myeclipse-activiti简单例子1.准备环境 win7 64bit + myeclipse2014 + oracle 10g + activiti-5.17.0 2.实施过程2.1上网导入activiti插件Activiti 提供了基于 Eclipse 插件的开发工具和流程设计工具；联网导入相关包，具体过程如下：导入挺慢的，跟本地网速无关。myeclipse - help - install form siteActiviti BPMN2.0 Designer/designer/update/2.2 在oracle数据库中建表新建 用户activiti、密码activiti，因为跑流程时流程数据都是要入库的导入activiti下载包的表结构2.3 myeclipse建projectfile new other自动产生的结构如下设计一个简单的流程图，只作为简单例子使用，借助插件中的设计出下面的图新建配置文件填写对应的参数新建一个测试包，并建立测试.java文件具体测试源文件package activiti;import org.activiti.engine.ProcessEngine; import org.activiti.engine.ProcessEngines; import org.activiti.engine.RepositoryService; import org.activiti.engine.RuntimeService; import org.activiti.engine.repository.DeploymentBuilder; import org.activiti.engine.runtime.ProcessInstance; import org.activiti.engine.task.Task;import org.activiti.engine.TaskService;public class ActivitiTest public static void main(String args) ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); RepositoryService repositoryService = processEngine.getRepositoryService(); DeploymentBuilder builder = repositoryService.createDeployment(); builder.addClasspathResource(diagrams/MyProcess.bpmn); /获取流程中的任务TASK组件 TaskService ts=processEngine.getTaskService(); builder.deploy(); / select * from ACT_GE_PROPERTY;这时这个表中会多条数据 RuntimeService runtimeService = processEngine.getRuntimeService(); runtimeService.startProcessInstanceByKey(myProcess);/启动流程，ID必须与你配置的一致 /利用taskservice进行任务查询，查询第一个任务，查询后完成 Task task=ts.createTaskQuery().singleResult(); System.out.println(第一个流程任务完成前+task.getName(); plete(task.getId(); System.out.println(ok.); 上面大量报错
