    }
}

在调度程序方法中，我尝试使用my.delay：

@SpringBootApplication
@EnableScheduling
@EnableConfigurationProperties( { MyProperties.class } )
public class TestSprPropApplication {

    public static void main(String[] args) {
        SpringApplication.run(TestSprPropApplication.class, args);
    }

    @Scheduled( fixedDelayString = "${my.delay}" )
    public void schedule() {
        System.out.println( "scheduled" );
    }
}

然后出现以下错误：
