spring boot和activiti的demo

1、添加依赖

<dependency>
	<groupId>org.activiti</groupId>
	<artifactId>activiti-spring-boot-starter-basic</artifactId>
	<version>6.0.0</version>
</dependency>

2、配置数据库信息

    mysql数据库配置

server:
  port: 8080
spring:
  application:
    name: activiti
  datasource:
    url: jdbc:mysql://xxxx.x.x.x:3306/xxxx?characterEncoding=utf8&useSSL=true
    driver-class-name: com.mysql.jdbc.Driver #配置JDBC Driver
    username: xxx
    password: xxxx
  jpa:
    hibernate:
      ddl-auto: update
    properties:
      hibernate:
        show_sql: true
        use_sql_comments: true
        format_sql: true

3、接口定义及实现

    接口ActivityService

public interface ActivityService {
	/**
	 * 工作流
	 * @return
	 */
	public boolean startActivity();

}

    实现ActivityServiceImpl

import java.util.HashMap;
import java.util.Map;

import org.activiti.engine.RuntimeService;
import org.activiti.engine.TaskService;
import org.activiti.engine.impl.persistence.entity.ExecutionEntity;
import org.activiti.engine.task.Task;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service("activityService")
public class ActivityServiceImpl implements ActivityService {
	private final Logger logger = LoggerFactory.getLogger(getClass());

	@Autowired
	private RuntimeService runtimeService;
	@Autowired
	private TaskService taskService;

	@Override
	public boolean startActivity() {
		logger.info("工作流启动....");
		Map<String, Object> map = new HashMap<String, Object>();
		map.put("apply", "zhangsan");
		map.put("approve", "lisi");
		// 流程启动
		ExecutionEntity pi1 = (ExecutionEntity) runtimeService.startProcessInstanceByKey("leave2", map);
		
		String processId = pi1.getId();
		Task task = taskService.createTaskQuery().processInstanceId(processId).singleResult();
		logger.info("task 第一步:{}", task);
		taskService.complete(task.getId(), map);// 完成第一步申请

		task = taskService.createTaskQuery().processInstanceId(processId).singleResult();
		logger.info("task 第二步:{}", task);
		String taskId2 = task.getId();
		map.put("pass", false);
		taskService.complete(taskId2, map);// 驳回申请
		
		task = taskService.createTaskQuery().processInstanceId(processId).singleResult();
		logger.info("task 第三步:{}", task);
		logger.info("工作流结束....");
		return false;
	}
}

4、创建bpmn文件

    在resources目录下新建文件夹：processes，并在processes创建一个新的bpmn文件

<?xml version="1.0" encoding="UTF-8"?>

5、测试类测试

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.spring.pro.ProviderApplication;
import com.spring.pro.service.ActivityService;

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = ProviderApplication.class)
public class ActivitiTest {

	@Resource(name = "activityService")
	private ActivityService activityService;

	@Test
	public void leaveProcess() {
		activityService.startActivity();
	}
}
