编写实体类

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

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

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

    public void setMoney(Double money) {
        this.money = money;
    }
}

编写mapper接口

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

创建service接口

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

创建service接口的实现类

public class AccountServiceImpl implements AccountService{

    @Override
    public void save(Account account) {
        try {
            InputStream resourceAsStream = Resources.getResourceAsStream("sqlMapConfig.xml");
            SqlSessionFactory build = new SqlSessionFactoryBuilder().build(resourceAsStream);
            SqlSession sqlSession = build.openSession();
            AccountMapper mapper = sqlSession.getMapper(AccountMapper.class);
            mapper.save(account);
            sqlSession.commit();
            sqlSession.close();
        }catch (IOException e){
            e.printStackTrace();
        }
    }

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

编写controller

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

    //保存
    @RequestMapping("/save")
    @ResponseBody
    public String save(Account account){
        accountService.save(account);
        return  "保存成功";
    }
//    查询
    public ModelAndView findAll(){
        List<Account> all = accountService.findAll();
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.addObject("accountList",all);
        modelAndView.setViewName("accountList");
        return modelAndView;
    }
}

编写页面
编写相关配置文件

配起来太繁琐了，根据自己的需求和之前学的老老实实配置吧

原始的方式整合弊端很多

mybatis整合spring整合

将sqlsessionFactory配置到spring容器中

一个新的配置文件sqlMapConfig-spring.xml

声明事务控制

还是上面那个配置文件：

<!--    平台事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSouce"></property>
    </bean>
<!--    配置事务增强-->
    <tx:advice id="txAdvice">
        <tx:attributes>
            <tx:method name="*"/>
        </tx:attributes>
    </tx:advice>
    
<!--    事务的aop织入-->
    <aop:config>
        <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.xxx.service.*(..))"></aop:advisor>
    </aop:config>
        
        
        <!--    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.xxx.mapper"></property>
    </bean>
