theme/overrides/MuiButton.js

import palette from '../palette';

export default {
  contained: {
    backgroundColor: '#FFFFFF',

      },
    },
  },
};

theme/overrides/index.js

import MuiButton from "./MuiButton";

export default {
  MuiButton
};

theme/index.js

import { createMuiTheme } from "@material-ui/core";

import palette from "./palette";
import typography from "./typography";
import overrides from "./overrides";

const theme = createMuiTheme({
  palette,
  typography,
  overrides,
  zIndex: {
    appBar: 1200,
    drawer: 1100
  }
});

export default theme;

确定如何适当地覆盖主题中的默认样式的最佳资源是查看默认样式的定义方式。

来自https://github.com/mui-org/material-ui/blob/v4.11.0/packages/material-ui/src/Button/Button.js#L138：

  containedPrimary: {
    color: theme.palette.primary.contrastText,
    backgroundColor: theme.palette.primary.main,
    '&:hover': {
      backgroundColor: theme.palette.primary.dark,
      // Reset on touch devices, it doesn't add specificity
      '@media (hover: none)': {
        backgroundColor: theme.palette.primary.main,
      },
    },
  },

将此方法转换为您问题中的代码如下所示：

import palette from '../palette';

export default {
  containedPrimary: {
    backgroundColor: '#FFFFFF',
    '&:hover': {
      backgroundColor: palette.primary.dark,
    },
  },
};
