需求：申请人提交流程后，检查明细表填写的发票号是否已存在，如已存在，则更新相应表单字段
1、源代码EInvoiceCheck.java
package weaver.interfaces.workflow.action;import weaver.conn.RecordSet;import weaver.general.BaseBean;import weaver.general.Util;import weaver.interfaces.workflow.action.Action;import weaver.soa.workflow.request.RequestInfo;public class EInvoiceCheck extends BaseBean implements Action {public String execute(RequestInfo request) {try {String requestid = Util.null2String(request.getRequestid());//流程请求IDString mid="";String Invoice = "";RecordSet rs = new RecordSet();RecordSet brs = new RecordSet();RecordSet urs = new RecordSet();String sql = "select d.id,d.Invoice from formtable_main_115 m join formtable_main_115_dt2 d on m.id=d.mainid and m.requestid=" + requestid;rs.execute(sql);while (rs.next()) {mid = Util.null2String(rs.getString("id"));Invoice = Util.null2String(rs.getString("Invoice")).trim();brs.execute("select * from uf_InvoiceInfo where InvoiceNo='"+Invoice+"'");if (brs.next()) {String usql = "update formtable_main_115_dt2 set ispay=0 where id='"+mid+"'";urs.execute(usql);//写具体业务逻辑writeLog("流程附加操作:" + usql);//写入日志}}} catch (Exception e) {// TODO: handle exceptionrequest.getRequestManager().setMessagecontent(e.getMessage());writeLog("节点附加操作异常，请联系系统管理员");return "0";}return SUCCESS;}}
2、将代码放在/weaver/ecology/classbean/weaver/interfaces/workflow/action路径下
3、打开E9后端应用中心，【流程引擎】-【路径管理】-【路径设置】-具体流程-【流转设置】-【节点信息】-【节点前/节点后附加操作】-【外部接口】-【自定义接口动作】-点击+号新建-保存
接口动作名称、接口动作标识：自己命名，不可重复
接口动作类文件 ：weaver.interfaces.workflow.action.EInvoiceCheck，代码存放的路径
