Question

1 - 在mongo shell中创建用户

> use admin
switched to db admin
> db.createUser( { user:"tiger", pwd:"secret", roles: [ { role:"readWrite", db:"zoo" } ] } )
Successfully added user: {
    "user" : "tiger",
    "roles" : [
        {
            "role" : "readWrite",
            "db" : "zoo"
        }
    ]
}

2 - 从Java连接到数据库

List<ServerAddress> seeds = new ArrayList<ServerAddress>();
seeds.add( new ServerAddress( "remoteserver" ));
List<MongoCredential> credentials = new ArrayList<MongoCredential>();  
credentials.add(
    MongoCredential.createMongoCRCredential(
        "tiger",
        "admin",
        "secret".toCharArray()
    )
);
MongoClient mongoClient = new MongoClient( seeds);  //, credentials );
MongoDbFactory mongoDbFactory = new SimpleMongoDbFactory(mongoClient, "zoo");

3 - 插入一行

mongoTemplate.insert(animal, "animal");

4 - 获取此错误（此代码在我不使用身份验证时有效）

Answer 1

稍微挖掘一下，我发现Mongo 3不喜欢挑战 - 反应并且更喜欢 MongoCredential.createScramSha1Credential ＆＃39;

List<ServerAddress> seeds = new ArrayList<ServerAddress>();
seeds.add( new ServerAddress( "remoteServer" ));
List<MongoCredential> credentials = new ArrayList<MongoCredential>();
credentials.add(
    MongoCredential.createScramSha1Credential(
        "username",
        "adminDatabase",
        "password".toCharArray()
    )
);
MongoClient mongoClient = new MongoClient( seeds, credentials );
MongoDbFactory mongoDbFactory = new SimpleMongoDbFactory(mongoClient, "applicationDatabase");
mongoTemplate = new MongoTemplate(mongoDbFactory);

Answer 2

当使用artefactId＆＃34; spring-boot-starter-data-mongodb＆＃34; MongoCredential.createScramSha1Credential 不可用。

所以这就是我必须要做的事情：

A）在 pom.xml 中包含对mongodb的maven依赖：

<dependency>
    <groupId>org.mongodb</groupId>
    <artifactId>mongo-java-driver</artifactId>
    <version>3.4.0</version>
</dependency>

B）使用user4898172的解决方案（ MongoCredential.createScramSha1Credential ）

public Mongo mongo() throws Exception {
    List<MongoCredential> credentials = new ArrayList<>();
    credentials.add(MongoCredential.createScramSha1Credential(username, database, password.toCharArray()));

    return new MongoClient(new ServerAddress(host, port), credentials);
}

这两个变化帮助我解决了Exeption：

com.mongodb.CommandFailureException：{＆＃34; serverUsed＆＃34; ：＆＃34; REMOTESERVER：27017＆＃34; ，＆＃34; ok＆＃34; ：0.0，＆＃34; errmsg＆＃34; ：＆＃34; auth失败＆＃34; ，＆＃34;代码＆＃34; ：18}

（我使用的是MongoDB服务器版本：3.4.0）

mongodb github site也是实施细节的一个很好的参考。

无法使用java连接在MongoDB 3.0.2中对用户进行身份验证
