无法使用java连接在MongoDB 3.0.2中对用户进行身份validation

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 seeds = new ArrayList(); seeds.add( new ServerAddress( "remoteserver" )); List credentials = new ArrayList(); 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validation时有效）

Answer 1

稍微挖掘一下，我发现Mongo 3不喜欢挑战 – 反应并喜欢’ MongoCredential.createScramSha1Credential ‘

 List seeds = new ArrayList(); seeds.add( new ServerAddress( "remoteServer" )); List credentials = new ArrayList(); 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

当使用与artefactId“spring-boot-starter-data-mongodb”的maven依赖时， MongoCredential.createScramSha1Credential不可用。

所以这就是我必须做的事情：

A）在pom.xml中包含对mongodb的maven依赖：

  org.mongodb mongo-java-driver 3.4.0  

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

 public Mongo mongo() throws Exception { List 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：{“serverUsed”：“remoteserver：27017”，“ok”：0.0，“errmsg”：“auth failed”，“code”：18}

（我使用的是MongoDB服务器版本：3.4.0）

mongodb github站点也是实现细节的一个很好的参考。
