如果有人能找出这一错误的根本原因，我们将不胜感激

Well

com.github.springtestdbunit

依赖版本

1.0.0

需要（已在其pom中定义-请参阅相关github页面）：

3.0.5.发布

但是，

org.springframework.boot

依赖版本

1.3.2.发行版

要求：

4.2.4.发布

因此，您的应用程序中有两个不同的spring版本

为了兼容，您可以将

com.github.springtestdbunit

升级到

1.2.1

版本，这是最新版本，需要spring

4.1.4.RELEASE

（），并将

org.springframework.boot

版本降级到

1.2.1.RELEASE

，该版本也使用spring

4.1.4.RELEASE

（）


org.springframework.boot
spring启动程序父级
1.2.1.发布
com.github.springtestdbunit
弹簧试验装置
1.2.1

几乎总是意味着您的版本不匹配。发布您的POM或Gradle构建文件。请注意，该教程已经有三年的历史了，您可以在@chrylis自动生成一个骨架项目。我已经添加了pom.xml，谢谢。不需要降级到Spring Boot 1.2.1。Spring4.2.x与4.1.x向后兼容，因此仅升级SpringTestDBUnit就足够了。
