springboot接口访问权限AOP实现

 

场景java

如今有个系统,不少接口只须要登陆就能够访问,可是有些接口须要授予并验证权限。若是用注解controller的方式控制接口的权限呢?数据库

 

一、注解声明代码json

这个注解是要装饰在controller接口上的。cookie

按照通常权限的设计,有用户(user)-角色(role)-权限(permission)三种实体,他们之间都是多对多关系。app

注解声明的时候,能够配置要验证的角色(role)或权限(menu)。因此我这里有两个变量。ide

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

/**
 * @Author: ivan
 * @Description:
 * @Date: Created in 19:58 18/5/28
 * @Modified By:
 */
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface Authentication {
    long[] role() default {};
    long[] menu() default {};

}

 

二、Authentication权限验证Adviceui

咱们以验证角色为例。spa

第一步,先从controller参数的request cookie里拿到用户登陆信息,获取userId,我这里是card。设计

第二步,查询用户角色数据库,获取该user拥有哪些权限。code

第三部,跟@Authentication里配置的权限进行比较,校验成功返回数据,校验失败返回错误码。

使用localthread记录了权限验证处理时间,用来进行监控。

/**

 * @Description:

@Aspect
@Component
@Order(-10)
public class AuthenticationAspect {

    private static Logger logger = LoggerFactory.getLogger(AuthenticationAspect.class);

    @Autowired
    private AuthDao authDao;

    ThreadLocal<Long> beginTime = new ThreadLocal<Long>();

    @Pointcut("@annotation(authentication)")
    public void AuthenticationService(Authentication authentication) {
    }

    @Around("AuthenticationService(authentication)")
    public Object doAround(ProceedingJoinPoint joinPoint, Authentication authentication) throws Throwable{
        beginTime.set(System.currentTimeMillis());
        String card = null;
        List<Long> roleList = new ArrayList<>();
        for (Object arg : joinPoint.getArgs()) {
            if (arg != null && arg.getClass() == RequestFacade.class) {
                RequestFacade request = (RequestFacade) arg;
                card = CookieUtils.getCardFromCookie(request);
                if (StringUtils.isEmpty(card)) {
                    return JsonResult.buildFailResult(-1, 1000, "权限验证未经过", null);
                }
                List<Role> roles = authDao.getRolesByCard(card);
                for (Role role : roles) {
                    roleList.add(role.getId());
                }
                break;
            }
        }
        logger.info("[authentication] user={}, roles={}", card, roleList);
        long[] aims = authentication.role();
        boolean isPass = false;
        for (long aim : aims) {
            if (roleList.contains(aim)) {
                isPass = true;
            }
        }
        if (isPass) {
            logger.info("[authentication] authentication pass, cost time: {}", System.currentTimeMillis() - beginTime.get());
            return joinPoint.proceed();
        } else {
            beginTime.set(System.currentTimeMillis());
            logger.info("[authentication] authentication reject, cost time: {}", System.currentTimeMillis() - beginTime.get());
            return JsonResult.buildFailResult(-1, 1000, "权限验证未经过", null);
        }

    }


}

 

三、使用方法

一、Authentication直接装饰在controller接口上,参数是role={2},即用户拥有2这个角色的时候拥有访问这个接口的权限。

二、controller第一个参数要是HttpServletRequest request,否则上面从request里面拿用户信息会失败。(这个地方确实不方便)

/**
 * 审核接口
 *
 * @author ivan
 * @date 2018/08/02
 */
@Controller
@RequestMapping("/audit")
public class AuditController {
    private static final Logger LOGGER = LoggerFactory.getLogger(AuditController.class);
    @Resource
    private AuditService auditService;

@ResponseBody @PostMapping(value = "/review") @Authentication(role = {2}) public JsonResult review(HttpServletRequest request, @RequestBody AduitDTO aduitDTO) { LOGGER.info("[aduitDTO] video service aduitDTO={}" + aduitDTO); UserInfo userInfo = CookieUtils.getLoginInfoFromCookie(request); aduitDTO.setCard(userInfo.getCard()); int status = 0; aduitDTO.setAuditor(userInfo.getCard()); JsonResult jsonResult = null; if (ListEnum.ZERO.toString().equals(aduitDTO.getType())) { if (null != aduitDTO.getStatus() && ListEnum.ONE.toString().equals(aduitDTO.getStatus())) { status = auditService.review(aduitDTO); jsonResult = JsonResult.buildSuccessResult("审核经过"); } if (null != aduitDTO.getStatus() && ListEnum.TWO.toString().equals(aduitDTO.getStatus())) { if(StringUtils.isEmpty(aduitDTO.getReason())){ return JsonResult.buildFailResult(1, 102, "请添加不经过缘由!", null); } aduitDTO.setAuditTime(DateUtils.parseDateToStr(new Date() ,"yyyy-MM-dd HH:mm:ss")); status = auditService.updateAduit(aduitDTO); jsonResult = JsonResult.buildSuccessResult("审核不经过"); } } return jsonResult; } }
