Question

我试图通过使用java中的spring数据从mongoDB中删除文档

这是我的maven dependecies：

<parent>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-parent</artifactId>
    <version>Brixton.SR1</version>
    <relativePath/>
</parent>
<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>

我使用MongoRepository在java中定义我的存储库：

public interface FilesInfoRepository extends MongoRepository<MyCollectionClass, String> { ... }

这是一个简短的例外：

**java.lang.NoClassDefFoundError: com/mongodb/RemoveRequest**

以下是完整的例外情况：

 ERROR [[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Handler processing failed; nested exception is java.lang.NoClassDefFoundError: com/mongodb/RemoveRequest] with root cause java.lang.NoClassDefFoundError: com/mongodb/RemoveRequest

我的mongo是一个replicaSet，是另一个数据中心，但我确信连接运行良好，mongo上的其他操作运行良好，只是删除不起作用。
