我在许多论坛上都看到过这个问题,但没有一个能解决我的问题.我正在尝试将示例文档插入MongoDB DB.不幸的是,在插入过程中colReceived.insert(doc)我遇到以下错误：
SEVERE: Servlet.service() for servlet spring threw exception
com.mongodb.MongoTimeoutException: Timed out after 30000 ms while
waiting for a server that matches WritableServerSelector. Client view
of cluster state is {type=UNKNOWN,servers=[{address=localhost:27017,
type=UNKNOWN,state=CONNECTING,
exception={com.mongodb.MongoSocketOpenException: Exception opening
socket},caused by {java.net.ConnectException: Connection refused:
connect}}] at
com.mongodb.connection.BaseCluster.createTimeoutException(BaseCluster.java:369)
这是我的connectToDb方法
MongoClient mongoClient = new MongoClient();
// Now connect to your database
DB db = mongoClient.getDB("test");
System.out.println("connect to database successfully");
DBCollection coll = db.createCollection("mycol",null);
System.out.println("Collection created successfully");
DBCollection colReceived = db.getCollection("mycol");
System.out.println("Collection mycol selected successfully");
BasicDBObject doc = new BasicDBObject("title","MongoDB").append("description","database").append("likes",100)
.append("url","http://www.tutorialspoint.com/mongodb/").append("by","tutorials point");
colReceived.insert(doc);
System.out.println("Document inserted successfully");
