Java-Jackson 序列化 ArrayList<string> 到具有不同子名的 XML</string>

Question

I've been using jackson-dataformatter-v2.9.10 to serialize a Java class into an XML string.

This is my class:

public class parent()
{
    public ArrayList<String> children;

    public parent() {
       
         children = new ArrayList<String>();
    }
}

Here is what I want to achieve:

<parent>
    <children>
      <child>John</child>
      <child>Ben</child>
      <child>Mary</child>
    </children>
</parent>

Here is what I'm getting:

<parent>
    <children>
      <children>John</children>
      <children>Ben</children>
      <children>Mary</children>
    </children>
</parent>

Any suggestion on how to change the ArrayList children element names ?

Answer 1

Use both @JacksonXmlElementWrapper and @JacksonXmlProperty on the list field.

Here is some sample code:

    @JacksonXmlElementWrapper(localName = "children")
    @JacksonXmlProperty(localName = "child")
    private List<String> child = new LinkedList<>();

The ElementWrapper is for the outer element (the one that contains the repeating elements). The XmlProperty is for the inner element (the one that repeats).

Answer 2

You should be able to use

@JacksonXmlElementWrapper(localName = "children")
List<String> child;
