How to set default properties to ignore for json serialization

[Alexander]

Instead of annotating many classes with this annotation, i would like to set the ignoreproperties globally by default for atleast the properties with these names:

@JsonIgnoreProperties({
        "JavassistLazyInitializer",
        "hibernateLazyInitializer",
        "handler"})

Pointing me how this can be done will be greatly appreciated

How can i set default properties to ignore for json serialization

There is no mechanism to ignore specifically named properties from every class to serialize, but there are some alternatives to using `@JsonIgnoreProperties` on a class:

1. Config overrides: you can apply equivalent of annotation on specific classes:

   mapper.configOverride(Point.class)

            .setIgnorals(JsonIgnoreProperties.Value.forIgnoredProperties("x", "y", "z"));

2. If you want to ignore all properties with specific type of value, either

    @JsonIgnoreType on class (possibly via mix-in annotations)

     or another config override

   mapper.configOverride(AnotherType.class)

      .setIsIgnoredType(true);

3. You can "fake" finding `@JsonIgnoreProperties` on every type, to effectively get what you

   want by sub-classing `JacksonAnnotationIntrospector` method

    public JsonIgnoreProperties.Value findPropertyIgnorals(Annotated ac) {

        if (ac instanceof AnnotatedClass) { // may also check it's for specific class(es)

           return JsonIgnoreProperties.Value.forIgnoredProperties("x", "y", "z");

        }

        return JsonIgnoreProperties.Value.empty();

    }

Last method is probably what you want to use here.

Hope this helps!
