一、SSM订单操作

1.表结构分析

1.1.会员表信息描述member

订单与会员之间是多对一关系，我们在订单表中创建一个外键来进行关联。

创建member表

CREATE TABLE member(  id varchar2(32) default SYS_GUID() PRIMARY KEY,  NAME VARCHAR2(20),  nickname VARCHAR2(20),  phoneNum VARCHAR2(20),  email VARCHAR2(20))insert into MEMBER (id, name, nickname, phonenum, email)values ('E61D65F673D54F68B0861025C69773DB', '张三', '小三', '18888888888', 'zs@163.com');

1.2.订单表信息描述 orders

CREATE TABLE orders(id varchar2(32) default SYS_GUID() PRIMARY KEY,orderNum VARCHAR2(20) NOT NULL UNIQUE,orderTime timestamp,peopleCount INT,orderDesc VARCHAR2(500),payType INT,orderStatus INT,productId varchar2(32),memberId varchar2(32),FOREIGN KEY (productId) REFERENCES product(id),FOREIGN KEY (memberId) REFERENCES member(id))insert into ORDERS (id, ordernum,productid, memberid)values ('0E7231DC797C486290E8713CA3C6ECCC', '12345', to_timestamp('02-03-2018 12:00:00.000000','dd-mm-yyyy hh24:mi:ss.ff'), 2, '没什么', 0, 1, '676C5BD1D35E429A8C2E114939C5685A','E61D65F673D54F68B0861025C69773DB');insert into ORDERS (id, ordernum, ordertime, peoplecount, orderdesc, paytype, orderstatus,productid, memberid)values ('5DC6A48DD4E94592AE904930EA866AFA', '54321', to_timestamp('02-03-2018 12:00:00.000000','dd-mm-yyyy hh24:mi:ss.ff'), 2, '没什么', 0, 1, '676C5BD1D35E429A8C2E114939C5685A','E61D65F673D54F68B0861025C69773DB');insert into ORDERS (id, ordernum, ordertime, peoplecount, orderdesc, paytype, orderstatus,productid, memberid)values ('2FF351C4AC744E2092DCF08CFD314420', '67890', to_timestamp('02-03-2018 12:00:00.000000','dd-mm-yyyy hh24:mi:ss.ff'), 2, '没什么', 0, 1, '12B7ABF2A4C544568B0A7C69F36BF8B7','E61D65F673D54F68B0861025C69773DB');insert into ORDERS (id, ordernum, ordertime, peoplecount, orderdesc, paytype, orderstatus,productid, memberid)values ('A0657832D93E4B10AE88A2D4B70B1A28', '98765', to_timestamp('02-03-2018 12:00:00.000000','dd-mm-yyyy hh24:mi:ss.ff'), 2, '没什么', 0, 1, '12B7ABF2A4C544568B0A7C69F36BF8B7','E61D65F673D54F68B0861025C69773DB');insert into ORDERS (id, ordernum, ordertime, peoplecount, orderdesc, paytype, orderstatus,productid, memberid)values ('E4DD4C45EED84870ABA83574A801083E', '11111', to_timestamp('02-03-2018 12:00:00.000000','dd-mm-yyyy hh24:mi:ss.ff'), 2, '没什么', 0, 1, '12B7ABF2A4C544568B0A7C69F36BF8B7','E61D65F673D54F68B0861025C69773DB');insert into ORDERS (id, ordernum, ordertime, peoplecount, orderdesc, paytype, orderstatus,productid, memberid)values ('96CC8BD43C734CC2ACBFF09501B4DD5D', '22222', to_timestamp('02-03-2018 12:00:00.000000','dd-mm-yyyy hh24:mi:ss.ff'), 2, '没什么', 0, 1, '12B7ABF2A4C544568B0A7C69F36BF8B7','E61D65F673D54F68B0861025C69773DB');insert into ORDERS (id, ordernum, ordertime, peoplecount, orderdesc, paytype, orderstatus,productid, memberid)values ('55F9AF582D5A4DB28FB4EC3199385762', '33333', to_timestamp('02-03-2018 12:00:00.000000','dd-mm-yyyy hh24:mi:ss.ff'), 2, '没什么', 0, 1, '9F71F01CB448476DAFB309AA6DF9497F','E61D65F673D54F68B0861025C69773DB');insert into ORDERS (id, ordernum, ordertime, peoplecount, orderdesc, paytype, orderstatus,productid, memberid)values ('CA005CF1BE3C4EF68F88ABC7DF30E976', '44444', to_timestamp('02-03-2018 12:00:00.000000','dd-mm-yyyy hh24:mi:ss.ff'), 2, '没什么', 0, 1, '9F71F01CB448476DAFB309AA6DF9497F','E61D65F673D54F68B0861025C69773DB');insert into ORDERS (id, ordernum, ordertime, peoplecount, orderdesc, paytype, orderstatus,productid, memberid)values ('3081770BC3984EF092D9E99760FDABDE', '55555', to_timestamp('02-03-2018 12:00:00.000000','dd-mm-yyyy hh24:mi:ss.ff'), 2, '没什么', 0, 1, '9F71F01CB448476DAFB309AA6DF9497F','E61D65F673D54F68B0861025C69773DB');

