Java 我可以将单个xml属性解组为多元素数组吗？

给定以下xml代码：

<root>
  <vector>{1, 2, 3, 4, 5}</vector>
</root>

在我尝试这样做的过程中，我编写了一些代码，但它无法将

正确地拆分为一个数组，其中每个数字都是一个单独的元素：

@XmlType(propOrder = {"vector"})
@XmlRootElement(name = "root")
public class Data
{
  // class data
  private int[] vector;

  @XmlElement(name = "vector")
  public void setVector(int[] vector)
  {
    this.vector = vector;
  }

  public int[] getVector()
  {
    return vector;
  }
}

您需要一个XmlAdapter，如下所示：

public class VectorAdapter extends XmlAdapter<String, int[]> {

    @Override
    public int[] unmarshal(final String v) throws Exception {
        final String[] strs = v.substring(1, v.length() - 1).split(",");
        final int[] vector = new int[strs.length];
        for (int i = 0; i < strs.length; i++) {
            vector[i] = Integer.parseInt(strs[i].trim());
        }
        return vector;
    }

    @Override
    public String marshal(final int[] v) throws Exception {
        return null;
    }
}

谢谢，这正是我想要的：）

public class VectorAdapter extends XmlAdapter<String, int[]> {

    @Override
    public int[] unmarshal(final String v) throws Exception {
        final String[] strs = v.substring(1, v.length() - 1).split(",");
        final int[] vector = new int[strs.length];
        for (int i = 0; i < strs.length; i++) {
            vector[i] = Integer.parseInt(strs[i].trim());
        }
        return vector;
    }

    @Override
    public String marshal(final int[] v) throws Exception {
        return null;
    }
}

@XmlJavaTypeAdapter(VectorAdapter.class)
@XmlElement(name = "vector")
public void setVector(final int[] vector) {
    this.vector = vector;
}
