jBPM4实战系列(二)jBPM4.4+ssh 整合配置及完整实例

来源：互联网发布：域通电话软件编辑：程序博客网时间：2024/05/18 22:55

整合jBPM4.4+ssh过程(spring 接管struts2和hibernate，例中都整合在application.xml中，没有单独的jbpm.hibernate.cfg.xml)：

1.在sessionFactory的mappingLocations属性加入以下几个jbpm.*.hbm.xml由jBPM自带

                <value>classpath:jbpm.repository.hbm.xml</value>
                <value>classpath:jbpm.execution.hbm.xml</value>
                <value>classpath:jbpm.history.hbm.xml</value>
                <value>classpath:jbpm.task.hbm.xml</value>
                <value>classpath:jbpm.identity.hbm.xml</value>

2.jBPM自己内部的配置(spring来接管processEngine)

<bean id="springHelper" class="org.jbpm.pvm.internal.processengine.SpringHelper" />
<bean id="processEngine" factory-bean="springHelper" factory-

method="createProcessEngine" />

这样子就配好啦。只要在要用的地方注入processEngine就可以了！简单吧

3.当然为了编程的方便，可以自己写个工具类，直接就可以通过注入这个类来获取所需要的jBPM服务

当然其他的配置还是比较多的。大家可以参照我前一篇文章。

ok.基本就是这样。具体的大家可以直接看项目

运行环境：myeclipse8.5+jBPM4.4+jdk1.6+sql server 2000(貌似网上没找到这种建表语句。所以我也上传了)。

其他的主要建表语句在\install\src\db下面。

比较大，jar包都没有放的。
