@YunaiV
dubbo 里 RestProtocol 这个类：

应该是 resteasy-netty4 这个jar版本不对，不知道应该用哪个

[liuhonglin]

I got
add dependency:

io.netty
netty-all

    <dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-jaxrs</artifactId>
    </dependency>

    <dependency>
        <groupId>org.jboss.resteasy</groupId>
