Ignoring null values when marshaling an object to JSON with RESTeasy and Jettison

Question

When RESTeasy marshals a POJO into XML, it will skip null values by default: See Jaxb marshaller always writes xsi:nil (even when @XmlElement(required=false, nillable=true)).

However, when marshaling to JSON, null properties are included. Is there any way to force the JSON output to match the XML output?

Answer 1

To ensure that null values are not included in the JSON, the following annotation can be applied on the getter or public variable declaration: @JsonSerialize(include = Inclusion.NON_NULL)
