1.第一步添加bpmn文件得插件，不然没法查看和编辑bpmn文件，添加插件的方法各自百度即可，很简单

2.安装好bpmn插件后开始新建bpmn文件，也就是画流程图

Springboot集成activity的用法

一般是在代码中进行指定流程审批人的，我这里只做入门案例

3.添加pom依赖

这里包含了在线设计流程图的相关依赖，在下一篇会写出来，项目中一般都是在前端在线设计；所以直接放上去也没事

4.yml文件

这里采用的数据库还是mysql

这里有个需要注意的地方，springboot2.2中的driver-class-name值变了，不是以前的那个了，不然会报错

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:
# 自动部署验证设置:true-开启（默认）、false-关闭
check-process-definitions: false
#自动部署文件路径后缀
# process-definition-location-prefix: classpath:/processes/
# process-definition-location-suffixes:
# - **.bpmn
# - **.bpmn20.xml
server:
port: 8082

5.配置已经好了，下面开始写代码了，只是初步写了一些新建流程，正常提交流程，直接结束流程，以及查询待办的案例，细节还需要各自自己去调试学习

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;

  /**
   * 注册流程
   * @return
   */
  @RequestMapping("/createDeployment")
  public Boolean createDeployment(){
    return activityConsumerService.createDeployment();
  }

  /**
   * 启动流程
   * @return
   */
  @RequestMapping("/startActivityDemo")
  public Boolean startActivityDemo(){
    return activityConsumerService.startActivityDemo("test01");
  }

  /**
   * 获取待办
   * @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);
  }
  /**
   * 根据流程id直接结束流程
   * @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);
}

实现类

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;

  /**
   * 注册一个流程
   * @return
   */
  @Override
  public boolean createDeployment() {
    DeploymentBuilder builder=repositoryService.createDeployment();
    builder.addClasspathResource("test01.bpmn");
    builder.deploy();
    return true;
  }

  /**
   * 查询待办
   * @return
   */
  public boolean getTaskList(){
    //获取待办的一些信息，这里可以传入需要查询的用户，
    //我这里查询的所有待办
    List 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;
  }


  /**
   * 根据流程key开启一个流程
   * @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;
  }

  /**
   * 根据任务id提交任务
   * @param taskId
   * @return
   */
  @Override
  public boolean complete(String taskId){
    taskService.complete(taskId);
    return true;
  }

  /**
   * 根据流程id直接结束流程
   * @param runId
   * @return
   */
  @Override
  public boolean deleteProcessInstance(String runId){
    runtimeService.deleteProcessInstance(runId,"结束");
    return true;
  }
}

启动类，这里存在一个在线视图设计的验证处理，

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);
  }
}

所有的代码已经写好了

备注说明：

项目启动会新建28张表，各自代表的含义自行百度把

因为我的数据都是直接在流程图bpmn文件里面写好的，实际中肯定是在代码里面指定的

首先访问注册流程

启动流程（会返回一个流程id）

查看待办就可以获取相关的信息了

正常提交任务，会审批到下一节点（查看待办可以得到任务id）

直接结束流程（非正常结束，启动流程的id传入即可）

请求案例

查询待办