1.3.旅客表信息描述 traveller

CREATE TABLE traveller(	id varchar2(32) default SYS_GUID() PRIMARY KEY,	NAME VARCHAR2(20),	sex VARCHAR2(20),	phoneNum VARCHAR2(20),	credentialsType INT,	credentialsNum VARCHAR2(50),	travellerType INT)insert into TRAVELLER (id, name, sex, phonenum, credentialstype, credentialsnum, travellertype)values ('3FE27DF2A4E44A6DBC5D0FE4651D3D3E', '张龙', '男', '13333333333', 0,'123456789009876543', 0);insert into TRAVELLER (id, name, sex, phonenum, credentialstype, credentialsnum, travellertype)values ('EE7A71FB6945483FBF91543DBE851960', '张小龙', '男', '15555555555', 0,'987654321123456789', 1);

旅客与订单之间是多对多关系，所以我们需要一张中间表（order_traveller）来描述。

CREATE TABLE order_traveller(  orderId varchar2(32),  travellerId varchar2(32),  PRIMARY KEY (orderId,travellerId),  FOREIGN KEY (orderId) REFERENCES orders(id),  FOREIGN KEY (travellerId) REFERENCES traveller(id))insert into ORDER_TRAVELLER (orderid, travellerid)values ('96CC8BD43C734CC2ACBFF09501B4DD5D', '3FE27DF2A4E44A6DBC5D0FE4651D3D3E');insert into ORDER_TRAVELLER (orderid, travellerid)values ('2FF351C4AC744E2092DCF08CFD314420', '3FE27DF2A4E44A6DBC5D0FE4651D3D3E');insert into ORDER_TRAVELLER (orderid, travellerid)values ('5DC6A48DD4E94592AE904930EA866AFA', 'EE7A71FB6945483FBF91543DBE851960');insert into ORDER_TRAVELLER (orderid, travellerid)values ('A0657832D93E4B10AE88A2D4B70B1A28', 'EE7A71FB6945483FBF91543DBE851960');insert into ORDER_TRAVELLER (orderid, travellerid)values ('CA005CF1BE3C4EF68F88ABC7DF30E976', '3FE27DF2A4E44A6DBC5D0FE4651D3D3E');insert into ORDER_TRAVELLER (orderid, travellerid)values ('96CC8BD43C734CC2ACBFF09501B4DD5D', 'EE7A71FB6945483FBF91543DBE851960');insert into ORDER_TRAVELLER (orderid, travellerid)values ('5DC6A48DD4E94592AE904930EA866AFA', '3FE27DF2A4E44A6DBC5D0FE4651D3D3E');insert into ORDER_TRAVELLER (orderid, travellerid)values ('96CC8BD43C734CC2ACBFF09501B4DD5D', 'EE7A71FB6945483FBF91543DBE851960');insert into ORDER_TRAVELLER (orderid, travellerid)values ('5DC6A48DD4E94592AE904930EA866AFA', 'EE7A71FB6945483FBF91543DBE851960');

1.4.创建对应表的实体类

2.2 创建IOrdersDao接口

package com.itzheng.ssm.dao;import com.itzheng.ssm.domain.Orders;import org.apache.ibatis.annotations.One;import org.apache.ibatis.annotations.Result;import org.apache.ibatis.annotations.Results;import org.apache.ibatis.annotations.Select;import java.util.List;public interface IOrdersDao {
       @Select("select * from orders")    @Results({
               @Result(id=true,column = "id",property = "id"),            @Result(column = "orderNum",property = "orderNum"),            @Result(column = "orderTime",property = "orderTime"),            @Result(column = "orderStatus",property = "orderStatus"),            @Result(column = "peopleCount",property = "peopleCount"),            @Result(column = "payType",property = "payType"),            @Result(column = "orderDesc",property = "orderDesc"),            @Result(column = "productId",property = "product",one = @One(select =                    "com.itzheng.ssm.dao.IProductDao.findById"))    })    List
   
     findAll() throws Exception;}
   

2.3 修改IProductDao，添加通过i查询的方法

//根据id查询产品    @Select("select * from product where id=#{id}")    public Product findById(String id) throws Exception;

3.订单分页查询

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，例如mysql、

oracle、mariaDB、DB2、SQLite、Hsqldb等。 本项目在 github 的项目地址： 本项目在 gitosc 的项目地址：

3.2 PageHelper使用

3.2.1.集成

引入分页插件有下面2种方式，推荐使用 Maven 方式。

3.2.1.1. 引入 Jar 包

你可以从下面的地址中下载最新版本的 jar 包

由于使用了sql 解析工具，你还需要下载 jsqlparser.jar：

3.2.1.2. 使用 Maven

在 pom.xml 中添加如下依赖：

               
    
     com.github.pagehelper
                
    
     pagehelper
                
    
     5.1.10
     
   

3.2. 2.配置

特别注意，新版拦截器是 com.github.pagehelper.PageInterceptor 。 com.github.pagehelper.PageHelper 现

