maven项目如下：
配置好数据库，和activiti的配置之后，开始执行流程部署
package com.yuanqiao.first_activiti.deployment;
import java.util.List;
import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.repository.Deployment;
import org.activiti.engine.repository.DeploymentBuilder;
import org.activiti.engine.repository.ProcessDefinition;
import org.junit.Test;
import com.google.gson.Gson;
/**
* 通过读取bpmn文件，来部署流程图
*
* @author yuanqiao

*/
public class DeploymentProcess {
@Test
public void deploymentFirstProcess() {
ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
RepositoryService repositoryService = processEngine.getRepositoryService();
DeploymentBuilder deploymentBuilder = repositoryService.createDeployment().addClasspathResource("first.bpmn");
Deployment deployment = deploymentBuilder.deploy();
String deploymentId = deployment.getId();
System.out.println(deploymentId);
List processDefinitionList = repositoryService.createProcessDefinitionQuery()
.deploymentId(deploymentId).list();
Gson gson = new Gson();
System.out.println(gson.toJson(processDefinitionList));
}
}
报错如下：

解决方法：
(1)把mysql8.0的版本改成5.0的
mysql
mysql-connector-java
5.1.41
(2)修改驱动：
