对EntityViewInfo的理解

1,EntityViewInfo常常用作bos中接口参数，来做查询用，其中包含了FilterInfo（过滤）、Selector（指定属性）以及Sorter（排序）

 

SelectorItemCollection sic = new SelectorItemCollection();  
  
//表示获取info所有的属性  
  
sic.add(newSelectorItemInfo("*"));  
  
//表示获取info上creator上所有的属性  
  
sic.add(newSelectorItemInfo("creator.*"));  
  
//表示只获取info上auditor上id，name和number三个属性  
  
sic.add(new SelectorItemInfo("auditor.id"));  
  
sic.add(newSelectorItemInfo("auditor.number"));  
  
sic.add(newSelectorItemInfo("auditor.name"));  

特殊的
XXXFactory.getRemoteInstance().getXXXInfo(IObjectPKpk);//直接获取info，如果info中含有关联属性，只能取到关联属性的ID  
  
XXXFactory.getRemoteInstance().getXXXInfo(IObjectPKpk, SelectorItemCollection selector);//直接获取Info，通过在selector中指定需要取哪些属性，比如  

2,AtsOverTimeBillEditHandler.class中案例,加上自己的理解.

EntityViewInfo  EntityViewInfo =  new EntityViewInfo();//新建接口
    SelectorItemCollection sic = new SelectorItemCollection(); //通过Selector设定属性
    sic.add(new SelectItemInfo("proposer.id"));//表示只获取info上proposer上id属性
    sic.add(new SelectItemInfo("id"));//表示只获取info上id属性
    sic.add(new SelectItemInfo("attendDate"));//表示只获取info上attendDate属性
    sic.add(new SelectItemInfo("dayType"));//表示只获取info上dayType属性
    entityViewInfo.setSelector(sic);//设置属性
    FilterInfo  filterInfo = new FilterInfo();//建立过滤条件
    filterInfo.getFilterItems().add(new FilterItemInfo("proposer.id",personInfo.getId().toString()));
    filterInfo.getFilterItems().add(new FilterItemInfo("attendDate",newDate,CompareType.GREATER_EQUALS));
    entityViewInfo.setFilter(filterInfo);//设置过滤条件

3,AtsOverTimeBillListHandler这个里面的代码补充

FilterInfo fla = new FilterInfo();
              fla.getFilterItems().add(new com.kingdee.bos.metadata.entity.FilterItemInfo("entries.otDate", beginDateTs, CompareType.GREATER_EQUALS));
              fla.getFilterItems().add(new com.kingdee.bos.metadata.entity.FilterItemInfo("entries.otDate", endDateTs, CompareType.LESS_EQUALS));
              
              FilterInfo flb1 = new FilterInfo();
              flb1.getFilterItems().add(new com.kingdee.bos.metadata.entity.FilterItemInfo("billState", Integer.valueOf(1), CompareType.EQUALS));
              FilterInfo flb2 = new FilterInfo();
              flb2.getFilterItems().add(new com.kingdee.bos.metadata.entity.FilterItemInfo("billState", Integer.valueOf(2), CompareType.EQUALS));
              FilterInfo flb3 = new FilterInfo();
              flb3.getFilterItems().add(new com.kingdee.bos.metadata.entity.FilterItemInfo("billState", Integer.valueOf(3), CompareType.EQUALS));
              String existsSql = "SELECT 1 FROM T_HR_ATS_AttendanceResult attenceResult WHERE attenceResult.FPROPOSERID = ENTRIES.FPERSONID AND to_char(attenceResult.Fattencedate,'YYYY-MM-DD') >= '" + beginDate + "'" + " AND to_char(attenceResult.Fattencedate,'YYYY-MM-DD') <= '" + endDate + "'" + " AND to_char(attenceResult.Fattencedate,'YYYY-MM-DD') = to_char(ENTRIES.fotDate,'YYYY-MM-DD')" + " AND attenceResult.FLASTUPDATETIME <= ATSOVERTIMEBILL.FLASTUPDATETIME";
              
              flb3.getFilterItems().add(new com.kingdee.bos.metadata.entity.FilterItemInfo("PERSON.ID", existsSql, CompareType.EXISTS));
              
              FilterInfo flb4 = new FilterInfo();
              flb4.getFilterItems().add(new com.kingdee.bos.metadata.entity.FilterItemInfo("billState", Integer.valueOf(3), CompareType.EQUALS));
              String notExistsSql = "SELECT 1 FROM T_HR_ATS_AttendanceResult attenceResult WHERE attenceResult.FPROPOSERID = ENTRIES.FPERSONID AND to_char(attenceResult.Fattencedate,'YYYY-MM-DD') >= '" + beginDate + "'" + " AND to_char(attenceResult.Fattencedate,'YYYY-MM-DD') <= '" + endDate + "'" + " AND to_char(attenceResult.Fattencedate,'YYYY-MM-DD') = to_char(ENTRIES.fotDate,'YYYY-MM-DD')";
              
              flb4.getFilterItems().add(new com.kingdee.bos.metadata.entity.FilterItemInfo("PERSON.ID", notExistsSql, CompareType.NOTEXISTS));
              
              FilterInfo flb = new FilterInfo();
              flb.mergeFilter(flb1, "OR"); //这是一个含有合并过滤(mergeFilter)的案例 可以是"OR"
              flb.mergeFilter(flb2, "OR");
              flb.mergeFilter(flb3, "OR");
              flb.mergeFilter(flb4, "OR");
              
              filter.mergeFilter(fla, "AND");//这是一个含有合并过滤(mergeFilter)的案例 也可以是"and"
              filter.mergeFilter(flb, "AND");

4,

给列表添加过滤条件：

http://blog.csdn.net/fenyu8/article/details/12085499

5，设置列表界面打开时查询的缺省过滤条件,返回null值屏蔽CU条件 getDefaultFilterForQuery

6，

//这是一种比较特殊的用法,目前,还不懂意思
protected FilterInfo getDefaultFilter(HttpServletRequest request, HttpServletResponse response)
    throws WafException
  {
    FilterInfo filterInfo = super.getDefaultFilter(request, response);
    filterInfo = AtsWebUtils.getDefaultOrgFilter(filterInfo);
    return filterInfo;
  }

7,

做EAS，包括shr要养成一个习惯：打补丁前备份整个服务器目录，有问题就还原
