    class DemoForm extends React.Component {
        render() {
            const {getFieldDecorator} = this.props.form;
            const {intl} = this.props;
            const placeholder = intl.formatMessage({id:'enterHere'});

            return (
                 <Form.Item label={<FormattedMessage id='name'/>}>
                  {getFieldDecorator('name',)(<Input placeholder={placeholder}/>)}
                 </Form.Item>
            )
       }
}
export const Demo = injectIntl(Form.create()(DemoForm));

Use this Demo class for show your component.
