@JsonProperty annotation on field as well as getter/setter

I have inherited a certain bit code that has the @JsonProperty annotation on getter/setters. The purpose is so that when the object is serialized using the Jackson library, the fields have that specific name.

Current code:

private String fileName;

@JsonProperty("FILENAME")
public String getFileName()
{
    return fileName;
}

@JsonProperty("FILENAME")
public void setFileName(String fileName)
{
    this.fileName = fileName;
}

Now for another tool, I need to annotate the field with JsonProperty as well. So this will be my changed code:

@JsonProperty("FILENAME")
private String fileName;

@JsonProperty("FILENAME")
public String getFileName()
{
    return fileName;
}

@JsonProperty("FILENAME")
public void setFileName(String fileName)
{
    this.fileName = fileName;
}

Has anyone used this same annotation on both - the field as well as the getter/setters? I looked around on the net but didn't see anything.

I have compiled & run the code but I'm not sure if this would this cause any problems down the road. Any thoughts on this?
