JsonIgnoreProperties (jackson-annotations 2.3.4)

```
@Target(value={ANNOTATION_TYPE,TYPE,METHOD,CONSTRUCTOR,FIELD})
@Retention(value=RUNTIME)
public @interface JsonIgnoreProperties
```
Annotation that can be used to either suppress serialization of properties (during serialization), or ignore processing of JSON properties read (during deserialization).
Example:
```
 // to prevent specified fields from being serialized or deserialized
 // (i.e. not include in JSON output; or being set even if they were included)
 @JsonIgnoreProperties({ "internalId", "secretKey" })
 // To ignore any unknown properties in JSON input without exception:
 @JsonIgnoreProperties(ignoreUnknown=true)
```
Starting with 2.0, this annotation can be applied both to classes and to properties. If used for both, actual set will be union of all ignorals: that is, you can only add properties to ignore, not remove or override. So you can not remove properties to ignore using per-property annotation.

    Names of properties to ignore.
    
    Default:
    
    {}
  - ignoreUnknown
```
public abstract boolean ignoreUnknown
```
    Property that defines whether it is ok to just ignore any unrecognized properties during deserialization. If true, all properties that are unrecognized -- that is, there are no setters or creators that accept them -- are ignored without warnings (although handlers for unknown properties, if any, will still be called) without exception.
    Does not have any effect on serialization.
    
    Default:
    
    false
