工作流activiti 6 学习笔记十五 java 应用整合spring

配置spring.xml 文件，可以随意命名

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
	<!-- 配置数据源 -->
	<bean id="dataSource" class="org.springframework.jdbc.datasource.SimpleDriverDataSource">
		<property name="url" value="jdbc:mysql://127.0.0.1:3306/myactlearn" />
	    <property name="driverClass" value="com.mysql.jdbc.Driver" />
	    <property name="username" value="root" />
	    <property name="password" value="Happy123" />
	</bean>
	
	<!-- 配置事务 -->
	<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource"></property>
	</bean>
	<!-- 配置流程引擎 -->
  <bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
	<property name="dataSource" ref="dataSource"></property>
    <property name="databaseSchemaUpdate" value="true" />
    <property name="transactionManager" ref="transactionManager"></property>
    <property name="asyncExecutorActivate" value="true" />
  </bean>
  <!-- 初始化引擎 -->
  <bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean">
  	<property name="processEngineConfiguration" ref="processEngineConfiguration"></property>
  </bean>
  
  <!-- 初始化常用的几个服务 -->
  <bean id="rs" factory-bean="processEngine" factory-method="getRepositoryService"></bean>
  <bean id="runS" factory-bean="processEngine" factory-method="getRuntimeService"></bean>
  <bean id="ts" factory-bean="processEngine" factory-method="getTaskService"></bean>

</beans>

测试类：

package org.scf.act.spring;

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.RuntimeService;
import org.activiti.engine.TaskService;
import org.activiti.engine.repository.Deployment;
import org.activiti.engine.repository.ProcessDefinition;
import org.activiti.engine.runtime.ProcessInstance;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
/**
 * 结合sping并部署一个流程
 * @author scf
 *
 */
public class SpringTest {
	public static void main(String[] args) {
		ApplicationContext ctx = new ClassPathXmlApplicationContext(new String[] {"activiti.cfg.spring.xml"}) ;
		ProcessEngine engine = (ProcessEngine)ctx.getBean("processEngine");
		
		// 存储服务
		RepositoryService rs =(RepositoryService)ctx.getBean("rs");
		// 运行时服务
		RuntimeService runS = (RuntimeService)ctx.getBean("runS");
		// 任务服务
		TaskService ts = (TaskService)ctx.getBean("ts");
		// 部署流程
		Deployment deploye = rs.createDeployment().addClasspathResource("multi.bpmn").deploy();
		ProcessDefinition  pdf = rs.createProcessDefinitionQuery().deploymentId(deploye.getId()).singleResult();
		
		ProcessInstance  pi = runS.startProcessInstanceById(pdf.getId());
		System.out.println(pi.getId());

		
	}
}

代码解释：

加载spring文件，从spring文件中获取bean，根据spring factroy bean 和method 获取服务对象。

注：

也可以在spring配置文件中直接部署流程文件

代码如下：

<!-- 配置流程引擎 -->
  <bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
	<property name="dataSource" ref="dataSource"></property>
    <property name="databaseSchemaUpdate" value="true" />
    <property name="transactionManager" ref="transactionManager"></property>
    <property name="asyncExecutorActivate" value="true" />
    <property name="deploymentResources">
    	<list>
    		<value>leave.bpmn</value>
    	</list>
    </property>
  </bean>
