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>

###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;

    @Override
    public 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;
    }

    @Override
    public String getPassword() {
        return user.getPassword();
    }

    @Override
    public String getUsername() {
        return user.getUsername();
    }

    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    @Override
    public boolean isAccountNonLocked() {
        return true;
    }


    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }

    @Override
    public 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

 */
@Service("userDetailsServiceImpl")
public class UserDetailsServiceImpl implements UserDetailsService {
    //用户业务
    @Autowired
    private UserService userService;
    @Autowired
    private PermissionService permissionService;
    @Autowired
    private 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
    */
    @Override
    public 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

/**

 */
public class JwtUtil {

    //有效期为
    public static final Long JWT_TTL = 60 * 60 * 1000L;// 60 * 60 *1000  一个小时

    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

                .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;

    //保证一次请求只调用一次doFilterInternal方法
    @Override

        log.info("用户访问requestURI={},ip={}", request.getRequestURI(), IPAddrUtil.getIpAddress(request));
        //获取请求头中的token
        String 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token
        log.info("获取到请求的token:\n"+token);
        String userId;
        try {
            Claims claims = JwtUtils.parseJWT(token);
            userId = claims.getSubject();

        //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 org.springframework.stereotype.Component;
import org.springframework.util.AntPathMatcher;
import org.springframework.util.CollectionUtils;
import org.springframework.security.access.SecurityConfig;

import java.util.ArrayList;

        }
        // 数据库中所有url
        List<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);

                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));

    private boolean isMatcherAllowedRequest(FilterInvocation fi){
        return allowedRequest().stream().map(AntPathRequestMatcher::new)
                .filter(requestMatcher -> requestMatcher.matches(fi.getHttpRequest()))

     */
    @Override
    public 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
     */
    @Override
    public 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");
    }

    @Override
    public boolean supports(ConfigAttribute configAttribute) {
        return true;
    }

    @Override
    public 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.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;
import org.springframework.security.web.access.AccessDeniedHandler;


@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true) //开启注解匹配
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {
    //自动装配自定义逻辑
    @Autowired
    @Qualifier("userDetailsServiceImpl")
    private UserDetailsService userDetailsService;
    //过滤器JwtAuthenticationTokenFilter
    @Autowired
    private JwtAuthenticationTokenFilter jwtAuthenticationTokenFilter;
    //用户请求处理过程中遇到认证异常时，被ExceptionTranslationFilter用于开启特定认证方案(authentication schema)的认证流程
    @Autowired

    //拒绝访问处理
    @Autowired
    private AccessDeniedHandler accessDeniedHandler;
    //决策处理器
    @Autowired
    private JwtAccessDeniedManager jwtAccessDeniedManager;
    //请求访问url处理过滤器
    @Autowired
    private UrlFilterInvocationSecurityMetadataSource urlFilterInvocationSecurityMetadataSource;

    //密码加密
    @Bean
    public PasswordEncoder passwordEncoder(){
        return new BCryptPasswordEncoder();
    }
    //加密密码
    public static void main(String[] args) {
        SpringSecurityConfig springSecurityConfig = new SpringSecurityConfig();
        PasswordEncoder passwordEncoder = springSecurityConfig.passwordEncoder();
        String encode = passwordEncoder.encode("admin");
        System.out.println("加密后的密码:"+encode);

    }
    //配置访问路径


    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                //关闭csrf
                .csrf().disable()
                //不通过Session获取SecurityContext
                .sessionManagement()
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS);

        //把token校验过滤器添加到过滤器链中
        http.addFilterBefore(jwtAuthenticationTokenFilter, UsernamePasswordAuthenticationFilter.class);
        //请求需要经过权限认证
        http.authorizeRequests()
                .anyRequest()
                .authenticated()
                //自定义的元数据源和权限决策配置
                .withObjectPostProcessor(new ObjectPostProcessor<FilterSecurityInterceptor>() {
                    @Override
                    public <O extends FilterSecurityInterceptor> O postProcess(O obj) {
                        obj.setSecurityMetadataSource(urlFilterInvocationSecurityMetadataSource);
                        obj.setAccessDecisionManager(jwtAccessDeniedManager);
                        return obj;
                    }
                });
        //配置异常处理器 => 自定义的
        http.exceptionHandling()
                //配置认证失败处理器
                .authenticationEntryPoint(authenticationEntryPoint)
                .accessDeniedHandler(accessDeniedHandler);
        //允许跨域
        http.cors();
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        //使用自己的UserDetailsService
        auth.userDetailsService(userDetailsService);
    }

}

11.创建登录接口，生成封装验证信息

    /**
     * 管理员登录验证

     * @return
     */
    CommonResult login(LoginDTO loginDTO);

    User getByName(String username);
}
