Quick Start

Connect DriverMongoExecutionContext and MongoTemplateResolver, and execute the first query of Reactive Mongo DSL 1.0.0.

1. MongoExecutionContext Configuration

MongoConfig.java

java

The default DriverMongoExecutionContext directly uses the MongoDB Reactive Streams Driver. If the collection naming conventions differ, a separate collection-name resolver can be provided.

2. MongoTemplateResolver Connection

MongoTemplateNameResolver.java

java

What the resolver returns is a MongoExecutionContext.

In version 1.0.0, MongoTemplateResolver#getTemplate(...) returns a MongoExecutionContext corresponding to the key, not a ReactiveMongoTemplate or Spring transaction object.

3. First query

UserService.java

java

Null dynamic conditions will be skipped in the condition list.

You can pass a condition ? pair(...) : null form to fields(...). This is unrelated to emitting null in a Reactor publisher.

When used as a Spring Bean

ReactiveMongoDslConfiguration.java

java

Spring Integration

Check the Spring Data mapping/auditing adapter configuration.

Query Flow

Compare the entry flows of general queries, root aggregation, and Search/Vector.
