Spring Data Mongodb 2.0.2 CustomConversions NoClassDefFoundError

Question

我想使用 Spring Data Mongodb。问题是，当我将 Spring Data Mongodb 版本从 1.10.9.RELEASE 更改为 2.0.2.RELEASE 时，编译时会出现问题：

这个问题在使用 Spring Data Mongodb 1.xy 时没有出现，目前我已经用 spring boot 1.5.9.RELEASE 引导了项目。

Answer 1

Spring Data 2.x 似乎与 Spring Boot 1.x 不兼容。根据这个问题：

NoSuchMethodError：org.springframework.data.repository.config.RepositoryConfigurationSource.getAttribute

因此，如果不升级到 Spring boot 2，则无法使用 Spring data Mongodb 2.x 或 Spring Data Neo4J 5.x
