这篇文章将为大家详细讲解有关SpringBoot1.5.9如何集成Activiti6，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。
1.通过以下地址创建基于Maven的SpringBoot Web项目
https://start.spring.io/
2.添加项目的依赖文件
pom.xml文件如下
<?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"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>activiti.demo</groupId>
<artifactId>activiti-demo</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>war</packaging>

</plugins>
</build>
</project>
3.添加业务流程文件
在src/main/java/resource目录下创建processes目录
创建process.bpmn文件，内容如下
<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:activiti="http://activiti.org/bpmn" xmlns:bpmndi="http://www.omg.org/spec/BPMN/20100524/DI" xmlns:omgdc="http://www.omg.org/spec/DD/20100524/DC" xmlns:omgdi="http://www.omg.org/spec/DD/20100524/DI" xmlns:dc="http://www.omg.org/spec/DD/20100524/DC" xmlns:di="http://www.omg.org/spec/DD/20100524/DI" typeLanguage="http://www.w3.org/2001/XMLSchema" expressionLanguage="http://www.w3.org/1999/XPath" targetNamespace="http://www.activiti.org/testm1510735932336" id="m1510735932336" name="">

</sequenceFlow>
<sequenceFlow id="_13" sourceRef="modify" targetRef="approve"></sequenceFlow>
</process>

</bpmndi:BPMNEdge>
</bpmndi:BPMNPlane>
</bpmndi:BPMNDiagram>
</definitions>
4.配置application.properties文件
配置内容如下
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/activiti?useSSL=false&serverTimezone=UTC&useLegacyDatetimeCode=false&autoReconnect=true&failOverReadOnly=false&useUnicode=true&characterEncoding=UTF-8
spring.datasource.username=root
spring.datasource.password=123456
spring.jpa.properties.hibernate.hbm2ddl.auto=update
spring.jpa.show-sql=true
server.port=8082
server.context-path=/
server.session.timeout=10
server.tomcat.uri-encoding=UTF-8
5.代码实现
a.定义接口
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("/activityConsumerService")
public interface ActivityConsumerService {
@RequestMapping(value = "/startActivityDemo",method = RequestMethod.GET)
public boolean startActivityDemo();
}
b.实现接口
package com.springboot.demo.service.impl;
import com.springboot.demo.service.ActivityConsumerService;
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.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
/**
* @ClassName ActivityConsumerServiceImpl
* @Description TODO
* @Author yunshuodeng
* @Date 2019-04-29 13:28
* @Version 1.0
**/
@Service("activityService")
public class ActivityConsumerServiceImpl implements ActivityConsumerService {
@Autowired
private RuntimeService runtimeService;
@Autowired
private TaskService taskService;
@Autowired
private RepositoryService repositoryService;
@Override
public boolean startActivityDemo() {
// 获取当前方法名
String methodName = Thread.currentThread().getStackTrace()[1].getMethodName();
// 定义任务办理人
String name1 = "zhangsan";
String name2 = "lisi";
System.out.println("method " + methodName + " begin ...");
// 输出流程部署数量
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<>();
map.put("apply",name1);
map.put("approve",name2);
// 流程启动
ExecutionEntity executionEntity = (ExecutionEntity) runtimeService.startProcessInstanceByKey("leave",map);
// 查询name1的任务列表
List<Task> taskList = taskService.createTaskQuery().taskAssignee(name1).list();
// 输出任务数量
System.out.println(taskList.size());
if (taskList != null && taskList.size() > 0){
for (Task task : taskList){
System.out.println("任务ID："+task.getId());
System.out.println("任务办理人："+task.getAssignee());
System.out.println("任务名称："+task.getName());
System.out.println("任务创建时间："+task.getCreateTime());
System.out.println("流程实例ID："+task.getProcessDefinitionId());
System.out.println("-------------------------------------------");
}
}
System.out.println("method " + methodName + " end ...");
return false;
}
}
6.启动服务并通过以下地址进行访问
http://localhost:8082/activityConsumerService/startActivityDemo
7.查看控制台输出内容并不报错表示已整合完成
