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)
```
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.

java.lang.String[] value
```
    Names of properties to ignore.
    
    Default:
    
    {}
- - ignoreUnknown
```
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.
    
    Returns:
    
    True if any and all unknown properties are to be ignored without exceptions (or other special handling); false otherwise.
    
    Default:
    
    false
- - allowGetters
```
boolean allowGetters
```
    Property that can be enabled to allow "getters" to be used (that is, prevent ignoral of getters for properties listed in value()). This is commonly set to support defining "read-only" properties; ones for which there is a getter, but no matching setter: in this case, properties should be ignored for deserialization but NOT serialization. Another way to think about this setting is that setting it to `true` will "disable" ignoring of getters.
    Default value is `false`, which means that getters with matching names will be ignored.
    
    Returns:
    
    True if getters should be allowed (i.e. NOT ignored); false if getters are to be ignored
    
    Since:
    
    2.6
    
    Default:
    
    false
- - allowSetters
```
boolean allowSetters
```
    Property that can be enabled to allow "setters" to be used (that is, prevent ignoral of setters for properties listed in value()). This could be used to specify "write-only" properties; ones that should not be serialized out, but that may be provided in for deserialization. Another way to think about this setting is that setting it to `true` will "disable" ignoring of setters.
    Default value is `false`, which means that setters with matching names will be ignored.
    
    Returns:
    
    True if setters should be allowed (i.e. NOT ignored); false if setters are to be ignored
    
    Since:
    
    2.6
    
    Default:
    
    false
