Speedment accelerates your development speed and makes programming so easy and fun!
When you use Speedment for database querying, you do not have to learn a new APIs or use complex ORMs. Everything is standard Java 8 and works out of the box!
This site covers the Speedment Open Source project available under the Apache 2 license. If you are interested in the enterprise product with support for commercial databases and in-memory acceleration, check out www.speedment.com!
You can read the the API quick start here!

Here are a few examples of how you could use Speedment from your code:
A HareApplication
class is generated from the database.
Speedment speedment = new HareApplication().withPassword("myPwd729").build();
Manager<Hare> hares = speedment.managerOf(Hare.class);
Search for Hares by a certain age:
// Searches are optimized in the background!
Optional<Hare> harry = hares.stream()
.filter(NAME.equal("Harry").and(AGE.lessThan(5)))
.findAny();
Results in the following SQL query:
SELECT * FROM `Hare`
WHERE `Hare`.`name` = "Harry"
AND `Hare`.`age` < 5
LIMIT 1;
Entities can be persisted in a database using the "Active Record Pattern"
Hare dbHarry = hares.newInstance()
.setName("Harry")
.setColor("Gray")
.setAge(3)
.persist();
Hare harry = hares.newInstance()
.setName("Harry")
.setColor("Gray")
.setAge(3);
Hare dbHarry = EntityManager.get(speedment).persist(harry);
No need for complicated joins!
Optional<Carrot> carrot = hares.stream()
.filter(NAME.equal("Harry"))
.flatMap(Hare::findCarrots) // Carrot is a foreign key table.
.findAny();
// List all hares in JSON format
hares.stream()
.map(Hare::toJson)
.forEach(System.out::println);
// List all hares as one JSON object
String json = hares.stream()
.collect(CollectorUtil.toJson());
Here are some of the many features packed into the Speedment framework!
Speedment is using the database as the source-of-truth, both when it comes to the domain model and the actual data itself. Perfect if you are tired of configuring and debuging complex ORMs. After all, your data is more important than programming tools, is it not?
Speedment inspects your database and can automatically generate code that reflects the latest state of your database. Nice if you have changed the data structure (like columns or tables) in your database. Optionally, you can change the way code is generated using an intuitive UI or programatically using your own code.
Speedment is built with the ambition to be completely modular! If you don't like the current implementation of a certain function, plug in you own! Do you have a suggestion for an alternative way of solving a complex problem? Share it with the community!
When the database structure changes during development of a software there is always a risk that bugs sneak into the application. Thats why type-safety is such a big deal! With Speedment, you will notice if something is wrong seconds after you generate your code instead of weeks into the testing phase.
Ever seen a NullPointerException
suddenly casted out of nowhere? Null-pointers have been called the billion-dollar-mistake of java, but at the same time they are used in almost every software project out there. To minimize the production risks of using null values, Speedment analyzes if null values are allowed by a column in the database and wraps the values as appropriate in Java 8 Optionals.
To use Speedment, just add the following lines (between the ... marker lines) to your project's pom.xml
file.
