将此代码放在您的css文件中，该文件位于antd css文件之后：

.ant-menu-submenu > .ant-menu-submenu-title .ant-menu-submenu-arrow::before {
  content: '';
  position: absolute;
  background: unset !important;
  background-image: unset !important;
  width: 0 !important;
  height: 0 !important;
  border-style: solid;
  border-width: 6px 0 6px 6px;
  border-color: #00d2be transparent transparent transparent;
  transition: transform 0.3s ease-in-out !important;
  transform: rotate(45deg) !important;
  border-radius: 0 !important;
  left: 0;
  top: 50%;
}

.ant-menu-submenu-open > .ant-menu-submenu-title .ant-menu-submenu-arrow::before {
  content: '';
  position: absolute;
  background: unset !important;
  background-image: unset !important;
  width: 0 !important;
  height: 0 !important;
  border-style: solid;
  border-width: 6px 0 6px 6px;
  border-color: #00d2be transparent transparent transparent;
  transition: transform 0.3s ease-in-out !important;
  transform: rotate(-45deg) !important;
  border-radius: 0 !important;
  left: 0;
  top: 50%;
}

.ant-menu-submenu-inline > .ant-menu-submenu-title .ant-menu-submenu-arrow::after,
.ant-menu-submenu-vertical-left > .ant-menu-submenu-title .ant-menu-submenu-arrow::after,
.ant-menu-submenu-vertical-right > .ant-menu-submenu-title .ant-menu-submenu-arrow::after,

不确定这是否为时已晚，尽管我看到一条评论，询问是否找到了解决方案。如果使用菜单组件的“expandIcon”参数，您可以将自己的自定义图标传递到子菜单组件中：

 <Menu
        expandIcon={<YourCustomIcon/>}
        selectedKeys={current}
        mode="inline"
    >
        <SubMenu style={{ width: 150 }} key="sub1">
            <Menu.Item key="1">Option 1</Menu.Item>
            <Menu.Item key="2">Option 2</Menu.Item>
            <Menu.Item key="3">Option 3</Menu.Item>
            <Menu.Item key="4">Option 4</Menu.Item>
        </SubMenu>
    </Menu>
