旅游线路详情
分析：
后台代码
RouteServlet：编写一个findOne方法
/**
* 根据id查询一个旅游线路的详细详细
* @param request
* @param response
* @throws ServletException
* @throws IOException
*/
public void findOne(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
//接收id
String rid = request.getParameter("rid");
//掉用service查询root对象
Route route = routeService.findOne(rid);
//转为json写回客户端
writeValue(route,response);
}
RouteDao接口：添加一个方法
/**
* 根据id查询
* @param rid
* @return
*/
public Route findOne(int rid);
RouteDaoImpl：实现
@Override
public Route findOne(int rid) {
String sql = "select * from tab_route where rid = ?";
return template.queryForObject(sql,new BeanPropertyRowMapper<Route>(Route.class),rid);
}
创建一个 RouteImgDao 接口
public interface RouteImgDao {
/**
* 根据route的id查询图片
* @param rid
* @return
*/
public List<RouteImg> findByRid(int rid);
}
在创建一个实现类实现这个接口
public class RouteImgDaoImpl implements RouteImgDao {
private JdbcTemplate template = new JdbcTemplate(JDBCUtils.getDataSource());
@Override
public List<RouteImg> findByRid(int rid) {
String sql = "select * from tab_route_img where rid = ?";
return template.query(sql,new BeanPropertyRowMapper<RouteImg>(RouteImg.class),rid);
}
}
在创建一个 SellerDao 接口
public interface SellerDao {
/**
* 根据id查询
* @param id
* @return
*/
public Seller findById(int id);
}
创建实现类进行实现
public class SellerDaoImpl implements SellerDao {
private JdbcTemplate template = new JdbcTemplate(JDBCUtils.getDataSource());
@Override
public Seller findById(int id) {
String sql = "select * from tab_seller where sid = ?";
return template.queryForObject(sql,new BeanPropertyRowMapper<Seller>(Seller.class),id);
}
}
RouteService：进行编写
/**
* 根据id查询
* @param rid
* @return
*/
public Route findOne(String rid);
RouteServiceImpl：实现
//在上面进行声明
private RouteImgDao routeImgDao = new RouteImgDaoImpl();
private SellerDao sellerDao = new SellerDaoImpl();
@Override
public Route findOne(String rid) {
//根据id去route表中查询route对象
Route route = routeDao.findOne(Integer.parseInt(rid));
//根据route的id查询图片集合信息
List<RouteImg> routeImgList = routeImgDao.findByRid(route.getRid());
//将集合设置到route对象
route.setRouteImgList(routeImgList);
//根据route的id查询卖家的信息
Seller seller = sellerDao.findById(route.getSid());
route.setSeller(seller);
return route;
}
有 json数据代表成功 http://localhost/travel/route/findOne?rid=1
前台代码
Route_detail.html中加载后
1.获取rid
2.发送ajax请求,获取route对象
3.解析对象的数据
route_list.html：中修改
添加rid
route_detail.html:(需要引入：js/getParameter.js)
颜色为的细节的修改
<script>标签中做了修改
