Similar fields in DTO

Question

I want to create a DTO. The DTO will be used to map HTTP request to a REST webservice in spring. My controller looks like this:

RequestMapping( value = DmsRestSvcApi.DOCUMENT_SEARCH_PATH, method = RequestMethod.POST, produces = { MediaType.APPLICATION_JSON_VALUE } )
public List<DocSearchResponse> getDocumentInfoJson( @Validated @RequestBody DocSearchRequest oDocSearchRequest ) throws Exception {
    // do something
}

In the above signature the DocSearchRequest is the DTO I want to create. The DTO has some fields like:

private String searchCriteria1;
private String searchCriteria2;
/*
  .
  .
  .
 */
private String searchCriteria20;

// setters and getters.

Do we have a better way to implement the DTO? One thing to keep in mind is Spring uses reflection to set the values from the request to the DTO.

i can try that but not sure if spring will be able to map the request to the body using reflections. — Albert Pinto, Oct 05 '15 at 05:58
If you provide the values in the JSON as list, then it will be able to do that. — dunni, Oct 05 '15 at 08:19
You can use a `List` as @dunni suggested, or you can create a simple class containing private fields with public getters and setters, or you could also use a `Map` and use `get("searchCriteria1")` etc methods to get the values. — fps, Oct 05 '15 at 12:49
@dunni and Federico I implement a List and in my request i send my criteria as a coma separated. I all works as charm... thanks for the suggestion. — Albert Pinto, Oct 13 '15 at 00:45

A List of cafeterias solved the problem. I have to send the request as a comma separated value ans Spring takes care of mapping. Same can be done for the Response.

There is no business logic in DTO. It looks like you don't have too. It should represent the state of object . It should have private instance fields and their getters/setters. Basically should follow the encapsulation/abstraction.
