java连接mongodb报错

[hkh_1012]

环境mongodb3.0.1,虚拟机centos7
使用shell可以用mongo连接mongod

Mongo mg = new Mongo("192.168.59.128",27017);
		DB db = mg.getDB("mydb");
		for(String s:db.getCollectionNames()){
			System.out.println(s);
		}

异常如下：

也可以用127.0.0.1试试

意思是连接超时，那就更改连接最大时间

我也遇到了这个问题，最终解决的办法是： 我在用命令mongo localhost:9927 连接db后，发现显示为application:SECONDARY> show collections; 本以为是主节点的，居然成了副节点了，原来是因为我把三个节点同时启动的原因，所以没有保证9927是第一个启动的。 关掉再重新打开9928的节点后，9927就成了主节点了，连接到9927显示为application:SECONDARY> show collections。 这个时候再测试 已经ok了。 [success] Total time: 8 s, completed 2015-10-30 14:54:45
