log4j2 と logback の設定ファイルメモ

Java

今更、サンプルとしてメモしておきたかったので。。。
log4j2
Maven pom.xml の記述

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-core</artifactId>
    <version>2.20.0</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-api</artifactId>
    <version>2.20.0</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-jcl</artifactId>
    <version>2.20.0</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-1.2-api</artifactId>
    <version>2.20.0</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-slf4j-impl</artifactId>
    <version>2.20.0</version>
</dependency>
<dependency>
   <groupId>org.slf4j</groupId>
   <artifactId>slf4j-api</artifactId>
   <version>1.7.36</version>
</dependency>

Log4j 1.2 → Log4j2 の為に、log4j-1.2-api を使う。
Commons Logging → Log4j2 の為に、log4j-jcl を使う。
SLF4J → Log4j2 の為に、log4j-slf4j-impl

（参考）https://howtodoinjava.com/log4j2/maven-gradle-config/

slf4j-api を使うなら、1.7.36 でないと
以下のメッセージが出てしまう。

SLF4J: No SLF4J providers were found.
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See https://www.slf4j.org/codes.html#noProviders for further details.
SLF4J: Class path contains SLF4J bindings targeting slf4j-api versions 1.7.x or earlier.
SLF4J: Ignoring binding found at [jar:file:/C:/Users/xxxxx/.m2/repository/org/apache/logging/log4j/log4j-slf4j-impl/2.20.0/log4j-slf4j-impl-2.20.0.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See https://www.slf4j.org/codes.html#ignoredBindings for an explanation.

logback

<root level="OFF">

<logger name="org.abc" level="info" />
<logger name="org.labo">

</configuration>

root の level を OFF にすることで下記 logger でレベルを override
