做单元测试的时候报了java.lang.IllegalStateException: Failed to load AplicationContex的错误

Question

老师，我在做单元测试的时候报了java.lang.IllegalStateException: Failed to load AplicationContex的错误
我知道是xml文件错了，但是配置xml的文件那么多，怎么才能定位到出问题的那一个呢，我感觉这是新手都会存在的问题，xml文件太多，基础知识不够，很难分清各自的具体分工

老师，我按照您说的检查了spring-dao和mybatis-config.xml文件的内容，按照您的视频核对了几遍，并且classpath也是按照您的视频设置的，我把图贴了出来，另外按照您说的第三条改成classpath*也试了，都是不行，实在找不到原因了

  可以了老师，我后来把您写的直接复制过来，就好了，还是我写的有问题，我找找是哪里写错了，感谢您的耐心指导

老师这是我的目录结构

同学好，xml并不多，可能语气有点重，但是请理解这是对你的期望。这我理解并不能用新手来作为推辞，谁都是从新手进来的，也都得通过自己努力来理解透彻。课程里的xml分得已经算是很清晰了，根据三层结构，

controller - spring-web.xml    

service- spring-service.xml  

dao-  spring-dao.xml

log - logback.xml

mybatis -   mybatis-config.xml

都是一一对应的，写在一起才混乱。

同学可以看看你这里

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [spring/spring-dao.xml]: Invocation of init method failed; nested exception is java.io.FileNotFoundException: class path resource [classspath:mybatis-config.xml] cannot be opened because it does not exist

异常已经非常清晰指出spring/spring-dao.xml这个文件里有错，错误是因为mybatis-config.xml  这个视频里创建起来的mybatis配置文件并没有存在，但是你却去读取了。。

所以耐心看看异常 看看caused by的信息，其实很多问题就能解决了，所以遇到问题不要心急，要尝试去定位去解决，这才能体现出我们的价值，我们的天命本来就是要解决问题，如果总看问题望洋兴叹，那我们做这行就失去竞争力了，所以一定要沉得住气，要学会快速成长，要认真学习并理解，而不是黑盒去敲代码编程

  老师但是我检查了我的文件结构，里面是有mybatis-config.xml这个文件的，依然显示有这个错误，这地方我就搞不明白了

• 提问者 慕后端9028910 #2

  而且我按照网上的检查了编译目录，发现mybatis-config.xml是存在的

• 翔仔 回复 提问者 慕后端9028910 #3

  程序说1是1，不可能骗同学的，这个异常就说的是这个文件不存在，同学可以提供文件目录截图出来，或者和视频对比一下mybatis-config.xml的存放位置，绝对没在classpath下面，或者是eclipse的tomcat没有clean，缓存没是最新的
