记dubbo集成Failed to refer invoker for interface与NoClassDefFoundError的错误

dubbo用的3.1.1的版本,消费者通过xml的形式配置,启动的时候会报错,但是不影响使用
报错信息如下:

java.lang.IllegalStateException: Extension instance (name: rest, class: interface org.apache.dubbo.rpc.Protocol) couldn't be instantiated: null

看样子是缺了包,最终在网上无意间看到有人说是resteasy-client版本太高的问题
直接引入低版本依赖

<dependency>
        <groupId>org.jboss.resteasy</groupId>
         <artifactId>resteasy-client</artifactId>
          <version>3.15.3.Final</version>
</dependency>

不再报错了,可以尝试更高一点的版本,使用临界版本即可
