JAVA将list转化为xml文件

pojo类：

 1 public class TreeNode {
 2     private int id;
 3     private String nodeId;
 4     private String parentId;
 5     private String hrefAddress;
 6     private String nodeName;
 7 
 8     public int getId() {
 9         return id;
10     }
11 
12     public void setId(int id) {
13         this.id = id;
14     }
15 
16     public String getNodeId() {
17         return nodeId;
18     }
19 
20     public void setNodeId(String nodeId) {
21         this.nodeId = nodeId;
22     }
23 
24     public String getParentId() {
25         return parentId;
26     }
27 
28     public void setParentId(String parentId) {
29         this.parentId = parentId;
30     }
31 
32     public String getHrefAddress() {
33         return hrefAddress;
34     }
35 
36     public void setHrefAddress(String hrefAddress) {
37         this.hrefAddress = hrefAddress;
38     }
39 
40     public String getNodeName() {
41         return nodeName;
42     }
43 
44     public void setNodeName(String nodeName) {
45         this.nodeName = nodeName;
46     }
47 
48 }

将list转化为xml形式的字符串的工具类：

 1 public class TreeUtil {
 2     /**
 3      * 根据节点数据集合，生成XML
 4      * @param treeNodes 权节点集合
 5      * @return
 6      */
 7     public String parseNodeToXML(List<TreeNode> treeNodes) {
 8         StringBuffer xmlnodes = new StringBuffer();
 9         if (treeNodes != null && treeNodes.size() > 0) {
10             xmlnodes.append("<?xml version="1.0" encoding="UTF-8"?>");
11             xmlnodes.append("<nodes>");
12             for (int i = 0; i < treeNodes.size(); i++) {
13                 TreeNode node = treeNodes.get(i);
14                 xmlnodes.append("<node nodeId='" + node.getNodeId() + "' parentId='" + node.getParentId()
15                         + "' hrefAddress='" + node.getHrefAddress() + "'>" + node.getNodeName() + "</node>");
16             }
17             xmlnodes.append("</nodes>");
18         }
19 
20         return xmlnodes.toString();
21     }
22 }

将字符串写入到文件中：

 1 public static void main(String[] args) throws Exception {
 2     List<TreeNode> list = new ArrayList<TreeNode>();
 3 
 4     for (int i = 0; i < 5; i++) {
 5         TreeNode treeNode = new TreeNode();
 6         treeNode.setHrefAddress("hrefAddress" + i);
 7         treeNode.setId(i);
 8         treeNode.setNodeId("nodeId" + i);
 9         treeNode.setNodeName("nodeName" + i);
10         treeNode.setParentId("parentId" + i);
11         list.add(treeNode);
12     }
13 
14     String xmlFile = new TreeUtil().parseNodeToXML(list);
15 
16     FileWriter writer = new FileWriter("F:/node.xml");
17 
18     writer.write(xmlFile);
19     writer.flush();
20     writer.close();
21     System.out.println("写入完成！");
22     }
