It’ my pleasure to announce the first Beta release of MapStruct 1.4.
The new release comes with a whole lot of new functionality, e.g.:
- Making use of constructor arguments when instantiating mapping targets
- Support Gradle incremental annotation processing feature
- Map nested bean properties to current target
- Support value mapping between
@Mapping in meta annotations
- User control over mapping features (direct, method, conversion, 2step)
- Support mapping from / to Java 14 records (preview feature)
Lately, we have been busy working on the release of MapStruct 1.4, adding new features and trying to
simplify our codebase so we can maintain it easier and add features faster.
From the start of the project we have been using a utility tool Hickory
for generating Prisms (partial reflection access to annotations) during compilation time.
Basically, we’ve been using an annotation processor to generate access to the MapStruct annotations,
this allows us to access the MapStruct annotation in a type-safe way, without requiring the annotation JAR to be on the processor path.
This is a really old project and the only release on Maven Central is from March 2010.
Thus we needed something newer and created our own utility.
Say hi to Gem Tools.
This year is nearly over, but it was started with something new that came up in the Java world: Quarkus. You may already have heard about it, if not, don’t worry, I will quickly summarize what it is.
Additionally to this post you can also find a working example in our examples repository.
It is my pleasure to announce the 1.3.1.Final bug fix release of MapStruct.
Since the Final release of MapStruct 1.3.0.Final we have received amazing feedback from the community.
This release includes 3 enhancements, 12 bug fixes and 7 documentation improvements.
The enhancements include:
- Ability to disable builders on method level via
- Stricter matching for lifecycle methods / non-unique parameters
Long overdue it is our pleasure to announce the final version MapStruct 1.3.
This is our 3rd release since november 2015.
Besides bug fixes, the 1.3 release brings some new exciting features:
- Mapping (immutable) objects using builders
- Enhanced and more flexible update method (
- Constructor injection for Annotation Based component models
- Source policy for unmapped source properties (
- Support for
- Limit mapping only to explicitly defined mappings
- Performance improvement of
defaultValue primitive to
- Warnings for precision loss
