Change path fastdl-mongodb

[ShimonMimoun]

Hello everyone,

I'm using Java 17 and Spring 3. I would like to change the download path for the MongoDB version to a different link.

Let me explain my issue. I am working in an environment where access to the external server is limited.

Previously, I used this solution, but it no longer works.

@Bean public DownloadConfigBuilderCustomizer downloadCustomizer() { DistributionDownloadPath downloadPath = new SameDownloadPathForEveryDistribution(DOWNLOAD_PATH); return downloadConfigBuilder -> { downloadConfigBuilder.downloadPath(downloadPath); downloadConfigBuilder.userAgent(USER_AGENT); }; }

Do you have any ideas on how to proceed?

@ShimonMimoun You can change the server for the download to a local one: https://github.com/flapdoodle-oss/de.flapdoodle.embed.mongo/blob/main/docs/Howto.md#customize-download-url

.. but as you are using spring you may apply this customization this way: https://github.com/flapdoodle-oss/de.flapdoodle.embed.mongo.spring/blob/main/HowTo.md#customize-mongod

.. feel free to ask if you struggle with anything:)

@ShimonMimoun there are more ways to customize this.. but this is maybe the easiest one.. i think i should add some documentation for this kind of problem ...

Thank you for your response. I have already tried that, but it still tries to connect to the main Atlas server. Can you guide me on how to do this? I tried modifying the mongod builder, but I wasn't successful. Could you please enlighten me on how to accomplish this?

@ShimonMimoun can you show me some code?

    @Bean
    public Mongod mongoConfiguration() {
        return Mongod.builder()
                .distributionBaseUrl(Start.to(DistributionBaseUrl.class)
                        .initializedWith(DistributionBaseUrl.of(DOWNLOAD_PATH)))
                .build();
    }

    @Bean
    public MongoClient mongoConfiguration(){
        return MongoClients.create(
                new MongoClientOptions.Builder()
                        .setDownloadUrl(DOWNLOAD_PATH)
                        .build());

    }

@ShimonMimoun you have to use a BeanPostProcessor to do this as in https://github.com/flapdoodle-oss/de.flapdoodle.embed.mongo.spring/blob/main/HowTo.md#customize-mongod

.. you can not define just a bean for that because things are a little bit complicated as you see here: https://github.com/flapdoodle-oss/de.flapdoodle.embed.mongo.spring/blob/374ef6bce27ce7ec8a7c889b71c4b192456db8c7/src/main/java/de/flapdoodle/embed/mongo/spring/autoconfigure/EmbeddedMongoAutoConfiguration.java#L191

I have found the solution, and I'm sharing it with you.

@Bean
BeanPostProcessor customizeMongod() {
    return TypedBeanPostProcessor.applyBeforeInitialization(Mongod.class, src ->
            Mongod.builder()
                    .from(src)
                    .distributionBaseUrl(
                            Start.to(DistributionBaseUrl.class)
                                    .initializedWith(DistributionBaseUrl.of(DOWNLOAD_PATH))
                    )
                    .build());
}

Thanks for your help @michaelmosmann
