       在到处查资料,下载demo后,我终于让自己的osworkflow工作流跑了起来。环境采用了MySQL5Tomcat6JDBC做持久层。具体的步骤如下:

 

       1、创建数据库,脚本如下。

       osworkflow_app

 

    2、创建数据源,在tomcat根目录下找到conf目录里的context.xml文件,在Context节点中加入如下代码:

<Resource name="jdbc/osworkflow_app" auth="Container" type="javax.sql.DataSource"

               maxActive="100" maxIdle="30" maxWait="10000"

               username="root" password="sa" driverClassName="com.mysql.jdbc.Driver"

               url="jdbc:mysql://localhost:3306/osworkflow_app"/>

    其中,本人的数据库用户名和密码分别是rootsa,库表名称为osworkflow_app,需要修改的是数据库用户名和密码。特别注意,需要把mysql的驱动包随手丢到tomcatlib目录下。

 

       3、分别加入osworkflow的配置文件到src下面。

log4j.properties

log4j.rootLogger=debug, A1 , R

 

log4j.logger.org.apache=INFO

 

log4j.appender.A1=org.apache.log4j.ConsoleAppender

log4j.appender.A1.layout=org.apache.log4j.PatternLayout

log4j.appender.A1.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss} [%c]-[%p] %m%n

 

log4j.appender.R=org.apache.log4j.RollingFileAppender

log4j.appender.R.File=C:/OSWorkflowDemo.log

log4j.appender.R.MaxFileSize=1000KB

log4j.appender.R.MaxBackupIndex=1

log4j.appender.R.layout=org.apache.log4j.PatternLayout

log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n

4、创建自己的流程描述文件bus_zhijian1.xml。该文件我没有经过测试,只能自己学习,不能贴出来了。建议初学者可以使用仅仅两个step的描述文件进行入门的学习。

 

5、编写java类和一些FunctionProvider,完成具体的业务。
