Camunda 流程执行错误处理ERROR BOUNDARY EVENT

 ERROR BOUNDARY EVENT：在任务发生异常时候会触发走，在代码中必须显式抛出

throw new BpmnError("error.....");

public void execute(DelegateExecution delegateExecution) throws Exception {
        System.out.println("进来了>>>>>>>>>>>>>");
        delegateExecution.setVariable("num",1);
        try {
            System.out.println(1/0);
        } catch (Exception e) {
            //ERROR BOUNDARY EVENT 显式声明，否则不起作用
            throw new BpmnError("error.....");
        }
        Thread.sleep(10000);
    }
