1. mybatis依赖配置

// 继承Mapper，MySqlMapper  其他业务Mapper继续“MyMapper”，可直接操作增删改查方法
public interface MyMapper<T> extends Mapper<T>,MySqlMapper<T>{
}

业务代码

1.首页代码-controller层

@RequestMapping(value = {"/","https://segmentfault.com/a/1190000038996214/index","main",""})
public ModelAndView index(ModelAndView mav,HttpServletRequest request){
Person person=(Person)request.getSession().getAttribute("user");
List<Product> productList= productService.getProductList();
if(null!=person){
Trx trx=new Trx();
if(person.getUserType().equals(0)){    //买家
trx.setPersonId(person.getId());
}
List<Product> productList2=new ArrayList<>();
List<Trx> trxList=trxService.getTrxList();    //根据当前登录id查询是否购买
if(null!=trxList&&trxList.size()>0){
for(Product p:productList){
for(Trx t:trxList){
if(t.getProductId().equals(p.getId())){
p.setIsSell(1);
}
}
if(person.getUserType()==1){    //卖家角色 查询当前商品买过多少
Trx t1=new Trx();
t1.setProductId(p.getId());
List<Trx> list=trxService.getTrxByParm(t1);
p.setBuyNum(list.size());
}
productList2.add(p);
}
mav.addObject("productList",productList2);    //过滤后的商品列表
}
mav.addObject("productList",productList);
}else{
mav.addObject("productList",productList);    //商品列表
}
mav.setViewName("https://segmentfault.com/a/1190000038996214/index");
return mav;
}

1.1 首页代码-service层

@Service
public class ProductServiceImpl implements ProductService {
@Autowired
ProductMapper productMapper;
//商品列表
public List<Product> getProductList(){
return productMapper.selectAll();
}
}

1.2 首页代码-dao层-Mapper

//继承MyMapper类，获取超类的增删改查方法
public interface ProductMapper extends MyMapper<Product> {
}

1.3 首页代码-jsp

项目总结

项目做得比较简易，页面偏向简洁，不过有一个完整的商城主流程，此外还编写了freemaker版本的购物商城代码，后续上传源码。
