建立用户到用户建表的步骤： 
Server 
建立：create user jtb_std identified by "jtb_std"; 
授权：grant create session to jtb_std; 
            grant create table to  jtb_std; 
            grant create tablespace to  jtb_std; 
            grant create view to  jtb_std; 

grant unlimited tablespace to jtb_std;

			 System.out.println(password);	
			 System.out.println("根据用户名取得的密码");
		     SysUserInfo    list  = sysUserInfoService.getUserbyLoginName(username);
			 System.out.print(list.getLoginPassword());
