终于搞定了，在此感谢chenjin的指点。
从10.31日整合失败后，这块就一直是我的心病，我甚至都跑去了http://www.springframework.org/去发了一个帖，这还是我第一次用英文问问题呢。
最后的配置结果是：
hibernate.cfg.xml、jbpm.cfg.xml在关联spring后保持不变，只需要更改spirng的配置文件就好了。
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN""http://www.springframework.org/dtd/spring-beans.dtd"> <beans> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName"> <value>com.mysql.jdbc.Driver</value> </property> <property name="url"> <value>jdbc:mysql://localhost:3306/test</value> </property> <property name="username"> <value>root</value> </property> <property name="password"> <value/> </property> </bean> <!-- Hibernate SessionFactory --> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource"> <ref local="dataSource"/> </property> <property name="mappingLocations"> <value>classpath*:/org/jbpm/**/*.hbm.xml</value> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> <prop key="hibernate.jdbc.batch_size">0</prop> </props> </property> </bean> <!-- Transaction manager for a single Hibernate SessionFactory (alternative to JTA) --> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory"> <ref local="sessionFactory"/> </property> </bean> <!-- reading jBPM process definitions --> <bean id="websaleWorkflow1" class="org.springmodules.workflow.jbpm31.definition.ProcessDefinitionFactoryBean"> <property name="definitionLocation" value="processdefinition.xml"/> </bean> <!-- jBPM configuration--> <bean id="jbpmConfiguration" class="org.springmodules.workflow.jbpm31.LocalJbpmConfigurationFactoryBean"> <property name="sessionFactory" ref="sessionFactory"/> <property name="configuration" value="jbpm.cfg.xml"/> <property name="processDefinitions"> <list> <ref local="websaleWorkflow1"/> </list> </property> <property name="createSchema" value="true"/> </bean> <!-- jBPM template --> <bean id="jbpmTemplate" class="org.springmodules.workflow.jbpm31.JbpmTemplate"> <constructor-arg index="0" ref="jbpmConfiguration"/> <constructor-arg index="1" ref="websaleWorkflow1"/> </bean></beans>
其中
<property name="mappingLocations"> <value>classpath*:/org/jbpm/**/*.hbm.xml</value> </property>很关键，我就是想spring会通过jbpm找到hibernate.cfg.xml而没有设置，才失败的。
