Method that can be used to serialize any Java value as JSON output, using Writer provided.

Usage

From source file:net.hamnaberg.json.Template.java

public void writeTo(Writer writer) throws IOException {
    ObjectMapper factory = new ObjectMapper();
    ObjectNode template = JsonNodeFactory.instance.objectNode();
    template.set("template", asJson());
    factory.writeValue(writer, template);
}

From source file:nl.ortecfinance.opal.jacksonweb.IncomePlanningSimulationRequestTest.java

@Test
public void testSerializeDate() throws IOException {

    IncomePlanningSimulationRequest req = new IncomePlanningSimulationRequest();
    final Date today = DateUtils.createDate(2015, 4);
    final Date dobLieve = DateUtils.createDate(2008, 8, 24);
    req.setStartPeriod(today);//ww  w  .  j av a 2  s .  c  om
    req.setDob(dobLieve);
    req.setProcessingDate(today);

    System.out.println("today:" + today);
    System.out.println("Lieve:" + dobLieve);

    StringWriter sw = new StringWriter();
    ObjectMapper m = new ObjectMapper();
    m.writeValue(sw, req);

    String json = sw.toString();
    System.out.println("testSerializeDate:" + json);

    StringReader sr = new StringReader(json);
    m.enable(DeserializationFeature.FAIL_ON_NULL_FOR_PRIMITIVES);
    IncomePlanningSimulationRequest reqReadBack = m.readValue(sr, IncomePlanningSimulationRequest.class);

    Assert.assertEquals(dobLieve, reqReadBack.getDob());
    Assert.assertEquals(today, reqReadBack.getStartPeriod());
