第一个Activiti5.13 + Spring3.x例子

参考： http://www.iteye.com/topic/1130389

database不能使用

    <bean id="dataSource" class="org.springframework.jdbc.datasource.SimpleDriverDataSource">
        <property name="driverClass" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://192.168.0.196:3306/activiti_demo" />
        <property name="username" value="root" />
        <property name="password" value="" />
    </bean>

，否在很慢，应该使用

    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://192.168.0.196:3306/activiti_demo" />
        <property name="username" value="root" />
        <property name="password" value="" />
    </bean>

自动部署的配置:

<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">  
  ...  
  <property name="deploymentResources" value="classpath*:/org/activiti/spring/test/autodeployment/autodeploy.*.bpmn20.xml" />  
</bean>
