我正在使用Spring-boot-starter-parent让Spring管理我项目的所有依赖项，并且我正在使用Spring Data Cassandra和Spring数据JPA
Spring-boot-starter-parent的版本是1.2.8.RELEASE.Lately我将版本更新为1.3.1.RELEASE并开始面临Spring Data Cassandra的一个奇怪问题
mvn:eclipse:eclipse它说我必须使用@Table等注释实体，但这些实体是Spring数据JPA Spring数据Cassandra的实体我已用@Table等注释

Spring Data JPA配置：
@SpringBootApplication
@EnableJpaRepositories( repositoryFactoryBeanClass = GenericRepositoryFactoryBean.class )
@EntityScan("com.sarvint.domain")
@Import(CassandraConfig.class)
public class Application {
public static void main( String[] args ) throws Exception

SpringApplication.run(Application.class, args);

这是Spring Data Cassandra中的一个错误。您的类路径上有多个Spring Data模块。在这种情况下，Spring Data会尝试确定特定存储库所属的模块。 Spring Data Cassandra错过了一点来识别您的JPA实体User不属于Cassandra，因此Spring Data Cassandra尝试为您的UserRepository创建一个Repository实例。
如果启用DEBUG日志记录，您将看到一些DEBUG日志消息，指出Spring Data正在进入严格配置模式。
Spring Boot 1.3.0引入了Spring Data Cassandra存储库的自动配置。由于此更改，Spring Boot执行scan for Spring Data Cassandra repositories，就像您仅使用@EnableCassandraRepositories配置它一样。
只有使用多个Spring Data模块的默认EnableCassandraRepositories组合才会发现此错误。
在spring.data.cassandra.repositories.enabled=false设置application.properties以禁用自动配置，因为您自己使用@EnableCassandraRepositories(basePackages="com.sarvint.cassandra.domain")。
我创建了一个错误报告here，因此您可以根据需要跟踪进度。

尝试升级到HikariCP 2.4.4。它包含此修复：
issue 495: implemented iterator() method on custom FastList to support Tomcat
memory leak detection.
