Corda 尝试使用RPC连接节点时出错

当我尝试从客户端建立RPC连接时，节点日志中出现以下异常。client.start（）方法似乎被卡住了。代码如下。我在Jetty托管的servlet中运行此代码

        final NetworkHostAndPort nodeAddress = NetworkHostAndPort.parse("localhost:10008");
        final CordaRPCClient client = new CordaRPCClient(nodeAddress, CordaRPCClientConfiguration.DEFAULT);
        // Can be amended in the com.example.Main file.
        CordaRPCConnection clientConn= client.start("user1","password");

        rpcOps =clientConn.getProxy();

        rpcOps.waitUntilNetworkReady();

下面是我在节点日志中看到的异常

我在测试中遇到了类似的问题，结果证明我的客户端库与服务器的版本不同。错误日志显示服务器具有3.2版本。客户端上的RPC版本是什么？

您是正确的。我在客户端上的版本是2.2.0。你是对的。我在客户端上的版本是2.2.0。
