我的记录器没有使用 Spring 创建 RollingFile（使用 logback.xml 配置）

Question

I generate a spring boot project, and I want to log in an external file.

I choose to use Logback implementation, and here is my logback.xml file:

<?xml version="1.0" encoding="UTF-8"?>

<configuration>

    <property name="LOG_PATH" value="./logs" />
    
    <appender name="CONSOLE"
        class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <Pattern>
                %black(%d{ISO8601}) %highlight(%-5level) [%blue(%t)]
                %yellow(%C{1.}): %msg%n%throwable
            </Pattern>
        </layout>
    </appender>

    <appender name="SAVE_TO_FILE"
        class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${LOG_PATH}/spring-boot-logger.log</file>
        <encoder
            class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <Pattern>%d %p %C{1.} [%t] %m%n</Pattern>
        </encoder>
    </appender>

    <!-- LOG everything at INFO level -->
    <root level="INFO">
        <appender-ref ref="SAVE_TO_FILE" />
        <appender-ref ref="CONSOLE" />
    </root>

</configuration>

I use to log with the classic line of code to log:

LoggerFactory.getLogger(CustomLogger.class);

I know that there is an implementation by default, and suspect my logback.xml (which is as the root of the project) is not taking in consideration.

Is there somewhere I have to specify the name of the file, or import it in my application as a resource?

Answer 1

OK,

I had to put the logback.xml in the main path of the project.
