上面代码的github网址是github link

Answer 1

这是由于在测试运行时类路径中混合使用不同版本的Log4J引起的。 Spring Boot拉入2.10.0，你的build.gradle声明为2.6.2。

如果从依赖关系定义中删除版本，Spring Boot将定义版本并且它将起作用。

所以，请替换这两行

testRuntime("org.apache.logging.log4j:log4j-core:${log4jVersion}")
testRuntime("org.apache.logging.log4j:log4j-jul:${log4jVersion}")

用这些：

testRuntime("org.apache.logging.log4j:log4j-core")
testRuntime("org.apache.logging.log4j:log4j-jul")

或者，您可以从logManager扩展名中删除junitPlatform属性并删除这两个依赖项。

将JUnit5与spring boot 2一起使用时出错
