mybatis传递多个参数

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());  
 
  }
