2013年01月04日 ⁄ 综合 ⁄ 共 3395字 ⁄ 字号小中大 ⁄ 评论关闭

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）

				// 完成任务
				taskService.complete(task.getId());

			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：
