我安装了
Spring Boot,使用Gradle来管理我的依赖项.

显示的错误是：

:test

com.chefinator.ChefinatorApplicationTests > contextLoads FAILED
    java.lang.IllegalStateException
        Caused by: java.lang.IllegalStateException
            Caused by: java.lang.NoClassDefFoundError
                Caused by: java.lang.ClassNotFoundException

1 test completed, 1 failed
:test FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':test'.

在我不得不将Spring Framework JDBC依赖项添加到build.gradle文件之前,此错误从未开始.

compile('org.springframework:spring-jdbc:4.2.2.RELEASE')

当我删除JDBC依赖项时,测试会神奇地再次开始构建而没有任何错误.

错误跟踪如下：

我真的很难解决问题所在,它正在推动我的问题.我需要依赖,但它不想出于某种原因合作.

有没有人有任何想法？谢谢！

最佳答案 只添加JDBC jar会弹出启动以开始尝试执行其他配置(这需要更多的jar – 在本例中为EventListenerFactory.您应该包含jdbc启动程序以确保获得自动配置所需的所有依赖项：

compile('org.springframework.boot:spring-boot-starter-jdbc:1.2.7.RELEASE')

将1.2.7替换为您正在使用的任何弹簧靴版本.
