SSM 环境搭建与产品操作

1. 环境准备

1.1 数据库与表结构

1.1.1 创建用户与授权

数据库我们使用 Oracle
Oracle 为每个项目创建单独 user ， oracle 数据表存放在表空间下，每个用户有独立表空间
创建用户及密码

语法 [ 创建用户 ] ： create user 用户名 identified by 口令 [ 即密码 ] ；
例子： create user test identified by test;

授权

语法： grant connect, resource to 用户名 ;
例子： grant connect, resource to test;

PL/SQL Developer 是一个集成开发环境，专门面向 Oracle 数据库存储程序单元的开发 PL/SQL Developer 侧重于易
用性、代码品质和生产力，充分发挥 Oracle 应用程序开发过程中的主要优势。
连接 oracle 数据库

 创建用户及授权
a) 创建用户

 

 b) 授权

 对象权限是指针对于某一张表的操作权限 , 系统权限是指对表的 CRUD 操作权限 , 角色权限是系统权限的集合 , 我们设置 时，一般是设置角色权限，设置resource 与 connect

1.1.2 创建表

产品表信息描述

 创建表sql

CREATE TABLE product(
id varchar2(32) default SYS_GUID() PRIMARY KEY,
productNum VARCHAR2(50) NOT NULL,
productName VARCHAR2(50),
cityName VARCHAR2(50),
DepartureTime timestamp,
productPrice Number,
productDesc VARCHAR2(500),
productStatus INT,
CONSTRAINT product UNIQUE (id, productNum)
)
insert into PRODUCT (id, productnum, productname, cityname, departuretime, productprice,
productdesc, productstatus)
values ('676C5BD1D35E429A8C2E114939C5685A', 'itcast-002', '北京三日游', '北京', to_timestamp('10-
10-2018 10:10:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), 1200, '不错的旅行', 1);
insert into PRODUCT (id, productnum, productname, cityname, departuretime, productprice,
productdesc, productstatus)
values ('12B7ABF2A4C544568B0A7C69F36BF8B7', 'itcast-003', '上海五日游', '上海', to_timestamp('25-
04-2018 14:30:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), 1800, '魔都我来了', 0);
insert into PRODUCT (id, productnum, productname, cityname, departuretime, productprice,
productdesc, productstatus)
values ('9F71F01CB448476DAFB309AA6DF9497F', 'itcast-001', '北京三日游', '北京', to_timestamp('10-
10-2018 10:10:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), 1200, '不错的旅行', 1);

 1.2 maven工程搭建

1.2.1 创建 maven 工程

 

 

 创建子模块
itcast-ssm-web

itcast-ssm-domain

itcast-ssm-service

itcast-ssm-dao

itcast-ssm-utils

其中创建 itcast-ssm-web 时注意我们选择一个web 工程

1.3 编写实体类

public class Product {
private String id; // 主键
private String productNum; // 编号 唯一
private String productName; // 名称
private String cityName; // 出发城市
private Date departureTime; // 出发时间
private String departureTimeStr;
private double productPrice; // 产品价格
private String productDesc; // 产品描述
private Integer productStatus; // 状态 0 关闭 1 开启
private String productStatusStr;
}

1.4 编写业务接口

public interface IProductService {
List<Product> findAll() throws Exception;
}

1.5 编写持久层接口

public interface IProductDao {
@Select("select * from product")
List<Product> findAll() throws Exception;
}

2.SSM 整合与产品查询

2.1 Spring 环境搭建

2.1.1. 编写 Spring 配置文件 applicationContext.xml

<!-- 配置 spring 创建容器时要扫描的包 -->
<!-- 开启注解扫描，管理service和dao -->
<context:component-scan base-package="com.itheima.ssm.service">
</context:component-scan>
<context:component-scan base-package="com.itheima.ssm.dao">
</context:component-scan>

2.1.2. 使用注解配置业务层

@Service
public class ProductServiceImpl implements IProductService{
@Override
public List<Product> findAll() throws Exception {
return null;
}
}

