activiti用dubbo分布服务

dubbo手册地址：https://www.gitbook.com/@dubbo

dubbo包地址：http://dubbo.io/

实现非常简单，难点在于dubbo调优。简单就是接口都是现成的，实现类还是现成的，所以你只需要配置就行了。

项目用的是SSM，如果不需要或者不一样 注意下面的pom配置文件。

我不建议扫包这种方式，因为后期还得配置好多，要么都得在类上声明，不方便啊。

</beans>

在类上注释的样子。

 

配置dubbo你可能遇到两个问题，一个就是小红叉问题：http://blog.csdn.net/jiao_zg/article/details/64439525

还有一个就是消费方找不到你的类，报出让你重新注册这个那个滴，这不是你配置的问题，是你的提供方和消费方的这个要用的类路径不一致。当然，你要是不用扫包，用引用的方式还有这个问题，那就可能是这个解决方式，也可能不是，多搜搜吧。
