Hi, How is @JsonProperty supposed to work? Given the following documentation:
- @JsonProperty: Marker annotation that can be used to define a non-static method as a "setter" or "getter" for a logical property (depending on its signature), or non-static object field to be used (serialized, deserialized) as a logical property. - @JsonGetter: Marker annotation that can be used to define a non-static, no-argument value-returning (non-void) method to be used as a "getter" for a logical property, as an alternative to recommended JsonProperty <http://fasterxml.github.io/jackson-core/javadoc/1.9/org/codehaus/jackson/annotate/JsonProperty.html> annotation (which was introduced in version 1.1). Getter means that when serializing Object instance of class that has this method (possibly inherited from a super class), a call is made through the method, and return value will be serialized as value of the property. - @JsonSetter: Marker annotation that can be used to define a non-static, single-argument method to be used as a "setter" for a logical property as an alternative to recommended JsonProperty <http://fasterxml.github.io/jackson-annotations/javadoc/2.0.0/com/fasterxml/jackson/annotation/JsonProperty.html> annotation (which was introduced in version 1.1). Setter means that when a property with matching name is encountered in JSON content, this method will be used to set value of the property. I would expect that annotated getters take care of serialization, and setters of deserialization. But when using a class annotated with: @JsonIgnoreProperties(ignoreUnknown = true) @JsonAutoDetect(fieldVisibility = JsonAutoDetect.Visibility.NONE, getterVisibility = JsonAutoDetect.Visibility.NONE, setterVisibility = JsonAutoDetect.Visibility.NONE, isGetterVisibility = JsonAutoDetect.Visibility.NONE) *The following test:* ObjectMapper objectMapper = new ObjectMapper(); String string = objectMapper.writeValueAsString(new MyModelClass2( 1L, "Foo", "Bar", new Date(), "Baz", new Date(), "Bal", "Bo", "Bo" )); System.out.println(string); System.out.println(objectMapper.readValue("{\"createdBy\":\"Baz\",\"createdDate\":1475741455220," + "\"someNumber\":1,\"updatedBy\":\"Bar\",\"updatedDate\":1475741455220,\"someCondition\":\"Bo\"," + "\"firstName\":\"Bal\",\"someName\":\"Foo\"}", MyModelClass2.class)); *Has the following output:* //Serialization {"createdDate":1476431196458,"someNumber":1,"someCondition":"Bo","someName":"Foo"} //Deserialization MyModelClass2{createdBy='null', createdDate=Thu Oct 06 10:10:55 CEST 2016, someNumber=1, updatedBy='null', updatedDate=null, someCondition='Bo', firstName='null', someName='Foo'} The class MyModelClass2 only uses @JsonProperty on the getters, but clearly the properties are deserialized as well. What am I missing here? did I misinterpret the documentation? (I'm using Jackson 2.8.3) Kind Regards, Ewout. -- You received this message because you are subscribed to the Google Groups "jackson-user" group.
