Spring Security+jwt+redis+自定义认证逻辑 权限控制

1.拦截访问基本思路

在这里插入图片描述

2.创建数据库表：角色表（应该6个表，这里只用用户表代替角色表）、权限表、路径表、角色-权限表、权限-路径表

3.导入依赖

<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-security -->
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-security</artifactId><version>2.7.4</version>
</dependency>

###4.创建实现UserDestails的实现类

package com.rfos.assistsilkworm.config.security;import com.rfos.assistsilkworm.pojo.User;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;import java.util.ArrayList;
import java.util.Collection;
import java.util.List;/*** @author hjt* @date 2022/10/4 20:55* @description*/@Data
@AllArgsConstructor
@NoArgsConstructor
public class UserDetailsDTO implements UserDetails {private User user;private List<String> permissionList;private Collection<? extends GrantedAuthority> authorities;@Overridepublic Collection<? extends GrantedAuthority> getAuthorities() {List<GrantedAuthority> grantedAuthorityList = new ArrayList<>();for (String permission : permissionList) {//拥有的权限名SimpleGrantedAuthority simpleGrantedAuthority = new SimpleGrantedAuthority(permission);grantedAuthorityList.add(simpleGrantedAuthority);}setAuthorities(grantedAuthorityList);return grantedAuthorityList;}@Overridepublic String getPassword() {return user.getPassword();}@Overridepublic String getUsername() {return user.getUsername();}@Overridepublic boolean isAccountNonExpired() {return true;}@Overridepublic boolean isAccountNonLocked() {return true;}@Overridepublic boolean isCredentialsNonExpired() {return true;}@Overridepublic boolean isEnabled() {return true;}
}

UserDetails类：

UserDetails(位于org.springframework.security.core.userdetails包下)主要和用户信息有关的接口，该接口是提供用户信息的核心接口。该接口实现仅仅存储用户的信息。后续会将该接口提供的用户信息封装到认证对象Authentication中去

public interface UserDetails extends Serializable {// 权限// 用户的权限集， 默认需要添加ROLE_ 前缀Collection<? extends GrantedAuthority> getAuthorities();// 密码// 用户的加密后的密码， 不加密会使用{noop}前缀String getPassword();// 用户名String getUsername();// 帐户未过期boolean isAccountNonExpired();// 帐户未锁定boolean isAccountNonLocked();// 凭证是否过期boolean isCredentialsNonExpired();// 用户是否可用boolean isEnabled();
}

角色表等各个表对应的实体类

5.创建自定义认证逻辑-UserDetailsService的实现类-UserDetailServiceImpl类

UserDetailsService接口

package org.springframework.security.core.userdetails;
public interface UserDetailsService {UserDetails loadUserByUsername(String var1) throws UsernameNotFoundException;
}

UserDetailServiceImpl类

package com.rfos.assistsilkworm.config.security;import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.rfos.assistsilkworm.pojo.Permission;
import com.rfos.assistsilkworm.pojo.User;
import com.rfos.assistsilkworm.pojo.UserPermission;
import com.rfos.assistsilkworm.service.PermissionService;
import com.rfos.assistsilkworm.service.UserPermissionService;
import com.rfos.assistsilkworm.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;
import org.springframework.util.ObjectUtils;import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;/*** @author hjt* @date 2022/10/5 11:24* @description*/
@Service("userDetailsServiceImpl")
public class UserDetailsServiceImpl implements UserDetailsService {//用户业务@Autowiredprivate UserService userService;@Autowiredprivate PermissionService permissionService;@Autowiredprivate UserPermissionService userPermissionService;/*重写方法：username: 需要其数据的用户的用户名UsernameNotFoundException： 找不到用户的异常*/@Overridepublic UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {//获取用户并判断是否存在User user = userService.getByName(username);if(ObjectUtils.isEmpty(user)){return null;}//封装用户信息至对应的认证类中UserDetailsDTO userDetailsDTO = new UserDetailsDTO();userDetailsDTO.setUser(user);//TODO 获取角色对应的权限List<UserPermission> userPermissions = userPermissionService.list(new QueryWrapper<UserPermission>().eq("user_id", user.getUserId()));//TODO 获取权限id对应的所有权限List<String> pathList = new ArrayList<>();for (UserPermission userPermission : userPermissions) {List<Permission> permissionList = permissionService.list(new QueryWrapper<Permission>().eq("permission_id", userPermission.getPermissionId()));pathList.addAll(permissionList.stream().map(data-> data.getPermission()).collect(Collectors.toList()));}userDetailsDTO.setPermissionList(pathList);return userDetailsDTO;}}

