Question

我的Spring-boot应用程序运行良好，直到我开始摆弄弹簧靴和黄瓜测试。不能确切地说出了什么问题但是从我的研究来看，我pom.xml

中的库依赖性不匹配

您可以安全地删除此依赖项：

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-tx</artifactId>
    <scope>test</scope>
</dependency>

通过 spring-boot-starter-data-jpa 您已经具有对 spring-tx 的传递依赖性。

通过将 spring-tx 显式绑定到测试范围，将其从编译范围（mavens默认范围）中删除< / p>
