我对简单的spring引导应用程序有问题。我正在使用:
spring boot starter父级
Spring启动机数据cassandra
cassandra 3.11.3(在centos 7服务器和本地mac os上)(由cqlsh works查询)
我遵循了一个简单的指南https://www.baeldung.com/spring-data-cassandra-tutorial 不管cassandra是在运行还是不运行,我在启动时都会得到一个错误:
2018-11-25 09:12:34.581 ERROR 83213 --- [main] o.s.boot.SpringApplication: Application run failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'session' defined in class path resource [some/project/path/CassandraConfig.class]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: com/codahale/metrics/JmxReporte
我的配置类:
@Configuration
@EnableCassandraRepositories(basePackages = "packagename")
public class CassandraConfig extends AbstractCassandraConfiguration {
@Override
protected String getKeyspaceName() {
return "test";
}
@Bean
public CassandraClusterFactoryBean cluster() {
CassandraClusterFactoryBean cluster = new CassandraClusterFactoryBean();
cluster.setContactPoints("127.0.0.1");
cluster.setPort(9042);
return cluster;
}
@Override
public SchemaAction getSchemaAction() {
return SchemaAction.CREATE_IF_NOT_EXISTS;
}
@Override
public String[] getEntityBasePackages() {
return new String[]{"packagename"};
}
}
实体:
@Table
public class Image implements Serializable {
@PrimaryKeyColumn(
name = "key",
ordinal = 0,
type = PrimaryKeyType.PARTITIONED)
private UUID id;
@Column
private Blob object;
}
存储库:
@Repository
public interface ImagesRepository extends CrudRepository<Image, UUID> {
}
Cassandra结构:
CREATE TABLE images (
key text,
object blob,
PRIMARY KEY (key)
);
也https://github.com/springframeworkguru/spring-boot-cassandra-example 在创建bean时也给了我一个错误。

缺少dropwizard依赖项:
您需要度量核心库作为依赖项:
笔记
确保在pom中声明了metrics.version属性,当前版本为3.1.0。
