Springboot集成activity過程圖解

更新時間：2020年04月29日 14:31:29 作者：網(wǎng)商紅

這篇文章主要介紹了Springboot集成activity過程圖解,文中通過示例代碼介紹的非常詳細(xì)，對大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價值,需要的朋友可以參考下

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(jìn)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(shè)計流程圖的相關(guān)依賴，在下一篇會寫出來，項目中一般都是在前端在線設(shè)計；所以直接放上去也沒事

4.yml文件

這里采用的數(shù)據(jù)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=UTC
username: root
password: root
driver-class-name: com.mysql.cj.jdbc.Driver
activiti:
# 自動部署驗證設(shè)置:true-開啟（默認(rèn)）、false-關(guān)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.xml
server:
port: 8082

5.配置已經(jīng)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(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(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);
}

實現(xiàn)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(jù)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(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;
  }
}

啟動類，這里存在一個在線視圖設(shè)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(jīng)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(shù)據(jù)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(guān)的信息了

正常提交任務(wù)，會審批到下一節(jié)點（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，啟動流程的id傳入即可）

請求案例

查詢待辦
