slf4j如何进行logback配置呢?

步骤一:pom.xml添加logback依赖

<dependency>
	<groupId>org.slf4j</groupId>
	<artifactId>slf4j-api</artifactId>
	<version>1.7.25</version>
</dependency>
<dependency>
	<groupId>ch.qos.logback</groupId>
	<artifactId>logback-classic</artifactId>
	<version>1.2.3</version>
</dependency>
<dependency>
	<groupId>ch.qos.logback</groupId>
	<artifactId>logback-core</artifactId>
	<version>1.2.3</version>
</dependency>

步骤二:配置logback

编写测试代码

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class LoggerTest {
    private static final Logger logger = LoggerFactory.getLogger(LoggerTest.class);

    public static void main(String[] args) {
	logger.error("严重警告");
	logger.warn("警告");
	logger.info("普通信息");
	logger.debug("调试信息");
    }
}
