java - 如何禁用 Javalin 日志记录

Question

我想在 Javalin 下关闭此日志记录:

[main] INFO org.eclipse.jetty.util.log - Logging initialized @850ms to org.eclipse.jetty.util.log.Slf4jLog
[main] INFO io.javalin.Javalin - Starting Javalin ...
[main] INFO io.javalin.Javalin - Listening on http://localhost:8003/
[main] INFO io.javalin.Javalin - Javalin started in 334ms \o/
OpenJDK 64-Bit Server VM warning: Sharing is only supported for boot loader classes because bootstrap classpath has been appended
[main] INFO io.javalin.Javalin - Starting Javalin ...
[main] INFO io.javalin.Javalin - Listening on http://localhost:6667/
[main] INFO io.javalin.Javalin - Javalin started in 7ms \o/
[main] INFO io.javalin.Javalin - Stopping Javalin ...
[main] INFO io.javalin.Javalin - Javalin has stopped
[main] INFO io.javalin.Javalin - Stopping Javalin ...
[main] INFO io.javalin.Javalin - Javalin has stopped

...但是Javalin似乎没有办法关闭这些日志。有办法吗？谢谢

Javalin 使用 SLF4J用于日志记录(您甚至可以在第一条消息中看到类名Slf4jLog)。这是一个抽象，可以与许多不同的实际实现一起使用，因此第一步是找到您的项目使用哪个。列出依赖项( Gradle 、 Maven )并查找 slf4j-<something> (slf4j-api 除外)或 logback-classic 。然后看https://www.slf4j.org/manual.html#swapping对于您找到的并找到如何将其配置为设置为高于 INFO 的级别.

例如如果您关注了

Javalin does not have a logger included, which means that you have to add your own logger. If you don’t know/care a lot about Java loggers, the easiest way to fix this is to add the following dependency to your project:

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-simple</artifactId>
    <version>1.7.26</version>
</dependency>
