结构不多说，bean的封装很简单，直接上核心代码吧，自己根据需要把不要的属性自己过滤掉：
public List<MenuBo> getMenuByUserId(Long user_id,Long company_id) { //获取所有的菜单 List<MenuBo> rootMenu = new ArrayList<>(); rootMenu = companyFuncInfoMapper.getMenuByUserId(user_id); List<Long> func_list = companyFuncInfoMapper.getFuncCompanyIdShipByCompanyId(company_id); Iterator<MenuBo> it=rootMenu.iterator(); while(it.hasNext()){ MenuBo menuBoIt=it.next(); if(!func_list.contains(menuBoIt.getId())){ it.remove(); } } //最后的结果 List<MenuBo> menuList = new ArrayList<>(); // 先找到所有的一级菜单 for (int i = 0; i < rootMenu .size(); i++) { // 一级菜单没有parentId if (rootMenu .get(i).getPid()==0L) { // 一级菜单没有parentId menuList.add(rootMenu.get(i)); } } // 为一级菜单设置子菜单，getChild是递归调用的 for (MenuBo menu : menuList) { Meta meta = new Meta(); meta.setBreadName(menu.getBreadName()); meta.setBreadIcon(menu.getBreadIcon()); meta.setTitle(menu.getBreadName()); menu.setComponent(menu.getComponent()); menu.setMeta(meta); menu.setChildren(getChild(menu.getId(), rootMenu)); } return menuList; }
获取子菜单的方法：
private static List<MenuBo> getChild(Long id, List<MenuBo> rootMenu) { // 子菜单 List<MenuBo> childList = new ArrayList<>(); for (MenuBo menu : rootMenu) { // 遍历所有节点，将父菜单id与传过来的id比较 if (menu.getPid()!=null) { if (menu.getPid().intValue()==id.intValue()) { Meta meta = new Meta(); meta.setBreadName(menu.getBreadName()); meta.setBreadIcon(menu.getBreadIcon()); meta.setTitle(menu.getBreadName()); menu.setMeta(meta); menu.setComponent(menu.getComponent()); menu.setTitle(menu.getBreadName()); childList.add(menu); } } } // 把子菜单的子菜单再循环一遍 for (MenuBo children : childList) {// 没有url子菜单还有子菜单 if (StringUtils.isBlank(children.getPath())) { // 递归 children.setChildren(getChild(children.getId(), rootMenu)); } } // 递归退出条件 if (childList.size() == 0) { return null; } return childList; }
最终结果：

大家看json结构自己写一下实体类就行了。
