Customising Jersey JSON marshalling for java.util.Maps

问题

By default, marshalling a @XmlRootElement bean containing a map gives the structure:

myMap : {
    entry : {
        key : {
            ...
        },
        value : {
            ...
        }
    }
}

Is there any way to customise the JSON field names 'entry', 'key' and 'value'?

Use a custom @XmlJavaTypeAdapter. @Blaise Doughan has a clearly-written tutorial on using them.

See also XmlAdapter.
