JRebel对Dubbo的支持情况

[刘显波 <yd...@126.com>]

各位dubbo的开发大神,你们好:
       最近,我简单测试了一下在JRebel的环境下启动dubbo的demo应用,然后将一个sayHello2方法改名为sayHello3.从命令行发现sayHello3已可见,却不可调用; 
新增方法,新增入参属性等也是如此,我猜应该和dubbo操作class的方式有关.
       我们的项目基于dubbo, 开发时经常调整入参/返回值的属性.JRebel能为开发节约很多编译/重启时间,请问你们有没有什么好的热部署解决方案或者后续支持计划呢?


将sayHello2改为sayHello3后:




感谢!

Hello, Xianbo, would you mind to file one issue on GitHub [1]? I guess
jRebel doesn't work with Dubbo is because the way how Dubbo manipulate
classes.

显波，麻烦你在 github issue [1] 报个 issue 吗？可能是 jRebel 不支持 dubbo
目前生成代码的方式，我们需要深入调研一下。

Thanks,
-Ian.

That's true, you can check this
class: org.apache.dubbo.common.bytecode.Wrapper, it holds all providers'
class here.

Arthas(github.com/alibaba/arthas) can also show the proxy code:

So after you change the method name, it success, but the proxy won't
generate again.
