Mybatis传递多个参数

ibatis3如何传递多个参数有两个方法：一种是使用Map，另一种是使用JavaBean。

<!--

使用HashMap传递多个参数

parameterType 可以是别名或完全限定名 ,map->java.util.Map,这两个都是可以的

-->

<selectid="selectBlogByMap"parameterType="map"resultType="Blog">

SELECT t.ID, t.title, t.content

FROM blog t

WHERE t.title = #{h_title}

AND t.content =#{h_content}

</select>

<selectid="selectBlogByBean"parameterType="Blog"resultType="Blog">

SELECT t.ID, t.title, t.content

FROM blog t

WHERE t.title = #{title}

AND t.content =#{content}

</select>

/**

* 通过Map传递多个参数

*/

@Test

public void testSelectByMap() {

SqlSession session = sqlSessionFactory.openSession();

Map<String, Object> param=new HashMap<String, Object>();

param.put("h_title", "oracle");

param.put("h_content", "使用序列！");

Blog blog = (Blog)session.selectOne("cn.enjoylife.BlogMapper.selectBlogByMap",param);

session.close();

System.out.println("blog title:"+blog.getTitle());

}

/**

* 通过JavaBean传递多个参数

*/

@Test

public void testSelectByBean() {

SqlSession session = sqlSessionFactory.openSession();

Blog blog=new Blog();

blog.setTitle("oracle");

blog.setContent("使用序列！");

Blog newBlog = (Blog)session.selectOne("cn.enjoylife.BlogMapper.selectBlogByBean",blog);

session.close();

System.out.println("new Blog ID:"+newBlog.getId());

}
