jbpm 工作流（二）
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
