Custom JsonSerialize with DateObject not working

[prakash290]

Custom Serialize for Date Object Class is not working.

POJO Class :

public class Client {
	
	@Id
	@GeneratedValue(strategy=GenerationType.SEQUENCE,generator="Client")		
	private Integer client_id;

      @JsonSerialize(using=JacksonDateTimeSerializer.class)	
	public Date getCreation_date() {
		return creation_date;
	}

}

JacksonDateTimeSerializer Class

@Component
public class JacksonDateTimeSerializer extends StdSerializer<Date>{
	
	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	private SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
		 
		    public JacksonDateTimeSerializer() {
		        this(null);
		    }
		 
		    @SuppressWarnings({ "rawtypes", "unchecked" })
			public JacksonDateTimeSerializer(Class t) {
		        super(t);
		    }
		     
		    @Override
		    public void serialize (Date value, JsonGenerator gen, SerializerProvider arg2)
		      throws IOException, JsonProcessingException {
		    	System.out.println("Am Executing");
		        gen.writeString(formatter.format(value));
		    }
}

    @Bean(name="ObjectMapper")
	public ObjectMapper objectMapper()
	{
		return new ObjectMapper();
	}
	
	@Bean(name="jsonViewObjectMapper")
	public ObjectMapper jsonViewObjectMapper()
	{
		ObjectMapper mapper = new ObjectMapper();
    	SimpleModule module = new SimpleModule();
    	module.addSerializer(JsonView.class, new JsonViewSerializer());    	
    	mapper.registerModule(module);
    	return mapper;
	}

Using ObjectMapper instance I can able to Serialize Date using JacksonDateTimeSerializer class.
But using jsonViewObjectMapper instance i can't Serialize using JacksonDateTimeSerializer class.

How to use custom Serialize class for Date object ?

Support for this was added in #35, but not well documented or exposed. I added a simpler method for registering custom serializers through the Jackson Module class in the latest unreleased code. If you'd like to try this out to see if it works for you, clone the latest code in master and install it locally

It's working fine for single java object custom serialize class.

How to add two custom serialize class for Date object ?
How to use those class dynamically for single pojo properties?

Lets I have Pojo called Client and two date properties.

public class Client {	

      @JsonSerialize(using=JacksonDateTimeSerializer.class)	
       private Date creationDate;
      
      @JsonSerialize(using=JacksonDateSerializer.class)	
       private Date quoteDate;     
}

I want to serialize both properties but using different custom serialize class. So how to do it?

[monitorjbl]

Currently, this isn't supported. I'll get that added in though, the long-term goal for this library is full support of all field-level annotations.

@prakash290 I added this to the latest code in master. Give it a try locally and let me know if it works for you.

Thanks @monitorjbl . It works fine

@monitorjbl when is this going to be released? Great library btw just the Date formats are not very nice.

[monitorjbl]

Probably in the next week or so. Date formats in Excel are arcane and bizarre, so dealing with them can be tricky.

[afish8ben]

Sounds good and I can't agree enough Date formats can be a pain!
I just used your spring library instead and returned the object to let Jackson handle my date on response.