2.2 Spring MVC 环境搭建

2.2.1.web.xml 配置 Spring MVC 核心控制器

<!-- 配置 spring mvc 的核心控制器 -->
<servlet>
<servlet-name>springmvcDispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 配置初始化参数，用于读取 springmvc 的配置文件 -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<!-- 配置 servlet 的对象的创建时间点：应用加载时创建。取值只能是非 0 正整数，表示启动顺 序 -->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvcDispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!-- 配置 springMVC 编码过滤器 -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<!-- 设置过滤器中的属性值 -->
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<!-- 启动过滤器 -->
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<!-- 过滤所有请求 -->
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>*.do</url-pattern>
</filter-mapping>

2.2.2.Spring MVC 配置文件 springmvc.xml

<!-- 扫描controller的注解，别的不扫描 -->
<context:component-scan base-package="com.itheima.ssm.controller">
</context:component-scan>
<!-- 配置视图解析器 -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- JSP文件所在的目录 -->
<property name="prefix" value="/pages/" />
<!-- 文件的后缀名 -->
<property name="suffix" value=".jsp" />
</bean>
<!-- 设置静态资源不过滤 -->
<mvc:resources location="/css/" mapping="/css/**" />
<mvc:resources location="/img/" mapping="/img/**" />
<mvc:resources location="/js/" mapping="/js/**" />
<mvc:resources location="/plugins/" mapping="/plugins/**" />
<!-- 开启对SpringMVC注解的支持 -->
<mvc:annotation-driven />
<!--
支持AOP的注解支持，AOP底层使用代理技术
JDK动态代理，要求必须有接口
cglib代理，生成子类对象，proxy-target-class="true" 默认使用cglib的方式
-->
<aop:aspectj-autoproxy proxy-target-class="true"/>
</beans>

2.2.3. 编写 Controller

ProductController

@Controller
@RequestMapping("/product")
public class ProductController {
@Autowired
private IProductService productService;
@RequestMapping("/findAll.do")
public ModelAndView findAll() {
return null;
}
}

2.3 Spring 与 Spring MVC 整合

<!-- 配置加载类路径的配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:applicationContext.xml,classpath*:spring-security.xml</param-value>
</context-param>
<!-- 配置监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

2.4 Spring 与 MyBatis 整合

2.4.1. 整合思路

把 mybatis 配置文件（ mybatis.xml ）中内容配置到 spring 配置文件中 同时，把 mybatis 配置文件的内容清掉。

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
</configuration>

注意： 理 由于我们使用的是代理 Dao ， 的模式， Dao 具体实现类由 MyBatis 使用代理方式创建，所以此时mybatis 配置文件不能删。 当我们整合 spring 和 mybatis 时， mybatis 创建的 Mapper.xml 文件名必须和 Dao接口 文件 名一致

2.4.2.Spring 接管 mybatis 的 Session 工厂

db.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=root

<context:property-placeholder location="classpath:db.properties"/>
<!-- 配置连接池 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driver}" />
<property name="jdbcUrl" value="${jdbc.url}" />
<property name="user" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean>
<!-- 把交给IOC管理 SqlSessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
</bean>

2.4.3. 自动扫描所有 Mapper 接口和文件

<!-- 扫描dao接口 -->
<bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.itheima.ssm.dao"/>
</bean>

2.4.4. 配置 Spring 事务

<!-- 配置Spring的声明式事务管理 -->
<!-- 配置事务管理器 -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<tx:annotation-driven transaction-manager="transactionManager"/>

2.5 测试运行

2.5.1. 编写 jsp 页面

2.5.1.1 请求发起页面 index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">

</head>
<body>
<a href="${pageContext.request.contextPath}/product/findAll.do">查询产品信息</a>
</body>
</html>

2.5.1.2 显示产品页面 product-list.jsp

SSM 订单操作

1. 表结构分析

1.1. 订单表信息描述 orders

 productId 描述了订单与产品之间的关系。
memberid 描述了订单与会员之间的关系。
创建表 sql

CREATE TABLE orders(

'E61D65F673D54F68B0861025C69773DB');

实体类

public class Orders {
private String id;
private String orderNum;
private Date orderTime;
private String orderTimeStr;
private int orderStatus;
private int peopleCount;
private Product product;
private List<Traveller> travellers;
private Member member;
private Integer payType;
private String payTypeStr;
private String orderDesc;
//省略getter/setter
}

1.2 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。

创建表sql 

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');

实体类

public class Member {
private String id;
private String name;
private String nickname;
private String phoneNum;
private String email;
//省略getter/setter
}

1.3. 旅客表信息描述 traveller

 创建表sql

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);

