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（http://blog.csdn.net/yangyi22/article/details/9225849）

- //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

- 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：
