jfinal集成activiti5.19

1、搭建好jfinal工程项目，或者直接从jfinal官网下载最新版本demo

2、导入activiti-5.19相关架包（spring相关架包除外）

3、将activiti引擎写成jfinal插件的形式

1. 建立插件类ActivitiPlugins实现IPlugin接口

2. 实现相关方法

  代码以下：

import org.activiti.engine.ProcessEngine;

import org.activiti.engine.ProcessEngineConfiguration;

import org.activiti.engine.ProcessEngines;

import com.jfinal.plugin.IPlugin;

import com.jfinal.plugin.activerecord.IDataSourceProvider;

public class ActivitiPlugins implements IPlugin {

@Override

public boolean start() {

// TODO Auto-generated method stub

if (isStarted) {

return true;

}

processEngineConfiguration = ProcessEngineConfiguration

.createStandaloneProcessEngineConfiguration()

.setDatabaseType("mysql")

.setDataSource(this.dataSourceProvider.getDataSource())

.setTransactionsExternallyManaged(true) // 使用托管事务工厂

.setDatabaseSchemaUpdate(

ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);// 数据库中没有表则建立表

// .buildProcessEngine();//开启流程引擎

// processEngine.getRepositoryService();

// configuration

System.out.println("流程引擎111:" + buildProcessEngine());

// System.out.println("流程部署服务："+processEngine.getRepositoryService());

isStarted = true;

// ProcessEngines.init();//开启流程引擎

System.out.println("启动流程引擎.......");

return isStarted;

}

@Override

public boolean stop() {

// TODO Auto-generated method stub

ProcessEngines.destroy();// 关闭流程引擎

isStarted = false;

return true;

}

// 开启流程服务引擎

public static ProcessEngine buildProcessEngine() {

if (processEngine == null)

if (processEngineConfiguration != null) {

processEngine = processEngineConfiguration.buildProcessEngine();

}

return processEngine;

}

private static ProcessEngine processEngine = null;

private static ProcessEngineConfiguration processEngineConfiguration = null;

// 基本属性 url、user、password

private IDataSourceProvider dataSourceProvider = null;

private boolean isStarted = false;

public ActivitiPlugins(IDataSourceProvider dataSourceProvider) {

this.dataSourceProvider = dataSourceProvider;

}

// get/set方法

public IDataSourceProvider getDataSourceProvider() {

return dataSourceProvider;

}

public void setDataSourceProvider(IDataSourceProvider dataSourceProvider) {

this.dataSourceProvider = dataSourceProvider;

}

}

4、将编写的插件放到jfinal插件集中运行

代码以下：

/**

* 自定义插件

*/

@Override

protected void plugin(Plugins plugins) {

// 添加数据源

Prop p = PropKit.use("default/jdbc.config");

final String url = PropKit.get("activiti_url");

final String username = PropKit.get("activiti_user");

final String password = PropKit.get("activiti_pwd");

DruidPlugin druidPlugin = new DruidPlugin(url, username, password);

plugins.add(druidPlugin);

        //activiti 配置

        ActivitiPlugins activitiPlugins = new ActivitiPlugins(druidPlugin);   

        plugins.add(activitiPlugins);

}

5、到此便可运行项目
