Using JsonAnyGetter together with JsonInclude(Include.NON_EMPTY)

[gratzerl]

Hey, how does the JsonAnyGetter annotation deal with the following two scenarios:

• The Map<?, ?> field is empty
• The Map<?, ?> field is null

Do I have to add JsonInclude(Include.NON_EMPTY), or does JsonAnyGetter handle this already?

Thanks in advance :)

Hello, here is the behavior in question.

static class SimpleContainer {
        public String word = "word";

        protected Map<String, String> properties;

        @JsonAnyGetter
        public Map<String, String> getProperties() {
            return properties;
        }

        public void setProperties(Map<String, String> properties) {
            this.properties = properties;
        }
    }

    public void testSimpleContainer() throws Exception {
        SimpleContainer c = new SimpleContainer();
        c.setProperties(new HashMap<String, String>());
        assertEquals("{\"word\":\"word\"}", MAPPER.writeValueAsString(c));
    }

    public void testSimpleContainer2() throws Exception {
        SimpleContainer c = new SimpleContainer();
        c.setProperties(null);
        assertEquals("{\"word\":\"word\"}", MAPPER.writeValueAsString(c));
    }
