Test:
@Test
public void testDozerMapping() {
ProductService productService = new ProductService(null);
HashMap<String, Object> input = new HashMap<String, Object>();
input.put("id", 54);
List<ProductSummary> products = productService.mapProducts(new Map[]{ input });
assertEquals(54, products.get(0).getId());
}
Mapping file (doesn't have effect whether it's used or not):
<?xml version="1.0" encoding="UTF-8"?>
<mappings xmlns="http://dozer.sourceforge.net" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://dozer.sourceforge.net
http://dozer.sourceforge.net/schema/beanmapping.xsd">
<mapping map-id="ProductSummary">
<class-a>id.co.bippo.magento.domain.ProductSummary</class-a>
<class-b>java.util.Map</class-b>
<field><a>id</a><b>product_id</b></field>
<field><a>setId</a><b>set</b></field>
<field><a>categoryIds</a><b>category_ids</b></field>
</mapping>
</mappings>
Mapper usage :
public List<ProductSummary> mapProducts(Object input) {
DozerBeanMapper mapper = new DozerBeanMapper(Arrays.asList( new String[]{ "id/co/bippo/magento/api/dozer-mapping.xml"} ));
Map<String, Object>[] response = (Map<String, Object>[]) input;
ArrayList<ProductSummary> result = new ArrayList<ProductSummary>();
for (Map<String, Object> row : response) {
ProductSummary product = mapper.map(row, ProductSummary.class, "ProductSummary");
result.add(product);
}
return result;
}

I've completed branch : https://github.com/ceefour/dozer/tree/bug-3404162-classldr
which is a bugfix of this issue.
Please merge this patch.
BTW,
I propose to move dozer from Sourceforge SVN to GitHub. To facilitate contributions easily.
Please consider. Thank you.
