1.下拉列表框的数据回显，二级分类是遍历出来的，回显后没有数据
修改侧边栏的默认显示还是隐藏
/找到store/modules/app.js文件
const app = {
state: {
sidebar: {
// opened: !+Cookies.get('sidebarStatus'), //原值
opened:true, //默认展开（false是隐藏）
withoutAnimation: false
},
device: 'desktop',
language: Cookies.get('language') || 'en',
size: Cookies.get('size') || 'medium'
},
mutations: {
TOGGLE_SIDEBAR: state => { //点击收缩功能触发
// if (state.sidebar.opened) {
// Cookies.set('sidebarStatus', 1)
// } else {
// Cookies.set('sidebarStatus', 0)
// }
// state.sidebar.opened = !state.sidebar.opened
state.sidebar.opened = true
state.sidebar.withoutAnimation = false
},
CLOSE_SIDEBAR: (state, withoutAnimation) => { //自适应触发
Cookies.set('sidebarStatus',1)
state.sidebar.opened = true
state.sidebar.withoutAnimation = withoutAnimation
}
}
2.'MP_OPTLOCK_VERSION_ORIGINAL' not found
报错
Caused by: org.apache.ibatis.binding.BindingException: Parameter 'MP_OPTLOCK_VERSION_ORIGINAL' not found. Available parameters are [param1, et]
解决:乐观锁OptimisticLockerInterceptor 已经被废弃，可以在 MybatisPlusInterceptor 拦截器对象中加入新版的 OptimisticLockerInnerInterceptor 乐观锁对象，interceptor.addInnerInterceptor(new OptimisticLockerInnerInterceptor());3.3.0之后的 mybatis-plus 要这样使用
//乐观锁插件
@Bean
public MybatisPlusInterceptor optimisticLockerInnerInterceptor(){
MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
interceptor.addInnerInterceptor(new OptimisticLockerInnerInterceptor());
return interceptor;
//return new OptimisticLockerInnerInterceptor();
}
3.jar包依赖冲突
找到引起冲突的父类包,在其里面添加exclusions标签,这个方法排除了swagger jar包导致不能用
<!--swagger-->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>${swagger.version}</version>
<exclusions>
<exclusion>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
</exclusion>
</exclusions>
</dependency>
4.前端报错：无法加载文件 D:\NodeJS\node_global\babel.ps1，因为在此系统上禁止运行脚本
解决:
（1）以管理员身份运行vs code
（2）在终端执行：get-ExecutionPolicy，显示Restricted（表示状态是禁止的）
（3）在终端执行：set-ExecutionPolicy RemoteSigned
（4）在终端执行：get-ExecutionPolicy，显示RemoteSigned
5.解决前端代码语法校验,在vue.config.js里
lintOnSave: false,

在vue-element-admin模板中去掉tui-editor
1、修改package.json
删除包括tui-editor的1行
2、删除tui-editor相关文件
rm src/components/MarkdownEditor/index.vue
rm src/views/components-demo/markdown.vue
vi src/router/modules/components.js 删除@views/components-demo/markdown相关内容，如下所示：
{
path: 'markdown',
component: () => import('@[/views/components-demo/markdown'),](javascript:;)
name: 'MarkdownDemo',
meta: { title: 'Markdown' }
},
然后就好了
7.Invalid prop: type check failed for prop "image". Expected String with value "undefined", got Undefined
image类型错误转换成string就好了
8.前端页面接收不到上传文件后的返回值
[Vue warn]: Error in v-on handler: "TypeError: Cannot read property 'url' of undefined"
found in
把调用方法后面的括号去掉就好

12.nuxt项目打包后阿里云播放器错误：ReferenceError: Aliplayer is not defined
这是因为导入js文件的问题，打包后没有完全导入js文件
解决:
通过配置引入，在 【nuxt.config.js】文件中引入
module.exports = {
/*
** Headers of the page
*/
head: {
title: ' ',
meta: [
{ charset: 'utf-8' },
{ name: 'viewport', content: 'width=device-width, initial-scale=1' },
{ hid: 'keywords', name: 'keywords', content: ' ' },
{ hid: 'description', name: 'description', content: ' ' }
],
link: [
{ rel: 'icon', type: 'image/x-icon', href: '/favicon.ico' }
],
//就是这个位置！！！！！
script:[
{src: "https://g.alicdn.com/de/prismplayer/2.8.1/aliplayer-min.js", type:"text/javascript"}
]
},
