1.先放一张最终结果图片,如果你认为这主是你要的结果,那请把接着往下看代码
2.代码为封装成了一个工具类,有需要的小伙伴直接control+c吧
package com.sunkee.business.admin.common.utils;
import com.sunkee.business.admin.common.domain.XTreeGrid;
import com.sunkee.business.admin.common.model.ShiroPermissions;
import com.sunkee.business.make.utils.StringUtil;
import net.sf.json.JSONArray;
import java.util.ArrayList;
import java.util.List;

*/
public class XTreeKit {
public static List<XTreeGrid> formatTree(List<ShiroPermissions> permissions) {
List<XTreeGrid> menuList = new ArrayList<XTreeGrid>();
for (ShiroPermissions ps:permissions) {
if(ps.getPermParentCode().equals("0")){ //遍历所有一级节点,并找出所有一级节点下的所有子节点

}
}

}

*/

// 遍历所有节点,将父菜单编码与传过来的编码进行比较、若相同则继续查看该节点下是否还有子节点
if (!StringUtil.isEmpty(root.getPermParentCode())) {
if (root.getPermParentCode().equals(id)) {
XTreeGrid grid = getXTreeGrid(root, rootMenu);
childList.add(grid);
}

//构建 XTreeGrid(实体对象)

XTreeGrid x = new XTreeGrid();
x.setId(ps.getPermId());
x.setCode(ps.getPermCode());

x.setTitle(ps.getPermName());
x.setValue(ps.getPermPermission());
x.setData(getChild(ps.getPermCode(),permissions)); //递增遍历所有子节点(无限层级)
return x;
}
}
3.直接调用

List<XTreeGrid> grid = XTreeKit.formatTree(permissions);

}
