@Component(value="blContentProcessor")
public class ContentProcessor
extends AbstractModelVariableModifierProcessor

Processor used to display structured content that is maintained with the Broadleaf CMS. Usage based on the following attributes:

• contentType (required) - specifies the content you are retrieving
• contentName - if included will retrieve only content that matches the name. When no name is specified, all matching content items of the passed in type are retrieved.
• maxResults - if specified limits the results to a specified number of items. The content will be returned according to priority. If content items share the same priority, then they will be returned randomly. Consider the example with 5 matching items with priorities (1,2,3,3,3) respectively. If the count is set to 3. Items 1 and 2 will ALWAYS be returned. The third item returned will randomy rotate through the 3rd, 4th, and 5th item.
• contentListVar - allows you to specify an alternate name for the list of content results. By default, the results are returned in the page attributed "contentList"
• contentItemVar - since a typical usage is to only return one item, the first item is returned in the variable "contentItem". This variable can be used to change the attribute name.
• numResultsVar - variable holding the returns the number of results being returned to through the tag-lib. defaults to "numResults".
• fieldFilters - Thymeleaf key-value pair to filter the resulting StructuredContentDTO by particular field values. For instance, if you had a field in a piece of structured content called 'featured' and you wanted to return all of the featured content items, you could do the following:
