How can I use MapStruct to create a mapper that maps from Model entity that includes one list of objects and one another object to Domain entity, consists of only list of nested objects.

My Model entity list object = SourceObject-A;

My Model entity second object = SourceObject-B;

My Doamin entity list object = TargetObject-AB;

My source classes looks like this:

SourceObject-A:

I have Inventory class and InventoryResponse class.

I am learning to use MapStruct.

I have the following custom mapping configuration that maps a List comes from JPA entity to DTO String that way:

I'm currently setting up a MapStruct mapper with the Spring componentModel and so far everything works fine, the individual sub-mappers can be autowired and are injected as expected. However, using decorated mappers leads to the following failure when loading the ApplicationContext:

Error creating bean with name 'exampleMapperImpl': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type '...ExampleMapper' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Qualifier(value="delegate")}

I exactly followed the MapStruct documentation to decorate my mapper, which is why I'm confused as to why the setup is not working.

Here is my sample setup:

I have a Java class having 10 attributes, I want to convert this into 3 maps(Breaking it into 5,3,2 fields resepectively). I did some research and found that Jackson's ObjectMapper can be used by doing something like this:

How to resolve the following warning from the quarkus maven plugin?

Found unrecommended usage of private members (use package-private instead) in application beans

My code looks like this:

I have following structures

I've got project, where I often map dto -> db model. Almost all my db models have some additional fields, like version, which are never mapped from dto.

Is there any possibility or elegant workaround to ignore target fields globally only by theirs names?

For now I have to use @Mapping(target = "version", ignore = true). Cannot use @Mapper(unmappedTargetPolicy = ReportingPolicy.IGNORE), because I'd like to get warns or errors when I accidentally omit any important property. I control default behavior with '-Amapstruct.unmappedTargetPolicy=WARN', which I change for ERROR during developing new functions.

Some people may say that these are just warnings, but when there are many of them, it makes it harder to spot mistakes.

Mapstruct 1.3.1.Final, probably will move to 1.4.1.Final in nearest future. Searched through the docs, but couldn't find anything useful.

Thanks in advance for your answers :)
