spring整合mybatis

在mybaits的基础上进行整合，之前的代码在mybatis的find那篇。

1.导入spring-mybatis的jar包。

    org.mybatis
    mybatis-spring
    2.0.6

2.创建spring-dao.xml配置文件，这个是用来整合mybatis的数据库，创建

sqlSessionFactory创建

sqlSession。创建

SqlSessionTemplate

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


    
        
        
        
        
    

    
    

        

        
        
        
    

    
    

        
        
    

    
        
    


3.创建接口的实现类，通过实现类来访问数据。

public class MyBookMapperimpl implements MyBookMapper{


    //在开始我们所有操作，都使用sqlSession来执行，spring介入后使用SqlSessionTemplate;

    private SqlSessionTemplate sqlSessionTemplate;

    public void setSqlSessionTemplate(SqlSessionTemplate sqlSessionTemplate){
        this.sqlSessionTemplate = sqlSessionTemplate;
    }

    @Override
    public List selectBooks() {
        MyBookMapper myBookMapper = sqlSessionTemplate.getMapper(MyBookMapper.class);

        return myBookMapper.selectBooks();
    }
}
4.测试

ApplicationContext applicationContext = new ClassPathXmlApplicationContext("spring-dao.xml");
MyBookMapper myBookMapper = applicationContext.getBean("mybookMapper",MyBookMapper.class);
for (Books books : myBookMapper.selectBooks()) {
    System.out.println(books);
