Write-only properties with Jackson

Question

In my entity class, I\'m trying to make a write-only field (gets ignored during serialization, but gets de-serialized normally).

@JsonProperty
@JsonSerialize         


        

Answer 1

You can set access value:

@JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
private String password;

Answer 2

Use @JsonIgnore on just the getter getPassword, instead of using the NullSerializer. Then also use @JsonProperty("password") on the setter.

This should allow password to be de-serialized, but the JSON output of serialization won't include it.

For example, a "getter" method that would otherwise denote a property (like, say, "getValue" to suggest property "value") to serialize, would be ignored and no such property would be output unless another annotation defines alternative method to use.
