insp4j轻量级权限框架

License License License

简介

  • insp4j为inspector的缩写,中文含义检查员。
  • 基于Spring-EL、AOP,更加灵活易用的权限控制框架,支持权限分组,可用于一套系统多种权限隔离校验,使用简单、易于扩展,支持Servlet、Reactive。
  • 参考了SpringSecurity、Expression的设计,定制扩展灵活。

需求背景

一个大的项目里会存在各种子业务系统,比如xx营销平台,提供给B端商户使用,其中包含的子业务系统有:
商城系统(多门店)、仓库系统(多仓库)、运营系统(多部门),系统交给不同的人员进行维护管理,这里统称操作员。
每个操作员能操作的功能,操作的门店/仓库/部门都是不一样的,甚至是不同的用户体系,不同的粗细粒度,
一般我们每个子业务系统会给不同的开发小组开发,如果没有设计统一的权限处理方案,各个小组会各自实现自己所负责的业务系统权限,很难管理。
insp4j就是抽象了一个group,把每个不同的子系统的权限设计区分隔离,不同的group,不同的用户、操作权限、数据权限,这些信息统一封装在InspAuthentication,需要业务系统来构造。
insp4j没有实现用户认证、授权,更没涉及到数据库层面上的数据范围过滤,只对业务系统构造的InspAuthentication、@Insp注解上定义的权限标识基于AOP实现拦截校验,是轻量级的权限控制实现。

快速开始

  • 导包
<!-- Servlet ->
<dependency>
    <groupId>cn.is4j.insp</groupId>
    <artifactId>insp4j-web</artifactId>
    <version>1.0.1</version>
</dependency>
<!-- Reactive ->
<dependency>
    <groupId>cn.is4j.insp</groupId>
    <artifactId>insp4j-reactive</artifactId>
    <version>1.0.1</version>
</dependency>
  • 配置
/**
 * 实现接口cn.is4j.insp.web.service.InspWebAuthenticationService返回认证用户的权限 并交由spring ioc管理
 */
@Component
public class InspWebAuthenticationServiceImpl implements InspWebAuthenticationService {

    @Autowired
    private DeptService deptService;
    @Autowired
    private MerchantService merchantService;

    /**
     * 建议走缓存 每次拦截都会进入该方法 这里只是演示
     */
    @Override
    public InspAuthentication loadAuthentication(HttpServletRequest httpServletRequest, String groupName) {
        // groupName可以用来做用户/权限隔离
        // 如系统用户在sys_user表,权限在sys_authorities表,一般用户(商户)在biz_merchant表,权限在biz_merchant_authorities表
        if("system".equals(groupName)){
            String userId = SecurityUtil.getUserId();
            List<String> funcAuthorities = SecurityUtil.getUser().getAuthorities();
            List<String> dataAuthorities = deptService.listDeptId();
            return new InspAuthentication(userId, funcAuthorities, dataAuthorities);
        }
        if("merchant".equals(groupName)){
            String userId = merchantService.getIdByToken(httpServletRequest.getHeader("token"));
            List<String> funcAuthorities = merchantService.listFuncAuthorities(userId);
            List<String> dataAuthorities = merchantService.listDataAuthorities(userId);
            return new InspAuthentication(userId, funcAuthorities, dataAuthorities);
        }
        throw new RuntimeException("error groupName");
    }
}
  • 使用
@RestController
@RequestMapping("/dept")
public class DeptController {

    //操作权限
    @Insp("hasFunc('dept:list')")
    @GetMapping("/list")
    public R<?> list() {
        return ok();
    }

    // 操作权限加数据权限 有没有操作该id的权限
    // 支持Spring-EL表达式
    @Insp(value = "hasFuncData('dept:update',#id)")
    @GetMapping("/updateById")
    public R<?> updateById(@RequestParam Long id) {
        return ok();
    }
    // 权限分组 业务系统/运营系统 可能用户账号体系不一样,权限体系也是分开设计的,就需要用到groupName来实现分组
    // 一个分组可以单独一套用户/权限
    @Insp(value = "hasFuncData('dept:delete',#id)", groupName = "system")
    @GetMapping("/deleteById")
    public R<?> deleteById(@RequestParam Long id) {
        return ok();
    }

}
  • 异常

    没有权限时默认异常,可定制

{"code":403,"message":"deny of access"}

计划

  • 系统与系统(微服务)之间的调用权限
  • 用户的认证与授权?OAuth?.待定
  • Spring-EL method IDE识别,点击跳转直接跳转到目标实现?.暂时还没研究出来(inject language or reference)不太理想

ps

这种基于AOP对注解上的权限标识做拦截是很简单的,相信大家都会,目前提供的功能比较简单,不喜勿喷
当下主要是解决我们项目里各种系统权限控制不统一,每个子系统不同小组在开发,各自做各自的,增加一个子系统就要做一套权限,没有统一模式。 代码比较简单,注释用的散装英文,主要是为了练习英文,不是装13哦,太散装了也装不起来。
