tomcat + mysql 环境下osworkflow的持久化

1、将osworkflow-2.7.0-example.war复制到tomcat_home\webapps下！启动服务后自动部署

2、在mysql中建立数据库，名称osworkflow(各人自定)

3、将mysql的jdbc引擎复制到tomcat_home\common\lib中！

4、在tomcat_homt\conf\Catalina\localhost中建立文件osworkflow-2.7.0-example.xml

     内容如下：

     <?xml version='1.0' encoding='utf-8'?>
<Context path="/osworkflow-2.7.0-example" docBase="osworkflow-2.7.0-example" debug="0" reloadable="true" crossContext="true">
   <Logger className="org.apache.catalina.logger.FileLogger" prefix="localhost_sessiontest_log." suffix=".txt" timestamp="true"/>
   <Environment name="maxExemptions" type="java.lang.Integer" value="15"/>
   <Parameter name="context.param.name" value="context.param.value" override="false"/>
   <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>maxActive</name>
     <value>100</value>
   </parameter>
   <parameter>
     <name>maxIdle</name>
     <value>30</value>
   </parameter>
   <parameter>
     <name>maxWait</name>
     <value>10000</value>
   </parameter>
   <parameter>
    <name>username</name>
    <value>root</value>
   </parameter>
   <parameter>
    <name>password</name>
    <value></value>
   </parameter>
   <parameter>
      <name>driverClassName</name>
      <value>org.gjt.mm.mysql.Driver</value>
   </parameter>
   <parameter>
     <name>url</name>
     <value>jdbc:mysql://localhost:3306/osworkflow</value>
   </parameter>
</ResourceParams>
</Context>

5、修改tomcat_home\webapps\osworkflow-2.7.0-example\WEB-INF\classes中的下列文件，没有的则新增

（1）、osuser.xml

<opensymphony-user>
    <provider class="com.opensymphony.user.provider.jdbc.JDBCAccessProvider">
        <property name="user.table">OS_USER</property>
        <property name="group.table">OS_GROUP</property>
        <property name="membership.table">OS_MEMBERSHIP</property>
        <property name="user.name">USERNAME</property>
        <property name="user.password">PASSWORDHASH</property>
        <property name="group.name">GROUPNAME</property>
        <property name="membership.userName">USERNAME</property>
        <property name="membership.groupName">GROUPNAME</property>
        <property name="datasource">java:comp/env/jdbc/oswf</property>
    </provider>
    <provider class="com.opensymphony.user.provider.jdbc.JDBCCredentialsProvider">
        <property name="user.table">OS_USER</property>
        <property name="group.table">OS_GROUP</property>
        <property name="membership.table">OS_MEMBERSHIP</property>
        <property name="user.name">USERNAME</property>
        <property name="user.password">PASSWORDHASH</property>
        <property name="group.name">GROUPNAME</property>
        <property name="membership.userName">USERNAME</property>
        <property name="membership.groupName">GROUPNAME</property>
        <property name="datasource">java:comp/env/jdbc/oswf</property>
    </provider>
    <provider class="com.opensymphony.user.provider.jdbc.JDBCProfileProvider">
        <property name="user.table">OS_USER</property>
        <property name="group.table">OS_GROUP</property>
        <property name="membership.table">OS_MEMBERSHIP</property>
        <property name="user.name">USERNAME</property>
        <property name="user.password">PASSWORDHASH</property>
        <property name="group.name">GROUPNAME</property>
        <property name="membership.userName">USERNAME</property>
        <property name="membership.groupName">GROUPNAME</property>
        <property name="datasource">java:comp/env/jdbc/oswf</property>
    </provider>

   
    <!--
Authenticators can take properties just like providers.

This smart authenticator should work for "most" cases - it dynamically looks up
the most appropriate authenticator for the current server.
-->
<!-- authenticator class="com.opensymphony.user.authenticator.SmartsAuthenticator" /-->
</opensymphony-user>

（2）、osworkflow.xml

<osworkflow>
<!--
    <persistence class="com.opensymphony.workflow.spi.memory.MemoryWorkflowStore"/>

</persistence>   

    <factory class="com.opensymphony.workflow.loader.XMLWorkflowFactory">
        <property key="resource" value="workflows.xml" />
    </factory>
</osworkflow>

（3）、propertyset.xml

<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.float" value="FLOAT_VALUE"/>
        <arg name="col.number" value="NUMBER_VALUE"/>
    </propertyset>
</propertysets>

红色标记处都是数据库连接设置，全部一样！

蓝色部分必须写上，否则连不上，至少我是这样！呵呵~

启动tomcat以后，进入osworkflow-2.7.0-example，首先创建拥护和组，用户名为test，密码为test，创建组为foos，将用户test分配到foos组中，这样就可以用test用户登陆，并且可以开始运行example流程了！
