{demo=[ServiceInstance(appSymbol:demo,appIp:127.0.0.1),ServiceInstance(appSymbol:demo,appIp:127.0.0.2)]}转换成树结构Java代码

以下是将{demo=[ServiceInstance(appSymbol:demo,appIp:127.0.0.1),ServiceInstance(appSymbol:demo,appIp:127.0.0.2)]}转换成树结构的Java代码：

import java.util.*;

class Node {
    String name;
    List<Node> children;

    public Node(String name) {
        this.name = name;
        children = new ArrayList<>();
    }
}

public class Main {
    public static void main(String[] args) {
        Map<String, List<String>> map = new HashMap<>();
        map.put("demo", Arrays.asList("ServiceInstance(appSymbol:demo,appIp:127.0.0.1)", "ServiceInstance(appSymbol:demo,appIp:127.0.0.2)"));

        Node root = new Node("root");
        for (Map.Entry<String, List<String>> entry : map.entrySet()) {
            String key = entry.getKey();
            List<String> values = entry.getValue();
            Node node = new Node(key);
            for (String value : values) {
                Node child = new Node(value);
                node.children.add(child);
            }
            root.children.add(node);
        }

        printTree(root, 0);
    }

    private static void printTree(Node node, int depth) {
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < depth; i++) {
            sb.append("-");
        }
        sb.append(node.name);
        System.out.println(sb.toString());
        for (Node child : node.children) {
            printTree(child, depth + 1);
        }
    }
}

输出结果：

-root
--demo
---ServiceInstance(appSymbol:demo,appIp:127.0.0.1)
---ServiceInstance(appSymbol:demo,appIp:127.0.0.2)
