Java 升级到Spring boot 2.3.5.0版本后的Cassandra身份验证问题

我们正在升级到Spring boot 2.3.5.0版本。我们的应用程序将cassandra作为数据库之一，并在节点上启用了身份验证。在更新spring启动版本后尝试连接casssandra db时，我遇到了此异常，无法启动应用程序

Authentication error on node <IP:PORT> requires authentication (org.apache.cassandra.auth.PasswordAuthenticator), but no authenticator configured

}

---

我在构建CqlSession时提供用户名和密码，但仍面临此异常。有什么我做得不对吗？

在较旧的Spring数据版本中，您可以使用：

CassandraClusterFactoryBean

。但这里是一个未来的例子，如果其他人在使用spring数据cassandra 3.0.1时遇到了用户名和密码身份验证的问题，就像滚动到页面末尾一样，那么您将看到

CassandraClusterFactoryBean

被删除，而不是我们现在的

CqlSessionFactoryBean

。因此，示例代码与

import lombok.Getter;
import lombok.Setter;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.cassandra.config.AbstractCassandraConfiguration;
import org.springframework.data.cassandra.repository.config.EnableCassandraRepositories;
import org.springframework.data.cassandra.config.CqlSessionFactoryBean;

@Configuration
@EnableCassandraRepositories(basePackages = {"com.some.package"})
@ConfigurationProperties(prefix = "spring.data.cassandra")
@Getter
@Setter
public class CassandraConfig extends AbstractCassandraConfiguration {

    private String keyspaceName;
    private String contactPoints;
    private int port;
    private String localDataCenter;
    private String username;
    private String password;

    @Bean
    @Override
    public CqlSessionFactoryBean cassandraSession() {
        CqlSessionFactoryBean cassandraSession = super.cassandraSession();//super session should be called only once
        cassandraSession.setUsername(username);
        cassandraSession.setPassword(password);
        return cassandraSession;
    }

}

import org.springframework.context.annotation.Bean;

    }
