JAVA将list转化为xml文件

pojo类：

public class TreeNode {
	private int id;
	private String nodeId;
	private String parentId;
	private String hrefAddress;
	private String nodeName;

	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}

	public String getNodeId() {
		return nodeId;
	}

	public void setNodeId(String nodeId) {
		this.nodeId = nodeId;
	}

	public String getParentId() {
		return parentId;
	}

	public void setParentId(String parentId) {
		this.parentId = parentId;
	}

	public String getHrefAddress() {
		return hrefAddress;
	}

	public void setHrefAddress(String hrefAddress) {
		this.hrefAddress = hrefAddress;
	}

	public String getNodeName() {
		return nodeName;
	}

	public void setNodeName(String nodeName) {
		this.nodeName = nodeName;
	}

}

将list转化为xml形式的字符串的工具类：

public class TreeUtil {
	/**
	 * 根据节点数据集合，生成XML
	 * @param treeNodes 权节点集合
	 * @return
	 */
	public String parseNodeToXML(List<TreeNode> treeNodes) {
		StringBuffer xmlnodes = new StringBuffer();
		if (treeNodes != null && treeNodes.size() > 0) {
			xmlnodes.append("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
			xmlnodes.append("<nodes>");
			for (int i = 0; i < treeNodes.size(); i++) {
				TreeNode node = treeNodes.get(i);
				xmlnodes.append("<node nodeId='" + node.getNodeId() + "' parentId='" + node.getParentId()
						+ "' hrefAddress='" + node.getHrefAddress() + "'>" + node.getNodeName() + "</node>");
			}
			xmlnodes.append("</nodes>");
		}

		return xmlnodes.toString();
	}
}

将字符串写入到文件中：

public static void main(String[] args) throws Exception {
	List<TreeNode> list = new ArrayList<TreeNode>();

	for (int i = 0; i < 5; i++) {
	    TreeNode treeNode = new TreeNode();
	    treeNode.setHrefAddress("hrefAddress" + i);
	    treeNode.setId(i);
	    treeNode.setNodeId("nodeId" + i);
	    treeNode.setNodeName("nodeName" + i);
	    treeNode.setParentId("parentId" + i);
	    list.add(treeNode);
	}

	String xmlFile = new TreeUtil().parseNodeToXML(list);

	FileWriter writer = new FileWriter("F:/node.xml");

	writer.write(xmlFile);
	writer.flush();
	writer.close();
	System.out.println("写入完成！");
    }
