发现是netty相关问题，查看程序pom文件中的netty依赖版本如下

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>io.netty</groupId>
            <artifactId>netty-all</artifactId>
            <version>4.1.38.Final</version>
        </dependency>
    </dependencies>
</dependencyManagement>

错误中提示netty版本为4.1.16.Final，与依赖中版本不一致，

解决办法 ：把pom文件中依赖注释掉
