2. 实现查询订单操作

2.1 编写实体类

/**
 * 会员实体类
 */
public class Member implements Serializable {
    private Integer id; // 主键
    private String name; // 会员姓名
    private String nickName; //会员昵称
    private String phoneNum; //会员电话
    private String email; // 会员邮箱

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getNickName() {
        return nickName;
    }

    public void setNickName(String nickName) {
        this.nickName = nickName;
    }

    public String getPhoneNum() {
        return phoneNum;
    }

    public void setPhoneNum(String phoneNum) {
        this.phoneNum = phoneNum;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    @Override
    public String toString() {
        return "Member{" +

2.2 编写持久层接口

@Repository
public interface OrdersDao {
    /**
     * 查询所有订单
     * @return
     */
    @Select("select * from orders")
    @Results({
            @Result(id = true, property = "id", column = "id"),
            @Result(property = "orderNum", column = "orderNum"),
            @Result(property = "orderTime", column = "orderTime"),
            @Result(property = "peopleCount", column = "peopleCount"),
            @Result(property = "orderDesc", column = "orderDesc"),
            @Result(property = "payType", column = "payType"),
            @Result(property = "orderStatus", column = "orderStatus"),
            @Result(property = "product", column = "productId",one = @One(select = "com.zt.dao.ProductDao.findById")),
    })
    List<Orders> findAll() throws Exception;
}


@Repository
public interface ProductDao {

    /**
     * 查询单个产品
     * @param id
     * @return
     * @throws Exception
     */
    @Select("select * from product where id=#{id}")
    Product findById(Integer id) throws Exception;
}

2.3 编写业务层接口和实现类

public interface OrdersService {
    /**
     * 查询所有订单
     * @return
     * @throws Exception
     */
    List<Orders> findAll() throws Exception;
}

@Transactional
@Service("ordersService")
public class OrdersServiceImpl implements OrdersService {
    @Autowired
    private OrdersDao ordersDao;

    /**
     * 查询所有订单
     * @return
     * @throws Exception
     */
    @Override
    public List<Orders> findAll() throws Exception {
        return ordersDao.findAll();
    }
}

2.4 编写控制层

@Controller
@RequestMapping("/orders")
public class OrdersController {
    @Autowired
    private OrdersService ordersService;

    @RequestMapping("/findAll.do")
    public ModelAndView findAll() throws Exception {
        ModelAndView modelAndView = new ModelAndView();
        List<Orders> orders = ordersService.findAll();
        modelAndView.addObject("ordersList",orders);
        modelAndView.setViewName("orders-list");

        return modelAndView;
    }
}

2.5 编写 JSP 页面

在 pages 包中创建 orders-list.jsp

3. 实现分页查询订单操作

3.1 PageHelper 介绍

PageHelper 是国内非常优秀的一款开源的 MyBatis 分页插件，它支持基本主流与常用的数据库。

3.2 PageHelper 的使用

  1. 导入依赖坐标

    <dependency>
    <groupId>com.github.pagehelper</groupId>
    <artifactId>pagehelper</artifactId>
    <version>5.1.2</version>
</dependency>

  2. 在 applicationContext.xml 中，在配置 SqlSessionFactory 工厂中传入 PageHelper 的插件

    <!-- 配置 SqlSessionFactory 工厂 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <!-- 传入PageHelper的插件 -->
    <property name="plugins">
        <array>
            <!-- 传入插件的对象 -->
            <bean class="com.github.pagehelper.PageInterceptor">
                <property name="properties">
                    <props>
                        <prop key="helperDialect">mysql</prop>
                        <prop key="reasonable">true</prop>
                    </props>
                </property>
            </bean>
        </array>
    </property>
</bean>

  3. 编写业务层

    public interface OrdersService {
    /**
     * 分页查询所有订单
     * @param pageNum 当前页数
     * @param pageSize 每页条数
     * @return
     * @throws Exception
     */
    List<Orders> findAllByPage(int pageNum, int pageSize) throws Exception;
}

    @Transactional
@Service("ordersService")
public class OrdersServiceImpl implements OrdersService {
    @Autowired
    private OrdersDao ordersDao;

