# MongoDB Consumer A consumer that allows you to insert records into MongoDB. ## Beans for injection You can import `MongoDbConsumerConfiguration` in the application and then inject one of the following beans. `Function<Message<?>, Mono<Void>> mongodbConsumerFunction` - Allows you to subscribe. `Consumer<Message<?>> mongodbConsumer` - Wraps the function as a Consumer with no-op subscriber. You can use `mongodbConsumer` or `mongodbConsumerFunction` as a qualifier when injecting. The return value from the function can be ignored as this is used as a consumer to send records to MongoDB. ## Configuration Options All configuration properties are prefixed with `mongodb.consumer`. For more information on the various options available, please see link:src/main/java/org/springframework/cloud/fn/consumer/mongo/MongoDBConsumerProperties.java[MongoDBConsumerProperties]. ## Examples See this link:src/test/java/org/springframework/cloud/fn/consumer/mongo/MongoDBConsumerApplicationTests.java[test suite] for the various ways, this consumer is used. ## Other usage See this https://github.com/spring-cloud/stream-applications/blob/master/applications/sink/mongodb-sink/README.adoc[README] where this consumer is used to create a Spring Cloud Stream application where it makes a MongoDB sink.
