultType="com.yorisk.o2o.entity.Area">
SELECT area_id,area_name,priority,create_time,last_edit_time
FROM tb_area
ORDER BY priority DESC
</select>
</mapper>3.在src/test/java下，添加BaseTest.java
/**
* 配置spring和junit整合，junit启动时加载springIOC容器
* @author Administrator
*
*/
@RunWith(SpringJUnit4ClassRunner.class)
//告诉junit spring配置文件的位置
@ContextConfiguration({"classpath:spring/spring-dao.xml","classpath:spring/spring-service.xml"})
public class BaseTest {
}在src/test/java下，创建com.yorisk.o2o.dao包，在该包下创建AreaDaoTest
public class AreaDaoTest extends BaseTest{
@Autowired
private AreaDao areaDao;
@Test
public void testQueryArea() {
List<Area> areaList = areaDao.queryArea();
assertEquals(2,areaList.size());
}
}
验证成功。
6.验证Service层
1.在service层下创建AreaService.java接口，并在对应impl包下，创建对应实现类，AreaServiceImpl.java
public interface AreaService {
List<Area> getAreaList();
}
@Service
public class AreaServiceImpl implements AreaService{
@Autowired
private AreaDao areaDao;
@Override
public List<Area> getAreaList() {
return areaDao.queryArea();
}
}2.在src/test/java下的com.yorisk.o2o.service下创建AreaServiceTest.java
public class AreaServiceTest extends BaseTest{
@Autowired
private AreaService areaService;
@Test
public void testGetAreaList() {
List<Area> areaList = areaService.getAreaList();
assertEquals("西苑",areaList.get(0).getAreaName());
}
}
验证成功，lz当时做这个demo的时候还是出了很多错，提前给大家把坑说下
注意点1：service的实现类需要添加@Service注解
注意点2：BaseTest里，注解@ContextConfiguration需要添加classpath:spring/spring-service.xml
注意点3：spring-service.xml配置文件中，扫描service的包路径需要写对com.yorisk.o2o.service
7.验证Controller层
1.在web层添加superadmin包，在该包下添加AreaController.java
@Controller
@RequestMapping("/superadmin")
public class AreaController {
@Autowired
private AreaService areaService;
@RequestMapping(value="/listarea",method = RequestMethod.GET)
@ResponseBody
private Map<String,Object> listArea(){
Map<String,Object> modelMap = new HashMap<String,Object>();
List<Area> list = new ArrayList<Area>();
try{
list = areaService.getAreaList();
modelMap.put("rows", list);
modelMap.put("total", list.size());
}catch(Exception e) {
e.printStackTrace();
modelMap.put("success", false);
modelMap.put("errMsg", e.toString());
}
return modelMap;
}
}然后打开浏览器，输入http://localhost:8080/o2o/superadmin/listarea访问
这里推荐一款软件postman，是用来模拟浏览器发送请求，和接受响应的。
7.SSM框架重点知识
1.SpringMVC：DispatcherServlet
他用来拦截符合要求的外部请求，并把请求分发到不同的控制器中去，根据控制器处理后的结果，生成相应的响应发送到客户端，尽量了解源码和调用步骤。
2.Spring：IOC和AOP
ioc:控制反转，其实就是，我们以前获取对象，需要自己去创建，而现在有了Spring去帮我们创建，我们不需要了解创建的过程只管用就OK。举个通俗的例子就是，我们以前找女朋友需要自己去找，而现在有了Spring这个媒婆，我们只需要给媒婆说，我们喜欢的对象。然后媒婆给我们推送女朋友就ok了。ioc就是通过di，依赖注入实现的。
aop：面向切面编程，实现方式为动态代理
3.MyBatis:ORM
