WildFly 8.1.0 uses Jackson 2.3.2 so we can add the following dependencies to the pom with a scope of provided:
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.4.2</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>2.4.2</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.4.2</version>
<scope>provided</scope>
</dependency>
Then on the LocalDate property of your bean add the following annotations:public class MyBean {
@JsonDeserialize(using = JsonDateDeserializer.class)
@JsonSerialize(using = JsonDateSerializer.class)
private LocalDate date;
public LocalDate getDate() {
return date;
}
private void setDate(LocalDate date) {
this.date = date;
}
}
Now create the custom JsonDateSerializer:public class JsonDateSerializer extends JsonSerializer<LocalDate> {
private final DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd");
@Override
public void serialize(LocalDate date, JsonGenerator generator,
SerializerProvider provider) throws IOException,
JsonProcessingException {
String dateString = date.format(formatter);
generator.writeString(dateString);
}
}
And now the custom JsonDateDeserializer:public class JsonDateDeserializer extends JsonDeserializer<LocalDate> {
@Override
public LocalDate deserialize(JsonParser jp, DeserializationContext ctxt)
throws IOException, JsonProcessingException {
ObjectCodec oc = jp.getCodec();
TextNode node = (TextNode) oc.readTree(jp);
String dateString = node.textValue();
Instant instant = Instant.parse(dateString);
LocalDateTime dateTime = LocalDateTime.ofInstant(instant, ZoneId.systemDefault());
LocalDate date = LocalDate.of(dateTime.getYear(), dateTime.getMonth(), dateTime.getDayOfMonth());
return date;
}
}
NOTE: The package names have changed in Jackson 2. When you use the Jackson annotations make sure you import the one from the com.fasterxml.jackson.databind.annotation.* package and not the ones from the org.codehaus.jackson.map.annotate.* package. If you import the latter, your annotations will be ignored. WildFly 8 does not load the classes from the 1.9.2 jackson module.
