# Object-to-object mapping framework microbenchmark #
2+
3+
Multi-layered applications often require to map between different object models (e.g. DTOs and entities).
4+
Writing such boiler plate mapping code is a tedious and error-prone task.
5+
A lot of object-to-object mapping Java frameworks aims to simplify this work and automate it.
6+
Some uses code instrospection (eg. Dozer). Other uses code generation (ex: MapStuct).
7+
This micro-benchmark compares performance of 5 frameworks. Results could be compared to the benchmark of a code written manually.
8+
9+
Benchmark are powered by a tool called [JMH](http://openjdk.java.net/projects/code-tools/jmh/) or also known as "Java Microbenchmarking Harness".
10+
JMH is developed by the OpenJDK team.
11+
12+
## Benchmarked object to object mapper frameworks ##
13+
14+
- [Dozer](https://github.com/DozerMapper/dozer)
15+
- [MapStruct](http://mapstruct.org/)
16+
- [ModelMapper](http://modelmapper.org/)
17+
- [Selma](http://www.selma-java.org/)
18+
- [Orika](https://github.com/orika-mapper/orika)
19+
20+
## Contributing to benchmark ##
21+
22+
23+
Github is for social coding platform: if you want to add another mapping framework or optimize an existing one, we encourage contributions through pull requests from [forks of this repository](http://help.github.com/forking/). If you want to contribute code this way, please reference a GitHub ticket as well covering the specific issue you are addressing.
24+
25+
26+
## Data model ##
27+
28+
The data model used by this benchmark is very basic. It comes from the [Comparison](https://github.com/jhalterman/modelmapper/blob/master/core/src/test/java/org/modelmapper/performance/Comparison.java) class from the ModelMapper framework.
29+
It includes combinations which usually appear in Java Beans, such as:
30+
31+
* Object types
32+
* Collections
33+
34+
35+
## Launch the benchmark ##
36+
37+
_Pre-requisites: Maven 3.x and a JDK 6 (or above)_
38+
39+
``git clone git://github.com/arey/java-object-mapper-benchmark.git``
40+
41+
``mvn clean install``
42+
43+
``java -jar target/benchmarks.jar``
44+
45+
## Results ##
46+
47+
Tests has been performed on:
48+
49+
* OS: MacOSX
50+
* CPU: Core i7 2.8GHz 6MB cache × 4 cores
51+
* RAM: 16GB
52+
* JVM: Oracle 1.8.0_25 64 bits
