使用递归的方式删除菜单

//递归删除菜单
@Override
public void removeChildByIdGuli(String id) {
    //创建list集合，用于封装所有删除菜单的id值
    List<String> idList = new ArrayList<>();
    //向idList集合设置删除菜单id
    this.selectPermissionChildById(id,idList);
    //把当前id封装到id里面
    idList.add(id);
    baseMapper.deleteBatchIds(idList);
}
//根据当前菜单id，查询菜单里面子菜单id，封装到list集合中
private void selectPermissionChildById(String id,List<String> idList) {
    //查询菜单里的子id
    QueryWrapper<Permission> wrapper = new QueryWrapper<>();
    wrapper.eq("pid",id);
    wrapper.select("id");
    List<Permission> childIdList = baseMapper.selectList(wrapper);
    //childIdList里面菜单id值获取出来，封装到idList里面，并且要做递归的操作
    childIdList.stream().forEach(item -> {
         //封装idList里面去
        idList.add(item.getId());
        //递归查询
        this.selectPermissionChildById(item.getId(), idList);
    });
}

//给角色分配菜单（权限）
    @Override
    public void saveRolePermissionRealtionShipGuli(String roleId, String[] permissionId) {
        //创建一个list集合用于最后封装添加数据
        List<RolePermission> rolePermissionList = new ArrayList<>();
        //遍历所有的菜单数组
        for (String perId : permissionId) {
            RolePermission rolePermission = new RolePermission();
            rolePermission.setRoleId(roleId);
            rolePermission.setPermissionId(perId);
            //封装到list集合
            rolePermissionList.add(rolePermission);
        }
        //添加到角色菜单关系表
        rolePermissionService.saveBatch(rolePermissionList);
    }
