Android版/ MongoDB的：＆QUOT; NoClassDefFoundError的：com.mongodb.DBPortPool＆QUOT; [英] Android/MongoDB: "NoClassDefFoundError: com.mongodb.DBPortPool"

问题描述

我想连接到我的MongoDB（托管在 MongoHQ ）。我碰到下面的错误，当我想连接到数据库中（与Java驱动程序）

I'd like to connect to my MongoDB (hosted on MongoHQ). I get the following error when I want connect to the database (with the Java driver)

ERROR/AndroidRuntime(597): java.lang.NoClassDefFoundError: com.mongodb.DBPortPool
ERROR/AndroidRuntime(597):     at com.mongodb.DBPortPool$Holder.get(DBPortPool.java:52)
ERROR/AndroidRuntime(597):     at com.mongodb.DBTCPConnector._set(DBTCPConnector.java:380)

ERROR/AndroidRuntime(597):     at com.mongodb.Mongo.<init>(Mongo.java:114)
ERROR/AndroidRuntime(597):     at xxx.MainActivity$1.onClick(MainActivity.java:29)

我用下面的code：

I use the following code:

Mongo mng = new Mongo("flame.mongohq.com", 27073); // <- error
DB mngDb = mng.getDB("xxx");
mngDb.authenticate("xxx", "xxx".toCharArray());
DBCollection mngColl = mngDb.getCollection("xxx");
// mText.setText("Data Count: "+Long.toString(mngColl.getCount()));

我通过属性> Java构建路径>库>添加Externel JAR

I added the driver in Eclipse via Properties>Java Build Path>Libraries>Add Externel JAR

推荐答案

该DBPortPool对JMX一个依赖关系JMX但不支持在Android上。

The DBPortPool has a dependancy on JMX however JMX is not supported on android.

出于兴趣，你有什么用呢？正如你会希望避免从手机传递数据库的用户名/密码没有安全基础设施。

Out of interest, what is your use case? As you will want to avoid passing database username/pwd from your phone without security infrastructure.
