我正在尝试通过java datastax驱动程序通过openssl连接到cassandra集群,此文档https://docs.datastax.com/en/developer/java-driver/3.1/manual/ssl/使用我的客户端证书和密钥,以及作为cassandra集群的信任库需要双向相互证书认证
这是我的代码
public static void main( String[] args ) throws Exception
{
KeyStore ks = KeyStore.getInstance("JKS");
// make sure you close this stream properly (not shown here for brevity)
InputStream trustStore = new FileInputStream("MyTrustStore");
ks.load(trustStore, "abcdef".toCharArray());
TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
tmf.init(ks);
SslContextBuilder builder = SslContextBuilder
.forClient()
.sslProvider(SslProvider.OPENSSL)
.trustManager(tmf)
// only if you use client authentication
.keyManager(new File("client_cert"), new File("private_key"));
SSLOptions sslOptions = new NettySSLOptions(builder.build());
Cluster cluster = Cluster.builder()
.addContactPoint("w.x.y.z")
.withSSL(sslOptions)
.build();
}
在pom中具有以下依赖项
<dependencies>
<dependency>
<groupId>com.datastax.cassandra</groupId>
<artifactId>cassandra-driver-core</artifactId>
<version>3.6.0</version>

但是我得到一个错误

我尝试从pom中删除无聊的静态dep或tcnative dep,但它似乎仍然不起作用。任何帮助将不胜感激。
提前谢谢
答案 0 :(得分:2)
我怀疑此处可能发生的情况是由于此处使用的netty
,netty-tcnative
和netty-tcnative-boringssl-static
版本之间的某些不兼容引起的。
在先前的实验中,我发现netty
和netty-tcnative
的版本特别重要,因为两者之间可能存在不兼容性。
datastax Java驱动程序3.6.0依赖于netty 4.0.56.Final,并将netty-tcnative 2.0.7.Final列为可选依赖项。您也可以find in the documentation对于Java驱动程序3.6.0,建议使用2.0.7.Final:
netty-tcnative的较新版本与驱动程序使用的netty版本之间存在已知的运行时不兼容性。为了获得最佳效果,请使用2.0.7.Final版本。
我还怀疑未使用相同版本的netty-tcnative
和netty-tcnative-boringssl-static
可能会导致不兼容。我建议尝试相同的版本。
由于我已经对此进行了测试,因此我将首先尝试以下配置:
