【Cassandra】Cassandra在spring boot中的使用

1、depedency

<dependency>
  <groupId>org.springframework.data</groupId>
  <artifactId>spring-data-cassandra</artifactId>
</dependency>

2、properties

spring.data.cassandra.keyspace-name=XXXX
spring.data.cassandra.contact-points=XXXX
spring.data.cassandra.port=1111
spring.data.cassandra.username=xxxxx
spring.data.cassandra.password=xxxxx
spring.data.cassandra.session-name=xxxxxx

3、config

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.cassandra.config.AbstractCassandraConfiguration;
import org.springframework.data.cassandra.config.CqlSessionFactoryBean;

@Configuration
public class CassandraConfig extends AbstractCassandraConfiguration {


    @Value("${spring.data.cassandra.keyspace-name}")
    private String keyspaceName;

    @Value("${spring.data.cassandra.contact-points}")
    private String contactPoints;

    @Value("${spring.data.cassandra.username}")
    private String username;

    @Value("${spring.data.cassandra.password}")
    private String password;

    @Value("${spring.data.cassandra.session-name}")
    private String sessionName;

    @Value("${spring.data.cassandra.port}")
    private int port;

    @Override
    public String getKeyspaceName() {
        return keyspaceName;
    }

    @Override
    public String getContactPoints() {
        return contactPoints;
    }

    @Override
    public String getSessionName() {
        return sessionName;
    }

    @Override
    public String getLocalDataCenter() {
        return "dc-qcsh";
    }

    @Override
    public CqlSessionFactoryBean cassandraSession() {
        CqlSessionFactoryBean cqlSessionFactoryBean = super.cassandraSession();
        cqlSessionFactoryBean.setPassword(password);
        cqlSessionFactoryBean.setUsername(username);
        cqlSessionFactoryBean.setPort(port);
        cqlSessionFactoryBean.setKeyspaceName(keyspaceName);
        cqlSessionFactoryBean.setContactPoints(contactPoints);
        return cqlSessionFactoryBean;
    }

}

4、使用

@Resource
private CassandraTemplate cassandraTemplate;

// 批量插入
public void insert(){
    CassandraBatchOperations batchOps = cassandraTemplate.batchOps();
    batchOps.insert(List<entity>);
    batchOps.execute();
}
