错误信息:Caused by: org.hibernate.boot.MappingException: Unable to perform unmarshalling at line number 14 and column 87. Message: cvc-pattern-valid: 对于类型为 ‘ClassNameType’ 的模式 ‘([a-zA-Z_KaTeX parse error: Undefined control sequence: \d at position 9: ][a-zA-Z\̲d̲_].)[a-zA-Z_KaTeX parse error: Undefined control sequence: \d at position 9: ][a-zA-Z\̲d̲_]*’, 值 'com.atguigu.hibernate.tow_way.Customer ’ 不具有面有效性。 :

原因如图所示
出现这个异常,可能是hibernate的.hbm.xml映射配置文件里属性名或者字段名有错,或者是忘记标签后面加""了,在英文双引号下,不能多余任何字符,即使你不注意看到的空格都不能加进去

检查.hbm.xml文件
果然去掉里面的空格异常消失