6.JwtUtil工具类说明

/*** JWT工具类*/
public class JwtUtil {//有效期为public static final Long JWT_TTL = 60 * 60 * 1000L;// 60 * 60 *1000  一个小时//设置秘钥明文public static final String JWT_KEY = "sangeng";public static String getUUID() {//随机生成token字符串String token = UUID.randomUUID().toString().replaceAll("-", "");return token;}/*** 生成jtw** @param subject token中要存放的数据（json格式）* @return*/public static String createJWT(String subject) {JwtBuilder builder = getJwtBuilder(subject, null, getUUID());// 设置过期时间return builder.compact();}/*** 生成jtw** @param subject   token中要存放的数据（json格式）* @param ttlMillis token超时时间* @return*/public static String createJWT(String subject, Long ttlMillis) {JwtBuilder builder = getJwtBuilder(subject, ttlMillis, getUUID());// 设置过期时间return builder.compact();}private static JwtBuilder getJwtBuilder(String subject, Long ttlMillis, String uuid) {//签名的算法SignatureAlgorithm signatureAlgorithm = SignatureAlgorithm.HS256;//生成获取密钥SecretKey secretKey = generalKey();long nowMillis = System.currentTimeMillis();Date now = new Date(nowMillis);if (ttlMillis == null) {ttlMillis = JwtUtil.JWT_TTL;}long expMillis = nowMillis + ttlMillis;Date expDate = new Date(expMillis);return Jwts.builder().setId(uuid)              //唯一的ID.setSubject(subject)   // 主题  可以是JSON数据.setIssuer("sg")     // 签发者.setIssuedAt(now)      // 签发时间.signWith(signatureAlgorithm, secretKey) //使用HS256对称加密算法签名, 第二个参数为秘钥.setExpiration(expDate);//设置过期时间}/*** 创建token** @param id* @param subject* @param ttlMillis* @return*/public static String createJWT(String id, String subject, Long ttlMillis) {JwtBuilder builder = getJwtBuilder(subject, ttlMillis, id);// 设置过期时间return builder.compact();}/*** 生成加密后的秘钥 secretKey** @return*/public static SecretKey generalKey() {byte[] encodedKey = Base64.getDecoder().decode(JwtUtil.JWT_KEY);SecretKey key = new SecretKeySpec(encodedKey, 0, encodedKey.length, "AES");return key;}/*** 解析** @param jwt* @return* @throws Exception*/public static Claims parseJWT(String jwt) throws Exception {SecretKey secretKey = generalKey();return Jwts.parser().setSigningKey(secretKey).parseClaimsJws(jwt).getBody();}
}

