  • 递归处理vue菜单数据

    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:
