一.前言

      前面Activiti工作流的学习,说明了Activiti的基本应用,在我们开发中可以根据实际的业务参考Activiti的API去更好的理解以及巩固。我们实际的开发中我们基本上都使用spring框架进行开发,现在来说明一下Activiti工作流与spring集成,Activiti工作流与spring集成还算比较简单,可以参考Activiti的API来进行整合。

二.Activiti常用的表

---------------------------------------------部署对象和流程定义相关的表---------------------------------------------

--部署对象信息表 
SELECT T.*, T.ROWID FROM ACT_RE_DEPLOYMENT T;

--流程定义表 
--ID_ 由KEY_ + VERSION_ + 随机生成是数组成
SELECT T.*, T.ROWID FROM ACT_RE_PROCDEF T where t.category_=‘1‘ order by t.version_ asc;

--资源文件表
SELECT T.*, T.ROWID FROM ACT_GE_BYTEARRAY T;

--主键生成策略表
SELECT T.*, T.ROWID FROM ACT_GE_PROPERTY T;

------------------------------------------流程实例、执行对象、任务------------------------------------------------

--正在执行的执行对象表

三.Activiti与spring整合xml配置文件

向spring配置文件中,添加一个spring-workflow2-activiti.xml配置文件,里面如下:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

    http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-2.5.xsd">

    <!--工作流引擎配置 -->
    <bean id="processEngineConfiguration" class="com.shine.workflow2.spring.ShineSpringProcessEngineConfiguration">
        <property name="dataSource" ref="dataSource" />
        <property name="transactionManager" ref="transactionManager" />
        <property name="databaseSchemaUpdate" value="false" />
        <property name="jobExecutorActivate" value="false" />
         <!-- 组织机构适配  -->
        <property name="organizationConnector"  ref="organizationAdapter" />

     </bean>
     
      <!-- 组织机构适配实现  -->
     <bean id="organizationAdapter" class="com.shine.workflow2.organization.impl.OrganizationAdapter" />

    <!--工作流引擎 -->
    <bean id="processEngine" class="com.shine.workflow2.spring.ShineProcessEngineFactoryBean"> 
        <property name="processEngineConfiguration" ref="processEngineConfiguration" />
    </bean>
    
    
    <!--扩展服务 -->
    <bean id="processDefinitionService" factory-bean="processEngine"
        factory-method="getProcessDefinitionService" />
    <bean id="processLogService" factory-bean="processEngine"
        factory-method="getProcessLogService" />
    <bean id="processManagementService" factory-bean="processEngine"
        factory-method="getProcessManagementService" />
    
    <!--原生服务 -->
    <bean id="repositoryService" factory-bean="processEngine"
        factory-method="getRepositoryService" />
    <bean id="runtimeService" factory-bean="processEngine"
        factory-method="getRuntimeService" />
    <bean id="taskService" factory-bean="processEngine"

    <bean id="managementService" factory-bean="processEngine"
        factory-method="getManagementService" />
    <bean id="formService" factory-bean="processEngine"
        factory-method="getFormService" />
    <bean id="identityService" factory-bean="processEngine"
        factory-method="getIdentityService" />
    
</beans>
