我Google了一些，尝试添加依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <version>1.5.2.RELEASE</version>
</dependency>

但并没有用。

nested exception is java.lang.NoClassDefFoundError

应该是版本不对，导致找不到类，保持和我的源码一样的版本。

  老师，我的jdk版本就是1.8..  只是我的Test跑不起来

• 提问者 Nnn_Lillian #2

  不只是LoggerTest跑不起来，本身自带的Test也跑不起来。

  跑起来了吗？
