java - Cassandra - 写入错误。怎么解决呢？

Question

在我们公司，我们做了一个项目，使用apache、Cassandra。直到最近，我们还使用了一位老司机。昨天，我们尝试将其替换为最新的4.3.0。我们连接到数据库，一切正常。问题是当我尝试替换 Ear 文件或添加另一个使用相同代码的子项目时。

此时，我收到此错误。

我尝试在互联网上寻找这个问题，研究他们的文档。我没有找到解决方案。

我连接到数据库的非常基本的代码。

@PostConstruct
public void start() {
    log.info("start");
    CqlSessionBuilder builder = CqlSession.builder();
    builder.addContactEndPoint(new DefaultEndPoint(new InetSocketAddress("127.0.0.1", 9042)));
    builder.withLocalDatacenter("datacenter1");
    session = builder.build();
}

@PreDestroy
public void stop() {
    log.log(Level.INFO, "stop");
    session.close();
}

我使用wildfly作为服务器。当我替换 Ear 文件或使用相同代码添加另一个文件时，出现错误。

有什么解决办法吗？

我有一个解决方案。经过两天的搜索和测试，我发现了一个错误。该错误存在于 Wildfly18、io.netty 中。一旦我将 io.netty-all 打包到项目中并删除了 Wildfly 提供的一切，一切就正常了。

可能 Wildfly18 提供了一些错误版本。
