如何使用spring转换服务将字符串值从属性文件自动转换为其他数据类型，即持续时间？

@Configuration
@ConfigurationProperties(prefix = "myapp")
public class MyAppConfig {
    private Duration duration;

    public Duration getDuration() {
        return duration;
    }

    public void setDuration(Duration duration) {
        this.duration = duration;
    }
}

@Component
public class StringToDurationConverter implements Converter<String, Duration> {
    @Override
    public Duration convert(String source) {
        return Duration.parse(source);
    }
}

@Configuration
@ConfigurationProperties(prefix = "myapp")
public class MyAppConfig {
    // ...

    @Bean
    public ConversionService conversionService() {
        DefaultConversionService conversionService = new DefaultConversionService();
        conversionService.addConverter(new StringToDurationConverter());
        return conversionService;
    }
}

@Service
public class MyService {
    private final Duration duration;

    public MyService(MyAppConfig appConfig) {
        this.duration = appConfig.getDuration();
    }

    public void doSomething() {
        // 使用持续时间属性
        System.out.println("Duration: " + duration);
    }
}
