cmd命令窗口运行脚本ModuleNotFoundError: No module named 'requests'

原来的：<?xml version="1.0" encoding="UTF-8"?><mapper namespace=""></mapper>报错信息(主要的)：columnNumber: 22; 文档根元素 "mapper" 必须匹配 DOCTYPE 根 "null"修改xml：<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE mapper PUBLIC "-//my

下面是报错内容org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.multipart.MultipartFile]: Specified class is an interface直接看Controller类：package com.tjcu.controller;import org.apache.commons.io.Filena.

这个问题刚开始会很常见，经常忘记在写路径的地方加上classpath: <!--数据源--> <context:property-placeholder location="classpath:pro.properties"/> <bean class="com.alibaba.druid.pool.DruidDataSource" id="dataSource"> <property name="driverClass.

学习了springmvc后 就想在maven-webapp项目中用spring+springmvc+mybatis整合做一个网页现有entity+vo+dao+service+controller起初 我把spring.xml 和springmvc.xml两个文件分开写 并且同时加了注解扫描，放置在resources根目录下spring.xml扫描的是com.tjcu.servicespringmvc.xml扫描的是com.tjcu.controller 只有service层的实现类和con.

错误代码： <sql id="SELECT_SCGC"> select s.s_id as s_id , s.s_name as s_name , s.s_phone as s_phone , s.s_qq as s_qq , s.s_age as s_age , s.s_birthday as s_birthday , s.s_starts as s_starts , s.s_attr as s_attr, .
