1. 配置文件tsconfig.json的paths属性

"paths": {
        "@components/*": ["src/components/*"],
        "@assets/*": ["src/assets/*"], // css, html中需要 `~@assets/*`
    }

2. config/index.js的alias属性

alias: {
    '@components': path.resolve(__dirname, '..', 'src/components'),
　 '@assets': path.resolve(__dirname, '..', 'src/assets'),
