java Spring应用程序在jar中构建后不工作

1 月 Questions & Answers 319

我有一个简单的Spring应用程序：

主要类别：

@SpringBootApplication
@EnableScheduling
public class SchedulerApplication {

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

为预定的工作安排课程

@Component
public class Executor {

    private static final Logger log = LoggerFactory.getLogger(Executor.class);
    private Integer jobCounter = 1;

    @Scheduled(fixedDelay = 1000)
    public void run() {
        log.info("Start task (" + jobCounter + ")");
        log.info("Stop task");
        jobCounter ++;
    }
}

这是波姆。xml

这就是我的项目结构

它在IDE（IntelliJ IDEA）下运行良好，但当我将此代码编译到jar文件并运行时：

java -jar scheduler.jar

我有一大堆这样的错误

组织。springframework。豆。工厂BeanDefinitionStoreException:无法处理配置类[ru.alexeyzhulin.SchedulerApplication]的导入候选项；嵌套的异常是java。lang.IllegalArgumentException:在META-INF/spring中找不到自动配置类。f工厂。如果您使用的是自定义打包，请确保该文件正确无误

我错过了什么
