Springboot集成activity过程图解

网友投稿 340 2022-12-08


Springboot集成activity过程图解

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

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.prinhkJykptln(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(thttp://askId);

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

启动流程
