How to configure and initialize the Scala Logging SLF4J box in the Java class library

Configuring and initializing the Scala Logging SLF4J framework in the Java class library Introduction: Scala Logging is a simple logging framework for the Scala language, based on the SLF4J (Simple Logging Facade for Java) framework. It provides a concise API for logging and supports different logging implementations such as Logback and Log4j. This article will introduce how to configure and initialize the Scala Logging SLF4J framework in the Java class library. Step: 1. Add Dependency: Add dependencies for Scala Logging and SLF4J in the project's build configuration file (such as pom.xml or build. gradle). The following are examples of dependency configurations for Maven and Gradle: Maven: <dependencies> <dependency> <groupId>com.typesafe.scala-logging</groupId> <artifactId>scala-logging_2.13</artifactId> <version>3.9.4</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.32</version> </dependency> <-- Add dependencies for the log implementation you have chosen, such as Logback or log4j --> </dependencies> Gradle: groovy dependencies { implementation 'com.typesafe.scala-logging:scala-logging_2.13:3.9.4' implementation 'org.slf4j:slf4j-api:1.7.32' //Add dependencies for the log implementation you have chosen, such as Logback or log4j } 2. Configuration log implementation: Add corresponding dependencies based on the log implementation you have chosen. For example, if you choose Logback, you can add the following dependencies: Maven: <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.2.5</version> </dependency> Gradle: groovy implementation 'ch.qos.logback:logback-classic:1.2.5' 3. Initialize Scala Logging: At the entrance of the application, call the 'LoggerFactory. getLogger' method to initialize Scala Logging. Here is an example: import org.slf4j.LoggerFactory; import com.typesafe.scalalogging.Logger; public class MyApp { private static final Logger logger = Logger(LoggerFactory.getLogger(MyApp.class)); public static void main(String[] args) { logger.info("Hello, Scala Logging!"); //Other Log Operations } } In the above example, we obtain the SLF4J Logger object through the 'LoggerFactory. getLogger' method and wrap it as a Scala Logging Logger object using the constructor of the 'Logger' class. Then, we can use the concise API provided by Scala Logging to record logs. 4. Record Log: Now, you can use the API provided by Scala Logging to record your logs. Here are some examples: logger.debug("This is a debug message"); logger.info("This is an info message"); logger.warn("This is a warning message"); logger.error("This is an error message", throwable); In the above example, 'logger' is the Scala Logging Logger object that we initialized. We can use the 'debug', 'info', 'warn', and 'error' methods to record different levels of log messages. If there are exceptions that need to be recorded, you can pass' throw 'as a parameter to the' error 'method. Summary: By adding dependencies for Scala Logging and SLF4J, and adding corresponding dependencies based on the selected log implementation, we can configure and initialize the Scala Logging SLF4J framework in the Java class library. Then, we can use the API provided by Scala Logging to record logs, and set the log level and other configurations as needed. This way, we can easily use Scala Logging for logging in our Java class library.
