activiti 插件安装，以及初始化配置

1.安装插件

2.添加pom

3.配置activiti.cfg.xml

4.绘制业务流程图 MyProcess.bpmn

5.加载activiti数据表

6.创建流程

1.安装eclipse activiti 插件

Activiti BPMN 2.0 designer

3.配置activiti.cfg.xml

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">

	<bean id="processEngineConfiguration"
		class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">
		<property name="jdbcDriver" value="com.mysql.jdbc.Driver" />
		<property name="jdbcUrl"
			value="jdbc:mysql://localhost:3306/test?characterEncoding=utf8" />
		<property name="jdbcUsername" value="root" />
		<property name="jdbcPassword" value="centos" />
		<property name="databaseSchemaUpdate" value="true" />
	</bean>
</beans>

4.绘制业务流程图 MyProcess.bpmn

5.加载activiti数据表

6.创建流程

package activitiDemo;

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngineConfiguration;
import org.activiti.engine.repository.Deployment;
import org.junit.Test;

public class JunitTest {

	/**
	 * 加载activiti 表
	 */
	@Test
	public void installActiviti() {
		//表不存在的话创建表
		ProcessEngine processEngine = ProcessEngineConfiguration
				.createProcessEngineConfigurationFromResource("activiti.cfg.xml")
		.buildProcessEngine();

		System.out.println("------processEngine:" + processEngine);

	}

	/**
	 * 创建activiti流程
	 */
	@Test
	public void createProcess() {
		//创建流程
		ProcessEngine processEngine = ProcessEngineConfiguration
				.createProcessEngineConfigurationFromResource("activiti.cfg.xml").buildProcessEngine();
		Deployment deployment = processEngine.getRepositoryService().createDeployment().name("请假程序")
		.addClasspathResource("diagrams/MyProcess.bpmn").addClasspathResource("diagrams/MyProcess.png").deploy();

		System.out.println(deployment.getId());
		System.out.println(deployment.getName());
	}
}
