[案例] 使用ByteCodeDL分析log4shell

[Y4er]

环境

引入maven依赖

    <dependencies>
        <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-api</artifactId>
            <version>2.13.3</version>
        </dependency>
        <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-core</artifactId>
            <version>2.13.3</version>
        </dependency>
    </dependencies>

创建Test类

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

public class Test {
    private static final Logger logger = LogManager.getLogger();

    public static void main(String[] args) {
        logger.error(args[0]);
    }
}
