Question

使用当前的GA 1.2.1版时，我遇到以下异常。存储库对象在我的示例代码中自动装配。

是否有针对此的修复或解决方法？

Answer 1

经过多次窥探我发现问题是由于使用了旧版本的spring-cql。

我通过使用依赖关系管理来明确使用最新的spring-cql版本来修复它。将其添加到您的pom.xml：

<dependencyManagement>
      <dependencies>
    <dependency>
          <groupId>org.springframework.data</groupId>
          <artifactId>spring-cql</artifactId>
          <version>1.2.1.RELEASE</version>
    </dependency>
      </dependencies>
    </dependencyManagement>

Answer 2

spring-data-cassandra 1.1.3版本没有这个问题。如果你只是需要让事情运转，你可以切换回来。

（我也在看这个问题，看它是否得到修复。）

ClassNotFoundException：org.springframework.cassandra.core.Cancellable with spring-data-cassandra version 1.2.1
