Activiti搭建简单业务流
本章在创建表的基础上进行，如果对Activit创建表不了解的可以看一下Activiti入门
1.绘制流程
在resources下创建diagrams文件夹，右键新建BPMN文件CompanyLeaveProcess.bpmn
使用图标绘制
CompanyLeaveProcess.bpmn.xml代码如下(绘制设置参数后自动生成的)

部署流程定义
@Test
public void deploymentProcessDefine(){
Deployment deployment=processEngine.getRepositoryService()
.createDeployment()//创建部署对象
.name("部署公司请假流程")//设置部署对象名称
.addClasspathResource("diagrams/CompanyLeaveProcess.bpmn.xml")//加载资源文件
.deploy();//创建完成
System.out.println("部署ID"+deployment.getId());
System.out.println("Name"+deployment.getName());
}
运行部署流程后
数据库ACT_RE_PROCDEF与 ACT_RE_DEPLOYMENT会相继生成一个实例
启动实例
@Test public void startProcess(){ System.out.println("开启流程"); Random random=new Random(); int i=random.nextInt(10); Map<String,Object>variables=new HashMap<>(); variables.put("staffName","张三"); variables.put("deploymentHeadName","李组长"); variables.put("managerName1","王经理"); variables.put("managerName2","张经理"); variables.put("day",i); RuntimeService runtimeService=processEngine.getRuntimeService(); String processKey="leaves"; ProcessInstance processInstance=runtimeService.startProcessInstanceByKey(processKey,variables); System.out.println("实例ID----"+processInstance.getId()); }
此时查询数据库select * from ACT_RU_TASK会发现有一个任务开启
获取任务完成流程
@Test public void getStartAndComplete(){ TaskService taskService=processEngine.getTaskService(); /*taskService.setAssignee("",""); while(this.processEngine.getTaskService().createTaskQuery().taskAssignee("王经理").singleResult()!=null){ }*/ while(this.processEngine.getTaskService().createTaskQuery() .processInstanceId("5001").singleResult()!=null){ Task task=taskService.createTaskQuery() .processInstanceId("5001").singleResult(); String taskName=task.getName(); if (taskName.equals("员工申请请假")){ completeStaffTask(task); }else if(taskName.equals("部门领导审核")){ completeEmploymentHeadTask(task); }else{ completeManagerTask(task); } } } private void completeManagerTask(Task task) { System.out.println("经理领导开始审核......."); Map<String,Object>variables=new HashMap<>(); Random random=new Random(); int i=random.nextInt(2); variables.put("result",i); processEngine.getTaskService().complete(task.getId(),variables); System.out.println("经理完成审核......."+task.getName()); } private void completeEmploymentHeadTask(Task task) { System.out.println("部门领导开始审核......."); Map<String,Object>variables=new HashMap<>(); Random random=new Random(); int i=random.nextInt(2); variables.put("deployCheck",i); processEngine.getTaskService().complete(task.getId(),variables); System.out.println("部门领导完成审核......."); } private void completeStaffTask(Task task) { /*Map<String,Object>variables=new HashMap<>(); variables.put("staffName","张三");*/ processEngine.getTaskService().complete(task.getId()); System.out.println("职员已经提交申请......."); }
任务执行完后select * from ACT_HI_TASKINST，select * from ACT_HI_ACTINST两表内会看到流程的历史记录 同时select * from ACT_RU_TASK表中关于此任务信息会消失。
因为任务流程中在组长审核与经理审核时使用随机数，所以才会看到下面很多条记录
