通过重构VO实现校验功能
现有个需求,需要添加供应商的页面校验功能,当填写一二级时,供应商是必填项,并且所填的供应商必须是二级分类下的,否则下一步和保存过不去:
解决方案:
1.在页面AM的XXXImpl.java中,
加入引用:import oracle.jbo.ViewObject;
加入如下方法:

1 public void lastCheck() { 2 ZReqLinesVOImpl zreqVO = this.getZReqLinesVO(); 3 int rowCount = zreqVO.getRowCount(); 4 OAException rowException=null; 5 // System.out.println("1"); 6 // System.out.println("rowCount:"+rowCount); 7 for (int i = 0; i < rowCount; i++) 8 { 9 ZReqLinesVORowImpl vendorRow = (ZReqLinesVORowImpl)zreqVO.getRowAtRangeIndex(i); 10 if(vendorRow.getCate1() != null && vendorRow.getVendorName() == null)//当一二级不为空,供应商名称为空时,提示。 11 {//当填写一二级时,供应商为必填项。请输入第i+1行的供应商。 12 rowException = new OAException("\u5f53\u586b\u5199\u4e00\u4e8c\u7ea7\u65f6\uff0c\u4f9b\u5e94\u5546\u4e3a\u5fc5\u586b\u9879\u3002"+"\u8bf7\u8f93\u5165\u7b2c"+(i+1)+"\u884c\u7684\u4f9b\u5e94\u5546\u3002",OAException.INFORMATION); 13 throw rowException; 14 } 15 if(vendorRow.getVendorName() != null)//当供应商名称不为空时,判断所填的值是否为数据库里存在的供应商 16 { 17 ViewObject tempVO = this.findViewObject("CuxPoHtVendorTempVO"); 18 if (tempVO == null) 19 { 20 StringBuffer stmt = new StringBuffer(1000); 21 String sql = ""; 22 sql += "select distinct t2.vendor_name,substr(t1.Detl_Path||'.',instr(t1.Detl_Path||'.','.',1)+1,instr(t1.Detl_Path||'.','.',1,2)-instr(t1.Detl_Path||'.','.',1,1)-1) detl_id"; 23 sql +=" from SMG_ACT_SUPPLIER_TYPE t1,"; 24 sql +=" po_vendors t2,"; 25 sql +=" SMG_SYS_SUP_CLAS_DETAIL t3"; 26 sql +=" where t1.sup_id = t2.segment1"; 27 sql +=" and t3.detl_id = t1.detl_id"; 28 sql +=" and decode(type_expiry_date,null,sysdate,to_date(substr(type_expiry_date,1,8),'yyyymmdd')) >= sysdate"; 29 sql +=" and decode(TYPE_END_TIME,null,sysdate,to_date(substr(TYPE_END_TIME,1,8),'yyyymmdd')) >= sysdate"; 30 sql +=" and decode(type_temp_time,null,sysdate,to_date(substr(type_temp_time,1,8),'yyyymmdd')) >= sysdate"; 31 sql +=" and t2.attribute11='1'"; 32 stmt.append(sql); 33 // System.out.println(sql); 34 tempVO = this.createViewObjectFromQueryStmt("CuxPoHtVendorTempVO", stmt.toString());//根据上述sql,创建个临时VO 35 } 36 String whareString=" 1=1 "; 37 whareString = whareString + " and VENDOR_NAME = " + "'" + vendorRow.getVendorName() + "'";//把供应商名称当做where条件查询 38 whareString = whareString + " and DETL_ID = " + "'" + vendorRow.getCategory2() + "'";//把二级的detl_id当做where条件查询 39 tempVO.setWhereClause(null); 40 tempVO.setWhereClauseParams(null); 41 tempVO.setWhereClause(whareString); 42 tempVO.executeQuery(); 43 // System.out.println(vendorRow.getVendorName()); 44 // System.out.println(vendorRow.getCategory2());//____________ 45 // System.out.println("2"); 46 Row tempRow = tempVO.first();//判断是否有供应商,若没有,tempRow为空 47 // System.out.println(tempRow != null); 48 if (tempRow == null)//当一级二级不为空,且供应商为随便填的值(即tempRow为空),提示。 49 { 50 // System.out.println("3"); 51 //当填写一二级时,供应商为必填项。请输入第i+1行的供应商。 52 rowException = new OAException("\u5f53\u586b\u5199\u4e00\u4e8c\u7ea7\u65f6\uff0c\u4f9b\u5e94\u5546\u4e3a\u5fc5\u586b\u9879\u3002"+"\u8bf7\u8f93\u5165\u7b2c"+(i+1)+"\u884c\u7684\u4f9b\u5e94\u5546\u3002",OAException.INFORMATION); 53 throw rowException; 54 } 55 } 56 57 58 } 59 }
2.在控制“上一步”、“下一步”和“保存”按钮页面的CO中,调用上述方法:
OAApplicationModule am = pageContext.getApplicationModule(webBean); //-------供应商校验------- am.invokeMethod("lastCheck"); //------------------------
