配置Mybatis遇到的问题 org.apache.ibatis.exceptions.PersistenceException: ### Error building SqlSession. ### The error may exist in com.smbms.dao.UserMapper.xml ### Cause: org.apache.ibatis.builder.BuilderException: Error parsing SQL Mapper Configuration. Cause: java.io.IOException: Could not find resource com.smbms.dao.UserMapper.xml at org.apache.ibatis.exceptions.ExceptionFactory.wrapException(ExceptionFactory.java:30) 这个显然是mapper.xml文件配置出了问题。 我解决的方法是， 修改分隔符（将.换成\） 来源： CSDN 作者： halla001 链接： https://blog.csdn.net/DaDaguai001/article/details/104105577

在项目根目录下创建 .eslintrc.js 文件，并添加如下代码： module . exports = { root : true , env : { node : true } , 'extends' : [ 'plugin:vue/essential' , 'eslint:recommended' ] , rules : { 'no-console' : process . env . NODE_ENV === 'production' ? 'error' : 'off' , // 'no-debugger': process.env.NODE_ENV === 'production' ? 'error' : 'off' } , parserOptions : { parser : 'babel-eslint' } } 如图所示： 来源： CSDN 作者： weixin_42934172 链接： https://blog.csdn.net/weixin_42934172/article/details/104100989

本题要求实现链式表的操作集。 函数接口定义： Position Find( List L, ElementType X ); List Insert( List L, ElementType X, Position P ); List Delete( List L, Position P ); 其中 List 结构定义如下： typedef struct LNode *PtrToLNode; struct LNode { ElementType Data; PtrToLNode Next; }; typedef PtrToLNode Position; typedef PtrToLNode List; 各个操作函数的定义为： Position Find( List L, ElementType X ) ：返回线性表中首次出现X的位置。若找不到则返回ERROR； List Insert( List L, ElementType X, Position P ) ：将X插入在位置P指向的结点之前，返回链表的表头。如果参数P指向非法位置，则打印“Wrong Position for Insertion”，返回ERROR； List Delete( List L, Position P ) ：将位置P的元素删除并返回链表的表头。若参数P指向非法位置，则打印“Wrong Position
