[Java知识库]JAVA调用IBM的Lotus Notes

JAVA调用IBM的Lotus Notes

目前IBM的Lotus Notes是已经比较小众，很少人在用了，刚好公司系统要调用Lotus Notes的数据，所以就记录下，接下来我们直接上代码。

1、引入对应的依赖
因为但是没有找到对应的依赖，所以我直接下载了Jar包
Notes.jar和NCSO.jar

 <!--Notes-->
        <dependency>
            <groupId>com.Notes</groupId>
            <artifactId>Notes</artifactId>
            <version>0.0.1-SNAPSHOT</version>
            <scope>system</scope>
            <systemPath>${project.basedir}/src/main/resources/lib/Notes.jar</systemPath>
        </dependency>
        <dependency>
            <groupId>com.Ncso</groupId>
            <artifactId>Ncso</artifactId>
            <version>0.0.1-SNAPSHOT</version>
            <scope>system</scope>
            <systemPath>${project.basedir}/src/main/resources/lib/NCSO.jar</systemPath>
        </dependency>

2、创建notes.proterties配置文件，保存Notes 系统的路径

#例如
TEST_URL=apps\\test.nsf
#你的Notes服务器登陆密码
KEY_NOTES_PWD=TEST
#你的Notes服务器地址
EMAIL_SERVER_URL=TEST

3、创建PropertieUtil.Class工具类，读取notes.proterties中Notes系统的路径，并且取得Notes连接

import lombok.extern.slf4j.Slf4j;
import lotus.domino.Database;
import lotus.domino.NotesException;
import lotus.domino.NotesFactory;
import lotus.domino.Session;

import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;

/**
 * @Value注解获取配置而文件的数据
 * @author jackson
 *
 */
@Slf4j
public class PropertieUtil {

	public static String KEY_NOTES_PWD = "KEY_NOTES_PWD";
	public static String KEY_SERVER_URL = "KEY_SERVER_URL";
	//TEST_URL
	public static String TEST_URL = "TEST_URL";



	static Properties proties = null;
	static{
		proties = new Properties();
		InputStream is = PropertieUtil.class.getClassLoader().getResourceAsStream("notes.properties");
		try {
			proties.load(is);
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
	
	/**根据properties的key获取数据库
	 * @throws NotesException */
	public static Database getDbConnection(String proKey) throws NotesException {
		return new PropertieUtil().getSession().getDatabase(proties.getProperty(KEY_SERVER_URL),proties.getProperty(proKey));
	}
	
	/**根据url获取数据库
	 * 
	 * @param notesUrl
	 * 		String notes数据库Url
	 * @return
	 * @throws NotesException
	 */
	public static Database getDbByNotesUrl(String notesUrl) throws NotesException {
		return  new PropertieUtil().getSession().getDatabase(proties.getProperty(KEY_SERVER_URL),proties.getProperty(notesUrl));
	}


	/**创建session
	 * @throws NotesException
	 * @throws IOException */
	public Session getSession() throws NotesException {
		return  NotesFactory.createSession((String)null,(String)null, (String) proties.get(KEY_NOTES_PWD));
	}
	
	/**
	 * 根据配置文件key获取value
	 * @param keyStr
	 * 			String key
	 * @return
	 */
	public static String getPropertyByKey(String keyStr) {
		return proties.getProperty(keyStr);
	}
	
	
	/**根据properties的key获取数据库
	 * @throws NotesException */
	public static Database getEmailDbConnection(String proKey) throws NotesException {
		return  new PropertieUtil().getSession().getDatabase(proties.getProperty(EMAIL_SERVER_URL),proties.getProperty(proKey));
	}
	
}

3、与Notes系统交互

①获取Notes系统View数据关键代码示例

public Map<String, String> getData(String param) throws Exception {
        Map<String, String> map = new HashMap<>(16);
        NotesThread.sinitThread();
        Database db = PropertieUtil.getDbConnection(PropertieUtil.TEST_URL);
        if (!db.isOpen()) {
            throw new Exception("Can not find database in Notes");
        }
        //Notes中所查询的View
        View view = db.getView("test\\test");
        //参数条件
        Vector<String> vector = new Vector<>();
        vector.addElement(param);
        //根据参数条件获取数据
        Document document = view.getDocumentByKey(vector);
        //根据Notes系统中的Filed Name的类型获取数据
        //Vector plantList = document.getItemValue("fPlantByCtmPN");
        String staffNo = document.getItemValueString("fStaffNo");
        map.put("staffNo ", staffNo );
        return map;
    }

②获取Notes系统中的附件关键代码示例

//附件所在的Notes URL
Database attDb = PropertieUtil.getDbConnection(PropertieUtil.ATTACHMENT_URL);
                View attView = attDb.getView("Attachment\\SortByKey");
                Vector<String> vector = new Vector<>();
                vector.addElement("frmSO");
                vector.addElement(attDocSeqNo);
                Document attDoc = attView.getDocumentByKey(vector, true);
                if (null == attDoc) {
                    throw new Exception("Can not find this record in Attachment Notes!");
                }
                RichTextItem richTextItem = getRichTextItem(attDoc, "AF_ParAttachment");
                List<String> newAttachList = getRichItemPath(richTextItem, attachPath);


