java中通过jacob调用dts进行数据导入导出
在一个项目中需要金蝶软件对接,但是业务服务器和财务服务器相隔很远(中间经过好几台服务器,有内网也有外网),从一个内网向另一个内网中传输时,需要外网辅助,因为不让原始数据受污染,使用了DTS数据同步到另一台服务器,然后再上传至外网。
sqlserver下 调用dts
EXEC master.dbo.xp_cmdshell 'dtsrun /S /E /N"MyPack" /A"begintime":8=2013-06-01 /A"endtime":8=2013-08-20'
create table dtsSync( beginDate datetime, endDate datetime, execDate datetime primary key ) insert into dtsSync values('2013-08-01', '2013-08-23', getdate()); declare @beginDate varchar(10), @endDate varchar(10), @command varchar(255) select @beginDate=convert(varchar(10), max(endDate) + 1,120) from dtsSync set @endDate=convert(varchar(10),getdate(),120) set @command='dtsrun /S /E /N"MyPack" /A"begintime":8=' + @beginDate + ' /A"endtime":8=' + @endDate print @command EXEC master.dbo.xp_cmdshell @command select @endDate=convert(varchar(10),max(dt_signDate),120) from rpt_xiaoshou insert into dtsSync values(@beginDate, @endDate, getdate())
第一步:
下载jacob
http://danadler.com/jacob/jacobBin_17.zip
解压后将dll文件放到%JAVA_HOME%\jre\bin
和 %JAVA_HOME%\bin(如果不放:java.lang.UnsatisfiedLinkError: no jacob in java.library.path)
目录下,将jar文件放到%JAVA_HOME%\jre\lib\ext目录下(各种报错,还是放到工程中吧),不用再配置环境变量
第二步:
创建dts文件
直接用sqlserver2000的导入导出工具创建一个dts任务,并保存为存储结构文件,放到比如d:\temp\dts\dts_test.dts
第三步:
通过java调用dts文件执行数据导入导出
package dbf; import java.text.SimpleDateFormat; import java.util.Date; import com.jacob.activeX.*; import com.jacob.com.*; public class ExportDts { public void exportdbf() { SimpleDateFormat localTime = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); String importFileName = "D:/temp/dbf"; //这里导出的DBF要存放的路径 String DtsPath = "D:/temp/dts/dts_test.dts"; //这里是DTS文件的路径 try { System.out.println("start:" + localTime.format(new Date())); ActiveXComponent app = new ActiveXComponent("DTS.Package2"); Dispatch.callN(app, "LoadFromStorageFile",new Variant[] {new Variant(DtsPath),new Variant("")}); //重新设置路径 Dispatch DTSconns = Dispatch.get(app,"Connections").toDispatch(); Dispatch DTSconn = Dispatch.callN(DTSconns,"Item",new Variant[]{new Variant(2)}).toDispatch(); Dispatch.put(DTSconn,"DataSource",new String(importFileName)); //执行 Dispatch.callN(app, "Execute", new Variant[] {}); //得到执行的结果 Dispatch DTSsteps = Dispatch.get(app,"Steps").toDispatch(); Dispatch DTSstep = Dispatch.callN(DTSsteps,"Item",new Variant[]{new Variant(1)}).toDispatch(); Variant ResultValue = Dispatch.get(DTSstep,"ExecutionResult"); if(ResultValue.toInt()==0){ System.out.println("导出成功"); }else{ System.out.println("导出失败"); } System.out.println("end:" + localTime.format(new Date())); } catch (Exception ex) { ex.printStackTrace(); } } }
