org.activiti.engine.ActivitiObjectNotFoundException: no deployed process definit

今天开始学习Activiti，在搭建环境的时候出现了很多错误。其他问题都解决了，唯独下面这个问题纠结了很久。还好最后还是解决了。

 

错误信息：

我的Java代码：

package com.bug315;

 

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.runtime.ProcessInstance;

import org.activiti.engine.task.Task;

 

public class ActivitiTest01 {

 

    public static void main(String[] args) {

        // 创建流程引擎

        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

         

        // 获取流程存储服务组件

        RepositoryService repositoryService = processEngine.getRepositoryService();

         

        // 获取运行时服务组件

        RuntimeService runtimeService = processEngine.getRuntimeService();

         

        // 获取流程任务组件

        TaskService taskService = processEngine.getTaskService();

         

        // 1、部署流程文件

        repositoryService.createDeployment().name("myProcess")

            .addClasspathResource("bpmn/activiti_test01.bpmn").deploy();

         

        // 2、启动流程

        ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("myProcess"); 

                //runtimeService.startProcessInstanceById("myProcess");

        System.out.println(processInstance.getId());

         

        // 3、查询第一个任务

        Task task = taskService.createTaskQuery().singleResult();

        System.out.println("============" + task.getId() + "============");

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

         

        // 4、查询第二个任务

        task = taskService.createTaskQuery().singleResult();

        System.out.println("============" + task.getId() + "============");

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

         

        // 5、流程结束

        task = taskService.createTaskQuery().singleResult();

        System.out.println("============ 任务结束（" + task + "） ============");

    }

     

}

 

解决办法：

    仔细看上面的异常是指定的流程定义ID不存在。再仔细看看我的代码，我的愿意是通过流程定义中<process>元素的id去启动流程。但是我错误写使用了startProcessInstanceById方法。因此将startProcessInstanceById（）方法改为startProcessInstanceByKey()方法就解决问题了。你到act_re_procdef表中去查看ID_字段的格式为：myProcess:1:4，所以根本就不存在ID等于myProcess的流程定义。这些都是初心大意造成的，不知你是否也犯过这种低级错误。

 

部分流程XML代码：

<process id="myProcess" name="My process" isExecutable="true">

 

部分测试代码：

// 2、启动流程

ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("myProcess"); 

// runtimeService.startProcessInstanceById("myProcess"); // 这里调用方法写错了
