1. 原始方式整合 

CREATE DATABASES ssm;

CREATE TABLE account(
  id int PRIMARY KEY auto_increment,
  name VARCHAR(10),
  money DOUBLE(7,2) 
);

2. 创建 Maven 工程

3. 编写实体类 

public class Account {
    private Integer id;
    private String name;
    private Double money;
}

4. 编写 Mapper 接口 

public interface AccountMapper {
    //保存账户数据
    void save(Account account);
    //查询账户数据
    List<Account> findAll();
}

5. 编写 Service 接口 

public interface AccountService {
    void save(Account account);
    List<Account> findAll();
}

6. 编写 Service 接口实现 

@Service("accountService")
public class AccountServiceImpl implements AccountService {
    @Override
    public void save(Account account)  {
        try {
            InputStream resourceAsStream = Resources.getResourceAsStream("sqlMapperConfig.xml");
            SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(resourceAsStream);
            SqlSession sqlSession = sqlSessionFactory.openSession();
            AccountMapper accountMapper = sqlSession.getMapper(AccountMapper.class);
            accountMapper.save(account);
            sqlSession.commit();
            sqlSession.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    @Override
    public List<Account> findAll() {
        List<Account> accountList = null;
        try {
            InputStream resourceAsStream = Resources.getResourceAsStream("sqlMapperConfig.xml");
            SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(resourceAsStream);
            SqlSession sqlSession = sqlSessionFactory.openSession();
            AccountMapper accountMapper = sqlSession.getMapper(AccountMapper.class);
            accountList = accountMapper.findAll();
            sqlSession.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return accountList;
    }
}

7. 编写 Controller 

@Controller
@RequestMapping("/account")
public class AccountController {
    @Autowired
    private AccountService accountService;

    // produces：设置响应数据的编码格式
    @RequestMapping(value = "/save", produces = "text/html;charset=UTF-8")
    @ResponseBody
    public String save(Account account) throws IOException {
        accountService.save(account);
        return "save success";
    }

    @RequestMapping("/findAll")
    public ModelAndView findAll() throws IOException {
        List<Account> accountList = accountService.findAll();
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.setViewName("accountList");
        modelAndView.addObject("accountList", accountList);
        return modelAndView;
    }
}

8. 编写添加页面 

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
    <h1>保存订单信息</h1>
    <form action="${pageContext.request.contextPath}/account/save" method="post" name="accountForm">
        用户名称：<input type="text" name="name"><br>
        用户金额：<input type="text" name="money"><br>
        <input type="submit" value="保存"><br>
    </form>
</body>
</html>

9. 编写列表页面 

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<html>
<head>
    <title>展示账户数据列表</title>
</head>
<body>
    <table border="1">
        <tr>
            <th>账户id</th>
            <th>账户名称</th>
            <th>账户金额</th>
        </tr>
        <c:forEach items="${accountList}" var="account">
            <tr>
                <th>${account.id}</th>
                <th>${account.name}</th>
                <th>${account.money}</th>
            </tr>
        </c:forEach>
    </table>
</body>
</html>

10. 编写响应的配置文件

12. 测试：查看账户列表

13. 优化：Spring 整合 Mybatis

  1. 将 SQLSessionFactory 配置到Spring容器中
  • 在Spring 核心配置文件中applicationContext.xml，新增配置 数据源信息 、 SQLSessionFactory 配置中、扫描包 
<?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:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="
       http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd
       http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
">


    <!--组件扫描，扫描 mapper 和 service-->
    <context:component-scan base-package="com.xdr630">
        <!--排除controller的扫描-->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"></context:exclude-filter>
    </context:component-scan>



    <!--加载properties文件-->
    <context:property-placeholder location="classpath:jdbc.properties"/>

    <!--配置数据源信息-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driver}"></property>
        <property name="jdbcUrl" value="${jdbc.url}"></property>
        <property name="user" value="${jdbc.username}"></property>
        <property name="password" value="${jdbc.password}"></property>
    </bean>

    <!--配置SQLSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <!--加载 mybatis 核心文件-->
        <property name="configLocation" value="classpath:sqlMapperConfig-spring.xml"></property>
    </bean>

    <!--扫描mapper所在的包，为 mapper 创建实现类-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.xdr630.mapper"></property>
    </bean>
    
</beans>
  • 复制 sqlMapperConfig.xml 名为 sqlMapperConfig-spring.xml ，sqlMapperConfig-spring配置如下： 
<!--定义别名-->
<typeAliases>
    <typeAlias type="com.xdr630.domain.Account" alias="account"/>
    <!--或者，扫包，包下的实体都会定义别名为 类名小写开头的类名 -->
    <!--<package name="com.xdr630.domain"/>-->
</typeAliases>
  1. Spring 核心配置文件 applicationContext.xml 添加事物控制管理 
<!--声明事物控制-->
<!--平台事物管理器-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource"></property>
</bean>

<!--配置事物增强-->
<tx:advice id="txAdvice">
    <tx:attributes>
        <tx:method name="*"/>
    </tx:attributes>
</tx:advice>

<!--事物aop的织入-->
<aop:config>
    <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.xdr630.service.impl.*.*(..))"></aop:advisor>
</aop:config>

14. 添加数据后跳转到列表页面

  • 在 AccountController 修改如下，添加数据后重定向到请求列表的路径
