com.imooc.o2o.dao.AreaDao这个接口是不是没定义？错误报的是这个 请仔细检查

• 提问者 慕仔0506944 #1

  那个没有错，是pom.xml的配置出错了

• 翔仔 回复 提问者 慕仔0506944 #2

  从异常信息确实是说当时的类加载器加载不到对已给你的AreaDao造成的，应该不会是pom.xml没有配置导致的异常，程序说1是1，不会骗人，所以可能是其他问题联动导致出现的这个问题，需要多总结

• 提问者 慕仔0506944 回复 翔仔 #3

  但是我是在，重写pom.xml文件之后，报错就消失了，并且在之前的验证都是对的，那是不是可以说是，因为在service这层的配置没对，导致无法加载到AreaDao导致的
