我在 Spring Boot 的文档 (https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-logging.html) 中看到，你也可以在应用程序配置文件中指定 debug=true。
所以我猜如果我在 application.properties 中加上 debug=false 就能关闭调试日志。我尝试过了，但是没有起作用。接着我在同一篇文档中读到：
“日志系统会在应用生命周期的早期初始化，因此不会在通过 @PropertySource 注解加载的属性文件中找到日志属性。”
以及：
“由于日志在 ApplicationContext 创建之前就已初始化，因此无法从 Spring @Configuration 文件中的 @PropertySources 控制日志记录。”
还有：
“在可能的情况下，我们建议您使用 -spring 变量来配置日志记录。”因此，我在 src/main/resources 中添加了一个名为 log4j-spring.properties 的文件。
在这个文件中，我只添加了 debug=false 这一行，但是我仍然看到所有“当前日期”[main]DEBUG...信息。那么，我的问题是如何关闭 Spring Boot 应用程序中的调试消息，因为我将把应用程序部署到生产环境中。是否有一种推荐的方式通过 maven 实现呢？
2月12日添加：
两种主要方法： 1）使用 AnnotationConfigApplicationContext:
public class DemoAppNoBoot {
public static void main(String[] args) {
AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(
BatchConfiguration.class);
JobLauncher jobLauncher = (JobLauncher) context.getBean("jobLauncher");
Job job = (Job) context.getBean("job");
try {
JobExecution execution = jobLauncher.run(job, new JobParameters());
} catch (Exception e) {
e.printStackTrace();
}
}
}
片段输出：

slf4j-api-1.7.13.jar
log4j-over-slf4j-1.7.13.jar
logging.level.org.springframework=INFO或logging.level.root=INFO就可以解决问题了。 - M. Deinum
