对封装的再次理解(容器)
如下：
这两天做一个功能，一个页面有多个同样的对象(List)，进入页面需要遍历list，但是这个list中还有一个list，不是同一张表，一个是另一个的子表，单个对象的保存搞定了，但是遍历时对'对象'的封装没有思绪，根本没往这块想，折腾了好久；
后来想到了容器，不就是一个大箱子里面套了另一个小箱子吗？很常见，但是从来没有往这里想过；
解决方法，在大对象里面再加一个属性，该属性对应的就是小对象的list，在大对象里面set进去就可以了，在页面进行双重遍历即可；相关代码如下：
大对象实体类：
public class CrmCounterguaranteeProWithBLOBs extends CrmCounterguaranteePro { @Getter @Setter private String otherinfo; @Getter @Setter private String remarks; @Getter @Setter public List<CrmReveOwners> reveOwners;//封装的小对象 }
数据关联
// "房产",(2), List<CounterGuaranteeInfo> houses = new ArrayList<CounterGuaranteeInfo>(); //查询抵押反担保共有人、所有人信息 if (null != info && null != info.getGuaranteeInfo()) { CrmReveOwnersExample dyExample =new CrmReveOwnersExample(); dyExample.createCriteria().andProjidEqualTo(info.getGuaranteeInfo().getProjid()).andFaserialidEqualTo(info.getGuaranteeInfo().getFaserialid()); listhousesOwners = crmReveOwnersDao.selectByExample(dyExample); } //封装共有人信息到对象 if (null != listhousesOwners && listhousesOwners.size()>0) { info.getGuaranteeInfo().setReveOwners(listhousesOwners); } houses.add(info);
result.put("houseReveInfos" + revetype, houses);//返回到页面的数据
在页面遍历显示：
