springboot内部实现activiti工作流框架主导的业务

#spring-boot-activiti 说明:只是一个演示项目.

}

3. 流程的执行过程

package com.patrick.example.controller;


import ActivitiService;
import org.activiti.engine.task.Task;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.ArrayList;
import java.util.List;  

@RestController
public class MyRestController {
	@Autowired
	private ActivitiService myService;
	
	//开启流程实例
	@RequestMapping(value = "/process/{personId}/{compId}", method = RequestMethod.GET)
	public void startProcessInstance(@PathVariable Long personId, @PathVariable Long compId) {
		myService.startProcess(personId, compId);
	}
	
	//获取当前人的任务
	@RequestMapping(value = "/tasks", method = RequestMethod.GET)
	public List<TaskRepresentation> getTasks(@RequestParam String assignee) {
		List<Task> tasks = myService.getTasks(assignee);
		List<TaskRepresentation> dtos = new ArrayList<TaskRepresentation>();
		for (Task task : tasks) {
			dtos.add(new TaskRepresentation(task.getId(), task.getName()));
		}
		return dtos;
	}
	
	//完成任务
	@RequestMapping(value = "/complete/{joinApproved}/{taskId}", method = RequestMethod.GET)
	public String complete(@PathVariable Boolean joinApproved, @PathVariable String taskId) {
		myService.completeTasks(joinApproved, taskId);
		return "ok";
	}
	
	//Task的dto
	static class TaskRepresentation
	
	{
		private String id;
		private String name;
		
		public TaskRepresentation(String id, String name) {
			this.id = id;
			this.name = name;
		}
		
		public String getId() {
			return id;
		}
		
		public void setId(String id) {
			this.id = id;
		}
		
		public String getName() {
			return name;
		}
		
		public void setName(String name) {
			this.name = name;
		}
	}
}

4. 流程的执行过程

要加入的公司id为1，申请加入的人的id为2:访问

http://localhost:8080/process/2/1

查看数据库表(ACT_RU_TASK ACT_RU_IDENTITYLINK)的变化

http://localhost:8080/tasks?assignee=admin 查看admin用户的任务

访问http://localhost:8080/complete/true/10 完成任务，true为同意(可以选择false)

springboot-activiti's Issues

项目默认启动不起来

项目down下来启动不起来
追加了一个配置正常了
<dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-validator</artifactId> <version>4.2.0.Final</version> </dependency>
但是访问就弹窗，这个账户密码不知道是什么呢

demo需要密码

我按照示例 需要密码？请问多少啊

访问localhost 登录密码是什么啊 一直弹出来
