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！");
     }
