1 概述

本文主要介绍如何将 JBPM+Struts+Spring+Hibernate整合在一块。并通过一个简单实例来说明。此实例为一个申请审批的简单流程，并将申请人和审批人记录到数据库中，流程为start----申请----审批----end，中间无退回，无分支，只是看一下 jbpm的流程设计，本文将 jbpm和struts/spring/hibernate结合在一块做为一个完整的项目来叙述。

通过 processdefinition.xml的可视图，可了解一下流程图：

2 环境

tomcat6.0+jdk1.5+eclips3.2

jbpm3.1.4

spring2.0

hibernate3

数据库：postgreSql8.1

jbpm提供了在eclipse下的一个可视化插件，通过它我们可以方便的定义工作流,介绍一下eclipse如何添加该插件？

打开jbpm-starters-kit-3.1.4/jbpm-designer/jbpm-gpd-feature目录，我们可以看到下面有一个eclipse文件夹，这里我们通过link的方式为eclipse添加该插件。

在 {eclipse_home}/link文件夹下新建jbpm-designer.link文件，用记事本打开该文件加入如下一行：

path=D://jbpm-starters-kit-3.1.4//jbpm-designer//jbpm-gpd-feature

后面的路径即为该插件的存放路径，根据个人情况修改。注意，这里的分隔符使用双斜杠 //或者用单斜杠/。

3 项目总体结构

src部分

WebRoot部分：

4 要引入的jar包

很多jar包是从jbpm-starters-kit-3.1.4/jbpm-starters-kit-3.1.4/jbpm/build

和jbpm-starters-kit-3.1.4/jbpm-starters-kit-3.1.4/jbpm/lib中得到的

其中spring-modules-jbpm31.jar、postgresql-8.1-405.jdbc2.jar要下载

以下是 myeclips需要引入的包

10 代码说明

10.1代码包结构

在 src/com/目录下面，有包

com.binghe.hibernate.dao 存放 dao类，调用 jbpm的方法操作数据库

com.binghe.pub 存放公共的信息，如字符集乱码的处理等等，不用的话可以在 web.xml中不加载，本文不赘述。

com.binghe.struts.action 存放 sturts中的action，与 jsp页面交互

com.binghe.struts.form 存放 sturts中的form，存放 jsp页面中的提交数据

com.binghe.jpdl 存放 jbpm的流程文件

Jsp部分：

apply.jsp 申请 jsp，输入申请人， web.xml中已将此页面为welcome页面

approve.jsp 审批 jsp，输入审批人

end.jsp 结束 jsp，显示申请人和审批人
