Spring-data-cassandra: Error creating bean with name 'sessionFactory' and Cannot resolve reference to bean 'cassandraTemplate'

Question

I have a springboot app, in which I am connecting to cassandra DB.

My pom.xml:

parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.2.6.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-cassandra</artifactId> </dependency>

The cassandraConfig definitition:

@Configuration @PropertySource("file:///Users/s1b03vf/Work/carrierhub/cass.properties") @ConfigurationProperties() @EnableCassandraRepositories(basePackageClasses = {MCSEDistributorRepository.class}) public class MSCECassandraConfig { protected String contactPoints; protected int port; protected String username; protected String password; protected String keyspace; @Override protected AuthProvider getAuthProvider() { return new PlainTextAuthProvider(username, password); } @Override protected String getKeyspaceName() { return keyspace; } @Override protected String getContactPoints() { return contactPoints; } @Override protected int getPort() { return port; } @Override public String[] getEntityBasePackages() { return new String[]{"com.example.demo.entity.cassandra"}; } }

Repository class:

@Repository public interface MCSEDistributorRepository extends CassandraRepository<MCSEDistributor, String> { }

Entity class:

 @Table("mcse_offer") public class MCSEDistributor { @Column @PrimaryKey private int id; @Column private String name; }

Now when I start my application I am running into the below error:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'documentationPluginsBootstrapper' defined in URL [jar:file:/Users/s1b03vf/.m2/repository/io/springfox/springfox-spring-web/2.9.2/springfox-spring-web-2.9.2.jar!/springfox/documentation/spring/web/plugins/DocumentationPluginsBootstrapper.class]: Unsatisfied dependency expressed through constructor parameter 1; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'webMvcRequestHandlerProvider' defined in URL [jar:file:/Users/s1b03vf/.m2/repository/io/springfox/springfox-spring-web/2.9.2/springfox-spring-web-2.9.2.jar!/springfox/documentation/spring/web/plugins/WebMvcRequestHandlerProvider.class]: Unsatisfied dependency expressed through constructor parameter 1; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'requestMappingHandlerMapping' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Unsatisfied dependency expressed through method 'requestMappingHandlerMapping' parameter 1; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mvcConversionService' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.format.support.FormattingConversionService]: Factory method 'mvcConversionService' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'MCSEDistributorRepository': Cannot resolve reference to bean 'cassandraTemplate' while setting bean property 'cassandraTemplate'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cassandraTemplate' defined in class path resource [com/example/demo/config/MSCECassandraConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.data.cassandra.core.CassandraAdminTemplate]: Factory method 'cassandraTemplate' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [com/example/demo/config/MSCECassandraConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.data.cassandra.SessionFactory]: Factory method 'sessionFactory' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'session' defined in class path resource [com/example/demo/config/MSCECassandraConfig.class]: Invocation of init method failed; nested exception is com.datastax.driver.core.exceptions.DriverInternalError: Unexpected exception thrown

It says dependency and bean creation issue for cassandraTemplate and sessionFactory. I am new to using spring-data, so not sure what I am missing here.

From startup log, I can see that it is using the below driver version:

2020-06-08 22:44:57.782 INFO 42129 --- [ restartedMain] com.datastax.driver.core : DataStax Java driver 3.7.2 for Apache Cassandra

Hey. This error is not related to spring data. You have a problem initializing the cassandra driver. Can you share the driver properties file? I also suggest you take a look at this awesome toturial, very eaay to understand and follow step by step baeldung.com/cassandra-datastax-java-driver — eladyanai

It seems like you are missing the session part. Look at the tutorial above, it will solve your issue. — eladyanai

But isn't that already taken care by the spring-data-cassandra? — Somen Biswas

Try calling super and then set the required properties

@Bean public CassandraClusterFactoryBean cluster() { CassandraClusterFactoryBean cluster = super.cluster(); cluster.setContactPoints("127.0.0.1"); cluster.setPort(9142); return cluster; }

The answer is absolete 2024 - github.com/spring-projects/spring-data-cassandra/pull/167

Figured out the issue. Issue was that the CassandraConfig class was missing this:

@Override protected boolean getMetricsEnabled() { return false; }

Added this and it started running fine.

There is something wrong with your @configuration class. it doesn't have @bean annotations. look at this example cassandra @configuration class from: https://www.baeldung.com/spring-data-cassandra-tutorial

@Configuration public class CassandraConfig extends AbstractCassandraConfiguration { @Override protected String getKeyspaceName() { return "testKeySpace"; } @Bean public CassandraClusterFactoryBean cluster() { CassandraClusterFactoryBean cluster = new CassandraClusterFactoryBean(); cluster.setContactPoints("127.0.0.1"); cluster.setPort(9142); return cluster; } @Bean public CassandraMappingContext cassandraMapping() throws ClassNotFoundException { return new BasicCassandraMappingContext(); } }

There is also explanation on how to configure the repository and table.

This answer seems absolete now - github.com/spring-projects/spring-data-cassandra/pull/167
