Activiti6：模拟钉钉上面的请假流程(使用web画图并导出xml然后使用java执行流程)

1.声明

当前内容主要为本人学习和测试Activiti6这个工作流的基本操作，模拟钉钉上面的请假流程(简单版)

当前内容主要有：

  1. 使用官方的web-app方式画图
  2. 将当前流程图导出为xml配置
  3. 将xml配置导入项目，并使用java方式加载并实现流程执行

2.画出请假执行流程图

在这里插入图片描述

其中都是使用最简单的元素

重要点：
1.启动当前流程需要三个：员工名称，请假时间，请假类型
在这里插入图片描述
例如下面参数：
在这里插入图片描述
此时发起流程就必须这些参数，注意required设置为true

流程发起后，通过审核人，此时审核人需要一个参数来执行后面是否允许请假通过，同样的设置为approve，设置为boolean类型

在这里插入图片描述
在这里插入图片描述
在这里插入图片描述
之后流程到了条件判断，这里其实就是判断当前的定义的变量approve==true或者approve==false

在这里插入图片描述
在这里插入图片描述
在这里插入图片描述
然后后面的审核人和判断就和这个一样即可完成条件判断(所以这里省略后面的userTask和条件判断)

之后到达抄送人
在这里插入图片描述
在这里插入图片描述
此时流程执行结束

保存后(上面的请假类型是枚举所以需要在生成的xml中修改)

3.将画出的图导出为xml文件

在这里插入图片描述
导出内容如下

4.开始补充部分内容

直接将该xml拷贝到项目中，然后找到enum这个请假类型的地方开始补充
在这里插入图片描述

<activiti:formProperty id="offwork_type" name="请假类型" type="enum" required="true">
	<activiti:value id="illVacation" name="病假"></activiti:value>
  	<activiti:value id="birthVacation" name="产假"></activiti:value>
  	<activiti:value id="ownerVacation" name="个人假"></activiti:value>
</activiti:formProperty>

5.执行java测试

import java.util.HashMap;
import java.util.List;
import java.util.Map;
import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngineConfiguration;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.RuntimeService;
import org.activiti.engine.TaskService;
import org.activiti.engine.runtime.ProcessInstance;
import org.activiti.engine.task.Task;

public class OffWorkActiviti6Test {
    
    
	public static void main(String[] args) {
    
    
		/*
		ProcessEngine processEngine = ProcessEngineConfiguration.createStandaloneInMemProcessEngineConfiguration()
		 * .setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_FALSE)
		 * .setJdbcUrl("jdbc:h2:mem:my-own-db;DB_CLOSE_DELAY=1000")
		 * .setAsyncExecutorActivate(false) .buildProcessEngine();
		 */

		// 1. 加载对应的activiti的xml配置文件
		// ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
		ProcessEngine processEngine = ProcessEngineConfiguration.createStandaloneInMemProcessEngineConfiguration()
				.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE)
				.setJdbcUrl("jdbc:mysql://localhost:3306/hy_activiti6")
				.setJdbcDriver("com.mysql.jdbc.Driver")
				.setJdbcUsername("root")
				.setJdbcPassword("root")
				.setAsyncExecutorActivate(false)
				.buildProcessEngine();
		RepositoryService repositoryService = processEngine.getRepositoryService();
		repositoryService.createDeployment()
				.addClasspathResource("OffWork.bpmn20.xml").deploy();

		System.out .println("Number of process definitions: " + repositoryService.createProcessDefinitionQuery().count());
		
		// 创建一个雇员的名称为：Kermit发起一个请假流程，请1天病假
		String username = "Kermit";
		Map<String, Object> variables = new HashMap<String, Object>();
		variables.put("username", username);
		variables.put("type", "illVacation");
		variables.put("offWorkDays", 1);
		RuntimeService runtimeService = processEngine.getRuntimeService();
		// 这里为发起实际的请假请求
		ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("OffWork", variables);
		
		// Verify that we started a new process instance
		System.out.println("Number of process instances: " + runtimeService.createProcessInstanceQuery().count());
		
		System.out.println("员工：" + username + ",发起" + 1 + "天病假的请求");
		
		// 管理组获取所有的任务请求(包括请假等事项)
		// Fetch all tasks for the management group
		TaskService taskService = processEngine.getTaskService();
		List<Task> tasks = taskService.createTaskQuery().taskCandidateGroup("management").list();
		for (Task task : tasks) {
    
    
			System.out.println("Task available: " + task.getName());
		}

		
		// 同意请求,让下一位进行处理
		Task offWorkTask = tasks.get(0);
		variables = new HashMap<String, Object>();
		variables.put("approve", true);
		taskService.complete(offWorkTask.getId(), variables);
		System.out.println("人事部人员同意请假请求....");
		
		// 再次获取,下一个人的执行流程
		tasks = taskService.createTaskQuery().taskCandidateGroup("management").list();
		for (Task task : tasks) {
    
    
			System.out.println("Task available: " + task.getName());
		}
		
		// 人事部主管同意请求
		offWorkTask = tasks.get(0);
		variables = new HashMap<String, Object>();
		variables.put("approve", true);
		taskService.complete(offWorkTask.getId(), variables);
		System.out.println("人事部主管同意请假请求....");
		
		//系统执行抄送任务给当前的经理和秘书		
		tasks = taskService.createTaskQuery().taskCandidateGroup("system").list();
		for (Task task : tasks) {
    
    
			System.out.println("Task available: " + task.getName());
		}
		// 任务完成
		offWorkTask = tasks.get(0);
		taskService.complete(offWorkTask.getId());
		System.out.println("系统自动转发当前的请假给总经理和秘书....");
	}
}

执行结果：

整个流程执行成功！

6.总结

使用官方的web app的流程设计器和下载xml方式简化了开发步骤，和流程xml的编写，很容易编写(但是要小心传递的参数问题和判断条件问题)
