@JsonIgnoreProperties usage for both known and unknown properties

Question

My current annotation for ignoring the known properties for a JPA entity is:

@JsonIgnoreProperties({"hibernateLazyInitializer", "handler","created","updated","createdBy","lastUpdatedBy"}) 

In addition to ignoring these class properties, I would also like to ignore any unknown properties that the server receives. I know the alone way to ignore the unknown properties by the following annotation:

@JsonIgnoreProperties(ignoreUnknown=true) 

But not sure how to add this to my current annotation given above. I tried multiple methods ås below but none seem to work and I could not find an example online for this scenario.

Any example or leads on documentation would also help.

Answer 1

Set ignoreUnknown to true and define the names of properties to ignore in the value element:

@JsonIgnoreProperties(ignoreUnknown = true,                        value = {"hibernateLazyInitializer", "handler", "created"}) 

How does it work?

Have a look at this quote from the documentation (highlight is mine):

In its simplest form, an annotation looks like the following:

@Entity 

The at sign character (@) indicates to the compiler that what follows is an annotation. In the following example, the annotation's name is Override:

@Override void mySuperMethod() { ... } 

The annotation can include elements, which can be named or unnamed, and there are values for those elements:

@Author(name = "Benjamin Franklin", date = "3/27/2003") class MyClass() { ... } 

or

@SuppressWarnings(value = "unchecked") void myMethod() { ... } 

If there is just one element named value, then the name can be omitted, as in:

@SuppressWarnings("unchecked") void myMethod() { ... } 

Other way to handle unknown properties

To ignore unknown properties, you also could do:

ObjectMapper mapper = new ObjectMapper(); mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
