mapping an object to a list of objects using spring

[declan roche]

Hi ,

I wonder if you can help me.

I am trying to map an object A to a list of object B

I have a mapper which maps from object A to object B

 

I Have tried a number of different ways for example

Trying to create a list with one object A using expressions

And qualifiedByName but this does not work because I think

Because when you use expressions/qualifiedByName you can not use

Custom mappers ( I could be wrong here ?)

 

I also tried to call the mapper from the @aftermapper method using

The mappers.getMapper to get a handle on the target mapper

But I found that the spring beans used in the mapper

Where not being populated. Mapping in the aftermapping makes

Sense in that I can create a list and put my object into it

Before passing to the mapper. So I am hoping that there is another

Way to get a handle on the mapper component from my mapper.

 

All my mappers use

@Mapper(componentModel="spring",

 

All suggestions are welcome

 

Regards,

Declan

 

 

// SPECIESTOLOGSPECY.JAVA

// From this mapper I want to call SpecyToLogDeclarationMapperApi mapper

// to map ‘species’ to ‘logdeclarations’ which is a list of logdeclaration

// you can see want I am trying to do in the aftermapping method

// where I map species to logdeclaration and then put this into a list

// unfortunately I need other mapping components to be autowired into

//  SpecyToLogDeclarationMapperApi and this is not happening.

// is there another way to get a handle to the spring managed

// SpecyToLogDeclarationMapperApi mapper ?

Hey Declan,

I've answered your question on StackOverflow. here is my answer.

In a nutshell, you are missing a method that would map from Species to List<Logdeclaration>

Cheers,

Filip