在是一个特殊的 dialect 实现类，是分页插件的默认实现类，提供了和以前相同的用法。 3.2.2.1. 在 Spring 配置文件中配置拦截器插件 使用 spring 的属性配置方式，可以使用 plugins 属性像下面这样配置：

       
           
            
            
                
                     
                      
                          
                               
         
         
          oracle
          
         
          true
          
                            
                       
                  
             
        
   

3.3 订单分页查询

3.3.1 Service，创建接口和实现类

package com.itzheng.ssm.service;import com.itzheng.ssm.domain.Orders;import java.util.List;public interface IOrdersService {
       public List
   
     findAll(int page, int pageSize) throws Exception;}
   

实现类当中

package com.itzheng.ssm.service.impl;import com.github.pagehelper.PageHelper;import com.itzheng.ssm.dao.IOrdersDao;import com.itzheng.ssm.domain.Orders;import com.itzheng.ssm.service.IOrdersService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Transactional;import java.util.List;@Service@Transactionalpublic class OrdersServiceImpl implements IOrdersService {
       @Autowired    IOrdersDao ordersDao;    @Override    public List
   
     findAll(int page, int pageSize) throws Exception {
           PageHelper.startPage(page, pageSize);        return ordersDao.findAll();    }}
   

3.3.2 Controller

OrdersController当中

package com.itzheng.ssm.controller;import com.github.pagehelper.PageInfo;import com.itzheng.ssm.domain.Orders;import com.itzheng.ssm.service.IOrdersService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.servlet.ModelAndView;import java.util.List;@Controller@RequestMapping("/orders")public class OrdersController {
       @Autowired    IOrdersService ordersService;    @RequestMapping("/findAll.do")    public ModelAndView findAll(@RequestParam(name = "page", required = true, defaultValue = "1") int page, @RequestParam(name = "size", required = true, defaultValue = "4") int size) throws Exception {
           ModelAndView mv = new ModelAndView();        List
   
     ordersList = ordersService.findAll(page, size);        //PageInfo就是一个分页Bean        PageInfo pageInfo=new PageInfo(ordersList);        mv.addObject("pageInfo",pageInfo);        mv.setViewName("orders-page-list");        return mv;    }}
   

3.3.3 运行测试

设置每页展示的条数

4.订单详情的查询实现

4.1 通过id查询

（1）dao的实现

IOrdersDao的findById方法

@Select("select * from orders where id=#{id}")    @Results({
               @Result(id=true,column = "id",property = "id"),            @Result(column = "orderNum",property = "orderNum"),            @Result(column = "orderTime",property = "orderTime"),            @Result(column = "orderStatus",property = "orderStatus"),            @Result(column = "peopleCount",property = "peopleCount"),            @Result(column = "payType",property = "payType"),            @Result(column = "orderDesc",property = "orderDesc"),            @Result(column = "productId",property = "product",one = @One(select =                    "com.itzheng.ssm.dao.IProductDao.findById")),            @Result(column = "id",property = "travellers",many = @Many(select =                    "com.itzheng.ssm.dao.ITravellerDao.findByOrdersId")),            @Result(column = "memberId",property = "member",one = @One(select =                    "com.itzheng.ssm.dao.IMemberDao.findById")),    })    Orders findById(String id) throws Exception;

IMemberDao的findById方法

ITravellerDao.findByOrdersId方法

package com.itzheng.ssm.dao;import com.itzheng.ssm.domain.Traveller;import org.apache.ibatis.annotations.Select;import java.util.List;public interface ITravellerDao {
       @Select("select * from traveller where id in (select travellerId from order_traveller where orderId=#{ordersId})")    List
   
     findByOrdersId(String ordersId) throws Exception;}
   

（2）Service的实现

Orders findById(String ordersId)  throws Exception ;

@Override    public Orders findById(String ordersId) throws Exception  {
           return ordersDao.findById(ordersId);    }

（3）在OrdersController当中创建findById方法

@RequestMapping("/findById.do")    public ModelAndView findById(@RequestParam(name = "id",required = true) String ordersId) throws Exception {
           ModelAndView mv = new ModelAndView();        Orders  orders = ordersService.findById(ordersId);        mv.addObject("orders",orders);        mv.setViewName("orders-show");        return mv;    }

（4）创建orders-show.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"	pageEncoding="UTF-8"%><%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

运行测试项目

上面证件类型和人群没有显示

（5）修改Traveller类

public String getCredentialsTypeStr() {
           if(credentialsType != null){
               if(credentialsType == 0){
                   credentialsTypeStr = "身份证";            }            if(credentialsType == 1){
                   credentialsTypeStr = "护照";            }            if(credentialsType == 2){
                   credentialsTypeStr = "军官证";            }        }        return credentialsTypeStr;    }

public String getTravellerTypeStr() {
           if(travellerType != null){
               if(travellerType == 0){
                   travellerTypeStr = "成人";            }            if(travellerType == 1){
                   travellerTypeStr = "儿童";            }        }        return travellerTypeStr;    }
