Unable to connect to cassandra 4.0 after upgrading the spring-boot to latest 2.6.6 version
I am trying to upgrade Spring Boot to 2.6.6 which is using spring core-5.3.18 & spring-beans is 5.3.18. But I am facing some issues with Cassandra connection: codebase is not able to establish the connection with Cassandra.
The Cassandra version that we are using is 4.0.1 and driver dependencies are:
<dependency>
<groupId>com.datastax.oss</groupId>
<artifactId>java-driver-core</artifactId>
<version>4.13.0</version>
</dependency>
<dependency>
<groupId>com.datastax.oss</groupId>
<artifactId>java-driver-query-builder</artifactId>
<version>4.0.1</version>
</dependency>
Below is the error that I am getting on server startup :
Caused by: com.datastax.oss.driver.api.core.AllNodesFailedException: Could not reach any contact point, make sure you've provided valid addresses (showing first 1 nodes, use getAllErrors() for more): Node(endPoint=/127.0.0.1:9042, hostId=null, hashCode=7be37940): [com.datastax.oss.driver.api.core.connection.ConnectionInitException: [s2|control|connecting...] Protocol initialization request, step 1 (OPTIONS): failed to send request (io.netty.channel.StacklessClosedChannelException)]

The exception tells me that an attempt was made to connect to 127.0.0.1:9042 but the connection was refused. Spring Boot isn't really involved at this stage so it's not clear to me why upgrading Spring Boot would cause this problem. It's also hard to comment further without know that version of Spring Boot that you have upgraded from.
First of all, I would verify that Cassandra is listening on 127.0.0.1:9042. If it is and you can connect to it with clients other than your Spring Boot application, then please provide a minimal sample that reproduces this behaviour and we can take a look. You can share the sample with us by zipping it up and attaching it to this issue or by pushing it to a separate repository on GitHub.
If you would like us to look at this issue, please provide the requested information. If the information is not provided within the next 7 days this issue will be closed.
Closing due to lack of requested feedback. If you would like us to look at this issue, please provide the requested information and we will re-open the issue.
Hi , I have got same issue , when upgrading spring boot 2.7.8 to 3.0.3 leads me to upgrade spring-data-cassandra from 3.0.2.RELEASE to 4.0.5 else if not do so , I was getting this :

is this not because of spring boot upgrade then ?, the issue seems in autoconfiguring?
