springboot整合activity6_ HelloWorld实现（无废话版）--------------------------------------------（二）

分手后的思念是犯贱 2023-02-09 05:24 2阅读 0赞

### 1.源码地址：https://github.com/heidaodageshiwo/springbootactivity ###

### 1.我这里没有用单元测试（@Test）junit  我用的是controller请求的方式来访问 ###

### 2.流程图我是使用的eclipse画的（感觉idea画的有点丑，就没用） ###

### 流程图就画完事了。 ###

// * 部署流程定义
      @RequestMapping("/deployWithClassPath")
      public String deployWithClassPath() {
        Deployment deployment= repositoryService.createDeployment()
            .addClasspathResource("helloworld/Helloworld.bpmn")
            .addClasspathResource("helloworld/Helloworld.png")
            .name("HelloWorld流程")
            .deploy();
        System.out.println("流程部署ID:"+deployment.getId());
        System.out.println("流程部署Name:"+deployment.getName());
        return "deployWithClassPath";
      }

界面请求

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1bmhlaWRhb2Rl_size_16_color_FFFFFF_t_70 6][]

控制台打印

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1bmhlaWRhb2Rl_size_16_color_FFFFFF_t_70 7][]

运行deployWithClassPath方法，部署流程定义，这时候我们的流程定义表会发生一些变化；

首先act\_re\_deployment 流程定义部署表，插入了一条数据；

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1bmhlaWRhb2Rl_size_16_color_FFFFFF_t_70 8][]

然后act\_re\_prodef 流程定义表也会有插入一条数据；这里有流程定义id name key version等重要信息；

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1bmhlaWRhb2Rl_size_16_color_FFFFFF_t_70 9][]

还有一个act\_ge\_bytearray表 用来存资源信息；

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1bmhlaWRhb2Rl_size_16_color_FFFFFF_t_70 10][]

以上是部署流程定义 数据库表里发生的事情；

我们要启动流程实例，这样一个流程才开始；

然后我们继续 ，下面来启动流程实例；

运行start方法；

// *  启动流程实例
      @RequestMapping("/start")
      public String start() {
        ProcessInstance processInstance= runtimeService.startProcessInstanceByKey("myFirstProcess");
        System.out.println("流程实例ID:"+processInstance.getId());
        System.out.println("流程定义ID:"+processInstance.getProcessDefinitionId());
        return "start";
      }

启动流程，数据库流程运行表也会发生相应的变化；

首先是运行时流程任务表：act\_ru\_task；插入了一条任务数据；

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1bmhlaWRhb2Rl_size_16_color_FFFFFF_t_70 11][]

![2020051814355764.png][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1bmhlaWRhb2Rl_size_16_color_FFFFFF_t_70 12][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1bmhlaWRhb2Rl_size_16_color_FFFFFF_t_70 13][]

ID\_是任务id 数据2505    ； PROC\_INST\_ID\_是流程实例ID 2501 以及Name 创建时间等；

接下来是act\_ru\_execution 运行时流程执行表；

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1bmhlaWRhb2Rl_size_16_color_FFFFFF_t_70 14][]

这里的话 存的流程执行相关信息；

接下来是act\_ru\_identitylink 是于执行主体相关信息表；这里是用具体的用户去执行的

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1bmhlaWRhb2Rl_size_16_color_FFFFFF_t_70 15][]

流程实例启动完，接下来就到了helloWorld任务节点；

我们这时候可以来查看下 "张强" 的任务；

// *  查看任务
      @RequestMapping("/findTask")
      public String findTask() {
        List <Task> taskList= taskService.createTaskQuery().taskAssignee("张强").list();
        for(Task task:taskList){
          System.out.println("任务id:"+task.getId());
          System.out.println("任务名称:"+task.getName());
          System.out.println("任务创建时间:"+task.getCreateTime());
          System.out.println("任务委派人:"+task.getAssignee());
          System.out.println("流程定义ID:"+task.getProcessDefinitionId());
          System.out.println("流程实例ID:"+task.getProcessInstanceId());
        }
    
        return "findTask";
      }

运行findTask方法，控制台输出；

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1bmhlaWRhb2Rl_size_16_color_FFFFFF_t_70 16][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1bmhlaWRhb2Rl_size_16_color_FFFFFF_t_70 17][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1bmhlaWRhb2Rl_size_16_color_FFFFFF_t_70 18][]

说明这个用户有任务可以执行；

我们继续走流程 执行completeTask方法；

执行完后，流程其实就已经走完了。

这时候我们再运行findTask，啥都没有输入，已经没有任务了；

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1bmhlaWRhb2Rl_size_16_color_FFFFFF_t_70 19][]

act\_hi\_taskinst 历史流程实例任务表加了一条任务数据；

act\_hi\_procinst 历史流程实例实例表加了一条流程实例相关信息的数据（包括开始时间，结束时间等等信息）；

act\_hi\_identitylink 历史流程实例参数者的表加了一条数据；

act\_hi\_actinst 历史活动节点表加了三条流程活动节点信息的数据（每个流程实例具体的执行活动节点的信息）；
