Activiti创建定义

流程表创建

创建 .bpmn 文件,画好流程图,把 .bpmn文件改名为 .xml文件,选择该文件,按下图操作

之后就能得到流程图,复制到resource文件内

获得工作流数据引擎对象
方法一.java文件直接创建

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngineConfiguration;

public class Text1 {
  //初始化数据库
  public static void main(String[] args) {
      ProcessEngineConfiguration configuration=
              ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration();
      //指定数据库的连接信息
      configuration.setJdbcUrl("jdbc:mysql://localhost:3306/bpmnl?createDatabaseIfNotExist=true");
      configuration.setJdbcDriver("com.mysql.jdbc.Driver");
      configuration.setJdbcUsername("root");
      configuration.setJdbcPassword("123");
      //设置数据表的操作模式
      configuration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
      System.out.println("数据库操作");
      //得到工作流引擎对象
      ProcessEngine pe=configuration.buildProcessEngine();
      System.out.println(pe);
  }


}

方法二
配置好activiti.cfg.xml

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngineConfiguration;

public class Text2 {
    public static void main(String[] args) {
        ProcessEngine pe=
                ProcessEngineConfiguration
                .createProcessEngineConfigurationFromResource("activiti.cfg.xml")
                .buildProcessEngine();
        System.out.println(pe);
    }
}

方法三
获得工作流数据引擎对象
注意:配置文件的名称必须是:activiti.cfg.xml

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;

public class Text3 {
    public static void main(String[] args) {
        //获得工作流数据引擎对象
        //注意:配置文件的名称必须是:activiti.cfg.xml
        ProcessEngine pe=
                ProcessEngines.getDefaultProcessEngine();
        System.out.println(pe);
    }
}

创建流程定义
方法一

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.springframework.stereotype.Repository;

public class Text4 {
    public static void main(String[] args) {
        //先得到流程引擎对象
        ProcessEngine processEngine=
                ProcessEngines.getDefaultProcessEngine();
        //得到服务对象
        RepositoryService repositoryService=processEngine.getRepositoryService();

        //创建流程定义,添加资源文件  Deployment 部署
        DeploymentBuilder builder=
        repositoryService.createDeployment()
                .addClasspathResource("a1.bpmn")
                .addClasspathResource("a1.png");
        //部署(发布流程)
        Deployment deployment=builder.deploy();

        //查询部署的id信息
        System.out.println(deployment.getId()+","+deployment.getName());
    }
}

方法二
压缩文件得到流程定义

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 java.io.InputStream;
import java.util.zip.ZipInputStream;

public class Text5 {
    public static void main(String[] args) {
        //先得到流程引擎对象
        ProcessEngine pe=
                ProcessEngines.getDefaultProcessEngine();
        //得到服务对象
        RepositoryService repositoryService=pe.getRepositoryService();

        //创建流程定义,添加资源文件
        //得到压缩文件信息
        InputStream in=
                Text5.class.getClassLoader().getResourceAsStream("a1.zip");
        ZipInputStream zipInputStream=new ZipInputStream(in);
        DeploymentBuilder builder=
                repositoryService.createDeployment()
                .addZipInputStream(zipInputStream);

        //部署
        Deployment deployment=builder.deploy();
        //查询部署id
        System.out.println(deployment.getId()+","+deployment.getName());
    }
}
