连接到Mongo DB时发生异常：
以下是堆栈跟踪：
Exception in thread "main" com.mongodb.CommandFailureException: { "serverUsed" : "127.0.0.1:27017" , "ok" : 0.0 , "code" : 18 , "errmsg" : "Authentication failed."}

以下是代码段：
private static void getConnectionMongo(){
try{
String uri = "mongodb://accountUser:password@127.0.0.1/test";
MongoClientURI mongoClientURI = new MongoClientURI(uri);
MongoURI mongoURI = new MongoURI(mongoClientURI);
Mongo mongo = new Mongo(mongoURI);
UserCredentials userCredentials = new UserCredentials("accountUser", "password");
SimpleMongoDbFactory dbFactory = new SimpleMongoDbFactory(mongo, "test", userCredentials);
MongoTemplate mongoTemplate = new MongoTemplate(dbFactory);
DBCollection collection = mongoTemplate.getCollection("table");
DBCursor cursor = collection.find();
while(cursor.hasNext()){
System.out.println(cursor.next());
}
}
catch(UnknownHostException e){
}
}
以下是mongo Shell的代码段：
db.auth('accountUser','password');1个
这些是使用的jar文件：
spring-data-mongodb-1.3.0.RELEASE，
mongo-java-driver-2.13.2
任何建议都是可取的。谢谢 ！！
最佳答案
要么通过这个URI
String uri = "mongodb://accountUser:password@127.0.0.1/test";
或将userCredentials传递给构造函数都不能一起使用，仍然可以突出显示哪一行会引发错误
MongoTemplate mongoTemplate = new MongoTemplate(dbFactory);DBCollection collection = mongoTemplate.getCollection("table");DBCursor cursor = collection.find();
