java Duration.parse(String str)格式，以及springboot@ConfigurationProperties对其完善优化

总结：图

Duration.parse()只接受的格式基于ISO-8601持续时间格式PnDTnHnMn.nS

springboot@ConfigurationProperties支持更多的格式

@Data
@Component
@ConfigurationProperties(prefix = "my")
public class MyProperties {
    Duration nanos;
    Duration millis;
    Duration seconds;
    Duration minutes;
    Duration hour;
    Duration day;
}

@Slf4j
@RestController
public class MyController {
    @Autowired
    private MyProperties myProps;

    @GetMapping("prop")
    void prop() {
        // 接受的格式基于ISO-8601持续时间格式PnDTnHnMn.nS ，其中几天被认为是24小时。
        log.info("{}",myProps);
        log.info("{}",myProps.nanos.toNanos());
//        log.info("{}",Duration.parse("PT1ns"));  // 不支持
        log.info("{}",myProps.millis.toNanos());
//        log.info("{}",Duration.parse("PT1ms"));  // 不支持
        log.info("{}",myProps.seconds.toNanos());
        log.info("{}",Duration.parse("PT1.0s").toNanos() + "\t\t\t" + Duration.parse("PT1.0s"));
        log.info("{}",myProps.minutes.toNanos());
        log.info("{}",Duration.parse("PT1m").toNanos() + "\t\t\t" + Duration.parse("PT1m"));
        log.info("{}",myProps.hour.toNanos());
        log.info("{}",Duration.parse("PT1h").toNanos() + "\t\t\t" + Duration.parse("PT1h"));
        log.info("{}",myProps.day.toNanos());
        log.info("{}",Duration.parse("P1D").toNanos() + "\t\t\t" + Duration.parse("P1D"));
    }
}
