개요

이 섹션에서는 Java Reactive Streams 운전자 에서 연결 URI의 매개변수로 전달할 수 있는 MongoDB 연결 및 인증 옵션에 대해 설명합니다.

연결 URI 사용

연결 URI를 MongoClient 생성자에 전달하는 경우 string 에 연결 옵션을 <name>=<value> 쌍으로 포함할 수 있습니다. 다음 예시 에서 연결 URI에는 값이 60000 인 connectTimeoutMS 옵션과 값이 true 인 tls 옵션이 포함되어 있습니다.

public class MongoConnection {
public static void main(String[] args) {
    String uri = "mongodb://<hostname>:<port>/?connectTimeoutMS=60000&tls=true";
    try (MongoClient client = MongoClients.create(uri)) {
            // Use client here
        }
    }
}

연결 옵션

다음 섹션에서는 Java Reactive Streams 운전자 에서 사용할 수 있는 연결 옵션에 대해 설명합니다. 이러한 옵션을 연결 URI의 매개 변수로 전달하여 클라이언트 의 동작을 지정할 수 있습니다.

인증

연결 옵션
설명
authMechanism
Sets the mechanism the Java Reactive Streams driver uses to authenticate the
application. Valid options are defined in the Class ConnectionString API documentation.

Data Type: String
Default: "SCRAM-SHA-256" when connecting to MongoDB v4.0 or later.
"SCRAM-SHA-1" when connecting to MongoDB v3.0 through v3.13.

authMechanismProperties
Sets options specific to the authentication mechanism.

Data Type: String
Default: ""
Connection URI Example: authMechanismProperties=AWS_SESSION_TOKEN:12435
authSource
Sets the source of authentication credentials. The source is typically a
database. This option is only respected when authMechanism is set
to MONGO-CR.

Data Type: String
Default: The database in the connection URI, or "admin" if none is provided
Connection URI Example: authSource=admin
사용자 이름
Sets the username for authentication. When this option is included in a connection
URI, you must percent-escape it.

URI, you must percent-escape it.

Data Type: String
Default: ""

an in-use connection becomes available or a connection is created and
starts becoming established.

Default: null
Connection URI Example: waitQueueTimeoutMS=6000

CompressorConfiguration

연결 옵션
설명
압축기
Sets preferred compression types, in order, for wire-protocol messages sent to
or received from the server. Compression types must be passed in as a
comma-separated list. The driver uses the first of these compression types
that the server supports.

Data Type: String
Default: null
Connection URI Example: compressors=snappy,zstd,zlib
zlibCompressionLevel
Sets the compression level for zlib to use. This option accepts
an integer value between -1 and 9:

- -1: (Default). zlib uses its default compression level (usually 6).
- 0: No compression.
- 1: Fastest speed but lowest compression.
- 9: Best compression but slowest speed.

Data Type: Integer
Default: -1
Connection URI Example: zLibCompressionLevel=3
