Myibatis3与spring的集成

Myibatis3与ibatis3应该没有较大的改动吧，之前听说Myibatis3不再需要实现DAO接口中的方法，Service层直接调用接口中的方法就OK了，今天整一Demo.

Demo的组织结构图如下：

sql映射文件（BlogMapper.xml):

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
PUBLIC "-//ibatis.apache.org//DTD Mapper 3.0//EN"
"http://ibatis.apache.org/dtd/ibatis-3-mapper.dtd">
<!-- 这里的命名空间，应该为BlogMapper的全限定名，不然会找不到的 -->
<mapper namespace="cn.enjoylife.persistence.BlogMapper">
	<select id="selectBlog" parameterType="int" resultType="Blog" >
		select id,title,content from Blog where id = #{id}
	</select>
	
	<insert id="insertBlog" parameterType="Blog" >
		insert into Blog(id,title,content)
		values(#{id},#{title},#{content})
	</insert>
	
	<update id="updateBlog" parameterType="Blog">
		update Blog set title=#{title},content=#{content}
		where id=#{id}
	</update>
	
	<delete id="deleteBlog" parameterType="int">
		delete from Blog where id=#{id}
	</delete>
</mapper>

DAO接口（BlogMapper.java）:

/**
 * 
 * Blog DAO接口,猜想方法名称对应到BlogMapper.xml中sql id;
 * @author Evan
 *
 */
public interface BlogMapper {
	
	public Blog selectBlog(Integer id);
	
	public void insertBlog(Blog blog);
	
	public void updateBlog(Blog blog);
	
	public void deleteBlog(Integer id);
	
}

Service实现（BlogService.java）:

/**
 * Blog的service实现类
 * @author Evan
 */
@Service
@Transactional
public class BlogService {
	
	@Autowired
	private BlogMapper blogMapper;
	public Blog selectBlog(Integer id) {
		Blog blog=blogMapper.selectBlog(id);
		return blog;
	}
	public void insertBlog(Blog blog){
		blogMapper.insertBlog(blog);
	}
	public void updateBlog(Blog blog){
		blogMapper.updateBlog(blog);
	}
	public void deleteBlog(Integer id){
		blogMapper.deleteBlog(id);
	}
}

总的配置文件（applicationContext.xml）:

<?xml version="1.0" encoding="UTF-8"?>

     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

           </property> 
    </bean>
    <!-- 声明事务管理器 -->

</beans>

测试代码：

public class BlogServiceTest {
	private static BlogService blogService;
	
	@BeforeClass
	public static void setUpBeforeClass() throws Exception {
		ClassPathXmlApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext.xml");
	    blogService=(BlogService)ctx.getBean("blogService");
		System.out.println(blogService);
	}
	
	@Test
	public void testInsertBlog() {
		Blog blog=new Blog();
		blog.setId(100);
		blog.setTitle("today");
		blog.setContent("今天雨下的好大！");
		
		blogService.insertBlog(blog);
	}
	@Test
	public void testSelectBlog() {
		Blog blog=blogService.selectBlog(100);
		System.out.println(blog);
	}
	@Test
	public void testUpdateBlog() {
		Blog blog=new Blog();
		blog.setId(100);
		blog.setTitle("tomorrow");
		blog.setContent("是否还要接着下呢？！");
		
		blogService.updateBlog(blog);
		
		System.out.println(blogService.selectBlog(100));
	}
	@Test
	public void testDeleteBlog() {
		blogService.deleteBlog(100);
	}
}
