在pom.xml加入依赖

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>$slf4j.version</version>
</dependency>

Demo.java

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

public class Demo
    private static final Logger logger = LoggerFactory.getLogger(Demo.class);
    
    public void loggerDemo(Integer code) 
        try 
            logger.info("accept:=========命令为：", code);
         catch (Exception var2) 
            logger.error("error:============0x:" + code);
            var2.printStackTrace();
