**一 代码**

package com.syc.activiti;
    
    import org.activiti.engine.ProcessEngine;
    import org.activiti.engine.ProcessEngines;
    import org.activiti.engine.RepositoryService;
    import org.activiti.engine.repository.DeploymentBuilder;
    
    public class ProcessDeploy {
    
    
        public static void main( String[] args ) {
            //创建流程引擎
            ProcessEngine engine = ProcessEngines.getDefaultProcessEngine();
            //得到流程存储服务对象
            RepositoryService repositoryService = engine.getRepositoryService();
            //创建DeploymentBuilder实例
            DeploymentBuilder builder = repositoryService.createDeployment();
            builder.addClasspathResource("bpmn/processDeploy.bpmn").deploy();
        }
    }

**二 流程文件**

**三 运行后数据库**

1 act\_re\_deployment

2 act\_re\_procdef

3 act\_ge\_bytearray
