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

2.安裝好bpmn插件后開(kāi)始新建bpmn文件，也就是畫(huà)流程圖

一般是在代碼中進(jìn)行指定流程審批人的，我這里只做入門(mén)案例

3.添加pom依賴

這里包含了在線設(shè)計(jì)流程圖的相關(guān)依賴，在下一篇會(huì)寫(xiě)出來(lái)，項(xiàng)目中一般都是在前端在線設(shè)計(jì)；所以直接放上去也沒(méi)事

4.yml文件

這里采用的數(shù)據(jù)庫(kù)還是mysql

這里有個(gè)需要注意的地方，springboot2.2中的driver-class-name值變了，不是以前的那個(gè)了，不然會(huì)報(bào)錯(cuò)

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(dòng)部署驗(yàn)證設(shè)置:true-開(kāi)啟（默認(rèn)）、false-關(guān)閉check-process-definitions: false#自動(dòng)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(jīng)好了，下面開(kāi)始寫(xiě)代碼了，只是初步寫(xiě)了一些新建流程，正常提交流程，直接結(jié)束流程，以及查詢待辦的案例，細(xì)節(jié)還需要各自自己去調(diào)試學(xué)習(xí)

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(cè)流程 * @return */ @RequestMapping('/createDeployment') public Boolean createDeployment(){ return activityConsumerService.createDeployment(); } /** * 啟動(dòng)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(jù)流程id直接結(jié)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(shí)現(xiàn)類(lèi)

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(cè)一個(gè)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(jù)流程key開(kāi)啟一個(gè)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(jù)任務(wù)id提交任務(wù) * @param taskId * @return */ @Override public boolean complete(String taskId){ taskService.complete(taskId); return true; } /** * 根據(jù)流程id直接結(jié)束流程 * @param runId * @return */ @Override public boolean deleteProcessInstance(String runId){ runtimeService.deleteProcessInstance(runId,'結(jié)束'); return true; }}

啟動(dòng)類(lèi)，這里存在一個(gè)在線視圖設(shè)計(jì)的驗(yàn)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(jīng)寫(xiě)好了

備注說(shuō)明：

項(xiàng)目啟動(dòng)會(huì)新建28張表，各自代表的含義自行百度把

因?yàn)槲业臄?shù)據(jù)都是直接在流程圖bpmn文件里面寫(xiě)好的，實(shí)際中肯定是在代碼里面指定的

首先訪問(wèn)注冊(cè)流程

啟動(dòng)流程（會(huì)返回一個(gè)流程id）

查看待辦就可以獲取相關(guān)的信息了

正常提交任務(wù)，會(huì)審批到下一節(jié)點(diǎn)（查看待辦可以得到任務(wù)id）

直接結(jié)束流程（非正常結(jié)束，啟動(dòng)流程的id傳入即可）

請(qǐng)求案例

查詢待辦

啟動(dòng)流程

以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持好吧啦網(wǎng)。
