1.idea安装actibpm流程设计器
打开idea插件搜索actibpm,安装成功后重启idea
2.创建maven项目,导入相关依赖,添加配置文件
pom.xml依赖

配置文件
#启动端口
server.port=81
spring.datasource.url=jdbc:mysql://localhost:3306/acttest?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT%2B8&nullCatalogMeansCurrent=true
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
#1.false,默认值,acticiti启动时对比数据库表中保存的版本,如果没有表或者版本不匹配,将抛出异常
#2.true,acticiti会对数据中所有的表进行更新操作,如果表不存在,则自动创建
#3.create_drop,在acticiti启动时创建表,关闭时删除表(必须手动关闭引擎才能删除表)
#4.drop_create,在acticiti启动时删除原来的表,然后创建新表(不需要手动关闭引擎)
spring.activiti.database-schema-update=true
#检测历史表是否存在,acticit7默认没有开启历史记录信息
spring.activiti.db-history-used=true
#历史记录等级
#1.none:不保存任何历史记录,因此在流程执行过程中,这是最高效的
#2.acticiti:级别高于none,保存流程实例与流程行为,其他数据不保存
#3.audit:除activiti级别会保存的数据外,还会保存全部的流程任务及其属性,audit为默认值
#4.full:保存历史数据的最高级别,除了保存audit级别的数据外,还会保存其他流程相关的细节数据,包括一些流程参数等
spring.activiti.history-level=full
#默认true,效验流程文件,默认效验resources下的processes文件夹里的流程,为true自动部署流程,为false则不部署
#spring.activiti.check-process-definitions=false
3.新增启动类,剔除掉activiti默认集成springsecurity
package com.dongmen;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication(exclude = {
org.activiti.spring.boot.SecurityAutoConfiguration.class,
org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration.class})
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}
4.新建文件夹processes(名称不能更改),新增Bpmn文件,画流程图
这里我们用到了三种标签,
连接下一个标签的线条,需要鼠标移动到标签中间来获取线条
画好流程图后点击空白处,左边会出现流程参数,这里我们只需要设置流程的id与name即可
设置审批用户信息,这里我第一个节点设置的时zhangsan,第二个节点设置的是lisi,设置成功后保存
左侧菜单介绍
5.创建Controller
package com.dongmen.controller;
import org.activiti.engine.HistoryService;
import org.activiti.engine.RuntimeService;
import org.activiti.engine.TaskService;
import org.activiti.engine.history.HistoricTaskInstance;
import org.activiti.engine.runtime.ProcessInstance;
import org.activiti.engine.task.Task;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.List;
@RestController
public class TestController {
@Autowired
private RuntimeService runtimeService;
@Autowired
private TaskService taskService;
@Autowired
private HistoryService historyService;
//启动流程
@RequestMapping("/startAct")
public void startAct() {
ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("myProcess_1");
System.out.println(processInstance.getId());
}
//查询代办任务
@RequestMapping("taskAgents")
public void taskAgents(){
String user="zhangsan";
List<Task> list = taskService.createTaskQuery().taskAssignee(user).list();
for (Task task : list) {
System.out.println("任务id:"+task.getId());
System.out.println("当前审批用户:"+task.getAssignee());
System.out.println("任务名称:"+task.getName());
}
}
//审批流程
@RequestMapping("/approvalProcess")
public void approvalProcess() {
String key = "myProcess_1";
String user="zhangsan";
//流程实例id,有多个流程时传递,单个不需要传,act_ru_task表id
String id="2505";
//根据流程key,与用户名称查询审批
Task task = taskService.createTaskQuery()
.processDefinitionKey(key)
.taskAssignee(user)
.taskId(id)
.singleResult();
if(task!=null){
//审批流程
taskService.complete(task.getId());
System.out.println("审批成功!");
}
}
//查询已办任务
@RequestMapping("/hasToDoTasks")
public void hasToDoTasks(){
String user="zhangsan";
List<HistoricTaskInstance> list = historyService.createHistoricTaskInstanceQuery().taskAssignee(user).list();
for (HistoricTaskInstance historicTaskInstance : list) {
System.out.println("开始时间"+historicTaskInstance.getStartTime()+",结束时间:"+historicTaskInstance.getEndTime());
System.out.println("流程名称"+historicTaskInstance.getName());
}
}
}
6.启动项目,Activiti会自动创建28张表,自动部署processes目录Bpnm文件
表结构介绍
7.测试Controller
localhost:81/startAct–启动流程,查看数据表act_ru_task
localhost:81/taskAgents–查询待办任务,访问后查看后台打印
localhost:81/approvalProcess–审批流程,点击审批流程后变成第二个节点审批
localhost:81/hasToDoTasks–查询已办任务,
