Description
I encountered a situation where a property annotated with both `@JsonProperty` and `@JsonIgnore` is not being serialized. In [Jackson wiki](https://github.com/FasterXML/jackson-annotations/wiki/Jackson-Annotations) said, that `@JsonProperty`:
> also indicates that property is to be included
Based on this, I assumed that `@JsonProperty` would override `@JsonIgnore`. However, in the following example, the property is omitted from the serialized JSON:
```java
public class Box {
@JsonProperty
@JsonIgnore
private int size;
public Box(int size) {
this.size = size;
}
public static void main(String[] args) throws JsonProcessingException {
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.disable(SerializationFeature.FAIL_ON_EMPTY_BEANS);
Box box = new Box(10);
String json = objectMapper.writeValueAsString(box);
System.out.println(json);
}
}
```
Expected output:
```json
{"size":10}
```
But got:
```json
{}
```
**Jackson version**: `2.19.3`
I used a very simple example just to demonstrate the behavior, but the same issue also occurs with subclasses.
If this behavior is expected, it would be very helpful to have documentation describing the priority of different annotations, because it is currently unclear which annotation takes precedence over others.
