Bug Report There’s a bug report about this on Logback’s JIRA page. There hasn’t been much development since 24/Feb/10 3:57 PM. I’ve just voted to attract attention. You should too. I would provide my own date format that matches ISO 8601’s. Insert “T” This should do the trick: <pattern>%d{“yyyy-MM-dd’T’HH:mm:ss,SSS”} [%thread] %-5level %logger{35} – %msg %n … Read more
In your case LOG_PATH is not defined on startup. You should use ${LOG_PATH:-.} instead , See . But if you define logging.path in your application.properties you will see two log files in . and in ${logging.path} directory. Spring container set LOG_PATH after Logback initialization… Logback is not supported lazy file creation as far as I … Read more
Try this: <configuration> <appender name=”FILE” class=”ch.qos.logback.core.FileAppender”> <file>${user.home}/database.log</file> <append>false</append> <encoder> <pattern>%-5relative %-5level %logger{35} – %msg%n</pattern> </encoder> </appender> <appender name=”STDOUT” class=”ch.qos.logback.core.ConsoleAppender”> <encoder> <pattern>%-5relative %-5level %logger{35} – %msg%n</pattern> </encoder> </appender> <logger name=”jdbc” level=”OFF” /> <logger name=”jdbc.sqlonly” level=”INFO” additivity=”false”> <appender-ref ref=”FILE” /> </logger> <root level=”ERROR”> <appender-ref ref=”STDOUT” /> </root> </configuration>
Disclaimer: I am the founder of log4j, slf4j and logback projects but unaffiliated with log4j 2.0. As I understand it, notwithstanding its name, log4j 2.0 is very different than log4j 1.x. As far as the user API is concerned, log4j 2.0 is largely incompatible with log4j 1.x. Log4j 2.0 provides an adaptation layer for log4j … Read more
You can set a Java system property to output Logback debugging info: java -Dlogback.statusListenerClass=ch.qos.logback.core.status.OnConsoleStatusListener This is further explained by the Logback documentation for automatic status printing (very bottom mentions forcing status output) and the logback.statusListenerClass property: In the absence of status messages, tracking down a rogue logback.xml configuration file can be difficult, especially in production … Read more
I believe the following to be closer to what you want. import ch.qos.logback.classic.Logger; import ch.qos.logback.classic.encoder.PatternLayoutEncoder; import ch.qos.logback.core.FileAppender; import ch.qos.logback.core.util.StatusPrinter; import org.slf4j.LoggerFactory; import ch.qos.logback.classic.LoggerContext; public class Main { public static void main(String[] args) { LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory(); FileAppender fileAppender = new FileAppender(); fileAppender.setContext(loggerContext); fileAppender.setName(“timestamp”); // set the file name fileAppender.setFile(“log/” + System.currentTimeMillis()+”.log”); PatternLayoutEncoder encoder … Read more
Patterns are reusable with variable substitution. <configuration> <property name=”defaultPattern” value=”%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} – %msg%n” /> <appender name=”STDOUT” class=”ch.qos.logback.core.ConsoleAppender”> <encoder> <pattern>${defaultPattern}</pattern> </encoder> </appender> <root level=”debug”> <appender-ref ref=”STDOUT” /> </root> </configuration>
From the Spring blog: Spring Boot users are only affected by this vulnerability if they have switched the default logging system to Log4J2. The log4j-to-slf4j and log4j-api jars that we include in spring-boot-starter-logging cannot be exploited on their own. Only applications using log4j-core and including user input in log messages are vulnerable. Useful explanation points: … Read more

Maven POM setting: <!– https://mvnrepository.com/artifact/org.slf4j/slf4j-api –> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>2.0.6</version> </dependency> See the … Read more
The default strategy assumes that if you don’t have a logback.xml (or one of the other standard file names) in the classpath then you must be happy with the defaults (see LogbackLoggingSystem for details). Spring Boot tries to unify the external configuration switches for common logging sytems, so it looks in logging.config (it didn’t know … Read more
