@Test

void testProcessEngine() throws Exception { ProcessEngine processEngine = (ProcessEngine) ac.getBean( “processEngine” ); System.out.println(processEngine);
}

业务层获取ProcessEngine方式：
@Resource
private ProcessEngine processEngine
注意：如果启动程序的时候包错的内容是关于el表达式错误信息
处理方式：
里面不包含jbpm的juel-api.jar juel-engine.jar juel-impl.jar这三个jar包 ，因为这三个jar包自带的el表达式需要的jar包 而且版本比tomcat里面自带的lib包的el.jar版本高，所有应该删除jbpm的这三个jar包 拷贝到tomcat的lib包下
