篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Activiti工作流学习Activiti工作流与spring集成相关的知识，希望对你有一定的参考价值。
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 -- 执行ID_ 56 流程实例ID_ 56 流程定义ID_ _3701622B-4133-7B3D-F50F-E14B4F21E847:1:55 正在运行的任务定义ID_ 【可变】 USERTASKE736BEF8-4133-7B3D-F510-7B2DE7BEA8C6 SELECT T.*, T.ROWID FROM ACT_RU_EXECUTION T; --流程实例历史表 开始信息 --历史流程定义ID_ 56 流程S实例ID_ 56 业务KEY_10000001 流程定义ID_ _3701622B-4133-7B3D-F50F-E14B4F21E847:1:55 开始任务节点ID_ STARTEVENT52B3145F-C133-7B3D-F50F-E6D48BA60EAE SELECT T.*, T.ROWID FROM ACT_HI_PROCINST T; --正在执行的任务对象表 --任务ID_ 68 执行ID_ 56 流程实例ID_ 56 流程定义ID_ _3701622B-4133-7B3D-F50F-E14B4F21E847:1:55 任务节点ID_ USERTASKE736BEF8-4133-7B3D-F510-7B2DE7BEA8C6 SELECT T.*, T.ROWID FROM ACT_RU_TASK T; --历史任务流程实例信息 --历史任务ID_ 68 流程实例ID_ 56 执行实例ID_ 56 流程定义ID_ _3701622B-4133-7B3D-F50F-E14B4F21E847:1:55 任务节点ID_ USERTASKE736BEF8-4133-7B3D-F510-7B2DE7BEA8C6 表单KEY_ /PAGES/HOLIDAY/HOLIDAYMANAGE/HOLIDAYFORMHANDLE.JSP --历史任务ID_ 74 流程实例ID_ 56 执行实例ID_ 56 流程定义ID_ _3701622B-4133-7B3D-F50F-E14B4F21E847:1:55 任务节点ID_ USERTASK04A84BE1-1133-7B3D-F511-1D0B7BB0A668 表单KEY_ /PAGES/HOLIDAY/HOLIDAYMANAGE/HOLIDAYFORMVIEW.JSP SELECT T.*, T.ROWID FROM ACT_HI_TASKINST T; --所有活动节点历史任务表 --历史任务ID_58 流程定义ID_ _3701622B-4133-7B3D-F50F-E14B4F21E847:1:55 流程实例ID_ 56 流程执行ID_ 56 任务节点ID_ STARTEVENT52B3145F-C133-7B3D-F50F-E6D48BA60EAE --历史任务ID_67 流程定义ID_ _3701622B-4133-7B3D-F50F-E14B4F21E847:1:55 流程实例ID_ 56 流程执行ID_ 56 任务节点ID_ USERTASKE736BEF8-4133-7B3D-F510-7B2DE7BEA8C6 任务ID_ 68 --历史任务ID_73 流程定义ID_ _3701622B-4133-7B3D-F50F-E14B4F21E847:1:55 流程实例ID_ 56 流程执行ID_ 56 任务节点ID_ USERTASK04A84BE1-1133-7B3D-F511-1D0B7BB0A668 任务ID_ 74 SELECT T.*, T.ROWID FROM ACT_HI_ACTINST T; ----------------------------------------流程变量信息-------------------------------------------------- --正在执行的流程变量信息 SELECT T.*, T.ROWID FROM ACT_RU_VARIABLE T; --历史流程变量信息 存放历史表单重要信息 --流程实例ID_ 56 执行实例ID_ 56 任务ID_ SELECT T.*, T.ROWID FROM ACT_HI_VARINST T; -------------------------------------------历史意见信息----------------------------------------------- --历史审批意见表 --任务ID_ 68 流程定义ID_ 56 SELECT T.*, T.ROWID FROM ACT_HI_COMMENT T; -----------------------------------------节点参与者信息------------------------------------------------- --任务办理人表（个人任务、组任务） SELECT T.*, T.ROWID FROM ACT_RU_IDENTITYLINK T; --历史任务办理人表（个人任务、组任务） SELECT T.*, T.ROWID FROM ACT_HI_IDENTITYLINK T; --临时对象 SELECT T.*, T.ROWID FROM EA_IST.IST_APPR_BUSI_DATA T
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" xsi:schemaLocation="http://www.springframework.org/schema/beans 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" factory-method="getTaskService" /> <bean id="historyService" factory-bean="processEngine" factory-method="getHistoryService" /> <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>
