【解决方案1】：

这是不同spring版本之间的版本冲突问题。将spring-framework-bom 依赖项添加到您的dependencyManagement 部分将为您解决问题：

<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-framework-bom</artifactId>
                <version>${springframework.version}</version>
                <scope>import</scope>
                <type>pom</type>
            </dependency>
        </dependencies>
</dependencyManagement>

基本上，spring-data-mongodb:1.8.4.RELEASE 依赖于 spring 框架 4.1.9.RELEASE 并且您正在使用框架的 4.2.4.RELEASE 版本。使用您当前的pom.xml，您将拥有两全其美的体验。添加spring-framework-bom 确保您将使用正确版本的spring 框架。

忠告，如果您不需要库，请不要将其依赖项添加到您的项目中。您不太可能真的需要CGLIB。