实体类

public class Traveller {
private String id;
private String name;
private String sex;
private String phoneNum;
private Integer credentialsType;
private String credentialsTypeStr;
private String credentialsNum;
private Integer travellerType;
private String travellerTypeStr;
//省略getter/setter
}

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。

 创建表sql 

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 ('0E7231DC797C486290E8713CA3C6ECCC', '3FE27DF2A4E44A6DBC5D0FE4651D3D3E');
insert into ORDER_TRAVELLER (orderid, travellerid)
values ('2FF351C4AC744E2092DCF08CFD314420', '3FE27DF2A4E44A6DBC5D0FE4651D3D3E');
insert into ORDER_TRAVELLER (orderid, travellerid)
values ('3081770BC3984EF092D9E99760FDABDE', 'EE7A71FB6945483FBF91543DBE851960');
insert into ORDER_TRAVELLER (orderid, travellerid)
values ('55F9AF582D5A4DB28FB4EC3199385762', '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 ('A0657832D93E4B10AE88A2D4B70B1A28', '3FE27DF2A4E44A6DBC5D0FE4651D3D3E');
insert into ORDER_TRAVELLER (orderid, travellerid)
values ('CA005CF1BE3C4EF68F88ABC7DF30E976', 'EE7A71FB6945483FBF91543DBE851960');
insert into ORDER_TRAVELLER (orderid, travellerid)
values ('E4DD4C45EED84870ABA83574A801083E', 'EE7A71FB6945483FBF91543DBE851960');

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： https://github.com/pagehelper/Mybatis-PageHelper
本项目在 gitosc 的项目地址： http://git.oschina.net/free/Mybatis_PageHelper

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
https://oss.sonatype.org/content/repositories/releases/com/github/pagehelper/pagehelper/
http://repo1.maven.org/maven2/com/github/pagehelper/pagehelper/
由于使用了 sql 解析工具，你还需要下载 jsqlparser.jar ：
http://repo1.maven.org/maven2/com/github/jsqlparser/jsqlparser/0.9.5/
3.2.1.2. 使用 Maven
在 pom.xml 中添加如下依赖：

<dependency>
<groupId>com.github.pagehelper</groupId>
<artifactId>pagehelper</artifactId>
<version>最新版本</version>
</dependency>

3.2.2.1 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 MyBatis 配置 xml 中配置拦截器插件
 

<!--
plugins在配置文件中的位置必须符合要求，否则会报错，顺序如下:
properties?, settings?,
typeAliases?, typeHandlers?,
objectFactory?,objectWrapperFactory?,
plugins?,
environments?, databaseIdProvider?, mappers?
-->
<plugins>
<!-- com.github.pagehelper为PageHelper类所在包名 -->
<plugin interceptor="com.github.pagehelper.PageInterceptor">
<!-- 使用下面的方式配置参数，后面会有所有的参数介绍 -->
<property name="param1" value="value1"/>
</plugin>
</plugins>

3.2.2.2. 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：

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 注意其他配置 -->
<property name="plugins">
<array>
<bean class="com.github.pagehelper.PageInterceptor">
<property name="properties">
<!--使用下面的方式配置参数，一行配置一个 -->
<value>
params=value1
</value>
</property>
</bean>
</array>
</property>
</bean>

