同样是搞Java，年薪15W和50W到底差在哪里？   

说明：activiti版本是5.22，并且已将activiti.oracle.drop.engine.sql、activiti.oracle.drop.history.sql、activiti.oracle.drop.identity.sql文件生成；数据库版本是：Oracle9iR2。

源码：

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.RuntimeService;
import org.activiti.engine.TaskService;
import org.activiti.engine.repository.DeploymentBuilder;
import org.activiti.engine.task.Task;

public class Activiti11 {

    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());
        ts.complete(task.getId());
        System.out.println("ok......");
    }

}
