第一步在项目pom.xml文件中添加所需依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</project>

第二步：编写示例接口和接口实现类

接口类（ActivityConsumerService.java）

package com.springboot.demo.service;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping( "/test")
public interface ActivityConsumerService {
/**
* 流程demo
* @return
*/
@RequestMapping(value= "/activitiDemo",method=RequestMethod.GET)
public boolean startActivityDemo();
}

接口实现类（ActivityConsumerServiceImpl.java）

package com.springboot.demo.service.impl;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import org.activiti.engine.RepositoryService;
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.activiti.engine.task.TaskQuery;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.springboot.demo.service.ActivityConsumerService;
@Service( "activityService")
public class ActivityConsumerServiceImpl implements ActivityConsumerService {
@Autowired
private RuntimeService runtimeService;
@Autowired
private TaskService taskService;
@Autowired
private RepositoryService repositoryService;
@Override
public boolean startActivityDemo() {
System.out.println( "method startActivityDemo begin....");
System.out.println( "调用流程存储服务，查询部署数量："
+ repositoryService.createDeploymentQuery().count());
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( "leave",map);
List<Task> tq=taskService.createTaskQuery().taskAssignee( "zhangsan").list();
System.out.println(tq.size());
String assignee = "zhangsan"; //当前任务办理人
List<Task> tasks = taskService //与任务相关的Service
.createTaskQuery() //创建一个任务查询对象
.taskAssignee(assignee)
.list();
if(tasks != null && tasks.size()> 0){
for(Task task:tasks){
System.out.println( "任务ID:"+task.getId());
System.out.println( "任务的办理人:"+task.getAssignee());
System.out.println( "任务名称:"+task.getName());
System.out.println( "任务的创建时间:"+task.getCreateTime());
System.out.println( "流程实例ID:"+task.getProcessInstanceId());
System.out.println( "#####################################");
}
}
System.out.println( "method startActivityDemo end....");
return false;
}
}

第三步：在src/main/java/resources目录下新建processes目录，并在该目录下新增一个业务流程文件

MyProcess.bpmn：

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

第四步：在mysql数据库服务器增加数据库：activiti-demo

第五步：设置application.properties配置自己应用的相关信息

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/activiti-demo?characterEncoding=utf8&useSSL=true
spring.datasource.username=root
spring.datasource.password=ROOT
spring.jpa.properties.hibernate.hbm2ddl.auto=update
spring.jpa.show-sql=true
server.port=8081
server.context-path=/
server.session.timeout=10
server.tomcat.uri-encoding=UTF-8

第六步：启动应用后，在浏览器地址栏输入访问地址：

http://localhost:8081/test/activitiDemo

第七步：看控制后台输出结果如下图，即代表成功。
