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）

 1 SelectorItemCollection sic = new SelectorItemCollection();  
 2   
 3 //表示获取info所有的属性  
 4   
 5 sic.add(newSelectorItemInfo("*"));  
 6   
 7 //表示获取info上creator上所有的属性  
 8   
 9 sic.add(newSelectorItemInfo("creator.*"));  
10   
11 //表示只获取info上auditor上id，name和number三个属性  
12   
13 sic.add(new SelectorItemInfo("auditor.id"));  
14   
15 sic.add(newSelectorItemInfo("auditor.number"));  
16   
17 sic.add(newSelectorItemInfo("auditor.name"));  
18 
19 特殊的
20 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  
21   
22 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.

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

3,AtsOverTimeBillListHandler这个里面的代码补充

 1 FilterInfo fla = new FilterInfo();
 2               fla.getFilterItems().add(new com.kingdee.bos.metadata.entity.FilterItemInfo("entries.otDate", beginDateTs, CompareType.GREATER_EQUALS));
 3               fla.getFilterItems().add(new com.kingdee.bos.metadata.entity.FilterItemInfo("entries.otDate", endDateTs, CompareType.LESS_EQUALS));
 4               
 5               FilterInfo flb1 = new FilterInfo();
 6               flb1.getFilterItems().add(new com.kingdee.bos.metadata.entity.FilterItemInfo("billState", Integer.valueOf(1), CompareType.EQUALS));
 7               FilterInfo flb2 = new FilterInfo();
 8               flb2.getFilterItems().add(new com.kingdee.bos.metadata.entity.FilterItemInfo("billState", Integer.valueOf(2), CompareType.EQUALS));
 9               FilterInfo flb3 = new FilterInfo();
10               flb3.getFilterItems().add(new com.kingdee.bos.metadata.entity.FilterItemInfo("billState", Integer.valueOf(3), CompareType.EQUALS));
11               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";
12               
13               flb3.getFilterItems().add(new com.kingdee.bos.metadata.entity.FilterItemInfo("PERSON.ID", existsSql, CompareType.EXISTS));
14               
15               FilterInfo flb4 = new FilterInfo();
16               flb4.getFilterItems().add(new com.kingdee.bos.metadata.entity.FilterItemInfo("billState", Integer.valueOf(3), CompareType.EQUALS));
17               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')";
18               
19               flb4.getFilterItems().add(new com.kingdee.bos.metadata.entity.FilterItemInfo("PERSON.ID", notExistsSql, CompareType.NOTEXISTS));
20               
21               FilterInfo flb = new FilterInfo();
22               flb.mergeFilter(flb1, "OR"); //这是一个含有合并过滤(mergeFilter)的案例 可以是"OR"
23               flb.mergeFilter(flb2, "OR");
24               flb.mergeFilter(flb3, "OR");
25               flb.mergeFilter(flb4, "OR");
26               
27               filter.mergeFilter(fla, "AND");//这是一个含有合并过滤(mergeFilter)的案例 也可以是"and"
28               filter.mergeFilter(flb, "AND");

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;
  }

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
