AI助手支持GPT4.0

今天遇到这个问题搞了很久

Caused by: org.xml.sax.SAXParseException: TargetNamespace.1: 应为名称空间 'http://code.alibabatech.com/schema/dubbo', 但方案文档的目标名称空间为 'http://dubbo.apache.org/schema/dubbo'。

网上也是抄来抄去，后来去谷歌查到了答案。

只需要把

<dependency>
	<groupId>com.alibaba</groupId>
	<artifactId>dubbo</artifactId>
	<version>2.6.0</version>
</dependency>

改为

<dependency>
	<groupId>org.apache.dubbo</groupId>
	<artifactId>dubbo</artifactId>
	<version>2.7.0</version>
</dependency>

把groupId 换下就好了。
