Netty 运行时验证，NioEventLoopGroup

Question

我一直在调试我的环境，突然间我收到了 Netty 的验证错误。

Netty的版本是4.1.46.Final,JavaJDK版本是11 compile and runtime.

我使用 Guice，但除了初始化这个 class 之外，它对 netty 部分没有任何作用，不久前我在另一个项目设置中也遇到了这个错误，而我根本没有使用 Guice。

我试过使caches/restarting无效，-U用maven更新我的依赖，甚至卸载intellij，以及-noverify什么都不做。

我的代码：

class LoginService @Inject constructor() : AbstractIdleService()
{

    private lateinit var bootstrap : ServerBootstrap

    @Inject private lateinit var configuration: RSEEnvironment

    @Inject private lateinit var channelHandler: LoginChannelHandler

    private val bossGroup = NioEventLoopGroup(1)

    private val workerGroup = NioEventLoopGroup(Runtime.getRuntime().availableProcessors())

    private lateinit var future: ChannelFuture

    override fun startUp()
    {

        val hostAddress = configuration.getString("default_host")

        val hostPort = configuration.getInt("default_port")

        bootstrap = ServerBootstrap()

        bootstrap
            .group(bossGroup, workerGroup)
            .channel(NioServerSocketChannel::class.java)
            .childHandler(channelHandler)
            .option(ChannelOption.SO_KEEPALIVE, true)
            .option(ChannelOption.TCP_NODELAY, true)

        future = bootstrap.bind(hostAddress, hostPort).syncUninterruptibly()

        future.channel().closeFuture().sync()

    }

    override fun shutDown()
    {

        workerGroup.shutdownGracefully()

    }

    @Provides fun fetchEnvironment() = RSEEnvironment()

}

错误：

------------更新--------

如果我在我的项目中创建另一个模块并只执行基本代码，它在同一个 Maven 父级上工作正常。

Answer 1

这听起来像是 class 路径问题。在我看来，您在 class 路径上有多个版本的 netty。确保只有一个。

Netty 运行时验证，NioEventLoopGroup

Netty Verify on runtime, NioEventLoopGroup

java

maven

netty

kotlin
