我正在开发一个 Spring Boot Web 应用程序，我在其中将一个长时间运行的进程添加到 ScheduledExecutorService。
为了确保它按照我认为的方式运行，我正在使用 System.out.println() 来调试长时间运行的进程。
我的问题是我一直收到这些
NioEndpoint FINER | timeout completed: keys processed=1; now=1492721057929; nextExpiration=1492721057927; keyCount=0; hasEvents=false; eval=false {timeout() / 18} 04:44.714 NioEndpoint FINER | timeout completed: keys processed=0; now=1492721058713; nextExpiration=1492721058712; keyCount=0; hasEvents=false; eval=false {timeout() / 17} 04:44.931 NioEndpoint FINER | timeout completed: keys processed=1; now=1492721058931; nextExpiration=1492721058929; keyCount=0; hasEvents=false; eval=false {timeout() / 18} 04:44.718 NioEndpoint FINER | timeout completed
在输出窗口中出现垃圾信息，这使得无法破译其他日志记录。
我尝试将 logging.level.root=ERROR 添加到 application.properties，但并没有删除它们。
如何让它们不出现，它们表示什么？

最佳答案
您没有在您的应用程序中提供有关日志记录配置的详细信息，因此很难确定实际问题。在 application.properties 中设置以下属性应该阻止 NioEndpoint 日志消息。
logging.level.org.apache.tomcat=INFO
logging.level.org.apache.tomcat.util.net=WARN
您可以在 tomcat github 找到有关 NioEndpoint.java 的详细信息.该类中有一个 timeout 方法记录此消息。
编辑
您发布的日志消息包含 FINER 日志消息，这意味着您正在使用 java.util.logging。如果您已为 java.util.logging 配置了 spring-boot，则在 logging.properties 文件中添加以下属性。请检查您的应用程序是否正在使用 jdk/jre 提供的 logging.properties 文件或自定义 logging.properties 文件并修改适当的文件。
org.apache.tomcat.level=INFO
org.apache.tomcat.util.net.level=WARNING
如果您不想通过包级日志记录配置(这是首选)来控制它，那么您可以在 logging.properties 文件中将全局日志记录级别和 ConsoleHandler/FileHandler 日志级别设置为 INFO。
.level=INFO
java.util.logging.ConsoleHandler.level=INFO
请注意 java.util.logging 的日志级别略有不同。您不能在此处设置 ERROR，但可以设置最高级别的 SEVERE。详情请查看https://docs.oracle.com/javase/7/docs/api/java/util/logging/Level.html
