maven項(xiàng)目如下：

配置好數(shù)據(jù)庫(kù)，和activiti的配置之后，開始執(zhí)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;

/**

* 通過讀取bpmn文件，來部署流程圖

*

* @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));

}

}

報(bào)錯(cuò)如下：

[main] ERROR org.activiti.engine.impl.interceptor.CommandContext - Error while closing command context

解決方法：

(1)把mysql8.0的版本改成5.0的

mysql

mysql-connector-java

5.1.41

(2)修改驅(qū)動(dòng)：
