Question

我使用最新版本的spring-data-cassandra，它是2.0.0.RELEASE和最新版本的spring-boot-starter-web - 1.5.7.RELEASE

Resources:
  DnsRedis:
    Type: 'AWS::Route53::RecordSetGroup'
    Properties:
      HostedZoneName: 'a.hosted.zone.name.'
      RecordSets:
        - Name: 'a.record.set.name'
          Type: CNAME
          TTL: '300'
          ResourceRecords:
            - !GetAtt
              - RedisCacheCluster
              - RedisEndpoint.Address  
    DependsOn: RedisCacheCluster

  RedisCacheCluster:
    Type: 'AWS::ElastiCache::CacheCluster'
    Properties:
      ClusterName: cluster-name-redis
      AutoMinorVersionUpgrade: 'true'
      AZMode: single-az
      CacheNodeType: cache.t2.small
      Engine: redis
      EngineVersion: 3.2.4
      NumCacheNodes: 1
      CacheSubnetGroupName: !Ref ElastiCacheSubnetGroupId
      VpcSecurityGroupIds:
        - !GetAtt
          - elasticacheSecGrp
          - GroupId

我可以毫无问题地构建项目，但是应用程序不会以以下异常开始：

  <dependencies>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-cassandra</artifactId>
        <version>2.0.0.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <version>1.5.7.RELEASE</version>
    </dependency>
</dependencies>

根本原因：

看起来问题出在spring-boot-autoconfigure-1.5.7.RELEASE中，如果我将spring-boot-starter-web更新为2.0.0.M5：

Caused by: java.lang.ClassNotFoundException: org.springframework.data.cassandra.mapping.CassandraMappingContext

然后应用程序启动没有任何错误。

有没有办法使用spring-data-cassandra的最新版本以及spring-boot-starter-web，还是应该等待spring-boot-starter-web的GA：2.0.0？

提前谢谢！

Answer 1

最新版本的Spring Data Cassandra是2.0.0，它与Spring Boot 1.x不兼容。您需要将依赖项升级到Spring Boot 2.0 M5。

Answer 2

嗨，我遇到了同样的问题，所以在这里我做了什么，首先，我在cassandra中连接多个键空间，并使用带有 Spring Boot Starter 2.0.0。发布我删除了spring数据cassandra的版本声明，但是其托管版本为2.0.5.RELEASE，因此您可以进行检查。第二我在org.springframework.data.cassandra.config.java.AbstractCassandraConfiguration时出错是在2.0.0.RELEASE之前和之内导入的，已移至 org.springframework.data.cassandra.config.AbstractCassandraConfiguration 所以一定要检查一下

spring-data-cassandra-2.0.0.RELEASE + spring-boot-starter-web-1.5.7.RELEASE导致java.lang.ClassNotFoundException