/**
     * 获取RichTextItem
     *
     * @param docCur    Document notes文档
     * @param fieldName String 附件字段名
     * @return RichTextItem
     * @throws NotesException
     */
    public RichTextItem getRichTextItem(Document docCur, String fieldName) throws NotesException {
        RichTextItem richItem = (RichTextItem) docCur.getFirstItem(fieldName);
        if (richItem == null) {
            richItem = docCur.createRichTextItem(fieldName);
        }
        return richItem;
    }

    /**
     * 获取 所有 附件path
     *
     * @param richItem RichTextItem 附件对象（多附件）
     * @return List<String>
     * @throws NotesException
     */
    public List<String> getRichItemPath(RichTextItem richItem, String path) throws NotesException {
        List<String> attachNameList = new ArrayList<String>();
        if (richItem != null) {
            Enumeration<?> elements = richItem.getEmbeddedObjects().elements();
            while (elements.hasMoreElements()) {
                EmbeddedObject eo = (EmbeddedObject) elements.nextElement();
                if (eo.getType() == EmbeddedObject.EMBED_ATTACHMENT) {
                    //以EMAil开头的无需显示
                    if (eo.getSource().toUpperCase().startsWith("EMAIL")){
                        continue;
                    }
                    String filePath = MyWebUtils.getPathBySys(path) + File.separator + eo.getSource();
                    //下载文件到本地
                    eo.extractFile(filePath);
                    attachNameList.add(eo.getSource());
                }
            }
        }
        return attachNameList;
    }

③调用Notest发送邮件关键代码示例

/**
	 * 发送邮件
	 * @param dbCur 
	 * 		Database notes数据库
	 * @param docCur
	 * 		Document notes Document
	 * @param sendBy
	 * 		String 发件人
	 * @param sendto
	 * 		Vector<String> 收件人
	 * @param copyTo
	 * 		Vector<String> 抄送
	 * @param comment
	 * 		String 备注内容,显示在第一行
	 * @param emailSubject
	 * 		String 邮件主题
	 * @param form
	 * 		String Document 表单名
	 * @param body
	 * 		String 主体内容
	 * @return
	 * @throws NotesException
	 */
	public boolean sendMail(Database dbCur,Document docCur,String sendBy,Vector<String> sendto,Vector<String> copyTo,String comment,String emailSubject,String form,String body) throws NotesException {
		// 设置邮件参数
		NotesMail mail = new NotesMail();
		mail.setSendBy(sendBy);//发件人
		mail.setSubject(emailSubject);//邮件主题
		mail.setBody(body);//主题内容
		mail.setSendto(sendto);//收件人
		mail.setCopyto(copyTo);//抄送人
		mail.setForm(form);//文档表单
		mail.setDoc(docCur);//文档对象
		/** 备注内容,显示在第一行*/
		mail.setComment(comment);
		mail.setDocLink(true);//是否带富文本link
		// 发送邮件
		mailWithAttah(mail, dbCur);
		return true;
	}

/**
	 * 发送邮件,附带富文本内容
	 * @param mail 邮件对象
	 * @param db Notes数据库
	 * @return
	 */
	public boolean mailWithAttah(NotesMail mail, Database db){
		try {
			View viParam = db.getView("cfgParameter");
			viParam.refresh();
			Document docParameter = viParam.getFirstDocument();
			RichTextItem itmBodyEnd = null;
			if (docParameter != null) {
				itmBodyEnd = (RichTextItem) docParameter.getFirstItem("AF_MailAppendages");
			}
			docMail = db.createDocument();
			docMail.replaceItemValue("Form", mail.getForm());
			if (mail.getIcon()!=0) {docMail.replaceItemValue("_ViewIcon", mail.getIcon());}
			docMail.replaceItemValue("Sendto", mail.getSendto());
			docMail.replaceItemValue("Copyto", mail.getCopyto());
			docMail.replaceItemValue("BlindCopyTo", mail.getBlindCopyto());
			docMail.replaceItemValue("Subject", mail.getSubject());
			rtItem = docMail.createRichTextItem("Body");
			if (mail.getComment()!=""){
				rtItem.appendText(mail.getComment());
				rtItem.addNewLine(1);
			} 
			if (mail.getBody()!=""){
				rtItem.appendText(mail.getBody());
				rtItem.addNewLine(1);
			}
			if (mail.isDocLink()){
				if (mail.getDoc()!=null){
					rtItem.addNewLine(2);
					rtItem.appendText("Please click the link to open the document ==> ");
					rtItem.appendDocLink(mail.getDoc(), "");
				}
			}
			if (itmBodyEnd != null){
				rtItem.addNewLine(1);
				rtItem.appendRTItem(itmBodyEnd);
			}
			docMail.send(false);
		} catch (NotesException e) {
			e.printStackTrace();
			return false;
		}
		return true;
	}
