Activiti 简易教程二 version5.10升级version5.12.1

一搭建环境

1.1 JDK 6+

1.2 Ant 1.8.1+

1.3 Eclipse 3.7+

1.4 Activiti -eclipse designer插件安装

1.4.1 先安装GEF插件

1.4.2 安装SVN插件

1.4.3安装Maven插件

1.4.4 最后安装Activiti -eclipse designer

二开始activiti 5.12.1的第一个demo

2.1 建立activiti-demo工程，选择Activiti Project

2.2 将activiti-demo工程的数据库整合为MySQL

2.3 设计activiti-demo工程的流程

以上详细描述参照Activiti 简易教程一 version5.10（/article/9033659.html）

测试类代码 DemoProcessTest.java

[java] view
plain copy

package main.java;

private static String realPath =

"D:\\Java~coding~site\\J2EE-IDE\\Workspace\\workspace[indigo-jee]" +

"\\activiti-512demo\\src\\main\\resources\\diagrams";

public static void main(String[] args) throws Exception {

// 创建 Activiti流程引擎

//方式一 自动寻找activiti.cfg.xml

ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

//方式二 指定加载activiti.cfg.xml

// ProcessEngine processEngine = ProcessEngineConfiguration

// .createProcessEngineConfigurationFromResource("activiti.cfg.xml")

// .buildProcessEngine();

// 取得 Activiti 服务

RepositoryService repositoryService = processEngine.getRepositoryService();

RuntimeService runtimeService = processEngine.getRuntimeService();

// 部署流程定义

repositoryService

.createDeployment()

.addInputStream("DemoProcess.bpmn",new FileInputStream(realPath + "\\DemoProcess.bpmn"))

.addInputStream("DemoProcess.png", new FileInputStream(realPath + "\\DemoProcess.png"))

.deploy();

// 启动流程实例

ProcessInstance instance = processEngine

.getRuntimeService().startProcessInstanceByKey("DemoProcess");

String procId = instance.getId();

System.out.println("procId:"+ procId);

// 获得第一个任务

TaskService taskService = processEngine.getTaskService();

List<Task> tasks = taskService.createTaskQuery().taskDefinitionKey("firstTask").list();

for (Task task : tasks) {

System.out.println("Following task is: taskID -" +task.getId()+" taskName -"+ task.getName());

// 认领任务

taskService.claim(task.getId(), "testUser");

}

// 查看testUser 现在是否能够获取到该任务

tasks = taskService.createTaskQuery().taskAssignee("testUser").list();

for (Task task : tasks) {

System.out.println("Task for testUser: " + task.getName());

// 完成任务

taskService.complete(task.getId());

}

System.out.println("Number of tasks for testUser: "

+ taskService.createTaskQuery().taskAssignee("testUser").count());

// 获取并认领第二个任务

tasks = taskService.createTaskQuery().taskDefinitionKey("secondTask").list();

for (Task task : tasks) {

System.out.println("Following task is : taskID -" +task.getId()+" taskName -"+ task.getName());

taskService.claim(task.getId(), "testUser");

}

//完成第二个任务结束结束流程

for (Task task : tasks) {

taskService.complete(task.getId());

}

// 核实流程是否结束

HistoryService historyService = processEngine.getHistoryService();

HistoricProcessInstance historicProcessInstance = historyService.createHistoricProcessInstanceQuery().processInstanceId(procId).singleResult();

System.out.println("Process instance end time: " + historicProcessInstance.getEndTime());

}

}

依赖jar包说明

Activiti5.10以后的版本已经去掉第三方的jar包，从官网下载的Activiti5.12.1的依赖包仅仅包含activiti相关的jar，目录libs下的jar包如下：







运行测试代码，会发现少了很多依赖包，我的处理的方法是直接从5.10版本导入缺少的jar包，导入后测试代码通过。

jar包：