7.，创建过滤器JwtAuthenticationTokenFilter类拦截指定路径验证访问信息

OncePerRequestFilter：继承OncePerRequestFilter用于继承实现并在每次请求时只执行一次过滤

package com.rfos.assistsilkworm.config.security;import com.alibaba.fastjson.JSONObject;
import com.rfos.assistsilkworm.config.redis.RedisUtils;
import com.rfos.assistsilkworm.config.security.UserDetailsDTO;
import com.rfos.assistsilkworm.constant.CommonConstants;
import com.rfos.assistsilkworm.enums.ResultCode;
import com.rfos.assistsilkworm.exception.ApiException;
import com.rfos.assistsilkworm.util.IPAddrUtil;
import com.rfos.assistsilkworm.util.JwtUtils;
import io.jsonwebtoken.Claims;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.stereotype.Component;
import org.springframework.util.StringUtils;
import org.springframework.web.filter.OncePerRequestFilter;import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.Objects;/*** @date 2022/10/4*/
@Slf4j
@Component
public class JwtAuthenticationTokenFilter extends OncePerRequestFilter {@Autowiredprivate RedisUtils redisUtil;//保证一次请求只调用一次doFilterInternal方法@Overrideprotected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {log.info("用户访问requestURI={},ip={}", request.getRequestURI(), IPAddrUtil.getIpAddress(request));//获取请求头中的tokenString token = request.getHeader(CommonConstants.TOKEN_HEAD);//如果没有token则为第一次访问，过滤器放行-将请求转发给过滤器链上下一个对象if (!StringUtils.hasText(token)) {filterChain.doFilter(request, response);return;}//解析tokenlog.info("获取到请求的token:\n"+token);String userId;try {Claims claims = JwtUtils.parseJWT(token);userId = claims.getSubject();} catch (Exception e) {e.printStackTrace();throw new ApiException(ResultCode.FAIL_AUTHORITY);}//从redis中获取用户信息Object obj = redisUtil.get(CommonConstants.TOKEN_HEAD + ":" + userId);if (Objects.isNull(obj)) {throw new ApiException(ResultCode.EMPTY_USER);}//获取认证对象的信息UserDetailsDTO userDetailsDTO = JSONObject.parseObject(obj.toString(), UserDetailsDTO.class);log.info("用户访问requestURI={},username={},ip={}", request.getRequestURI(), userDetailsDTO.getUsername(), IPAddrUtil.getIpAddress(request));//存入SecurityContextHolder//TODO 获取权限信息封装到Authentication中log.info("获取权限对应的所有权限:\n{}",userDetailsDTO.getAuthorities());/*UsernamePasswordAuthenticationToken继承AbstractAuthenticationToken实现Authentication所以当在页面中输入用户名和密码之后首先会进入到UsernamePasswordAuthenticationToken验证(Authentication)，然后生成的Authentication会被交由AuthenticationManager来进行管理而AuthenticationManager管理一系列的AuthenticationProvider，而每一个Provider都会通UserDetailsService和UserDetail来返回一个以UsernamePasswordAuthenticationToken实现的带用户名和密码以及权限的Authentication*/UsernamePasswordAuthenticationToken authenticationToken =new UsernamePasswordAuthenticationToken(userDetailsDTO, null, userDetailsDTO.getAuthorities());//将用户信息保存在安全上下文中SecurityContextHolder.getContext().setAuthentication(authenticationToken);//放行filterChain.doFilter(request, response);}}

8.创建自定义的UrlFilterInvocationSecurityMetadataSource类实现FilterInvocationSecurityMetadataSource接口

FilterInvocationSecurityMetadataSource：拦截url判断用户url的访问权限是否包含该用户的权限

package com.rfos.assistsilkworm.config.security;import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.rfos.assistsilkworm.pojo.Path;
import com.rfos.assistsilkworm.pojo.PermissionPath;
import com.rfos.assistsilkworm.service.PathService;
import com.rfos.assistsilkworm.service.PermissionPathService;

