JBPM4.3+SSH环境搭建(转) .

http://yy629.iteye.com/category/78025

你要用jBPM4.3，首先至少你要了解
1.UML2.0的活动图（因为jBPM是Activity Diagram模型）
2.Hibernate（因为jBPM集成了Hibernate作为引擎的持久框架）
当然最重要的是你对工作流的系统结构有初步的了解。

具体指引请参考 用户手册和开发手册，这里只是一些简单补充。
一、jBPM4.3下载
sourceforge下载
http://sourceforge.net/projects/jbpm/

svn仓库里下载
http://anonsvn.jboss.org/repos/jbpm/jbpm4

二、搭建环境（GDP在Eclipse上的安装）
当你无法在Eclipse安装jBPM4.3 GDP插件，把你的Eclipse SDK版本升级到3.42就OK了。
本人用Myeclipse8.5

三、Myeclipse8.5安装jbpm4插件
下载好的jBPM4.3解包，找到jbpm-4.3/install/src/gpd/jbpm-gpd-site.zip
菜单【Help】-【MyEclipse Configuration Center】-选中【Software】点击【add site】-【Add from Archive File】选中jbpm-gpd-site.zip 点击ok
在【Personal Sites】将里面的接口右击 add to profile ，再点击右上角 Apply 7 change。自己重启，新建就能看到jbpm的菜单，毕！

四、jBPM4.3+SSH
1.在jbpm-4.3/install/src/db/create下选择你使用的数据库脚本（总共有18张表）
2.使用jbpm-4.3/install/src/demo下的SQL脚本生成测试用的数据
3.spring2.5+
4.hibernate用jbpm4.3的包，不支持ehcache。
四、主要配置文件
jbpm.hibernate.cfg.xml

JBPM4表结构说明

JBPM4_DEPLOYMENT   流程定义表
JBPM4_DEPLOYPROP 流程定义属性表

JBPM4_EXECUTION  流程实例表
JBPM4_HIST_ACTINST 流程活动(节点)实例表

JBPM4_HIST_DETAIL  流程历史详细表

JBPM4_HIST_PROCINST 流程实例历史表

JBPM4_HIST_TASK  流程任务实例历史表
JBPM4_HIST_VAR  流程变量(上下文)历史表

JBPM4_ID_GROUP 组表
JBPM4_ID_MEMBERSHIP 用户角色表
JBPM4_ID_USER  用户表
JBPM4_JOB  定时表
JBPM4_LOB  存储表
JBPM4_PARTICIPATION 参与者表
JBPM4_SWIMLANE  泳道表
JBPM4_TASK 任务表
JBPM4_VARIABLE 上下文表

红 色的表为经常使用的表.这里不使用JBPM自己的权限角色定义.
发布一个流程deploy后
jbpm4_deployment新增一条记录
jbpm4_deployprop新增三条记录
jbpm4_lob 新增一条记录

开始一个流程startProcessInstanceByKey后
jbpm4_execution新增一条记录
jbpm4_hist_actinst 新增一条记录
jbpm4_hist_procinst新增一条记录
jbpm4_hist_task新增一条记录
jbpm4_task 新增一条记录
流程定义相关的布署信息就存储在（1） JBPM4_DEPLOYMENT、（2） JBPM4_DEPLOYPROP 及（3） JBPM4_LOB 中。上传一个包含png和jpdl.xml的zip包后，JBPM4_DEPLOYMENT多一条记录 JBPM4_DEPLOYPROP 多三条， JBPM4_LOB多两条。
（4）J B PM4_HIST_PROCINST 与（5） JBPM4_HIST_ACTINST 分别存放的是Process Instance、Activity Instance的历史记录。
（6）JBPM4_EXECUTION 主要是存放JBPM4的执行信息，Execution机制代替了JBPM3的Token机制（详细参阅JBPM4的PVM机制，过段时间我也会进一步分析）。
（7）JBPM4_TASK 存放需要人来完成的Activities，需要人来参与完成的Activity 被称为Task。
（8）JBPM4_PARTICIPATION 存放 Participation的信息，Participation的种类有Candidate、Client、Owner、 Replaced Assignee和Viewer。而具体的Participation既可以是单一用户，也可以是用户组。
（9）JBPM4_SWIMLANE。 Swim Lane是一种Runtime Process Role。通过Swim Lane，多个Task可以一次分配到同一Actor身上。
（10） JBPM4 _VARIABLE 存的是进行时的临时变量。
（11） JBPM4_HIST_DETAIL 保存 Variable的变更记录。
（12）JBPM4_HIST_VAR 保存历史的变量 。
（13） JBPM4_HIST_TASK Task的历史信息。
