Can JAXB output an ArrayList as comma separated values?

Question

I have something like

@XmlElementWrapper(name=\"Mylist\")
List myItems = new ArrayList()

and that comes out lik

Answer 1

you can accomplish that by making the field transient @XmlTransient and creating a method for calculating a String with a comma-separated.

@XmlTransient
List myItems = new ArrayList()

@XmlElement(name = "myItems")
public String getItemsAsCommasSeparated() {
    return String.join(", ", myItems);
}

About the wrapping if it is really necessary you will have to wrap the list into a another object.
