要想整合这两个模块就准备的材料

大配置中的头文件

直接写这个项目上的实体类就能行

 

0.dao层 只有接口没有实现类

public interface IBookDAO {
    public int addBook(Book bok);
}

 

0.service层实现

public class BookServiceImpl implements IBookService {
    //植入dao 对象间的交互
    IBookDAO dao;

    public int addBook(Book book) {
        return dao.addBook(book);
    }

    public IBookDAO getDao() {
        return dao;
    }

    public void setDao(IBookDAO dao) {
        this.dao = dao;
    }
}

jdbc的作用：可以连接数据库properties

0.jdbc.properties文件配置如下：为下面的大配置链接数据库的路径做了铺垫

jdbc.driverClassName=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql:///bookshop

jdbc.user=root

jdbc.password=1234

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
  <property name="dataSource" ref="dataSource" />
</bean>
这里面引一道

<!--大配置路径-->

<property name="configLocation" value="http://www.mamicode.com/classpath:MyBatis-config.xml"></property>

!--big config path-->

 

最后的三个注意点：

 

1.整合引入一个节点

Mybatis-spring 目的识别到（工厂SqlSessionFactoryBean和扫描器

MapperScannerConfigurer，都位于这个包下）

2.注意头文件，加上一个tx事务

3.注意pom.xml注意builder能自动的将src.main.java下的包中的配置文件编译到target目录

  <build>
  <resources>
    <resource>
      <directory>src/main/java</directory>
      <includes>
        <include>**/*.*</include>
      </includes>
    </resource>
  </resources>
</build>
