引入依赖
org.springframework.boot spring-boot-starter-aop
定义注解
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(); }
拦截实现登录和权限验证
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 com.lmxdawn.api.admin.service.auth.AuthLoginService; import com.lmxdawn.api.common.utils.JwtUtils; import io.jsonwebtoken.Claims; import lombok.extern.slf4j.Slf4j; import org.aspectj.lang.JoinPoint; import org.aspectj.lang.annotation.Aspect; import org.aspectj.lang.annotation.Before; import org.aspectj.lang.annotation.Pointcut; import org.aspectj.lang.reflect.MethodSignature; import org.springframework.stereotype.Component; import org.springframework.web.context.request.RequestContextHolder; import org.springframework.web.context.request.ServletRequestAttributes; import javax.annotation.Resource; 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) { ListauthRules = 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); } } }
Controller 中使用
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) { ListauthRoleAdmins = 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); }
