一种高效的寻路算法 - B*寻路算法
最近工作中一个项目打算采用工作流技术,所以对工作流特别是OSWorkflow进行了一些学习和研究,为了向项目组其他成员演示和进一步进行应用,做了这个小业务系统,现在经过整理把它拿出来,希望对想要了解OSWorkflow的朋友有一点帮助。我接触的时间也不长,所以哪个地方有问题还希望大家多多指点,对工作流技术共同提高。
这个小业务系统的主要目的
演示如何基于OSWorkflow构建业务系统,即如何将原来程序内硬编码的业务过程抽取出来,放到底层的工作流引擎中,上层业务模块只进行具体业务动作的执行,同时演示着两层如何“集成”。
本系统演示三个方面:业务处理和OSWorkflow的基本“集成”、工作流引擎根据工作流定义调用业务处理逻辑、基于业务数据的工作流跳转
业务用例描述
核心工作流:
1、员工填写请假申请单,包括“请假原因”和“请假天数”,填写后进行提交;
2、部门主管对员工请假申请进行审批,同意员工请假;
3、人力资源主管对员工请假申请进行审批,同意员工请假;
4、系统发送邮件通知员工请假申请已获得批准;
5、用例结束;
备选工作流1:
在第一步中,如果员工请假天数小于等于3天,那么不需要部门主管审批,直接从第一步跳到第三步,又人力资源审批;
备选工作流2:
在第二步中,如果部门主管不同意请假申请,那么系统将给请假员工发送请假没有通过的邮件通知,用例结束;
备选工作流3:
在第三步中,如果人力资源主管不同意请假申请,那么系统将给请假员工发送请假没有通过的邮件通知,用例结束;
系统运行/开发环境
数据库:ms sqlserver2000
应用服务器:Jboss-4.0.2
开发工具:Jbuilder2006
系统搭建
1、创建数据库,我命名为osworkflow_app,也可命名为任意名字,只要在数据源配置中正确配置即可;
2、创建数据表并初始化用户及用户组数据,执行附件中的db_leaveApprove_20070712.sql即可;
3、在jboss下配置数据源,我的配置如附件mssql-ds.xml
4、将osworkflow及log4j的配置文件leave_apply.xml、osuser.xml、osworkflow.xml、propertyset.xml、workflows.xml、log4j.properties拷贝到工程目录src下面;
可直接将附件的leaveApprove.rar解到项目中,里面包括所有的源程序和资源包。
工作流定义文件说明
依据本业务需求的工作流定义文件如下
定义中包括6个step
step1是员工请假申请的步骤,本步骤的action在执行时将回调业务方法类ApplyFunction,将申请单数据插入到数据库中,同时处理结果将根据请假申请天数dayCount进行判断,如果请假申请天数大于3天,将跳到step2让部门主管审批,如果不大于3天,将直接跳到step3让人力资源主管审批;
step2 是部门主管审批,如果审批同意(opinion!=2)将跳到step3再由人力资源主管审批,如果审批不同意(opinion==2)将跳到step5自动发“申请未批准”邮件通知步骤;
step3 是人力资源主管审批,如果审批同意(opinion!=2)将跳到step4自动发“申请批准”邮件通知步骤,如果审批不同意(opinion==2)将跳到step5自动发“申请未批准”邮件通知步骤;
step4和step5都是自动发送邮件通知步骤,执行完之后跳到空步骤step6结束该工作流实例。
工作流定义文件
回家了,明天再对一些程序进行说明
可以下载附件,建立工程后执行,数据库中有三个用户:employee1表示员工,可以提交请假申请;manager1表示部门主管;hr1表示人力资源主管,密码都是test
owner是一个组就是动态会签了!!
明白了,谢谢前辈
owner是一个组就是动态会签了!!
owner是一个组有2种情况,一个是只需要一个组里面的一个人办理,还有就是组里所有的人都得办理才可以到下一步,第一种情况好办,需要添加额外的一步就是把这个组里的任务变成自己私有的任务,也就是拉取任务,这个好办, 难就难在所有的人都要办理这个步骤的任务,这就是会签,osworkflow里面不怎么好办
owner是一个组就是动态会签了!!
底层持久化你可以配置spring,jdbc,等等,事务和普通的程序没啥两样!!
小弟不才,也是才接触,能否给小弟一个例子,谢谢,可以发到我的邮箱 270422767@qq.com,谢谢了
底层持久化你可以配置spring,jdbc,等等,事务和普通的程序没啥两样!!
你取得的值没有在osuser表中,所以违反了主键约束!
我也出现这个问题,
作者能否提供数据库的完整值,谢谢!

我想请教下,如果step的owner是一个组,或者我的需求中有上级审批的情况,那我的owner怎么设置呢?我感觉osworkflow的owner必须手动指定特定的一个人,我要指定多个人怎么办?因为一个审批步骤在实际中可能有多个人能审批呀。。。。小弟刚学,希望前辈能指教
owner是一个组就是动态会签了!!
明白了,谢谢前辈

会签思路我已经有了,只是没有实现,扩展split ,指示是会签,然后当运行到该split,检测传进来的owner,根据数目创建多个currentstep就行了,然后在下一个join里,把这几个step信息传过去,指示都完成才可以join

在导入这个例子的时候,碰到了很多问题
1:安装mysql数据库的时候,补丁没打
2:数据库连接,上面很多人提到log里有osuser.xml的问题是因为没有正确配置数据库连接池导致的。这个问题我看了很久,
3:接着就是以个looking name(如果我没有记错的话),我直接跳过,用了
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");// 装载驱动程序
con = DriverManager.getConnection(
"jdbc:odbc:JSQLConnectDB_LeaveApply", "sa", "××××");// 建立数据库连接
4:还有hr不能提交,确实把中文改成英文就OK了。
但是具体的流程没有看很清楚。学习中
这个例子挺好的。呵呵

你取得的值没有在osuser表中,所以违反了主键约束!

Workflow wf = new BasicWorkflow((String) session.getAttribute("username"));
Map map = new HashMap();
map.put("applicant", applicant);
map.put("reason", reason);
map.put("dayCount", new Integer(dayCount));
try {
long wfid = wf.initialize("leave_apply", 100, null);
为什么我启用一个工作流的时候会报这个错呢?

owner没有值造成的...而我session.getAttribute("username")是可以取得值的...??
