我正在使用Spring-Data-Cassandra（1.5.RC1）和Cassandra 3.x构建SpringBoot应用程序
现在，这是我的CassandraConfig课程：
@Configuration
@PropertySource(value = { "classpath:META-INF/cassandra.properties" })
@EnableCassandraRepositories(basePackages = { "com.rg" })
public class CassandraConfig {
@Autowired
private Environment environment;
private static final Logger LOGGER = LoggerFactory.getLogger(CassandraConfig.class);
@Bean
public CassandraClusterFactoryBean XCluster() {
CassandraClusterFactoryBean cluster = new CassandraClusterFactoryBean();
cluster.setContactPoints(environment.getProperty("cassandra.X.contactpoints"));
cluster.setPort(Integer.parseInt(environment.getProperty("cassandra.X.port")));
return cluster;
}
@Bean
public CassandraMappingContext XMappingContext() {
return new BasicCassandraMappingContext();
}
@Bean
public CassandraConverter XConverter() {
return new MappingCassandraConverter(XMappingContext());
}
@Bean
public CassandraSessionFactoryBean XSession() throws Exception {
CassandraSessionFactoryBean session = new CassandraSessionFactoryBean();
session.setCluster(XCluster().getObject());
session.setKeyspaceName(environment.getProperty("cassandra.X.keyspace"));
session.setConverter(XConverter());
session.setSchemaAction(SchemaAction.NONE);
return session;
}
@Bean
public CassandraOperations XCassandraTemplate() throws Exception {
return new CassandraTemplate(XSession().getObject());
}
@Bean
public CassandraClusterFactoryBean orgCluster() {
CassandraClusterFactoryBean cluster = new CassandraClusterFactoryBean();
cluster.setContactPoints(environment.getProperty("cassandra.org.contactpoints"));
cluster.setPort(Integer.parseInt(environment.getProperty("cassandra.org.port")));
return cluster;
}
@Bean
public CassandraMappingContext orgMappingContext() {
return new BasicCassandraMappingContext();
}
@Bean
public CassandraConverter orgConverter() {
return new MappingCassandraConverter(activityMappingContext());
}
@Bean
public CassandraSessionFactoryBean orgSession() throws Exception {
CassandraSessionFactoryBean session = new CassandraSessionFactoryBean();
session.setCluster(activityCluster().getObject());
session.setKeyspaceName(environment.getProperty("cassandra.org.keyspace"));
session.setConverter(activityConverter());
session.setSchemaAction(SchemaAction.NONE);
return session;
}
@Bean
public CassandraOperations orgCassandraTemplate() throws Exception {
return new CassandraTemplate(orgSession().getObject());
}
}
这是我的存储库：
public interface ActivityRepository extends CassandraRepository<Activity> {
@Query("SELECT * FROM activities2 WHERE actor_id=?0")
Iterable<Activity> findByActor_Id(String actor_Id);
// @Query("SELECT * FROM activities2 WHERE viewer_id='?0'")
// Iterable<Activity> findByApp_Id(String appId);
}
但是，该应用无法加载，并显示以下错误：

我没有强调如果没有我在代码中明确声明，将项目的先前版本中的cassandraTemplate如何自动装入应用程序。如果我能理解我可以摆脱这个错误。任何线索？
答案 0 :(得分：0)
您可以使用以下代码作为示例：
@Configuration
public class CassandraConfig {
@Bean
public CassandraClusterFactoryBean cluster() {
CassandraClusterFactoryBean cluster = new CassandraClusterFactoryBean();
cluster.setContactPoints(cassandraContactPoints);
cluster.setPort(Integer.parseInt(cassandraPort));
return cluster;
}
@Bean
public CassandraMappingContext mappingContext() {
return new BasicCassandraMappingContext();
}
@Bean
public CassandraConverter converter() {
return new MappingCassandraConverter(mappingContext());
}
@Bean
public CassandraSessionFactoryBean session() throws Exception {
CassandraSessionFactoryBean session = new CassandraSessionFactoryBean();
session.setCluster(cluster().getObject());
session.setKeyspaceName(cassandraKeyspace);
session.setConverter(converter());
session.setSchemaAction(SchemaAction.NONE);
return session;
}
@Bean
public CassandraOperations cassandraTemplate() throws Exception {
return new CassandraTemplate(session().getObject());
}
}
