[GitHub] [servicecomb-java-chassis] diwenzheng opened a new issue, #3021: 关于invocationContext对象 2.5.0 在多网卡下的空指针异常
diwenzheng opened a new issue, #3021:
URL: https://github.com/apache/servicecomb-java-chassis/issues/3021
目前发现一个这样的问题,
一台MAC电脑上有两个网卡,一个网卡是192.168.3.188,另一个是3.133.通过ifconfig中只能看到3.188但是对于注册中心中去绑定ip的时候使用了3.133。我尝试使用java获取ip地址的方式,确实获取到了3.133这张网卡。

没太看明白前面描述的内容与“但是使用ContextUtils.getInvoncationContext的数据均是空”之间是什么关系。你提供下你的用法吗？
如果解决多网卡情况下，需要绑定IP的问题，可以参考： https://servicecomb.apache.org/references/java-chassis/zh_CN/build-provider/listen-address-and-publish-address.html

在多网卡下默认写0.0.0.0程序应该是随机选取了一个网卡,如我上面所说.正常情况下,Controller方法进入的这个函数一定是有值的,但是在我上面的情况下,一定是空,且会导致我后续程序逻辑均为空指针异常。猜测多网卡下的逻辑,导致invocationContext对象获取的值可能是空。

还有一个疑问是我看官方有到2.7.2,之前想着后面有一个新项目,尝试使用2.7.2去构建,发现似乎你们已经移除了org.apache.servicecomb.swagger.invocation这整个包的逻辑。那么现在对于返回错误码应该怎么做？2.7.2的升级指导手册有吗。至少我看到Response，invocationContext 绝对数逻辑删除,这么大的基层逻辑改动是为了修复什么问题

没有移除 `org.apache.servicecomb.swagger.invocation这整个包的逻辑` 呀， 是不是什么地方弄错了？ 2.5.0 -> 2.7.3 并没有大的变更， release notes里面有影响使用的变更： https://servicecomb.apache.org/references/java-chassis/zh_CN/featured-topics/upgrading.html
