As stated in tutorialspoint : SLF4J stands for Simple Logging Facade for Java. It provides a simple abstraction of all the logging frameworks. It enables a user to work with any of the logging frameworks such as Log4j, Logback, JUL (java.util.logging), etc. using single dependency. This means that you have to provide a concrete java … Read more
I don’t think that you can overwrite logback.xml-definitions from an included file. But I have an approach that solves your question regarding overriding the root-logger-level, using variable substitution with default values: logback.xml <configuration> <include file=”includedFile.xml” /> <!– STDOUT appender stuff –> <root level=”${root.level:-DEBUG}”> <appender-ref ref=”STDOUT” /> </root> <configuration> includedFile.xml <included> <!– override the default value; … Read more
I had the exact same problem and could only see the dependency coming from spring boot. It also brought in log4j-over-slf4j, which clashed with my own requirement of slf4j-log4j12. Solved by adding the exclusions below. This is more specific that excluding the spring boot logging. <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> <exclusions> <exclusion> <artifactId>logback-classic</artifactId> <groupId>ch.qos.logback</groupId> </exclusion> <exclusion> <artifactId>log4j-over-slf4j</artifactId> … Read more
it should be fairly easy. you’ll need to implement your own Logger and LoggerFactory. you will not have to change existing code at all. after doing that you’ll need to implement StaticLoggerBinder to return your logger factory and class name. if you download the slf4j zip file then you get the source for all the … Read more
You can use sysout-over-slf4j. The sysout-over-slf4j module allows a user to redirect all calls to System.out and System.err to an SLF4J defined logger with the name of the fully qualified class in which the System.out.println (or similar) call was made, at configurable levels. If you are not using Maven, download the jar and add it … Read more
You also have to install Lombok into Eclipse. See also this answer on how to do that or check if Lombok is installed correctly. Full Disclosure: I am one of the Project Lombok developers.
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
From the SLF4J FAQ: SLF4J is conceptually very similar to JCL. As such, it can be thought of as yet another logging facade. However, SLF4J is much simpler in design and arguably more robust. In a nutshell, SLF4J avoid the class loader issues that plague JCL. Do a google for “JCL classloader issues” for more … 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
Simply add \n at the end of the string to log. LOGGER.info(“Person’s name is {} .\n”, person.getName()); If you are in a windows environment use \r\n To get the right value of new line if you don’t know the end operating system of your application you can use the property line.separator String lineSeparator = System.getProperty(“line.separator”); … Read more