import java.util.Arrays;
import java.util.Collection;
import java.util.List;/*** @author hjt* @Package com.kdcloud.srd.security* @date 2022/10/5 20:14* @description 获取url匹配的用户权限**/
@Component
public class UrlFilterInvocationSecurityMetadataSource implements FilterInvocationSecurityMetadataSource {//没有权限private static final String ROLE_NONE = "ROLE_NONE";@Autowiredprivate PermissionPathService permissionPathService;@Autowiredprivate PermissionService permissionService;@Autowiredprivate PathService pathService;//路径匹配类AntPathMatcher antPathMatcher = new AntPathMatcher();//开放的路径private final static String[] OPEN_PATH_LIST = new String[]{"/**","/static/**","/templates/**","/index","/login","/admin/login","/home/**","/user/login","/swagger-ui.html","/swagger-resources/**","/*/api-docs","/webjars/**","/v2/**","/api/**","/actuator/**"};//filterInvocation：获取该请求@Overridepublic Collection<ConfigAttribute> getAttributes(Object requestObj) throws IllegalArgumentException {FilterInvocation filterInvocation = (FilterInvocation) requestObj;String requestUrl = filterInvocation.getRequestUrl();System.out.println("请求路径url："+requestUrl);//开放部分路径//静态资源不拦截if(isMatcherAllowedRequest(filterInvocation)){return null;}// 数据库中所有urlList<Path> pathList = pathService.list();pathList.forEach(value-> System.out.println(value.getPath()));for (Path path : pathList) {// 获取该url所对应的权限boolean match = antPathMatcher.match(path.getPath(), requestUrl);System.out.println(match);if (match) {System.out.println("匹配的路径url\n："+path);//获取路径对应的所有权限List<PermissionPath> permissionPaths = permissionPathService.list(new QueryWrapper<PermissionPath>().eq("path_id", path.getPathId()));List<String> permissionPathList = new ArrayList<>();if (!CollectionUtils.isEmpty(permissionPaths)){for (PermissionPath permissionPath : permissionPaths) {String roleName = permissionService.getById(permissionPath.getPermissionId()).getPermission();permissionPathList.add(roleName);}}// 能访问url对应角色权限信息System.out.println("能访问url对应角色权限信息:"+permissionPathList);return SecurityConfig.createList(permissionPathList.stream().toArray(String[]::new));}}// 如果数据中没有找到相应url资源则为非法访问return  SecurityConfig.createList(ROLE_NONE);}/*** 判断当前请求是否在允许请求的范围内* @param fi 当前请求* @return 是否在范围中*/private boolean isMatcherAllowedRequest(FilterInvocation fi){return allowedRequest().stream().map(AntPathRequestMatcher::new).filter(requestMatcher -> requestMatcher.matches(fi.getHttpRequest())).toArray().length > 0;}/*** @return 定义允许请求的列表*/private List<String> allowedRequest(){return Arrays.asList(OPEN_PATH_LIST);}@Overridepublic Collection<ConfigAttribute> getAllConfigAttributes() {return null;}/*** 表示返回的对象是否支持校验* @param aClass* @return*/@Overridepublic boolean supports(Class<?> aClass) {return FunctionalInterface.class.isAssignableFrom(aClass);}}

9.决策访问处理器：创建自定义的JwtAccessDeniedManager实现AccessDeniedManager接口

package com.rfos.assistsilkworm.config.security;import org.springframework.security.access.AccessDecisionManager;
import org.springframework.security.access.AccessDeniedException;
import org.springframework.security.access.ConfigAttribute;
import org.springframework.security.authentication.InsufficientAuthenticationException;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.stereotype.Component;import java.util.Collection;/*** @author hjt* @date 2022/10/5 23:29* @description决策访问处理器：创建自定义的JwtAccessDeniedManager实现AccessDeniedManager接口*/
@Component
public class JwtAccessDeniedManager implements AccessDecisionManager {/*** auth：认证信息* collection：角色信息*/@Overridepublic void decide(Authentication auth, Object o, Collection<ConfigAttribute> collection) throws AccessDeniedException, InsufficientAuthenticationException {Collection<? extends GrantedAuthority> auths = auth.getAuthorities();for (ConfigAttribute configAttribute : collection) {if ("ROLE_LOGIN".equals(configAttribute.getAttribute())&& auth instanceof UsernamePasswordAuthenticationToken) {return;}for (GrantedAuthority authority : auths) {if (configAttribute.getAttribute().equals(authority.getAuthority())) {return;}}}throw new AccessDeniedException("权限不足");}@Overridepublic boolean supports(ConfigAttribute configAttribute) {return true;}@Overridepublic boolean supports(Class<?> aClass) {return true;}
}

10.创建Spring Security的配置类securityConfig

package com.rfos.assistsilkworm.config.security;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;

import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.access.intercept.FilterSecurityInterceptor;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;import org.springframework.security.web.AuthenticationEntryPoint;
