修改jbpm提供的spring.jbpm.cfg.xml，application.xml，jbpm.tx.spring.cfg.xml，jbpm.tx.hibernate.cfg.xml来做spring与jbpm的集成， <jbpm-configuration>
<process-engine-context>
<!--结合jbpm.tx.hibernate.xml-->
<command-service name="txRequiredCommandService">
<skip-interceptor />
<retry-interceptor />
<environment-interceptor />
<!--使用spring管理transaction-->
<spring-transaction-interceptor />
</command-service>
<command-service name="newTxRequiredCommandService">
<retry-interceptor />
<environment-interceptor policy="requiresNew" />
<spring-transaction-interceptor current="true"/>
</command-service>
<!--下面为jbpm.default.cfg.xml中的配置，由于jbpm.default.cfg.xml中需要引入jbpm.hibernate.cfg.xml，所以将配置改写到这里，或改jbpm.hibernate.cfg.xml源码，将引入jbpm.hibernate.cfg.xml注掉-->
<repository-service />
<repository-cache />
<execution-service />
<history-service />
<management-service />
<identity-service />
<task-service />
<object class="org.jbpm.pvm.internal.id.DatabaseDbidGenerator">
<field name="commandService">
<ref object="newTxRequiredCommandService" />
</field>
</object>
<object class="org.jbpm.pvm.internal.id.DatabaseIdComposer"
init="eager" />
<script-manager default-expression-language="juel"
default-script-language="juel">
<script-language name="juel"
factory="org.jbpm.pvm.internal.script.JuelScriptEngineFactory" />
</script-manager>
<types resource="jbpm.variable.types.xml" />
<address-resolver />
</process-engine-context>
<transaction-context>
<!--强制从当前线程中获取, 删掉了原来的<transaction />-->
<hibernate-session factory="hibernateSessionFactory" current="true" />
<!--jbpm.default.cfg.xml中的配置-->
<repository-session />
<db-session />
<message-session />
<timer-session />
<history-session />
</transaction-context>
</jbpm-configuration>
接下来将spring.jbpm.cfg.xml改为
<jbpm-configuration> <import resource="jbpm.jpdl.cfg.xml" /> <import resource="spring/jbpm42.spring.cfg.xml" /> <import resource="jbpm.identity.cfg.xml" /> <import resource="jbpm.businesscalendar.cfg.xml" /> <import resource="jbpm.console.cfg.xml" /> <!-- <import resource="jbpm.jobexecutor.cfg.xml" />--> </jbpm-configuration> 最后将applicationContext.xml改为

</beans>
修改完成。 途中出现的错误： exception while executing command org.jbpm.pvm.internal.cmd.DeployCmd@ java.lang.NullPointerException 开始在网上找原因说是因为少了这么两句： <deployer-manager> 但我是引入了jbpm.jpdl.cfg.xml的，不需要加这两句，后来跟代码发现repositorySession 为null 是由于没有加入<repository-session />所致。

谢谢了，下午试着更新了一下，无法保持的同一个事务中，呵呵。
用下面这个就好了。 <hibernate-session factory="hibernateSessionFactory" current="true" /> |
