javaBean：

/**

public class HotBean {
	private int popId;
	private int popIcoId;
	private int popBgId;
	private int popTemplateId;
	private int popNumber;
	private int popType;
	
	private BgImageBean bgImageBean;
	private IconBean iconBean;
	private TemplateBean templateBean;
	
//	private List<BgImageBean>bgList=new ArrayList<BgImageBean>();
//	private List<IconBean>icoList=new ArrayList<IconBean>();
//	private List<TemplateBean>templateList=new ArrayList<TemplateBean>();
	/**

		// TODO Auto-generated constructor stub
	}

		return bgImageBean;
	}

		this.bgImageBean = bgImageBean;
	}

	}

		this.iconBean = iconBean;
	}


	public TemplateBean getTemplateBean() {
		return templateBean;
	}


	public void setTemplateBean(TemplateBean templateBean) {
		this.templateBean = templateBean;
	}

		return popId;
	}
	public void setPopId(int popId) {
		this.popId = popId;
	}
	public int getPopIcoId() {
		return popIcoId;
	}
	public void setPopIcoId(int popIcoId) {
		this.popIcoId = popIcoId;
	}
	public int getPopBgId() {

		return popType;
	}

		this.popType = popType;
	}

	}

	public int getPopNumber() {

}

  测试程序：

public class Test{
public void testQuery1(){
		HotMaterialManagerDaoImpl daoImpl=new HotMaterialManagerDaoImpl();
		List<HotBean> list = daoImpl.queryAllHot();
		for (HotBean hotBean : list) {
			System.out.println(hotBean.getPopNumber());
		}
	}
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		HotManagerTest test=new HotManagerTest();
		test.testQuery1();
//		test.testCancel();
//		test.testUpdate();
	}
}

  实现1对1的关键地方是：

                               <association property="bgImageBean" column="POP_BG_ID" javaType="bgImage"
		 	  select="pageSelectBg"></association>
		 <association property="iconBean" column="POP_ICO_ID" javaType="bgImage"
		 	  select="pageSelectIcon"></association>
		<association property="templateBean" column="POP_TEMPLATE_ID" javaType="bgImage"
			  select="pageSelectTemplate"></association>

   在select="pageSelectBg“，查询中传入int 参数，关联对象。。
