對EntityViewInfo的理解

 

 

1,EntityViewInfo常常用作bos中接口參數，來做查詢用，其中包含了FilterInfo（過濾）、Selector（指定屬性）以及Sorter（排序）

 

 

 

SelectorItemCollection sic = new SelectorItemCollection();  
  
//表示獲取info所有的屬性  
  
sic.add(newSelectorItemInfo("*"));  
  
//表示獲取info上creator上所有的屬性  
  
sic.add(newSelectorItemInfo("creator.*"));  
  
//表示只獲取info上auditor上id，name和number三個屬性  
  
sic.add(new SelectorItemInfo("auditor.id"));  
  
sic.add(newSelectorItemInfo("auditor.number"));  
  
sic.add(newSelectorItemInfo("auditor.name"));  

特殊的
XXXFactory.getRemoteInstance().getXXXInfo(IObjectPKpk);//直接獲取info，如果info中含有關聯屬性，只能取到關聯屬性的ID  
  
XXXFactory.getRemoteInstance().getXXXInfo(IObjectPKpk, SelectorItemCollection selector);//直接獲取Info，通過在selector中指定需要取哪些屬性，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(); //通過Selector設定屬性
    sic.add(new SelectItemInfo("proposer.id"));//表示只獲取info上proposer上id屬性
    sic.add(new SelectItemInfo("id"));//表示只獲取info上id屬性
    sic.add(new SelectItemInfo("attendDate"));//表示只獲取info上attendDate屬性
    sic.add(new SelectItemInfo("dayType"));//表示只獲取info上dayType屬性
    entityViewInfo.setSelector(sic);//設置屬性
    FilterInfo  filterInfo = new FilterInfo();//建立過濾條件
    filterInfo.getFilterItems().add(new FilterItemInfo("proposer.id",personInfo.getId().toString()));
    filterInfo.getFilterItems().add(new FilterItemInfo("attendDate",newDate,CompareType.GREATER_EQUALS));
    entityViewInfo.setFilter(filterInfo);//設置過濾條件

 

3,AtsOverTimeBillListHandler這個里面的代碼補充

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"); //這是一個含有合並過濾(mergeFilter)的案例 可以是"OR"
              flb.mergeFilter(flb2, "OR");
              flb.mergeFilter(flb3, "OR");
              flb.mergeFilter(flb4, "OR");
              
              filter.mergeFilter(fla, "AND");//這是一個含有合並過濾(mergeFilter)的案例 也可以是"and"
              filter.mergeFilter(flb, "AND");

 

4,

給列表添加過濾條件：

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

 

5，設置列表界面打開時查詢的缺省過濾條件,返回null值屏蔽CU條件 getDefaultFilterForQuery

 

6，

//這是一種比較特殊的用法,目前,還不懂意思
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要養成一個習慣：打補丁前備份整個服務器目錄，有問題就還原
