antd design pro修改tree展开/折叠图标

.less文件

:global{
    .ant-tree-switcher_close{
        background: url('../../assets/browse/down.png') no-repeat;
    }
    .ant-tree-switcher_open{
        background: url('../../assets/browse/up.png') no-repeat;
    }
}

.js文件引用less，该页面所有的Tree的图标都改了

import styles from './**.css';

Tree的子组件TreeNode加上 switcherIcon={() => null}，去掉Tree的默认图标

<TreeNode
	...
	switcherIcon={() => null}
/>
