我们通常会在EO里面对某些数据进行验证，比如在邀请供应商注册的时候，ORACLE标准逻辑会验证被邀请的供应商是否已经存在。
其验证逻辑在
oracle.apps.pos.schema.server.SupplierRegEOImpl
public void setSupplierName(String value)
{
SupplierRegEntityExpert supplierregentityexpert = getSupplierRegEntityExpert(getOADBTransaction());
if (!supplierregentityexpert.isSupplierValid(value, getSupplierRegId()))
{
throw new OAAttrValException(121, getEntityDef().getFullName(), getPrimaryKey(), "SupplierName", value, "POS", "POS_SUPPREG_EO_ERR1");
} else
{
setAttributeInternal(2, value);
return;
}
}
现由于客户觉得标准的异常提示不够明显，无法区分此供应商是已经正式存在的供应商，还是已经被其他人邀请过的供应商。
所以现决定在保存的时候根据输入的供应商名称进行逻辑判断。
经验证，逻辑判断不能写在processFormRequest中，会先执行EO中的验证。
不过可以写在processFormData中，因为processFormData中的方法是在POST阶段执行，所以不会触发EO中的验证。
public void processFormData(OAPageContext pageContext,OAWebBean webBean){
super.processFormData(pageContext, webBean);
String str1 = pageContext.getParameter("event");
if (("sendInvitation".equals(str1)) || ("SaveNContinueBtnEvent".equals(str1)))
{
OAViewObject SupplierRequestsVO = (OAViewObject)pageContext.getApplicationModule((OAWebBean)webBean.findChildRecursive("RegSupplierRN")).findViewObject("SupplierRequestsVO");
String SupplierName = pageContext.getParameter("SupplierName");
Number SupplierRegId = (Number)SupplierRequestsVO.first().getAttribute("SupplierRegId");
LogUtil.of("validSupplierName ",pageContext).print(pageContext);
validSupplierName(pageContext,webBean,SupplierName,SupplierRegId);
}
}
public void validSupplierName(OAPageContext pageContext,OAWebBean webBean, String SupplierName,Number SupplierRegId){
LogUtil.of("validSupplierName fangfa ",pageContext).print(pageContext);
OraclePreparedStatement oraclepreparedstatement = null;
OracleResultSet oracleresultset = null;
OAApplicationModule am = pageContext.getApplicationModule(webBean);
try{
oraclepreparedstatement = (OraclePreparedStatement)am.getOADBTransaction().createPreparedStatement(" select vendor_id \n" +
"from po_vendors \n" +
"where upper(vendor_name) = upper(:1)\n" +
"and (start_date_active < sysdate OR start_date_active is null) \n" +
"and (end_date_active > sysdate OR end_date_active is null) \n" +
"and rownum = 1", 1);
oraclepreparedstatement.setObject(1,SupplierName);
oracleresultset = (OracleResultSet)oraclepreparedstatement.executeQuery();
if(oracleresultset.next()){
throw new OAException("POS_SUPPREG_EO_ERR1",OAException.ERROR);
}
}
catch(Exception exception1)
{
throw OAException.wrapperException(exception1);
}
try{
oraclepreparedstatement = (OraclePreparedStatement)am.getOADBTransaction().createPreparedStatement("SELECT hou.attribute18,\n" +

OAException exceptionMessage = new OAException("CUX","CUX_SUPPLIER_HAS_BEEN_INVITED",tokens,OAException.ERROR,null);
throw exceptionMessage; //PS1.使用throw直接抛出异常，会导致页面上直接基于EO的字段的数据不会被保留,且不会抛出EO中的验证。
// pageContext.putDialogMessage(exceptionMessage); //PS2.使用putDialogMessage()，页面上的数据被保留，且执行EO中的验证并抛出。
}
