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！");
    }
