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>

 <!-- 使用JavaBean传递多个参数 -->

 <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());

  }
