Может ли Mapstruct сделать частичное обновление записей? ⇐ JAVA

[Anonymous]

Я поверил в код Intellij's Code AI, что Mapstruct может сделать частичное обновление записи Java. PrettyPrint-Override ">public record Example(Long id, String name){}

public record ExampleWithBuilder(Long id, String name) {
public static ExampleWithBuilderBuilder builder() {
return new ExampleWithBuilderBuilder();
}

public static class ExampleWithBuilderBuilder {
private Long id;
private String name;

ExampleWithBuilderBuilder() {
}

public ExampleWithBuilderBuilder id(Long id) {
this.id = id;
return this;
}

public ExampleWithBuilderBuilder name(String name) {
this.name = name;
return this;
}

public ExampleWithBuilder build() {
return new ExampleWithBuilder(this.id, this.name);
}

public String toString() {
return "ExampleWithBuilder.ExampleWithBuilderBuilder(id=" + this.id + ", name=" + this.name + ")";
}
}
}

@Mapper(unmappedTargetPolicy = ReportingPolicy.IGNORE, componentModel = MappingConstants.ComponentModel.SPRING)
public interface RacerMapper {
@BeanMapping(nullValuePropertyMappingStrategy = NullValuePropertyMappingStrategy.IGNORE)
void partialUpdate(ExampleWithBuilder exampleWithBuilder, @MappingTarget Example example);

@BeanMapping(nullValuePropertyMappingStrategy = NullValuePropertyMappingStrategy.IGNORE)
ExampleWithBuilder partialUpdate(Example example, @MappingTarget ExampleWithBuilder exampleWithBuilder);
}
< /code>
Сгенерированный код показывает, что только возвращает MappingTarget < /p>
@Override
public Example partialUpdate(ExampleWithBuilder exampleWithBuilder, Example example) {
if ( exampleWithBuilder == null ) {
return example;
}

return example;
}

@Override
public ExampleWithBuilder partialUpdate(Example example, ExampleWithBuilder exampleWithBuilder) {
if ( example == null ) {
return exampleWithBuilder;
}

return exampleWithBuilder;
}

< /code>
pom.xml зависимость < /p>
