Why Are Microservice Development Framework and Netty Versions Unmatched?
Copied.
Why Are Microservice Development Framework and Netty Versions Unmatched?
Symptom
During development of a microservice application, the following error is displayed:
"Caused by: java.lang.NoSuchMethodError: io.netty.handler.codec.http.websocketx.WebSocketClientHandshakerFactory.newHandshaker(Ljava/net/URI;Lio/netty/handler/codec/http/websocketx/WebSocketVersion;Ljava/lang/String;ZLio/netty/handler/codec/http/HttpHeaders;IZZJ)Lio/netty/handler/codec/http/websocketx/WebSocketClientHandshaker;"
Possible Cause
Third-party software introduced a mismatched version dependency.
Solution
Run the mvn dependency:tree command in the development environment to view the dependency tree and check whether the microservice development framework and Netty versions are matched.
For ServiceComb 2.0.1 development framework, the matched Netty version is 4.1.45.Final.
