@Test
public 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

 

 

技术分享   

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
