部署流程

@Test
public void testDeployProcess() throws IOException {ClassPathResource classPathResource = new ClassPathResource("/processes/leave.bpmn20.xml");// 部署流程 act_re_procdefDeployment deploy = repositoryService.createDeployment().addInputStream(classPathResource.getPath(), classPathResource.getInputStream()).deploy();System.out.println("deploy = " + deploy);
}

启动流程

@Test
public void testStartProcess() {//启动流程时传递的参数列表 这里根据实际情况 也可以选择不传Map<String, Object> variables = new HashMap<>();variables.put("applyUserId", "12345678"); // 代理人activiti:assignee="${applyUserId}// 获取流程定义的KeyString processDefinitionKey = "myLeave";// 定义businessKeyString businessKey = processDefinitionKey + ":" + "10001"; // 假设模拟请假业务id为1001// 设置启动流程的人（可选）// Authentication.setAuthenticatedUserId("admin");// 启动流程 act_hi_procinst act_ru_variable act_ru_taskProcessInstance processInstance = runtimeService.startProcessInstanceByKey(processDefinitionKey, businessKey, variables);System.out.println("processInstance = " + processInstance);System.out.println("流程实例ID：" + processInstance.getId());
}

查询任务

将启动流程后的流程实例ID更换到下面

@Test
public void queryTaskList() {// 查询任务 act_ru_taskTaskQuery taskQuery = taskService.createTaskQuery().processInstanceId("08badca0-35c4-11ee-b423-18c04dcd4aee") // 流程实例ID.taskAssignee("12345678") // 代理人.orderByTaskCreateTime().asc();List<Task> taskList = taskQuery.list();System.out.println("taskList = " + taskList);
}

填写请假单

将启动流程后的流程实例ID更换到下面

@Test
public void completeLeaveFormTask() {// 根据id查询任务 act_ru_taskTask task = taskService.createTaskQuery().taskId("08bde9e7-35c4-11ee-b423-18c04dcd4aee").singleResult();Map<String, Object> hashMap = new HashMap<>();hashMap.put("applyUserId", "12345678");hashMap.put("leaveDay", 10);hashMap.put("leaveReason", "理由是不限");hashMap.put("leaveTime", new Date());// 完成任务，填写任务则更新为审核任务，任务ID改变taskService.complete(task.getId(), hashMap);
}

部门审批

将启动流程后的流程实例ID更换到下面

@Test
public void departAudit() {Task task = taskService.createTaskQuery().processInstanceId("08badca0-35c4-11ee-b423-18c04dcd4aee").singleResult();// 添加备注Map<String, Object> hashMap = new HashMap<>();hashMap.put("remark", "注意休息");// 部门审批完成任务，任务列表为空taskService.complete(task.getId(), hashMap);
}
