连接到 Mongo 时出现身份验证错误

Question

连接到 Mongo DB 时出现异常：

下面是堆栈跟踪：

Exception in thread "main" com.mongodb.CommandFailureException: { "serverUsed" : "127.0.0.1:27017" , "ok" : 0.0 , "code" : 18 , "errmsg" : "Authentication failed."}

    at mongoOperations.mongoOperations.getConnectionMongo(mongoOperations.java:103)
    at mongoOperations.mongoOperations.main(mongoOperations.java:138)

以下是代码片段：

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){

    }
}

以下是来自 mongo Shell 的代码 sn-p：

db.auth('accountUser','password'); 1

这些是使用的 jar 文件： spring-data-mongodb-1.3.0.RELEASE, mongo-java-driver-2.13.2

任何建议都会很有价值。谢谢！！

Answer 1

要么传递这个 URI

String uri = "mongodb://accountUser:password@127.0.0.1/test";

或者将 userCredentials 传递给构造函数两者不能一起使用，你仍然可以突出显示它到底是哪一行引发了错误

1. MongoTemplate mongoTemplate = new MongoTemplate(dbFactory);
2. DBCollection collection = mongoTemplate.getCollection("table");
3. DBCursor cursor = collection.find();
