Dozer Function Improvment Suggestion

[朱国伟]

hi, 

    In recent development, I found dozer is not very convenient. My requirement described below:

query string (request.getParameterMap) --> DTO --> Domain Object.

1. Attribute names in DTO must as same as query param. For example,

query string:

?payment_code=12345678

DTO:

private String payment_code

2. if the Domain Object's attribute name is inconsistent with DTO's,eg.

Domain Object:

private String orderId;

So in this situation, you can't simply using @Mapping("orderId") in DTO for converting DTO to Domain Object successfully.Because if you do so, it will throw exception like this when you convert query params to DTO:

org.dozer.MappingException: No such field found java.util.HashMap.orderId

So after several unsuccessful attempts, finally I found a solution.

That is supply addtional getter/setter method in DTO, for example:

DTO

private String payment_code;

//getter and setter for payment_code here

//addtional getter and setter for successully converting to Domain Object

public String getOrderId(){return paymnet_code;}

public void setOrderId(){}

 Now query params --> DTO ok, and DTO-->Domain Object ok too.

But you know there are many params not only payment_code(e.g. service_id, user_id,credit_name,creadit_amount and so on),  so iot's terrible to add so many addtional getter/setter methods.

Apart from above, value of request.getParameterMap is string array, not string, so at first I have to covert this Map to common hashmap.

So can optimise dozer for this situation?
