目前学到4-5课，在用junit测试service层时，报错的日志信息没有输出到控制台和日志文件，ImageUtil工具类里的日志信息也没有任何输出，正常运行时控制台输出内容如下

本应打印出来的保存路径并没有出现。

不过在使用ImageUtil里的main方法测试时却能在控制台输出logger打印的日志。
logback.xml文件是直接复制了课件的内容，应该是没有问题

同学好，请问你这边异常情况下不打印日志，请问日志是如何记录错误并输出的呢？并且其实ut很多情况下并不需要打印日志呢，因为直接设置断点调试即可，现在关注点是项目真正执行的时候能否打印出日志，如果不行，并且是复制的课程日志配置的话，建议把jar包对齐一下，清除相关jar重新update maven project试试

同学好，catalina.base指向每个Tomcat目录私有信息的位置，需要设置，否则默认会生成这个文件夹，将你的项目发布到这里，而由于日志和项目是一起的，所以在这里生成。 https://blog.csdn.net/fk5431/article/details/50098003
