死亡历险，DELPHI以TByteDynArray（Bytes）方式传递图片到JAVA的WEBSERVICE保存

DELPHI以TByteDynArray（Bytes）方式传递图片到JAVA的WEBSERVICE保存

procedure TForm1.btn17Click(Sender: TObject);

var

  strm : TMemoryStream;

  AFileData: TByteDynArray;

  fsize:Integer;

begin

    strm := TMemoryStream.Create;

    img1.Picture.Graphic.SaveToStream(strm);//把图片转化成内存流

    strm.Position:=0;//切记，操作图片前一定要这句，否则错误

    //把内存流转化成TByteDynArray

    fsize:=strm.Size;

    SetLength(AFileData,fsize);

    strm.Read(AFileData[0],fsize);

    addResult:=ServiceHello1.addUser_Byte(edt4.Text, AFileData);

  if (addResult='ok') then

  begin

    ShowMessage('添加成功');

  end;

end;

这是JAVA的WEBSERVICE接口

function  addUser_Byte(const arg0: WideString; const arg1: TByteDynArray): WideString; stdcall;

这是JAVA的WEBSERVICE函数

ServiceHello.java
public String addUser_Byte(String sname, byte[] bytes) {
String result = "";
try {
   login getUserList00=new login();
   result = getUserList00.addUser_Byte(conn, sname, bytes);
} catch (Exception e) {

            e.printStackTrace();
}
return result;
}

login.java
public String addUser_Byte(Connection conn, String sname, byte[] bytes) throws SQLException, IOException {

        String sql = "";

        String result = ""; 

        

        byte[] blob1 = null; 

        blob1 = bytes;

        result = new sun.misc.BASE64Encoder().encode(blob1);

        System.out.println(result);

               

        sql = "select * from D_J_TABLE1 where name='"+sname+"' ";//定义SQL语句

        pstmt = conn.prepareStatement(sql); //根据sql创建PreparedStatement

        rs = pstmt.executeQuery(); //执行查询，返回结果集

        if (rs.next()) {

        result = "repeat";

        }

        else

        {        
       Date time = new Date(System.currentTimeMillis());
       SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
       String current = sdf.format(time);
       
       if("".equals(sname) || sname == null)
       {
       
result = "empty";
       }
       else
       {
       
sql = "insert into D_J_TABLE1(name,addtime,image1)values('"+sname+"',sysdate,?) ";
       
           pstmt = conn.prepareStatement(sql); //根据sql创建PreparedStatement
           pstmt.setBytes(1, blob1);
           rs = pstmt.executeQuery(); //执行查询，返回结果集
           if (rs.next()) {
           
result = "ok";
           }
       }

        }

        return result;

    }
