spring boot 利用注解实现权限验证

摘要：这里使用来实现权限验证引入依赖定义注解后台登录授权权限验证的注解此注解只能修饰方法当前注解如何去保持拦截实现登录和权限验证登录验证登录验证验证判断是否进行权限验证从切面中获取当前方法得到了方提取出他的注解进行权限验证权限验证为最高

这里使用 aop 来实现权限验证

    org.springframework.boot
    spring-boot-starter-aop

package com.lmxdawn.api.admin.annotation;

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

/**
 * 后台登录授权/权限验证的注解
 */
//此注解只能修饰方法
@Target(ElementType.METHOD)
//当前注解如何去保持
@Retention(RetentionPolicy.RUNTIME)
public @interface AuthRuleAnnotation {
    String value();
}

package com.lmxdawn.api.admin.aspect;

import com.lmxdawn.api.admin.annotation.AuthRuleAnnotation;
import com.lmxdawn.api.admin.enums.ResultEnum;
import com.lmxdawn.api.admin.exception.JsonException;

import io.jsonwebtoken.Claims;
import lombok.extern.slf4j.Slf4j;
import org.aspectj.lang.JoinPoint;

import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;
import java.lang.reflect.Method;
import java.util.List;

/**
 * 登录验证 AOP
 */
@Aspect
@Component
@Slf4j
public class AuthorizeAspect {

    @Resource
    private AuthLoginService authLoginService;

    @Pointcut("@annotation(com.lmxdawn.api.admin.annotation.AuthRuleAnnotation)")
    public void adminLoginVerify() {
    }

    /**
     * 登录验证
     *
     * @param joinPoint
     */
    @Before("adminLoginVerify()")
    public void doAdminAuthVerify(JoinPoint joinPoint) {

        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        if (attributes == null) {
            throw new JsonException(ResultEnum.NOT_NETWORK);
        }
        HttpServletRequest request = attributes.getRequest();

        String id = request.getHeader("X-Adminid");

        Long adminId = Long.valueOf(id);

        String token = request.getHeader("X-Token");
        if (token == null) {
            throw new JsonException(ResultEnum.LOGIN_VERIFY_FALL);
        }

        // 验证 token
        Claims claims = JwtUtils.parse(token);
        if (claims == null) {
            throw new JsonException(ResultEnum.LOGIN_VERIFY_FALL);
        }
        Long jwtAdminId = Long.valueOf(claims.get("admin_id").toString());
        if (adminId.compareTo(jwtAdminId) != 0) {
            throw new JsonException(ResultEnum.LOGIN_VERIFY_FALL);
        }

        // 判断是否进行权限验证
        MethodSignature signature = (MethodSignature) joinPoint.getSignature();
        //从切面中获取当前方法
        Method method = signature.getMethod();
        //得到了方,提取出他的注解
        AuthRuleAnnotation action = method.getAnnotation(AuthRuleAnnotation.class);
        // 进行权限验证
        authRuleVerify(action.value(), adminId);
    }

    /**
     * 权限验证
     *
     * @param authRule
     */
    private void authRuleVerify(String authRule, Long adminId) {

        if (authRule != null && authRule.length() > 0) {

            List authRules = authLoginService.listRuleByAdminId(adminId);
            // admin 为最高权限
            for (String item : authRules) {
                if (item.equals("admin") || item.equals(authRule)) {
                    return;
                }
            }
            throw new JsonException(ResultEnum.AUTH_FAILED);
        }

    }

}

使用 AuthRuleAnnotation 注解, value 值就是在数据库里面定义的 权限规则名称

/**
 * 获取管理员列表
 */
@AuthRuleAnnotation("admin/auth/admin/index")
@GetMapping("/admin/auth/admin/index")
public ResultVO index(@Valid AuthAdminQueryForm authAdminQueryForm,
                      BindingResult bindingResult) {

    if (bindingResult.hasErrors()) {
        return ResultVOUtils.error(ResultEnum.PARAM_VERIFY_FALL, bindingResult.getFieldError().getDefaultMessage());
    }

    if (authAdminQueryForm.getRoleId() != null) {
        List authRoleAdmins = authRoleAdminService.listByRoleId(authAdminQueryForm.getRoleId());
        List ids = new ArrayList<>();
        if (authRoleAdmins != null && !authRoleAdmins.isEmpty()) {
            ids = authRoleAdmins.stream().map(AuthRoleAdmin::getAdminId).collect(Collectors.toList());
        }
        authAdminQueryForm.setIds(ids);
    }
    List authAdminList = authAdminService.listAdminPage(authAdminQueryForm);

    // 查询所有的权限
    List adminIds = authAdminList.stream().map(AuthAdmin::getId).collect(Collectors.toList());
    List authRoleAdminList = authRoleAdminService.listByAdminIdIn(adminIds);

    // 视图列表
    List authAdminVoList = authAdminList.stream().map(item -> {
        AuthAdminVo authAdminVo = new AuthAdminVo();
        BeanUtils.copyProperties(item, authAdminVo);
        List roles = authRoleAdminList.stream()
                .filter(authRoleAdmin -> authAdminVo.getId().equals(authRoleAdmin.getAdminId()))
                .map(AuthRoleAdmin::getRoleId)
                .collect(Collectors.toList());
        authAdminVo.setRoles(roles);
        return authAdminVo;
    }).collect(Collectors.toList());

    PageInfo authAdminPageInfo = new PageInfo<>(authAdminList);
    PageSimpleVO authAdminPageSimpleVO = new PageSimpleVO<>();
    authAdminPageSimpleVO.setTotal(authAdminPageInfo.getTotal());
    authAdminPageSimpleVO.setList(authAdminVoList);

    return ResultVOUtils.success(authAdminPageSimpleVO);
