modelmapper

问题 I'm trying to use ModelMapper for mapping source to destination. In my specific case, in the source class there is a property (List of Review), where I have to sum by rating and set this value to destination class. So I've tried with converter, but it doesn't working. Converter<List<Review>, Double> sumReviewsRating = new AbstractConverter<List<Review>, Double>() { @Override protected Double convert(List<Review> reviews) { if(reviews!=null){ return reviews.stream().mapToDouble(Review:

问题 I have two classes say Animal & AnimalDto I want to use ModelMapper to convert Entity to DTO and vice verca. But the classes are supposed to have different data types for a few attributes having similar name. How do I achieve this? Animal.java public class Animal { int category; String color; int age; } AnimalDto.java public class AnimalDto { String category; int color; int age; } currently I'm manually transforming as such: class AnimalTransformer { private static Category[] categories =

问题 Hey I just began playing around with Modelmapper to map jOOQ records to POJOs. This is the schema for the table whose records I am attempting to convert (Postgresql) CREATE TABLE IF NOT EXISTS actor( actor_id UUID DEFAULT uuid_generate_v4(), first_name VARCHAR(256) NOT NULL, last_name VARCHAR(256) NOT NULL, PRIMARY KEY(actor_id) ); Here is what the POJO looks like: @JsonDeserialize(builder = Actor.Builder.class) public class Actor { private final UUID actorId; private final String firstName;

问题 How can I read read the value of a Java method annotation at runtime with ASM ? The Annotation has only a CLASS RetentionPolicy , so it's not possible to do that with Reflections. | Policy CLASS : Annotations are to be recorded in the class file by the compiler but need not be retained by the VM at run time Example : I want to extract the value Carly Rae Jepsen out of the artist field at runtime: public class SampleClass { @MyAnnotation(artist = "Carly Rae Jepsen") public void callMeMaybe(){}
