#  SSM框架搭建

**👵👵👵需求**：

🐱‍🚀🐱‍🚀🐱‍🚀使用ssm框架完成对 account 表的增删改查操作。

💖💖💖最后，框架搭建完后阿红，手写了一个完整的CRUD的demo，请看第9章节···

**步骤分析👀👀👀**

1. 准备数据库和表记录
2. 创建web项目
3. 编写mybatis在ssm环境中可以单独使用
4. 编写spring在ssm环境中可以单独使用
5. spring整合mybatis
6. 编写springMVC在ssm环境中可以单独使用
7. spring整合springMVC

## 1. 准备数据库和表记录

```java
CREATE TABLE `account` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(32) DEFAULT NULL,
`money` double DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
insert  into `account`(`id`,`name`,`money`) values (1,'tom',1000),
(2,'jerry',1000);
```

## 2. 创建web项目

        </dependency>
<!--        mybatis依赖-->
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
            <version>3.5.4</version>
        </dependency>
<!--        junit依赖-->
        <dependency>

            <version>4.12</version>
            <scope>test</scope>
        </dependency>
```

### 3.2 创建Account实体

```java
public class Account {
    private Integer id;
    private String name;
    private String money;
 //省略get和set方法   
}
```

### 3.3 创建AccountDao接口

```java
    /**
     * 查询所有信息
     * @return
     */
     List<Account> findAll();
```

### 3.4 创建AccountDao.xml映射文件

```java
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.weihong.dao.AccountDao">
    <select id="findAll" resultType="Account">
        select * from account
    </select>
</mapper>
```

### 3.5 创建mybatis核心配置文件

**jdbc.properties文件：**

```xml
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/smd
jdbc.username=root
jdbc.password=root
```

**SqlMapConfig.xml文件：**

```java
<?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>
<!--    加载配置文件-->
    <properties resource="jdbc.properties" />
<!--    给实体重命名，方便在sql.xml配置简单-->
    <typeAliases>
        <package name="com.weihong.domain"/>
    </typeAliases>
<!--    配置数据量连接信息-->
    <environments default="dev">
        <environment id="dev">
            <transactionManager type="JDBC"></transactionManager>
            <dataSource type="POOLED">
                <property name="driver" value="${jdbc.driver}"/>
                <property name="url" value="${jdbc.url}"/>
                <property name="username" value="${jdbc.username}"/>
                <property name="password" value="${jdbc.password}"/>
            </dataSource>
        </environment>
    </environments>
    
<!--    加载映射文件-->
    <mappers>
        <package name="com.weihong.dao"/>
    </mappers>
</configuration>

```

### 3.6 测试代码

```java
public class MyTest {

    @Test
    public void findAccountInfo() throws IOException {
        InputStream resourceAsStream = Resources.getResourceAsStream("sqlMapConfig.xml");
        SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(resourceAsStream);
        SqlSession sqlSession = sqlSessionFactory.openSession();
        AccountDao accountDao = sqlSession.getMapper(AccountDao.class);
        List<Account> listAccount = accountDao.findAll();
        for (Account account : listAccount) {
            System.out.println(account);
        }
//        释放资源
        sqlSession.close();

    }
}

```

            <version>5.1.5.RELEASE</version>
        </dependency>
<!--        spring依赖结束 end-->
```

### 4.2 创建AccountService接口

```java
public interface AccountService {

     List<Account> findAccount();

}

```

### 4.3 创建AccountServiceImpl实现

```java
@Service
public class AccountServiceImpl implements AccountService {
    @Override
    public List<Account> findAccount() {
        System.out.println("执行了业务方法！");
        return null;
    }
}
```

### 4.4 创建spring核心配置文件

applicationContext.xml：

```xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="
       	http://www.springframework.org/schema/beans
		http://www.springframework.org/schema/beans/spring-beans.xsd
       	http://www.springframework.org/schema/context

		http://www.springframework.org/schema/tx/spring-tx.xsd
		http://www.springframework.org/schema/aop
		http://www.springframework.org/schema/aop/spring-aop.xsd">

    <!--注解组件扫描-->
    <context:component-scan base-package="com.weihong" />

</beans>
```

### 4.5 测试代码

```java
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class SpringTest {

    @Autowired
    private AccountService accountService;

    @Test
    public void test1(){
        accountService.findAccount();
    }
}
```

