1.第一步添加bpmn文件得插件，不然沒法查看和編輯bpmn文件，添加插件的方法各自百度即可，很簡單

2.安裝好bpmn插件后開始新建bpmn文件，也就是畫流程圖

一般是在代碼中進行指定流程審批人的，我這里只做入門案例

3.添加pom依賴

這里包含了在線設計流程圖的相關依賴，在下一篇會寫出來，項目中一般都是在前端在線設計；所以直接放上去也沒事

4.yml文件

這里采用的數據庫還是mysql

這里有個需要注意的地方，springboot2.2中的driver-class-name值變了，不是以前的那個了，不然會報錯

spring:datasource:url: jdbc:mysql://localhost:3307/t2?useUnicode=true&characterEncoding=utf-8&useSSL=false&autoReconnect=true&serverTimezone=UTCusername: rootpassword: rootdriver-class-name: com.mysql.cj.jdbc.Driveractiviti:# 自動部署驗證設置:true-開啟（默認）、false-關閉check-process-definitions: false#自動部署文件路徑后綴# process-definition-location-prefix: classpath:/processes/# process-definition-location-suffixes:# - **.bpmn# - **.bpmn20.xmlserver:port: 8082

5.配置已經好了，下面開始寫代碼了，只是初步寫了一些新建流程，正常提交流程，直接結束流程，以及查詢待辦的案例，細節還需要各自自己去調試學習

controller

package com.springboot_activiti.controller;import com.springboot_activiti.service.ActivityConsumerService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;@RestController@RequestMapping('/activiti')public class ActivitiController { @Autowired private ActivityConsumerService activityConsumerService; /** * 注冊流程 * @return */ @RequestMapping('/createDeployment') public Boolean createDeployment(){ return activityConsumerService.createDeployment(); } /** * 啟動流程 * @return */ @RequestMapping('/startActivityDemo') public Boolean startActivityDemo(){ return activityConsumerService.startActivityDemo('test01'); } /** * 獲取待辦 * @return */ @RequestMapping('/getTaskList') public boolean getTaskList(){ return activityConsumerService.getTaskList(); } /** * 提交 * @param taskId * @return */ @RequestMapping('/complete') public boolean complete(String taskId){ return activityConsumerService.complete(taskId); } /** * 根據流程id直接結束流程 * @paramru * @return */ @RequestMapping('/deleteProcessInstance') public boolean deleteProcessInstance(String runId){ return activityConsumerService.deleteProcessInstance(runId); }}

service

package com.springboot_activiti.service;public interface ActivityConsumerService { boolean createDeployment(); boolean startActivityDemo(String key); boolean getTaskList(); boolean complete(String taskId); boolean deleteProcessInstance(String runId);}

實現類

package com.springboot_activiti.service;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.runtime.ProcessInstance;import org.activiti.engine.task.Task;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import java.util.List;@Service('activityService')public class ActivityConsumerServiceImpl implements ActivityConsumerService { @Autowired private RuntimeService runtimeService; @Autowired private TaskService taskService; @Autowired private RepositoryService repositoryService; /** * 注冊一個流程 * @return */ @Override public boolean createDeployment() { DeploymentBuilder builder=repositoryService.createDeployment(); builder.addClasspathResource('test01.bpmn'); builder.deploy(); return true; } /** * 查詢待辦 * @return */ public boolean getTaskList(){ //獲取待辦的一些信息，這里可以傳入需要查詢的用戶， //我這里查詢的所有待辦 List<Task> tasks = taskService.createTaskQuery().list(); for (Task t:tasks) { System.out.println(t.getCreateTime()); System.out.println(t.getId()); System.out.println(t.getName()); System.out.println(t.getProcessInstanceId()); System.out.println(t.getTaskDefinitionKey()); System.out.println(t.getParentTaskId()); } return true; } /** * 根據流程key開啟一個流程 * @param key * @return */ @Override public boolean startActivityDemo(String key) { ProcessInstance test01 = runtimeService.startProcessInstanceByKey(key); String id = test01.getId(); System.out.println('流程id='+id); /* */ /* String assignee = 'abc';*/ return true; } /** * 根據任務id提交任務 * @param taskId * @return */ @Override public boolean complete(String taskId){ taskService.complete(taskId); return true; } /** * 根據流程id直接結束流程 * @param runId * @return */ @Override public boolean deleteProcessInstance(String runId){ runtimeService.deleteProcessInstance(runId,'結束'); return true; }}

啟動類，這里存在一個在線視圖設計的驗證處理，

package com.springboot_activiti;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.context.annotation.ComponentScan;@ComponentScan('com')@SpringBootApplication@EnableAutoConfiguration(exclude = {org.activiti.spring.boot.SecurityAutoConfiguration.class })public class SpringbootActivitiApplication { public static void main(String[] args) { SpringApplication.run(SpringbootActivitiApplication.class, args); }}

所有的代碼已經寫好了

備注說明：

項目啟動會新建28張表，各自代表的含義自行百度把

因為我的數據都是直接在流程圖bpmn文件里面寫好的，實際中肯定是在代碼里面指定的

首先訪問注冊流程

啟動流程（會返回一個流程id）

查看待辦就可以獲取相關的信息了

正常提交任務，會審批到下一節點（查看待辦可以得到任務id）

直接結束流程（非正常結束，啟動流程的id傳入即可）

請求案例

查詢待辦

啟動流程
