## 也可以换个目录上传
```
/root/Oracle/Middleware/user_projects/domains/base_domain/servers/AdminServer/tmp/.internal/bea_wls_deployment_internal.war
/root/Oracle/Middleware/user_projects/domains/base_domain/servers/AdminServer/tmp/.internal/bea_wls_internal.war 这是上传的路径
/root/Oracle/Middleware/user_projects/domains/base_domain/servers/AdminServer/tmp/_WL_internal/bea_wls_internal
/root/Oracle/Middleware/user_projects/domains/base_domain/servers/AdminServer/tmp/_WL_internal/bea_wls_deployment_internal
bea_wls_internal 
bea_wls_deployment_internal 在同目录
这是漏洞war位置