### 4.6 测试结果

## 5. spring整合mybatis

### 5.1 整合思想：

将mybatis接口代理对象的创建权交给spring管理，我们就可以把dao的代理对象注入到service中，此时也就完成了spring与mybatis的整合了。

也就是摒弃这几行代码，通过代理对象注入到service中。

![image-20220313150021856](https://gitee.com/jackierchan/jackier-chan_blog/raw/master/img/image-20220313150021856.png)

### 5.2 导入整合包

```java
     <!--spring整合mybatis        -->
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis-spring</artifactId>
            <version>1.3.1</version>
        </dependency>
```

### 5.3 spring配置文件管理mybatis

**注意：此时可以将mybatis主配置文件删除。**


```xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <property name="typeAliasesPackage" value="com.weihong.domain" />
<!--如果要引入mybatis主配置文件，可以通过如下配置 -->
        <!-- <property name="configLocation" value="classpath:SqlMapConfig.xml"/> -->
    </bean>

<!--    映射接口扫描配置，由spring创建代理对象，交给IOC容器 -->
    <bean  class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.weihong.dao" />
    </bean>

</beans>
```

### 5.4 修改AccountServiceImpl

```java
@Service
public class AccountServiceImpl implements AccountService {
    @Autowired
    private AccountDao accountDao;
    @Override
    public List<Account> findAccount() {
        System.out.println("开始查询数据库信息！");
        List<Account> list = accountDao.findAll();
        return list;
    }

}
```

### 5.5 运行结果

## 6. 配置springMVC在ssm环境中可以单独使用

访问到controller里面的方法查询所有账户，并跳转到list.jsp页面进行列表展示

### 6.1 导入相关依赖

```xml
        <!--    spring mvc 依赖 start-->
<!--        引入spring MVC -->

        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>

</web-app>
```

### 6.4 AccountController和 list.jsp

```java
@Controller
public class AccountController {

    @RequestMapping("/findAll")
    public String findAll(Model model){
        Account account = new Account();
        List<Account> list = new ArrayList<>();
        account.setId(1);
        account.setName("张三");
        account.setMoney("1000");
        list.add(account);
        model.addAttribute("list",list);
        return "list";
    }
}
```

```java
              <c:forEach items="${list}" var="account">

              <tr>
                  <td>
                      <input type="checkbox" name="ids" value="${account.id}">
                  </td>
                  <td>${account.id}</td>
                  <td>${account.name}</td>
                  <td>${account.money}</td>
                  <td><a class="btn btn-default btn-sm" href="${pageContext.request.contextPath}/account/findById?id=${account.id}">修改</a>&nbsp;<a class="btn btn-default btn-sm" href="">删除</a></td>
              </tr>
              </c:forEach>
```

### 6.5 配置springMVC核心配置文件

```xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.xsd">

<!--   1. 注解扫描-->
    <context:component-scan base-package="com.weihong.controller" />

<!--    2. mvc注解增强 -->
    <mvc:annotation-driven  />

<!--    3.视图解析 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/" />
        <property name="suffix" value=".jsp" />
    </bean>

<!--    4.实现静态资源映射-->
<!--    方式一：所有静态资源全解开-->
        <mvc:default-servlet-handler />
<!--    方式二：指定资源-->
<!--    <mvc:resources mapping="/js/**" location="/js/" />-->

</beans>

```

## 7. spring整合springMVC

### 7.1 整合思想

spring和springMVC其实根本就不用整合，本来就是一家。

但是我们需要做到spring和web容器整合，让web容器启动的时候自动加载spring配置文件，web容器销毁的时候spring的ioc容器也销毁。

### 7.2 spring和web容器整合

**ContextLoaderListener加载【掌握】**

可以使用spring-web包中的ContextLoaderListener监听器，可以监听servletContext容器的创建和销毁，来同时创建或销毁IOC容器。

```java
<!--    spring 与 web容器整合-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
```

### 7.3 修改AccountController

```java
@Controller
public class AccountController {

    @Autowired
    private AccountService accountService;

    @RequestMapping("/findAll")
    public String findAll(Model model){
        List<Account> account = accountService.findAccount();
        model.addAttribute("list",account);
        return "list";
    }
}

```

## 8. spring配置声明式事务

```java
<!--    spring的声明式事务-->
<!--    1.事务管理器-->
    <bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager" >
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!--2.开始事务注解的支持-->
    <tx:annotation-driven/>
```
