自己一个个循环判断虽然可以实现，但是工程量比较大，而且要是增加层次，就又得自己手动添加。。如果用递归的话。返回的类型不知道怎么去控制。求大佬抬一手。应该怎样返回合适的类型。达成map的嵌套存储

大佬代码如下：

import java.util.List;
    import com.alibaba.fastjson.JSON;
    import com.alibaba.fastjson.TypeReference;
    
    class Bean {
    	private Integer id;
    	private String title;
    	private List<Bean> children;
    	@Override
    	public String toString() {
    		return "Bean [id=" + id + ", title=" + title + ", children=" + children + "]";
    	}
    	public Integer getId() {
    		return id;
    	}
    	public void setId(Integer id) {
    		this.id = id;
    	}
    	public String getTitle() {
    		return title;
    	}
    	public void setTitle(String title) {
    		this.title = title;
    	}
    	public List<Bean> getChildren() {
    		return children;
    	}
    	public void setChildren(List<Bean> children) {
    		this.children = children;
    	}
    }
    
    public class MainTest {
    	public static void main(String[] args) {
    
    		String json = "[{\"id\":22,\"title\":\"游客\",\"children\":[{\"id\":31,\"title\":\"8\",\"children\":[{\"id\":41,\"title\":\"18\"}]}]},{\"id\":33,\"title\":\"科皓\",\"children\":[{\"id\":34,\"title\":\"10\",\"children\":[{\"id\":42,\"title\":\"18\"},{\"id\":84,\"title\":\"15\"}]}]}]";
    		
    		List<Bean> result = JSON.parseObject(json, new TypeReference<List<Bean>> () {});
    		
    		System.out.println(JSON.toJSONString(result));
    	}
    }
