nrOfInstances}表示完成条件为全部实例完成。flowable:collection${deptInsideMultiInstanceHandler.getUserNames(execution)}表示处理人的集合这里调用了java代码deptInsideMultiInstanceHandler.getUserNames方法返回具体的处理人。下面会贴上代码。在上面的配置基础上再加上【执行监听器】配置如下2.代码实现multiInstanceHandler.getUserNames代码Component(deptInsideMultiInstanceHandler) public class DeptInsideMultiInstanceHandler { public SetString getUserNames(DelegateExecution execution) { SetString candidateUserNames new LinkedHashSet(); // 设置三个实例三个实例的实际处理人分别为技术部处理员001, 产品部处理员001, 售前处理员001 candidateUserNames.addAll(Arrays.asList(技术部处理员001, 产品部处理员001, 售前处理员001)); //如果流程xml配置文件【flowable:assignee】修改为【flowable:candidateGroups】则使用以下设置候选组 // 设置三个实例三个实例的候选组分别为ROLE123456, ROLE456789, DEPT456123 //candidateUserNames.addAll(Arrays.asList(ROLE123456, ROLE456789, DEPT456123)); return candidateUserNames; } }以上代码设置了三个账号表示三个实例的【部门处理员】节点处理人分别为这三个账号3.流程文件flowable.xml:?xml version1.0 encodingUTF-8? bpmn2:definitions xmlns:xsihttp://www.w3.org/2001/XMLSchema-instance xmlns:bpmn2http://www.omg.org/spec/BPMN/20100524/MODEL xmlns:bpmndihttp://www.omg.org/spec/BPMN/20100524/DI xmlns:dchttp://www.omg.org/spec/DD/20100524/DC xmlns:dihttp://www.omg.org/spec/DD/20100524/DI xmlns:flowablehttp://flowable.org/bpmn iddiagram_Process_1761616908502 targetNamespacehttp://flowable.org/bpmn xsi:schemaLocationhttp://www.omg.org/spec/BPMN/20100524/MODEL BPMN20.xsd bpmn2:process idProcess_1761616908502 name分派流程 isExecutabletrue bpmn2:startEvent idks name开始 bpmn2:outgoingFlow_0zttbj2/bpmn2:outgoing /bpmn2:startEvent bpmn2:userTask idzgld name主管领导 flowable:dataTypeINITIATOR flowable:assignee${initiator} flowable:text流程发起人 bpmn2:incomingfq/bpmn2:incoming bpmn2:outgoingld/bpmn2:outgoing /bpmn2:userTask bpmn2:endEvent idjs name结束 bpmn2:incomingbmjs/bpmn2:incoming /bpmn2:endEvent bpmn2:sequenceFlow idbmjs name提交 sourceRefbmnblc targetRefjs / bpmn2:sequenceFlow idfq name发起 sourceRefdj targetRefzgld / bpmn2:sequenceFlow idld name分派 sourceRefzgld targetRefbmnblc / bpmn2:userTask iddj name登记 flowable:dataTypeINITIATOR flowable:assignee${initiator} flowable:text流程发起人 bpmn2:incomingFlow_0zttbj2/bpmn2:incoming bpmn2:outgoingfq/bpmn2:outgoing /bpmn2:userTask bpmn2:sequenceFlow idFlow_0zttbj2 sourceRefks targetRefdj / bpmn2:subProcess idbmnblc name部门内部流程 bpmn2:extensionElements / bpmn2:incomingld/bpmn2:incoming bpmn2:outgoingbmjs/bpmn2:outgoing bpmn2:multiInstanceLoopCharacteristics flowable:collection${deptInsideMultiInstanceHandler.getUserNames(execution)} flowable:elementVariableassignee bpmn2:completionCondition xsi:typebpmn2:tFormalExpression${nrOfCompletedInstances gt;
