三后端代码实现

RouteServlet
RouteService
RouteDao、RouteImgDao、SellerDao

RouteServlet代码实现

/**
     * 根据id查询一个旅游线路的详细信息
     * @param request
     * @param response
     * @throws ServletException
     * @throws IOException
     */
    public void findOne(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        //1.接收id
        String rid = request.getParameter("rid");
        //2.调用service查询route对象
        Route route = routeService.findOne(rid);
        //3.转为json写回客户端
        writeValue(route,response);
    }

RouteService代码实现

 @Override
    public Route findOne(String rid) {
        //1.根据id去route表中查询route对象
        Route route = routeDao.findOne(Integer.parseInt(rid));
        
        //2.根据route的id 查询图片集合信息
        List<RouteImg> routeImgList = routeImgDao.findByRid(route.getRid());
        //2.2将集合设置到route对象
        route.setRouteImgList(routeImgList);
        //3.根据route的sid（商家id）查询商家对象
        Seller seller = sellerDao.findById(route.getSid());
        route.setSeller(seller);
        
        return route;
    }

RouteDaoImpl代码实现

@Override
    public Route findOne(int rid) {
        String sql = "select * from tab_route where rid = ?";
        return template.queryForObject(sql,new BeanPropertyRowMapper<Route>(Route.class),rid);
    }

RouteImgDaoImpl代码实现

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);
    }
}

SellerDaoImpl代码实现

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);
    }
}

四前端代码实现

Route_detail.html中加载后

获取rid
发送ajax请求，获取route对象
解析对象数据
