@JFinal @杜福忠 看了你们的创业分享,然后回想了一下自身的想法;感触颇深,有时候总站在技术的角度上去考虑了;总觉得一个很奇葩的功能,做出来对项目本身没有好处,反而会让后期难扩展,难维护,不易读懂;等很多问题;到现在都还有一种是否要权衡一下中间的利益的想法?是否真的就以产品是上帝的心里去实现功能?

jfinal,冲鸭。。。。请教一下enjoy怎么前后端分离?

2019-03-12 12:25

认真看完了,也懂了,就是没思路,准备动手copy代码来测试看,感谢分享

2019-03-09 14:27

同问一下,事务应该怎么办?

2018-07-02 08:43

@JFinal 我没改ClientAbortException 有关信息,也不知道怎么改动;在开发环境还会报错,但是我代码拿到生产环境和测试环境都不报错了;

2018-06-29 10:31

@JFinal 感谢波总指点,问题已经解决了;tomcat的版本是一个问题,其中还有一个问题是在报错之前有一句提示我给忽略了:Cannot forward to error page for request [/] as the response has already been committed. As a result, the response may have the wrong status code. If your application is running on WebSphere Application Server you may be able to resolve this problem by setting com.ibm.ws.webcontainer.invokeFlushAfterService to false
只需要在springboot的启动类Application中加入:setRegisterErrorPageFilter(false);就可以了;我的项目是springboot+jfinal+dubbo的架构;

@JFinal 谢谢指导,换了8.5.32还是不得行,换了9.0.10还是不得行;继续研究中....

@JFinal 我替换到了3.4的版本还是报以下异常,当用户在页面狂按F5刷新的时候报这个,其他都正常:

@JFinal 波总什么时候给jfinal集成一下这样的插件吧;我想加一个就是没思路,像spring那样用注解对应每一个queue或者topic;求指点;

@sphsyv 你好,请问一下你的这种配置方式,只可以配置一个queue。如何才能配置多个queue(qa,qb,qc),让消费者a去收qa,消费者b收qb,消费者c收qc。求指点。。。。。。

@bussanq 谢谢指导,顺便提醒一下如果页面要取session的话需要设置: jfr.setSessionInView(true);//是否支持以 #(session.value) 的方式访问 session
