@Slf4j
@RestController
public class EnvController {@Value("${controlFlag}")private String controlFlag;//每天定时6点启动任务@Scheduled(cron = "00 00 06 * * ?")public void taskScheduling() {if ("1".equals(this.controlFlag)) {log.info("任务调度获取的controlFlag状态位为,->{}" + this.controlFlag);}}@GetMapping("/env")public String env() {System.out.println("读取环境变量->controlFlag:" + this.controlFlag);if ("1".equals(this.controlFlag)) {return "环境变量controlFlag为" + this.controlFlag;} else {return "环境变量controlFlag为" + this.controlFlag;}}
}
