【Activiti工作流】5. 简单请假流程

1. 画出流程图

使用之前安装的Eclipse的流程设计器，画出如下流程图：

1.1 设置开始节点

在properties中选中Main config；设置如下：

然后选中Form,设置如下：

具体操作方式是：点击右边New,
设置请假开始日期：

设置请假结束日期：

设置请假原因：

开始节点对应的XML代码：

 <startEvent id="startevent" name="开始" activiti:initiator="applUserId"><extensionElements><activiti:formProperty id="startDate" name="请假开始日期" type="date" datePattern="yyy-MM-dd" required="true"></activiti:formProperty><activiti:formProperty id="endDate" name="请假结束日期" type="date" datePattern="yyyy-MM-dd" required="true"></activiti:formProperty><activiti:formProperty id="reason" name="请假原因" type="string" required="true"></activiti:formProperty></extensionElements></startEvent>

1.2 设置部门领导审批任务

具体操作如下：

在properties中选中General；设置如下：

选中Main config；设置如下：

选中Form设置如下：

具体设置如下：
设置请假开始日期：

设置请假结束日期：

设置请假原因：

设置审核意见：

审核节点对应XML代码如下：

    <userTask id="deptLeaderAudit" name="部门领导审批" activiti:assignee="wangwu"><extensionElements><activiti:formProperty id="startDate" name="请假开始日期" type="date" datePattern="yyyy-MM-dd" writable="false"></activiti:formProperty><activiti:formProperty id="endDate" name="请假结束日期" type="date" datePattern="yyyy-MM-dd" writable="false"></activiti:formProperty><activiti:formProperty id="reason" name="请假原因" type="string" writable="false"></activiti:formProperty><activiti:formProperty id="deptLeaderApprove" name="审核意见" type="enum" required="true"><activiti:value id="true" name="同意"></activiti:value><activiti:value id="false" name="不同意"></activiti:value></activiti:formProperty></extensionElements></userTask>

需要注意的是Eclipse的流程设计器页面上没有Value属性的设置，所以只能在XML中进行修改配置：

    <userTask id="deptLeaderAudit" name="部门领导审批" activiti:assignee="wangwu"><extensionElements><activiti:formProperty id="startDate" name="请假开始日期" type="date" value="${startDate}" datePattern="yyyy-MM-dd" writable="false"></activiti:formProperty><activiti:formProperty id="endDate" name="请假结束日期" type="date" value="${endDate}" datePattern="yyyy-MM-dd" writable="false"></activiti:formProperty><activiti:formProperty id="reason" name="请假原因" type="string" value="${reason}" writable="false"></activiti:formProperty><activiti:formProperty id="deptLeaderApprove" name="审核意见" type="enum" required="true"><activiti:value id="true" name="同意"></activiti:value><activiti:value id="false" name="不同意"></activiti:value></activiti:formProperty></extensionElements></userTask>

1.3 设置排他网关流出连线的设置

选中一条连线（同意）设置如下：

设置Main Config如下：

设置不同意连线如下：

调整申请任务节点和部门经理审核节点类似。

点击流程图空处，设置如下：

2. 测试流程

2.1 部署流程图

流程图所在的目录如下：

部署流程图代码如下：

package com.activiti;import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.HashMap;
import java.util.List;
import java.util.Map;import org.activiti.engine.FormService;
import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.RuntimeService;
import org.activiti.engine.TaskService;
import org.activiti.engine.form.FormProperty;
import org.activiti.engine.repository.Deployment;
import org.activiti.engine.repository.DeploymentBuilder;
import org.activiti.engine.repository.ProcessDefinition;
import org.activiti.engine.runtime.ProcessInstance;
import org.activiti.engine.task.Task;
import org.junit.jupiter.api.Test;public class LeaveTest {ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();/**部署流程定义*/  @Test  public void deploymentProcessDefinition(){  RepositoryService repositoryService = processEngine.getRepositoryService();  DeploymentBuilder deploymentBuilder=repositoryService.createDeployment(); deploymentBuilder.name("请假流程");deploymentBuilder.addClasspathResource("diagrams/LeaveProcess.bpmn");deploymentBuilder.addClasspathResource("diagrams/LeaveProcess.png");Deployment deployment = deploymentBuilder.deploy();//打印我们的流程信息  System.out.println("流程Id:"+deployment.getId());  System.out.println("流程Name:"+deployment.getName());  System.out.println("——————————————————————————————————————————————————"); }
}

测试结果如下：

流程Id:1
流程Name:请假流程
——————————————————————————————————————————————————

2.2 启动流程图

    /**启动流程引擎*/  @Test  public void startProcessInstance(){RepositoryService repositoryService = processEngine.getRepositoryService();  ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery().processDefinitionKey("LeaveProcess").singleResult();//设置动态表单processEngine.getIdentityService().setAuthenticatedUserId("zhaoliu");Map<String , String > params = new HashMap<String , String  >();SimpleDateFormat  sdt  = new SimpleDateFormat("yyyy-MM-dd");Calendar calendar = Calendar.getInstance();String startDate = sdt.format(calendar.getTime());calendar.add(Calendar.DAY_OF_MONTH, 2);String endDate = sdt.format(calendar.getTime());params.put("startDate", startDate);params.put("endDate", endDate);params.put("reason", "我要休息");FormService formService = processEngine.getFormService();ProcessInstance processInstance = formService.submitStartFormData(processDefinition.getId(), params);System.out.println("流程实例ID："+processInstance.getId());  System.out.println("流程定义ID："+processInstance.getProcessDefinitionId());System.out.println("——————————————————————————————————————————————————"); }

测试结果如下：

流程实例ID：2501
流程定义ID：LeaveProcess:1:4
——————————————————————————————————————————————————

2.3 部门经理审核

审核通过： params.put(“deptLeaderApprove”, “true”);
审核拒绝： params.put(“deptLeaderApprove”, “false”);

 /**部门领导审批通过**/ @Test  public void deptLeaderAuditPass(){  String assignee="wangwu";  FormService formService = processEngine.getFormService();TaskService taskService = processEngine.getTaskService();  Task deptLeaderTask = taskService.createTaskQuery().taskAssignee(assignee).singleResult(); //打印请假人提交的表单信息List<FormProperty> formProperties = formService.getTaskFormData(deptLeaderTask.getId()).getFormProperties();for (FormProperty formProperty : formProperties) {if(!"enum".equals(formProperty.getType().getName())) {System.out.println(  " id ： " + formProperty.getId() +" | name : "+ formProperty.getName() +"| value : "+ formProperty.getValue());}}//审核通过Map<String , String > params = new HashMap<String , String  >();params.put("deptLeaderApprove", "true");formService.submitTaskFormData(deptLeaderTask.getId(), params);System.out.println("部门经理审核通过");boolean isFlag = isEnded(deptLeaderTask.getProcessInstanceId());if(isFlag) {System.out.println("流程结束");System.out.println("——————————————————————————————————————————————————"); }}  public boolean isEnded(String processInstanceId) {RuntimeService runtimeService = processEngine.getRuntimeService();ProcessInstance processInstance = runtimeService.createProcessInstanceQuery().processInstanceId(processInstanceId).singleResult();if(processInstance == null){return true;}else{return false;}}

测试结果如下：

 id ： startDate | name : 请假开始日期| value : 2018-06-07id ： endDate | name : 请假结束日期| value : 2018-06-09id ： reason | name : 请假原因| value : 我要休息
部门经理审核通过
流程结束

调整申请代码与审核代码类似。
