springboot2.0+activiti 7 整合(三)--创建自己的业务流程

使用activiti框架,首先要创建bpmn流程图,这里有两种选择,一种是ide自带的插件(eclipse就不说了,网上各种说好用的;idea是真心难用,而且是好几年没更新的插件了),一种是用activiti官方提供的工具 activiti-app (6.0的版本,我们只用它来画图),把activiti-app.war放在tomcat运行。

1、绘制流程图

  • 访问地址: http://localhost :8080/activiti-app
  • 账号:admin
  • 密码:test

先创建一个流程 springboot2.0+activiti 7 整合(三)--创建自己的业务流程

springboot2.0+activiti 7 整合(三)--创建自己的业务流程

创建一个请假流程

流程图如下:

springboot2.0+activiti 7 整合(三)--创建自己的业务流程

关键属性:

  1. 每个矩形框就是一个userTask,最关键的属性:Assignments 任务指定人

因为没有使用activiti的identity(认证)部分,所有我选择动态传入一个参数进去(动态变量名不能重复): springboot2.0+activiti 7 整合(三)--创建自己的业务流程

  1. 每个连接线就是一个sequenceFlow,最关键的属性是:Flow condition 顺序流条件;可以设置条件表达式;这里分支的变量名必须一致,比如审核通过为“${audit==1”},审核不通过为${audit==1”}

2、导入流程图

将画好的流程图下载到本地,在processes目录下新建文件(leave.bpmn20.xml),将流程图用文本打开复制进xml中:

3、配置application.yml

spring:
  datasource:
    #数据源基本配置
    username: root
    password: root
    url: jdbc:mysql://localhost/activiti?serverTimezone=Asia/Shanghai&characterEncoding=UTF-8&nullCatalogMeansCurrent=true&useSSL=false&useLegacyDatetimeCode=false
    driver-class-name: com.mysql.cj.jdbc.Driver
  activiti:
    # 开启历史库
    db-history-used: true
    history-level: audit

历史信息级别可以配置成以下几种(activiti7感觉默认的是none):

none: 忽略所有历史存档。这是流程执行时性能最好的状态,但没有任何历史信息可用。

activity: 保存所有流程实例信息和活动实例信息。 在流程实例结束时, 最后一个流程实例中的最新的变量值将赋值给历史变量。 不会保存过程中的详细信息。

audit: 它保存所有流程实例信息, 活动信息, 保证所有的变量和提交的表单属性保持同步 这样所有用户交互信息都是可追溯的,可以用来审计。

full: 这个是最高级别的历史信息存档,同样也是最慢的。 这个级别存储发生在审核以及所有其它细节的信息, 主要是更新流程变量。

4、开启一个任务

/**
     * 开启一个请假流程
     * @param user 用户key
     * @param processDefinitionKey 流程图key 每一个流程有对应的一个key这个是某一个流程内固定的写在bpmn内的
     */
    void startLeaveProcess(String user,String processDefinitionKey){
        System.out.println(user+"开启一个请假流程:"+ processDefinitionKey);
        HashMap<String, Object> variables=new HashMap<>();
        variables.put("user", user);//userKey在上文的流程变量中指定了

        ProcessInstance instance = runtimeService
                .startProcessInstanceByKey(processDefinitionKey,variables);
        System.out.println("流程实例ID:"+instance.getId());
        System.out.println("流程定义ID:"+instance.getProcessDefinitionId());
        System.out.println("==================================================================");
    }

运行结果:

张三开启一个请假流程:leave
流程实例ID:34f2f038-0d07-11ea-b319-9c5c8e7034f6
流程定义ID:leave:1:32f7bc77-0d07-11ea-b319-9c5c8e7034f6
==================================================================

注意数据库的变化:

mysql> select ID_,REV_,PROC_INST_ID_,NAME_,ASSIGNEE_ from act_ru_task;
+--------------------------------------+------+--------------------------------------+----------+-----------+
| ID_                                  | REV_ | PROC_INST_ID_                        | NAME_    | ASSIGNEE_ |
+--------------------------------------+------+--------------------------------------+----------+-----------+

+--------------------------------------+------+--------------------------------------+----------+-----------+
1 row in set

