Hibernate Streams

A JDK 8 wrapper on top of Hibernate Query API

Features

• Retrieval of Optional query results
• Query to stream conversion
• Typed queries

Current compatibility: Hibernate 4.3.x / Hibernate 5.x

See the document that summarizes the introduced API changes

Setup

In order to start and running simply add the artifact to your Maven/Gradle build.

<dependency>
    <groupId>com.github.jmnarloch</groupId>
    <artifactId>hstreams43</artifactId>
    <version>1.0.2</version>
</dependency>

Example

SessionFactory originalFactory = ...;

StreamSessionFactory factory = Streams.wrap(originalFactory);
StreamSession session = factory.getCurrentSession();

long count = session.createQuery("from User")
        .stream()
        .count();

Optional<User> admin = session.createTypedQuery("from User where id = :id", User.class)
        .setParameter("id", 1l)
        .stream()
        .findFirst();

Optional<User> user = session.getOptional("User", 1l);

Todo

• LocalDate and LocalTime support - will be natively supported through Hibernate 5
• Optional<?> custom type handler/converter
