1 新建一個(gè)名為oswf的Web Projcet 項(xiàng)目,并添加項(xiàng)目的? struts capabilities,并把osworkflow所需要jar文件拷貝到lib目錄下.

2 在tomcat的servers.xml文件中配置一個(gè)項(xiàng)目連接到我們所在的myeclipse工作區(qū)中所建立的oswf項(xiàng)目下的WebRoot目錄下.在servers.xml中添加如下代碼:

<Context path="/oswf" docBase="D:\peidw\workplace\osworkflow\WebRoot" debug="5" reloadable="true" crossContext="true">
??????? <Resource name="jdbc/oswf" auth="Container" type="javax.sql.DataSource"/>
????????? <ResourceParams name="jdbc/oswf">
????????? <parameter>
??????????? <name>factory</name>
??????????? <value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
????????? </parameter>
????????? <parameter>
??????????? <name>driverClassName</name>
??????????? <value>com.mysql.jdbc.Driver</value>
????????? </parameter>
????????? <parameter>
??????????? <name>url</name>
??????????? <value>jdbc:mysql://localhost:3306/osworkflow</value>
????????? </parameter>
????????? <parameter>
??????????? <name>username</name>
??????????? <value>root</value>
????????? </parameter>
????????? <parameter>
??????????? <name>password</name>
??????????? <value></value>
????????? </parameter>
????????? <parameter>
??????????? <name>maxActive</name>
??????????? <value>20</value>
????????? </parameter>
????????? <parameter>
??????????? <name>maxIdle</name>
??????????? <value>2</value>
????????? </parameter>
????????? <parameter>
??????????? <name>maxWait</name>
??????????? <value>-1</value>
????????? </parameter>
????????? <parameter>
??????????? <name>removeAbandoned</name>
??????????? <value>true</value>
????????? </parameter>
????????? <parameter>
??????????? <name>removeAbandonedTimeout</name>
??????????? <value>300</value>
????????? </parameter>
??????? </ResourceParams>
??????? </Context>

3? 在src目錄需要建立三個(gè)文件來(lái)配置OSWorkflow的相關(guān)配置.首先是osworkflow.xml文件,至于文件的作用一看就明白,內(nèi)容如下:
?????? <?xml version="1.0" encoding="UTF-8"?>
<osworkflow>
?<persistence class="com.opensymphony.workflow.spi.jdbc.JDBCWorkflowStore">
???? <property key="datasource" value="jdbc/oswf"/>
????
???? <property key="entry.sequence" value="select max(id)+1 from os_wfentry"/>
???? <property key="entry.id" value="id"/>
???? <property key="entry.name" value="name" />
???? <property key="entry.state" value="state"/>
????
???? <property key="step.sequence" value="select max(id)+1 from os_stepids"/>
???? <property key="step.sequence.increment" value="insert into os_stepids(id) values(null) "/>
???? <property key="step.sequence.retrieve" value="select max(id) from os_stepids"/>
????
???? <property key="history.table" value="os_historystep"/>
???? <property key="current.table" value="os_currentstep"/>
???? <property key="histroyPrev.table" value="os_historystep_prev"/>
???? <property key="currentPrev.table" value="os_currentstep_prev"/>
????
???? <property key="step.id" value="ID"/>
??????? <property key="step.entryId" value="ENTRY_ID"/>
??????? <property key="step.stepId" value="STEP_ID"/>
??????? <property key="step.actionId" value="ACTION_ID"/>
??????? <property key="step.owner" value="OWNER"/>
??????? <property key="step.caller" value="CALLER"/>
??????? <property key="step.startDate" value="START_DATE"/>
??????? <property key="step.finishDate" value="FINISH_DATE"/>
??????? <property key="step.dueDate" value="DUE_DATE"/>
??????? <property key="step.status" value="STATUS"/>
??????? <property key="step.previousId" value="PREVIOUS_ID"/>
????
?</persistence>
?
?<factory class="com.opensymphony.workflow.loader.JDBCWorkflowFactory">
??<property key="resource" value="workflows.xml"/>
?</factory>
</osworkflow>
在src目錄下新建一個(gè)propertyset.xml來(lái)存儲(chǔ)相應(yīng)的字段配置信息:

? <?xml version="1.0" encoding="UTF-8"?>
<propertysets>
??? <propertyset name="jdbc"
????? class="com.opensymphony.module.propertyset.database.JDBCPropertySet">
??????? <arg name="datasource" value="jdbc/oswf"/>
??????? <arg name="table.name" value="OS_PROPERTYENTRY"/>
??????? <arg name="col.globalKey" value="GLOBAL_KEY"/>
??????? <arg name="col.itemKey" value="ITEM_KEY"/>
??????? <arg name="col.itemType" value="ITEM_TYPE"/>
??????? <arg name="col.string" value="STRING_VALUE"/>
??????? <arg name="col.date" value="DATE_VALUE"/>
??????? <arg name="col.data" value="DATA_VALUE"/>
??????? <arg name="col.float" value="FLOAT_VALUE"/>
??????? <arg name="col.number" value="NUMBER_VALUE"/>
??? </propertyset>
</propertysets>
還要新建一個(gè)流程的配置文件,該文件的命名與osworkflow.xml的factory節(jié)點(diǎn)里的值有關(guān),如:

<?xml version="1.0" encoding="UTF-8"?>
<workflows>
? <workflow name="leave" type="resource" location="leave.xml"/>
</workflows>

那么leave.xml就是一個(gè)工作流的真正配置文件。其內(nèi)容如下：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE workflow PUBLIC "-//OpenSymphony Group//DTD OSWorkflow 2.7//EN" 
"http://www.opensymphony.com/osworkflow/workflow_2_7.dtd">
<workflow>
  <initial-actions>
   <action id="0" name="開(kāi)始">
      <results>
        <unconditional-result old-status="Finished" status="Queued" step="1" />
      </results>
    </action>
  </initial-actions>

  <steps>
    <step id="1" name="填假單">
      <actions>
        <action id="1" name="送出">
	  <pre-functions>
	    <function type="class">
	      <arg name="class.name">com.opensymphony.workflow.util.Caller</arg>
	    </function>
	  </pre-functions>
          <results>
            <unconditional-result old-status="Finished" status="Queued" 
step="2"  owner="User100" />
          </results>
        </action>
      </actions>
    </step>

    <step id="2" name="批假單">
      <actions>
        <action id="2" name="準(zhǔn)許">
	  <pre-functions>
	    <function type="class">
	      <arg name="class.name">com.opensymphony.workflow.util.Caller</arg>
	    </function>
	  </pre-functions>
          <results>
            <unconditional-result old-status="Finished" status="Queued" 
step="3"  owner="${caller}"/>
          </results>
        </action>

        <action id="3" name="駁回">
	  <pre-functions>
	    <function type="class">
	      <arg name="class.name">com.opensymphony.workflow.util.Caller</arg>
	    </function>
	  </pre-functions>
          <results>
            <unconditional-result old-status="Finished" status="Queued" 
step="1"  owner="${caller}"/>
          </results>
        </action>
      </actions>      
    </step>

    <step id="3" name="停止" />
  </steps>
</workflow>

這樣就可以配置OSworkflow持久化進(jìn)mysql中.
