#1 Created at ... [Delete] [Delete and Lock User]

代码：Main.java

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

public class Main {
    public static void main(String[] args) {
        Log log = LogFactory.getLog(Main.class);
        log.info("test");
        log.error("error");
    }
}

文件信息：

.
├── commons-logging-1.2.jar
├── log4j2.xml
├── log4j-api-2.13.3.jar
├── log4j-core-2.13.3.jar
├── log4j-jcl-2.13.3.jar
└── Main.java

编译运行：

javac -cp commons-logging-1.2.jar Main.java

# 需要指定当前路径及依赖包路径
java -cp .:commons-logging-1.2.jar:log4j-api-2.13.3.jar:log4j-core-2.13.3.jar:log4j-jcl-2.13.3.jar Main

最终会在当前目录自动创建 log 目录及日志文件。
