mongo-jackson-codec

Mongo Codec using Jackson (and bson4jackson) for serialization

Usage

Synchronous driver

CodecRegistry codecRegistry = CodecRegistries.fromRegistries(MongoClient.getDefaultCodecRegistry(),
                                                             CodecRegistries.fromProviders(new JacksonCodecProvider(ObjectMapperFactory.createObjectMapper())));

MongoClientOptions clientOptions = MongoClientOptions.builder()
                                                 .codecRegistry(codecRegistry)
                                                 .build();

MongoClient client = new MongoClient(new ServerAddress(), clientOptions);

MongoCollection<BlogPost> blogPosts = client.getDatabase("blog").getCollection("posts", BlogPost.class);

BlogPost blogPost1 = new BlogPost("/first_blog",
                              asList(new BlogPostComment(1, "First Comment"), new BlogPostComment(2, "Second Comment")));

BlogPost blogPost2 = new BlogPost("/second_blog",
                              asList(new BlogPostComment(2, "First Comment"), new BlogPostComment(2, "Second Comment")));

blogPosts.insertMany(asList(blogPost1, blogPost2));

List<BlogPost> allBlogPosts = blogPosts.find().into(new ArrayList<>());

Asynchronous driver

MongoClient client = MongoClients.create();

CodecRegistry codecRegistry = CodecRegistries.fromRegistries(
        MongoClients.getDefaultCodecRegistry(), CodecRegistries.fromProviders(
                new ObjectCodecProvider(ObjectMapperFactory.createObjectMapper())));

MongoDatabase database = client.getDatabase("blog").withCodecRegistry(codecRegistry);

MongoCollection<BlogPost> blogPosts = database.getCollection("posts", BlogPost.class);

BlogPost blogPost1 = new BlogPost("/first_blog",
        asList(new BlogPostComment(1, "First Comment"), new BlogPostComment(2, "Second Comment")));

BlogPost blogPost2 = new BlogPost("/second_blog",
        asList(new BlogPostComment(2, "First Comment"), new BlogPostComment(2, "Second Comment")));

blogPosts.insertMany(asList(blogPost1, blogPost2), new SingleResultCallback<Void>() {
    @Override
    public void onResult(Void aVoid, Throwable throwable) {

    }
});

blogPosts.find().into(new ArrayList<>(), new SingleResultCallback<ArrayList<BlogPost>>() {
    @Override
    public void onResult(ArrayList<BlogPost> blogPosts, Throwable throwable) {

    }
});

Mapping

If you want to have ObjectId represented as String, annotate your field with @Id
