java如何在MongoDB中插入没有身份验证的数据

1 周，4 日 Questions & Answers 194

使用mongo java驱动程序3.4.2

我使用CMD“mongod”中的这个命令运行Mongodb。我没有使用“mongod--auth”！我不知道为什么它仍然给我例外
就像在CMD中一样，若服务器未在--auth上运行，则不必提供用户名和密码。同样地，我想要实现

我创建了一个将数据插入mongo db的应用程序实际上，它成功地插入了数据，但我仍然遇到异常，并且由于我使用的是swingworker，所以我的应用程序在异常期间冻结了一段时间

MongoDB驱动程序有限制吗？我们不能在没有认证

   public void doJob() {
   server.progressbar.setVisible(true);
   server.progressbar.setIndeterminate(true);

    SwingWorker worker = new SwingWorker() {

        @Override
        protected void done() {
       server.progressbar.setIndeterminate(false);
       server.progressbar.setVisible(false);
        server.total.setText("");       
   CoonectToDB obj=new CoonectToDB();
    obj.callcollections();
    NoAuthCoonectToDB obj2=new NoAuthCoonectToDB();
    obj2.NoAuthconnectDB();

        }

        @Override
        protected void process(List chunks) {
            // Here you can process the result of "doInBackGround()"
            // Set a variable in the dialog or etc.

        }

        @Override
        protected Object doInBackground()  {

         try{ 
        server.newcol.setEnabled(false);
        server.ecoll.setEnabled(false);
        server.ubtn.setEnabled(false);
        String logid="Log-"+logname.getText();

        JList dataList=(loglist);
        int sixe=dataList.getModel().getSize();
        ArrayList arrayList = new ArrayList();
    for (int i = 0; i <sixe; i++) {
    arrayList.add(dataList.getModel().getElementAt(i));
     server.total.setText("Total Log-"+i);

    }
    System.out.println(arrayList);
    Iterator itr = arrayList.iterator();
    String host=hname.getText();
                    String port=spport.getValue().toString();
                    Integer pt = Integer.valueOf(port);                         
                     MongoClient mongoClient = new MongoClient(new ServerAddress(host, pt),            
                                MongoClientOptions.builder()
                                        .serverSelectionTimeout(2000)
                                        .build());

                       DB db = mongoClient.getDB( dbname.getText());
       DBCollection bookCollection = db.getCollection(collectionss.getSelectedValue().toString());
        BasicDBObject doc = new BasicDBObject(logid, arrayList);
        bookCollection.insert(doc);

         Icon icon = new ImageIcon("src\\images\\done.png");
         processimage.setIcon(icon);
        server.consolelog.setText("INFO: Data is inserted succsesfully");

         }catch(Exception e){
          server.consolelog.setText(e.toString());
         }finally{
          server.newcol.setEnabled(true);
          server.ecoll.setEnabled(true);
          server.ubtn.setEnabled(true);
            }

        return null;
        }
    };
    worker.execute();
}

这是个例外

com.mongodb.MongoTimeoutException: Timed out after 2000 ms while waiting for a server that matches ReadPreferenceServerSelector{readPreference=primary}. Client view of cluster state is {type=UNKNOWN, servers=[{address=localhost:27017, type=UNKNOWN, state=CONNECTING, exception={com.mongodb.MongoSecurityException: Exception authenticating MongoCredential{mechanism=null, userName='', source='admin', password=<hidden>, mechanismProperties={}}}, caused by {com.mongodb.MongoCommandException: Command failed with error 18: 'Authentication failed.' on server localhost:27017.
