Connection String

mongodb://host:27017
mongodb://host1:27017,host2:27017

连到某个数据库

mongodb://host:27017/mydb
mongodb://host:27017/?replicaSet=rs0&maxPoolSize=200

使用mongoclient建立连接

MongoClient client = new MongoClient();
MongoClient client = new MongoClient(new MongoClientURI("mongodb://host:27017,host2:27017/?replicaSet=rs0"));

MongoClientOptions options = MongoClientOptions.builder().cursorFinalizerEnabled(false).build();
MongoClient client = new MongoClient(options);

MongoClientURI uri = new MongoClientURI("mongodb://host:27017,host2:27017/?replicaSet=rs0",
                                        MongoClientOptions.builder().cursorFinalizerEnabled(false))
MongoClient client = new MongoClient(uri);
