Spring MVC: jackson-mapper-asl not work with Spring 4

Question

I am trying to convert List of objects into json with the help of jackson-mapper-asl libraries, but in response i got http 406 error. jackson-mapper-asl libraries are on my class path. Following is my Spring MVC controller code:

@RequestMapping(value="/find-sub-categories/{parentId}", method=RequestMethod.GET)
@ResponseBody public List<ProductCategory> findSubCategories(@PathVariable(value="parentId") ProductCategory productCategory) {
    logger.info("In ADMIN findSubCategories Contoller AJAX GET");

    List<ProductCategory> categories = productCategoryService.findAllChildProductCategoriesByParent(productCategory);
    return categories;
}

My Ajax request code:

$.ajax({
            url: url+"/"+parentId,
            type: 'GET',
            success: function(result) {
                var arr = $.parseJSON(result);

Answer 1

With spring 4, we need to use following dependency:

<dependency>
 <groupId>com.fasterxml.jackson.core</groupId>
 <artifactId>jackson-databind</artifactId>
 <version>2.5.1</version>
</dependency>

The jackson-mapper-asl is used with spring 3.x. Thanks to @Master Slave for valid comment. Click here for more information: Spring 4 RestController JSON: characteristics not acceptable according to the request "accept" headers
