篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了在EORow或者VORow中对数据进行重复性校验相关的知识,希望对你有一定的参考价值。
需求:在设置付款条件时不允许账期+付款方式重复。
由于本次需求仅需要对VO缓存中的数据进行重复性校验,所以仅需进行缓存遍历即可,不需要校验数据库。
方式1,在EORow的进行数据校验。
public void setPaymentTermsId(Number value) { if(value!=null && !"".equals(value) && this.getPaymentMethod()!=null && !"".equals(getPaymentMethod()) ){ validateRepeat(value, getPaymentMethod(), "TERMS"); } setAttributeInternal(PAYMENTTERMSID, value); } public void setPaymentMethod(String value) { if(value!=null && !"".equals(value) && this.getPaymentTermsId()!=null && !"".equals(getPaymentTermsId()) ){ validateRepeat(getPaymentTermsId(), value, "METHOD"); } setAttributeInternal(PAYMENTMETHOD, value); } public void validateRepeat(Number payTerms,String payMethod,String cloumn){ com.sun.java.util.collections.Iterator payIterator = getEntityDef().getAllEntityInstancesIterator(getDBTransaction()); String currentStr = payTerms+"-"+payMethod; while(payIterator.hasNext()){ CuxPoPayProvisionTempEOImpl cachePay = (CuxPoPayProvisionTempEOImpl)payIterator.next(); String validationStr = cachePay.getPaymentTermsId()+"-"+cachePay.getPaymentMethod(); if(currentStr.equals(validationStr)){ if("TERMS".equals(cloumn)){ //发生重复异常时,设置选择值为空,避免选择后提示了异常,选择值仍然放置到了Poplist中 setPaymentTermsId(null); } if("METHOD".equals(cloumn)){ //发生重复异常时,设置选择值为空,避免选择后提示了异常,选择值仍然放置到了Poplist中 setPaymentMethod(null); } throw new OAAttrValException(OAException.TYP_ENTITY_OBJECT, getEntityDef().getFullName(), getPrimaryKey(), "PayProvisionTempId", currentStr, "CUX", "CUX_PO_PAY_PROVI_VALIDATION"); // Message name } } }
2.在VORow中进行校验,
public void setPaymentTermsId(Number value) { if(value!=null && !"".equals(value) && this.getPaymentMethod()!=null && !"".equals(getPaymentMethod()) ){ validateRepeat(value, getPaymentMethod(), "TERMS"); } setAttributeInternal(PAYMENTTERMSID, value); } public String getPaymentMethod() { return (String) getAttributeInternal(PAYMENTMETHOD); } public void validateRepeat(Number payTerms,String payMethod,String cloumn){ CuxPoPayProvisionTempEOImpl tempEO =(CuxPoPayProvisionTempEOImpl)this.getEntity(0); com.sun.java.util.collections.Iterator payIterator = tempEO.getDefinitionObject().getAllEntityInstancesIterator(tempEO.getDBTransaction()); String currentStr = payTerms+"-"+payMethod; while(payIterator.hasNext()){ CuxPoPayProvisionTempEOImpl cachePay = (CuxPoPayProvisionTempEOImpl)payIterator.next(); String validationStr = cachePay.getPaymentTermsId()+"-"+cachePay.getPaymentMethod(); if(currentStr.equals(validationStr)){ if("TERMS".equals(cloumn)){ setPaymentTermsId(null); } if("METHOD".equals(cloumn)){ setPaymentMethod(null); } throw new OAAttrValException(OAException.TYP_VIEW_OBJECT, getViewObject().getFullName(), getKey(), "PayProvisionTempId", currentStr, "CUX", "CUX_PO_PAY_PROVI_VALIDATION"); // Message name } } }
在实际的使用中存在以下需求,不仅要对VO中未提交的缓存进行校验,同时要校验数据库中已存在的值。
方法1.使用标准的同时扫描EORow和TABLE的方式,如果存在结果集,则说明该值已存在。
public boolean attachmentExistsInCacheOrDb( String entityName, String[] pkValues){ boolean atchExists = false; if ( pkValues != null ) { if ( pkValues.length > 5 ) throw new OAException("FND", "ATTCH_TOO_MANY_PKVALUES"); ViewObject vo = null; vo = this.findViewObject("CheckFndAttachedDocumentsVO"); if ( vo == null ){ vo = this.createViewObject("CheckFndAttachedDocumentsVO", "oracle.apps.fnd.server.FndAttachedDocumentsVO"); } vo.addQueryMode(vo.QUERY_MODE_SCAN_DATABASE_TABLES | vo.QUERY_MODE_SCAN_ENTITY_ROWS); ViewCriteria vc = vo.createViewCriteria(); ViewCriteriaRow vcr = vc.createViewCriteriaRow(); //设定标准查询参数,可以多个,参数与Attribute类型一定要一致 vcr.setAttribute("EntityName", entityName); vcr.setAttribute("Pk1Value", pkValues[0]); vcr.setConjunction(ViewCriteriaRow.VCROW_CONJ_AND); vc.addElement(vcr); vc.setCriteriaMode(ViewCriteria.CRITERIA_MODE_QUERY | ViewCriteria.CRITERIA_MODE_CACHE); vo.applyViewCriteria(vc); vo.clearCache(); vo.reset(); vo.setWhereClause(null); vo.setWhereClauseParams(null); vo.setMaxFetchSize(-1); vo.executeQuery(); if(vo.hasNext()){ atchExists = true; } } else { throw new OAException("FND", "ATTCH_PKVALUES_CANNOT_NULL"); } return atchExists; }
方法二:在EO或者VO缓存中进行校验之后再调用查询方法查询数据库中是否已存在值
EORowImpl
public void setItemCategoryId(Number value) { if (value != null) { //此部分与缓存中的行进行校验 //具体实现参考前文 OADBTransaction transaction = getOADBTransaction(); CategoryEntityExpert expert = getCategoryEntityExpert(transaction); if (expert.categoryExists(posMappingId,orgId,orgType, value, orgDepartment)) { throw new OAAttrValException(OAException.TYP_ENTITY_OBJECT, getEntityDef().getFullName(), getPrimaryKey(), "ItemCategoryId", value, "CUX", "CUX_SUP_PERMIT_001"); // Message name } } setAttributeInternal(ITEMCATEGORYID, value); } public static CategoryEntityExpert getCategoryEntityExpert(OADBTransaction txn){ return (CategoryEntityExpert)txn.getExpert(CuxSuppItemCateMappingEOImpl.getDefinitionObject()); } public static CategoryEntityExpert getCategoryEntityExpert(OADBTransaction txn){ return (CategoryEntityExpert)txn.getExpert(CuxSuppItemCateMappingEOImpl.getDefinitionObject()); }
CategoryEntityExpert类
mport oracle.jbo.domain.Number; import oracle.apps.fnd.common.VersionInfo; import oracle.apps.fnd.framework.server.OAEntityExpert; public class CategoryEntityExpert extends OAEntityExpert { public boolean categoryExists(Number posMappingId, Number orgId, String orgType, Number categoryId, String orgDepartment) { boolean exists = false; CategoryIdVVOImpl vvo = (CategoryIdVVOImpl)findValidationViewObject("CategoryIdVVO1"); vvo.initQuery(posMappingId, orgId, orgType, categoryId, orgDepartment); if (vvo.hasNext()) { exists = true; } return exists; } }
CategoryIdVVO1是在AM中实例化的ValidateVO,通常VVO就是用于验证的VO
