Spring自定义类型转换规则

@Bean
public class DateConvert implements Converter<String, Date> {

    @Override
    public Date convert(String stringDate) {
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd");
        try {
            return simpleDateFormat.parse(stringDate);
        } catch (ParseException e) {
            e.printStackTrace();
        }
        return null;
    }

}
