Frans Thamura commented on WW-3629:
-----------------------------------
glad our code can be part of the struts2.. http://cimande.java.net
the jackson is cool, because implement JSONFactory, that will give us benefit.
NB: I prefer JPA with JSON rather current Hibernate :)

> Provide a JSON Content Handler based on Jackson Lib
> ---------------------------------------------------
>
> Key: WW-3629
> URL: https://issues.apache.org/jira/browse/WW-3629
> Project: Struts 2
> Issue Type: Improvement
> Components: Plugin - REST
> Reporter: Johannes Geppert
> Assignee: Johannes Geppert
> Priority: Minor
> Labels: handler, json
> Original Estimate: 4h
> Remaining Estimate: 4h
>
> Provide a JSON Content Handler based on Jackson Lib:
> http://jackson.codehaus.org/
> Jackson is a:
> Streaming (reading, writing)
> FAST (measured to be faster than any other Java json parser and data
> binder)
> Powerful (full data binding for common JDK classes as well as any Java
> bean class, Collection, Map or Enum)
> Zero-dependency (does not rely on other packages beyond JDK)
> Open Source (LGPL or AL)
> Fully conformant
> Extremely configurable
> JSON processor (JSON parser + JSON generator) written in Java. Beyond basic
> JSON reading/writing (parsing, generating), it also offers full node-based
> Tree Model, as well as full OJM (Object/Json Mapper) data binding
> functionality.
> A Content Handler can look like this:
> import java.io.IOException;
> import java.io.Writer;
> import org.codehaus.jackson.JsonGenerationException;
> import org.codehaus.jackson.map.JsonMappingException;
> import org.codehaus.jackson.map.ObjectMapper;
> import org.codehaus.jackson.map.SerializationConfig.Feature;
> public class JsonContentHandler implements ContentHandler {
> public void fromObject(Object object, Writer writer) {
> try {
> ObjectMapper objectMapper = new ObjectMapper();
> objectMapper.configure(Feature.WRITE_NULL_MAP_VALUES,
> false);
> objectMapper.writeValue(writer, object);
> } catch (JsonGenerationException e) {
> e.printStackTrace();
> } catch (JsonMappingException e) {
> e.printStackTrace();
> } catch (IOException e) {
> e.printStackTrace();
> }
> }
> public String getContentType() {
> return "application/json";
> }
> public String getExtension() {
> return "json";
> }
> }
