由于项目的需要,要对Domino服务器上的文档以及其附件做索引,提供搜索.所以自己也先整理一下思路.程序中使用DIIOP协议连接服务器(需要NCSO.jar),遍历视图中的文档,再读取其附件,以及需要建索引的字段,然后建索引,由于一个文档可能包含多个附件,所以要将各附件解析后h合并再建索引.

本文先完成对Domino文档以及其附件的读取.步骤比较简单

1.获得Sessio,需要用户,密码以及IOR.
Session session = NotesFactory.createSessionWithIOR(IOR, user, pass);

2.选择数据库和视图
Database db = session.getDatabase(null, “datastorge01.nsf”);
View view = db.getView(“(SWSearch_main)”);

3.遍历文档,读取字段信息以及拆解附件.
view.getFirstDocument();
view.getNextDocument(doc);
Vector attNames = session.evaluate(“@AttachmentNames”,doc);//附件

JAVA代码:

package notesdemo;

import java.io.File;
import java.util.Vector;
import lotus.domino.Database;
import lotus.domino.Document;
import lotus.domino.EmbeddedObject;
import lotus.domino.NotesException;

import lotus.domino.Session;
import lotus.domino.View;

public class Main {
	public Integer attCount = 0;
	public Long attSize = new Long(0);
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) throws NotesException {
        // TODO code application logic here
		String basePath ="/root/Desktop/notesfiles/";
		Main demo = new Main();
		Long t = System.currentTimeMillis();
		System.out.println("开始:");

		demo.Connection();
		System.out.println("耗时: " + (System.currentTimeMillis()- t)/1000 + "秒   附件数量:" + demo.attCount + "  附件总大小:" + demo.attSize/1024/1024 + "MB");
    }
	public void Connection() throws NotesException{

		String basePath ="/root/Desktop/notesfiles/";

		}
	}
}

总得来说,DIIOP的接口还是比较简单的.
