React写class组件时遇到如下警告

配置装饰器解决experimentalDecorators警告问题

Experimental support for decorators is a feature that is subject to change in a future release. Set the 'experimentalDecorators' option in your 'tsconfig' or 'jsconfig' to remove this warning.

解决方法：

1.在vscode设置中配置

勾选

2.在项目根目录新建jsconfig.json，添加代码

{

  "compilerOptions": {

    "experimentalDecorators": true

  }

}

重启项目就可以了