3.2.3 分页插件参数介绍

1. helperDialect ：分页插件会自动检测当前的数据库链接，自动选择合适的分页方式。 你可以配置
helperDialect 属性来指定分页插件使用哪种方言。配置时，可以使用下面的缩写值：
oracle , mysql , mariadb , sqlite , hsqldb , postgresql , db2 , sqlserver , informix , h2 , sqlserver2012 , derby
特别注意： 使用 SqlServer2012 数据库时，需要手动指定为 sqlserver2012 ，否则会使用 SqlServer2005 的方式进行分页。
你也可以实现 AbstractHelperDialect ，然后配置该属性为实现类的全限定名称即可使用自定义的实现方法。
2. offsetAsPageNum ：默认值为 false ，该参数对使用 RowBounds 作为分页参数时有效。 当该参数设置为true 时，会将 RowBounds 中的 offset 参数当成 pageNum 使用，可以用页码和页面大小两个参数进行分页。
3. rowBoundsWithCount ：默认值为 false ，该参数对使用 RowBounds 作为分页参数时有效。 当该参数设置为 true 时，使用 RowBounds 分页会进行 count 查询。
4. pageSizeZero ：默认值为 false ，当该参数设置为 true 时，如果 pageSize=0 或者 RowBounds.limit = 0 就会查询出全部的结果（相当于没有执行分页查询，但是返回结果仍然是 Page 类型）。
5. reasonable ：分页合理化参数，默认值为 false 。当该参数设置为 true 时， pageNum<=0 时会查询第一页， pageNum>pages （超过总数时），会查询最后一页。默认 false 时，直接根据参数进行查询。
6. params ：为了支持 startPage(Object params) 方法，增加了该参数来配置参数映射，用于从对象中根据属性名取值， 可以配置 pageNum,pageSize,count,pageSizeZero,reasonable ，不配置映射的用默认值， 默认值为 pageNum=pageNum; pageSize=pageSize ; count=countSql ; reasonable=reasonable ; pageSizeZero=pageSizeZero 。
7. supportMethodsArguments ：支持通过 Mapper 接口参数来传递分页参数，默认值 false ，分页插件会从查询方法的参数值中，自动根据上面 params 配置的字段中取值，查找到合适的值时就会自动分页。 使用方法可以参考测试代码中的 com.github.pagehelper.test.basic 包下的 ArgumentsMapTest 和ArgumentsObjTest 。
8. autoRuntimeDialect ：默认值为 false 。设置为 true 时，允许在运行时根据多数据源自动识别对应方言的分页 （不支持自动选择 sqlserver2012 ，只能使用 sqlserver ），用法和注意事项参考下面的 场景五 。
9. closeConn ：默认值为 true 。当使用运行时动态数据源或没有设置 helperDialect 属性自动获取数据库类型时，会自动获取一个数据库连接， 通过该属性来设置是否关闭获取的这个连接，默认 true 关闭，设置为false 后，不会关闭获取的连接，这个参数的设置要根据自己选择的数据源来决定。
3.2.4. 基本使用
PageHelper 的基本使用有 6 种，大家可以查看文档，最常用的有两种
3.2.4.1. RowBounds 方式的调用（了解）
 

List<Country> list = sqlSession.selectList("x.y.selectIf", null, new RowBounds(1, 10));

使用这种调用方式时，你可以使用 RowBounds 参数进行分页，这种方式侵入性最小，我们可以看到，通过RowBounds方式调用只是使用了这个参数，并没有增加其他任何内容。
分页插件检测到使用了 RowBounds 参数时，就会对该查询进行 物理分页 。
关于这种方式的调用，有两个特殊的参数是针对 RowBounds 的，你可以参看上面的分页插件参数介绍
注： 不只有命名空间方式可以用 RowBounds ，使用接口的时候也可以增加 RowBounds 参数，例如：

//这种情况下也会进行物理分页查询
List<Country> selectAll(RowBounds rowBounds);

注意： 由于默认情况下的 RowBounds 无法获取查询总数，分页插件提供了一个继承自 RowBounds 的 PageRowBounds ，这个对象中增加了 total 属性，执行分页查询后，可以从该属性得到查询总数。
3.2.4.2. PageHelper.startPage 静态方法调用（重点）
这种方式是我们要掌握的 在你需要进行分页的 MyBatis 查询方法前调用 PageHelper.startPage 静态方法即可，紧跟在这个方法后的第一个MyBatis 查询方法会被进行分页。

//获取第1页，10条内容，默认查询总数count
PageHelper.startPage(1, 10);
//紧跟着的第一个select方法会被分页
List<Country> list = countryMapper.selectIf(1);

3.3 订单分页查询

3.3.1 Service

@Override
public List<Orders> findAllByPage(int page, int pageSize) throws Exception {
PageHelper.startPage(page, pageSize);
return ordersDao.findAllByPage();
}

3.3.2 Controller

@RequestMapping("/findAll.do")
public ModelAndView findAll(@RequestParam(name = "page", required = true, defaultValue = "1")
Integer page, @RequestParam(name = "pageSize", required = true, defaultValue = "10") Integer
pageSize) throws Exception {
List<Orders> ordersList = ordersService.findAllByPage(page, pageSize);
PageInfo pageInfo = new PageInfo(ordersList);
ModelAndView mv = new ModelAndView();
mv.setViewName("order-list");
mv.addObject("pageInfo", pageInfo);
return mv;
}
