java - Mockito 不起作用 MockitoSessionLogger DefFoundError

Question

我在 Spring 项目中的测试工作得很好，直到我做了一些事情，在我的 WebMvcTest 中，MockMvc 开始只是 null。在我需要模拟我的存储库的服务测试中，会抛出此异常:

我建议添加 mockito-core 依赖项 ( https://mvnrepository.com/artifact/org.mockito/mockito-core )。

<dependency>
    <groupId>org.mockito</groupId>
    <artifactId>mockito-core</artifactId>
    <version>3.7.0</version>
    <scope>test</scope>
</dependency>

另一个答案中提到的 mockito-all 依赖项上次更新于 2015 年。
