Springboot如何进行时间参数格式化呢?

字符串转换为Date的实现思路

@Configuration
public class DateTimeFormatConfiguration extends WebMvcConfigurerAdapter {

    @Value(value = "${spring.jackson.date-format:yyyy-MM-dd HH:mm:ss}")
    private String formatString;
    
    @Override
    public void addFormatters(FormatterRegistry registry) {
        registry.addConverter(new DateConvert());
    }
    
    public class DateConvert implements Converter<String, Date>{
        private SimpleDateFormat formatter= new SimpleDateFormat(formatString);

        @Override
        public Date convert(String s) {
            if(StringUtil.isNullOrEmpty(s)){
                return null;
            }
            try {
                Date date = formatter.parse(s);
                return date;
            } catch (ParseException e) {
                e.printStackTrace();
            }
            
            return null;
        }
        
    }
}