5、根据执行人查询当前流程

/**
     * 查询当前任务流程
     */
    void queryLeaveProcessING(String assignee){
        System.out.println(assignee+"查询自己当前的流程:");
        List<Task> list = taskService.createTaskQuery()//创建任务查询对象
                .taskAssignee(assignee)//指定个人任务查询
                .list();
        if(list!=null && list.size()>0){
            for(Task task:list){
                System.out.println("任务ID:"+task.getId());
                System.out.println("任务名称:"+task.getName());
                System.out.println("任务的创建时间:"+task.getCreateTime());
                System.out.println("任务的办理人:"+task.getAssignee());
                System.out.println("流程实例ID:"+task.getProcessInstanceId());
                System.out.println("执行对象ID:"+task.getExecutionId());
                System.out.println("流程定义ID:"+task.getProcessDefinitionId());
                Map<String, Object> map = task.getProcessVariables();
                for (Map.Entry<String, Object> m : map.entrySet()) {
                    System.out.println("key:" + m.getKey() + " value:" + m.getValue());
                }
                for (Map.Entry<String, Object> m : task.getTaskLocalVariables().entrySet()) {
                    System.out.println("key:" + m.getKey() + " value:" + m.getValue());
                }

            }
        }
        System.out.println("==================================================================");
    }

运行结果:

张三查询自己当前的流程:
任务ID:34f8958d-0d07-11ea-b319-9c5c8e7034f6
任务名称:填写申请
任务的创建时间:Fri Nov 22 17:05:19 CST 2019
任务的办理人:张三
流程实例ID:34f2f038-0d07-11ea-b319-9c5c8e7034f6
执行对象ID:34f3b38a-0d07-11ea-b319-9c5c8e7034f6
流程定义ID:leave:1:32f7bc77-0d07-11ea-b319-9c5c8e7034f6
==================================================================

6、提交给领导审核

void completeTask(String approve,String taskId){
        System.out.println(approve+":提交自己的流程:"+taskId);
        //任务ID
        HashMap<String, Object> variables=new HashMap<>();
        variables.put("approve", approve);//userKey在上文的流程变量中指定了
        taskService.complete(taskId,variables);

        System.out.println("完成任务:任务ID:"+taskId);
        System.out.println("==================================================================");
    }

运行结果:

领导李四:提交自己的流程:34f8958d-0d07-11ea-b319-9c5c8e7034f6
完成任务:任务ID:34f8958d-0d07-11ea-b319-9c5c8e7034f6
==================================================================

数据库:

mysql> select ID_,REV_,PROC_INST_ID_,NAME_,ASSIGNEE_ from act_ru_task;
+--------------------------------------+------+--------------------------------------+----------+-----------+
| ID_                                  | REV_ | PROC_INST_ID_                        | NAME_    | ASSIGNEE_ |

+--------------------------------------+------+--------------------------------------+----------+-----------+
1 row in set

7、领导审核通过

void completeTask(String user,String taskId,int audit){
        System.out.println(user+":提交自己的流程:"+taskId+" ;是否通过:"+audit);
        //任务ID
        HashMap<String, Object> variables=new HashMap<>();
        variables.put("audit", audit);//userKey在上文的流程变量中指定了
        taskService.complete(taskId,variables);

        System.out.println("完成任务:任务ID:"+taskId);
        System.out.println("==================================================================");
    }

运行结果:

领导李四:提交自己的流程:e60702be-0d08-11ea-8a0a-9c5c8e7034f6 ;是否通过:1
完成任务:任务ID:e60702be-0d08-11ea-8a0a-9c5c8e7034f6
==================================================================

数据库:

mysql> select ID_,REV_,PROC_INST_ID_,NAME_,ASSIGNEE_ from act_ru_task;

8、查询历史数据

根据流程ID查询:

List<HistoricTaskInstance> list=historyService // 历史相关Service
                .createHistoricTaskInstanceQuery() // 创建历史活动实例查询
                .processInstanceId("34f2f038-0d07-11ea-b319-9c5c8e7034f6") // 执行流程实例id
                .orderByTaskCreateTime()
                .asc()
                .list();
        for(HistoricTaskInstance hai:list){
            System.out.println("活动ID:"+hai.getId());
            System.out.println("流程实例ID:"+hai.getProcessInstanceId());
            System.out.println("活动名称:"+hai.getName());
            System.out.println("办理人:"+hai.getAssignee());
            System.out.println("开始时间:"+hai.getStartTime());
            System.out.println("结束时间:"+hai.getEndTime());
            System.out.println("==================================================================");
        }

运行结果:

            System.out.println("流程实例ID:"+hai.getProcessInstanceId());
            System.out.println("活动名称:"+hai.getName());
            System.out.println("办理人:"+hai.getAssignee());
