I need to pass Localdate as part of the Ajax response to jquery datatables. LocalDate field does not display its value. Instead it prints [object,Object]. Obviously, it means LocalDate was not deserialized. Can some one please explain how to deserialize Localdate to display it properly.
Below is my Jquery Code:
var table = $("#example").DataTable({
"bProcessing" : true,
"bServerSide" : true,
"sAjaxSource" : "jsonSource.web",
"aoColumns" : [
{
"mData" : "name"
}, {
"mData" : "position"
}, {
"mData" : "office"
}, {
"mData" : "phone"
}, {
"mData" : "salary"
}, {
"mData" : "dob"
}
],
columnDefs : [ {
targets : [ 5 ],
render : function(data, type, row) {
var json = JSON.stringify(data);
var date = JSON.parse(json);
console.log("json: " + json + "date : " + row);
return data;
}
}
} ]
});
Server Side code:
#RequestMapping(value = "/springPaginationDataTables.web", method = RequestMethod.GET, produces = "application/json")
public #ResponseBody String springPaginationDataTables(HttpServletRequest request) throws IOException {
//Fetch search parameter
String searchParameter = request.getParameter("sSearch");
final String sortColumn = request.getParameter("iSortCol_0");
final String sortOrder = request.getParameter("sSortDir_0");
//Fetch Page display length
Integer pageDisplayLength = Integer.valueOf(request.getParameter("iDisplayLength"));
//Fetch the page number from client
Integer pageNumber = 0;
if (null != request.getParameter("iDisplayStart"))
pageNumber = (Integer.valueOf(request.getParameter("iDisplayStart"))/pageDisplayLength)+1;
System.out.println("sSearch : "+searchParameter);
System.out.println("pageDisplayLength : "+pageDisplayLength);
System.out.println("pageNumber : "+pageNumber);
System.out.println("iSortCol_0 : "+sortColumn);
System.out.println("sSortDir_0 : "+sortOrder);
List<Person> personsList = new ArrayList<Person>();
Person person2 = new Person();
person2.setName("John Landy");
person2.setPosition("System Architect");
person2.setSalary("$320,800");
person2.setOffice("NY");
person2.setPhone("999999999");
person2.setStart_date("05/05/2010");
person2.setDob(LocalDate.parse("1989-07-09"));
personsList.add(person2);
//apply server side search
//apply server side sort
//BuildDataTable object
PersonJsonObject personJsonObject = new PersonJsonObject();
//Set Total display record
personJsonObject.setiTotalDisplayRecords(500);
//Set Total record
personJsonObject.setiTotalRecords(500);
personJsonObject.setAaData(personsList);
Gson gson = new GsonBuilder().setPrettyPrinting().create();
String json2 = gson.toJson(personJsonObject);
return json2;
}
I solved it. had to extend SimpleModule from codehaus to implement serialisation/deserialisation for LocalDate. Below is my code:
public class LocalDateSimpleModule extends SimpleModule{
public LocalDateSimpleModule(String name, Version version) {
super(name, version);
addSerializer(LocalDate.class, new JsonSerializer<LocalDate>() {
#Override
public void serialize(LocalDate value, JsonGenerator jgen, SerializerProvider provider) throws IOException, JsonProcessingException {
ToStringSerializer.instance.serialize(value, jgen, provider);
}
});
addSerializer(LocalDateTime.class, new JsonSerializer<LocalDateTime>() {
#Override
public void serialize(LocalDateTime value, JsonGenerator jgen, SerializerProvider provider) throws IOException, JsonProcessingException {
ToStringSerializer.instance.serialize(value, jgen, provider);
}
});
addDeserializer(LocalDate.class, new JsonDeserializer<LocalDate>() {
#Override
public LocalDate deserialize(JsonParser jp, DeserializationContext ctxt) throws IOException, JsonProcessingException {
return LocalDate.parse(jp.getText());
}
});
addDeserializer(LocalDateTime.class, new JsonDeserializer<LocalDateTime>() {
#Override
public LocalDateTime deserialize(JsonParser jp, DeserializationContext ctxt) throws IOException, JsonProcessingException {
return LocalDateTime.parse(jp.getText());
}
});
}
}
Register this module in servlet-springs.xml
<bean id="objectMapper" class="org.codehaus.jackson.map.ObjectMapper"/>
<bean name="localDateModule" class="packge.LocalDateSimpleModule">
<constructor-arg name="name" value="LocalDateModule" />
<constructor-arg name="version" ref="version" />
</bean>
<bean name ="version" class="org.codehaus.jackson.Version">
<constructor-arg value="1"/>//some value
<constructor-arg value="1"/>
<constructor-arg value="1"/>
<constructor-arg value=" "/>

There is , missing in the mapping of the input properties. I also advice you to start using the console (key F12) to debug the code and discover problems easly.

It's a bit tricky to see exactly what'll be coming, but I think you could do:
var address_ac = new A.AutoCompleteList({... as you have it...});
address_ac.on('select', function (e) {
var selected_node = e.itemNode,
selected_data = e.result;
});
