Set Mongo Timeout in Spring Boot

Question

I am using spring boot web application which connects to mongo db which is working out of the box. I just use the following properties:

spring.data.mongodb.h         


        

Answer 1

For Spring Data with Reactive MongoDb:

My case was a bit different (I had closing connections - which throws "Caused by: java.lang.IllegalStateException: state should be: open")

But You can use this with your case.

application.yml:

spring.data.mongodb:
  host: localhost
  database: myDb
  port: 27017
  username: admin
  password: test

If Your implementation use MongoReactiveAutoConfiguration for bean creation, then You can configure it with this bean:

@Bean
public MongoClientSettings mongoClientSettings() {
    final MongoClientSettings clientSettings = MongoClientSettings.builder()
            .retryWrites(true)
            .applyToConnectionPoolSettings((ConnectionPoolSettings.Builder builder) -> {
                builder.maxSize(300) //connections count
                        .minSize(100)
                        .maxConnectionLifeTime(0, TimeUnit.MILLISECONDS)
                        .maxConnectionIdleTime(0, TimeUnit.MILLISECONDS)
                        .maxWaitTime(5000, TimeUnit.MILLISECONDS)
                        .maxWaitQueueSize(5000);
            })
            .applyToSocketSettings(builder -> {
                builder.connectTimeout(2000, TimeUnit.MILLISECONDS);
            })
            .applicationName("app")
            .build();

    return clientSettings;
}
