一个容易的会签实例

一个简单的会签实例

以下例子中采用了jbpm console 的几个实例用户

项目提交人 : ernie .

主管审批 : bert

会签 : ernie , bert , grover

老板审批 : grover

正常流程: 项目金额 >= 500W RMB

提交项目 --> 主管审批 --> 会签 --> 老板审批 --> 审批通过(结束)

正常流程: 项目金额 < 500W RMB

提交项目 --> 主管审批 --> 会签 --> 审批通过(结束)

其中主管审批, 会签, 老板审批 , 不通过, 全部退回给项目提交人修改.

会签中: 所有人全通过, 则通过. 任何一人不通过, 停止其他会签任务.退回给提交人.

流程定义如下:

会签swimlane class

package?net.chenj.jbpm.sample; ?? ??
import?org.jbpm.graph.exe.*; ?? import?org.jbpm.taskmgmt.def.*; ??
import?org.jbpm.taskmgmt.exe.Assignable; ?? ??
public?class?CosingerAssiHandler?implements?AssignmentHandler?{ ?? ??
????private?static?final?long?serialVersionUID?=?1L; ?? ??
????public?void?assign(Assignable?assignable,?ExecutionContext?executionContext)?{ ?? ????????//?从数据库或者ldap?读取会签人设置 ??
????????String[]?a?=?{?"ernie",?"bert",?"grover"?}; ?? ????????assignable.setPooledActors(a); ??
????} ?? ??
} ?? ??

package?net.chenj.jbpm.sample; ?? ??
import?org.jbpm.graph.def.ActionHandler; ?? import?org.jbpm.graph.exe.ExecutionContext; ??
import?org.jbpm.graph.exe.Token; ?? import?org.jbpm.graph.node.TaskNode; ??
import?org.jbpm.taskmgmt.def.Task; ?? import?org.jbpm.taskmgmt.exe.TaskMgmtInstance; ??
?? public?class?CreateTaskInstanceCountersign?implements?ActionHandler?{ ??
?? ????private?static?final?long?serialVersionUID?=?1L; ??
?? ????public?void?execute(ExecutionContext?executionContext)?throws?Exception?{ ??
?? ????????Token?token?=?executionContext.getToken(); ??
????????TaskMgmtInstance?tmi?=?executionContext.getTaskMgmtInstance(); ?? ????????TaskNode?taskNode?=?(TaskNode)?executionContext.getNode(); ??
????????Task?task?=?taskNode.getTask("tc_prj_countersign"); ?? ????????//?从数据库或者ldap?读取会签人设置创建任务实例 ??
????????tmi.createTaskInstance(task,?token).setActorId("ernie"); ?? ????????tmi.createTaskInstance(task,?token).setActorId("bert"); ??
????????tmi.createTaskInstance(task,?token).setActorId("grover"); ?? ??
????} ?? ??
} ??

结束不通过时结束其他会签任务实现

package?net.chenj.jbpm.sample; ?? ??
import?java.util.Collection; ?? import?java.util.Iterator; ??
import?org.jbpm.graph.def.ActionHandler; ?? import?org.jbpm.graph.exe.ExecutionContext; ??
import?org.jbpm.taskmgmt.exe.TaskInstance; ?? import?org.jbpm.taskmgmt.exe.TaskMgmtInstance; ??
?? public?class?TaskEndCountersign?implements?ActionHandler?{ ??
?? ????private?static?final?long?serialVersionUID?=?1L; ??
?? ????public?void?execute(ExecutionContext?executionContext)?throws?Exception?{ ??
?? ???? ??
????????boolean?isDisapprove?=?Boolean.valueOf((String)?executionContext ?? ????????????????.getVariable("isDisapprove")); ??
????????//?如果有一个任务实例拒绝通过则结束除当前任务实例外其他任务实例 ?? ????????if?(isDisapprove)?{ ??
????????????TaskMgmtInstance?tmi?=?executionContext.getTaskMgmtInstance(); ?? ????????????TaskInstance?ti?=?executionContext.getTaskInstance(); ??
????????????final?String?actorId?=?ti.getActorId(); ?? ????????????Collection?c?=?tmi.getSignallingTasks(executionContext); ??
????????????for?(Iterator?it?=?c.iterator();?it.hasNext();)?{ ?? ????????????????TaskInstance?task?=?(TaskInstance)?it.next(); ??
????????????????if?(!(actorId.equals(task.getActorId()))?&&?(!task.hasEnded()))?{ ?? ????????????????????task.end("disapprove"); ??
????????????????} ?? ????????????} ??
????????} ?? ??
????} ?? ??
} ??