    /**
     * 分页查询所有订单
     * @param pageNum 当前页数
     * @param pageSize 每页条数
     * @return
     * @throws Exception
     */
    @Override
    public List<Orders> findAllByPage(int pageNum, int pageSize) throws Exception {
        PageHelper.startPage(pageNum,pageSize);
        return ordersDao.findAll();
    }


}

  4. 编写控制层

    @Controller
@RequestMapping("/orders")
public class OrdersController {
    @Autowired
    private OrdersService ordersService;
    
    /**
     * 分页查询所有订单
     * @param pageNum 当前页数
     * @param pageSize 每页条数
     * @return
     * @throws Exception
     */
    @RequestMapping("/findAllByPage.do")
    public ModelAndView findAllByPage(@RequestParam(name = "pageNum", defaultValue = "1") int pageNum, @RequestParam(name = "pageSize", defaultValue = "5") int pageSize) throws Exception {
        ModelAndView modelAndView = new ModelAndView();
        List<Orders> orders = ordersService.findAllByPage(pageNum, pageSize);
        PageInfo<Orders> ordersPageInfo = new PageInfo<>(orders);
        modelAndView.addObject("pageInfo", ordersPageInfo);
        modelAndView.setViewName("orders-page-list");

        return modelAndView;
    }
}

  5. 编写 JSP 页面

    在 pages 包中创建 orders-page-list.jsp

4. 实现查询订单详情操作

4.1 编写持久层接口

@Repository
public interface OrdersDao {

    /**
     * 查询单个订单详细信息
     *
     * @return
     * @throws Exception
     */
    @Select("select * from orders where id=#{id}")
    @Results({
            @Result(id = true, property = "id", column = "id"),
            @Result(property = "orderNum", column = "orderNum"),
            @Result(property = "orderTime", column = "orderTime"),
            @Result(property = "peopleCount", column = "peopleCount"),
            @Result(property = "orderDesc", column = "orderDesc"),
            @Result(property = "payType", column = "payType"),
            @Result(property = "orderStatus", column = "orderStatus"),
            @Result(property = "product", column = "productId", one = @One(select = "com.zt.dao.ProductDao.findById")),
            @Result(property = "member", column = "memberId", one = @One(select = "com.zt.dao.MemberDao.findById")),
            @Result(property = "travellers", column = "id",many = @Many(select = "com.zt.dao.TravellerDao.findById"))
    })
    Orders findById(int id) throws Exception;
}


public interface MemberDao {
    /**
     * 查询单个会员
     * @param id
     */
    @Select("select * from member where id=#{id}")
    Member findById(int id) throws Exception;
}


public interface TravellerDao {
    /**
     * 查询旅客
     * @param id
     * @return
     * @throws Exception
     */
    @Select("select * from traveller where id in(select travellerId from order_traveller where orderId = #{id})")
    List<Traveller> findById(int id) throws Exception;
}

4.2 编写业务层接口和实现类

public interface OrdersService {

    /**
     * 查询单个订单详细信息
     * @param id
     * @return
     * @throws Exception
     */
    Orders findById(int id) throws Exception;
}


@Transactional
@Service("ordersService")
public class OrdersServiceImpl implements OrdersService {
    @Autowired
    private OrdersDao ordersDao;

    /**
     * 查询单个订单详细信息
     * @param id
     * @return
     * @throws Exception
     */
    @Override
    public Orders findById(int id) throws Exception {
        return ordersDao.findById(id);
    }
}

4.3 编写控制层

@Controller
@RequestMapping("/orders")
public class OrdersController {
    @Autowired
    private OrdersService ordersService;

    /**
     * 查询单个订单详细信息
     * @param id
     * @return
     * @throws Exception
     */
    @RequestMapping("/findById.do")
    public ModelAndView findById(@RequestParam(name = "id") int id) throws Exception {
        ModelAndView modelAndView = new ModelAndView();
        Orders orders = ordersService.findById(id);
        modelAndView.addObject("orders",orders);
        modelAndView.setViewName("orders-show");

        return modelAndView;
    }
}

4.4 编写 JSP 页面

在 pages 包中创建 orders-show.jsp
