SpringBoot2.7.2整合SpringSecurity+Redis权限控制

好的，我可以为您提供一些指导。

首先，您需要在您的Spring Boot项目中添加Spring Security和Redis的依赖。

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

然后，在您的Spring Boot项目中创建一个配置类，该类将配置Spring Security和Redis的集成。

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private RedisConnectionFactory redisConnectionFactory;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/admin/**").hasRole("ADMIN")
                .antMatchers("/user/**").hasRole("USER")
                .anyRequest().authenticated()
                .and()
                .formLogin()
                .and()
                .logout()
                .logoutSuccessUrl("/");
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        RedisUserDetailsService userDetailsService = new RedisUserDetailsService(redisConnectionFactory);
        auth.userDetailsService(userDetailsService);
    }

    @Bean
    public RedisTokenRepositoryImpl redisTokenRepository() {
        return new RedisTokenRepositoryImpl(redisConnectionFactory);
    }

    @Bean
    public TokenBasedRememberMeServices rememberMeServices() {
        TokenBasedRememberMeServices rememberMeServices = new TokenBasedRememberMeServices("remember-me", userDetailsService());
        rememberMeServices.setTokenRepository(redisTokenRepository());
        return rememberMeServices;
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
}

上述配置类中的configure(HttpSecurity http)方法指定了不同角色的用户可以访问哪些URL。configure(AuthenticationManagerBuilder auth)方法指定了如何从Redis中获取用户信息。redisTokenRepository()和rememberMeServices()方法指定了如何将Remember-Me令牌存储到Redis中。

最后，在您的Spring Boot项目中创建一个RedisUserDetailsService类，该类将从Redis中获取用户信息。

public class RedisUserDetailsService implements UserDetailsService {

    private RedisConnectionFactory redisConnectionFactory;

    public RedisUserDetailsService(RedisConnectionFactory redisConnectionFactory) {
        this.redisConnectionFactory = redisConnectionFactory;
    }

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashValueSerializer(new GenericToStringSerializer<>(Object.class));
        redisTemplate.afterPropertiesSet();

        Map<Object, Object> userMap = redisTemplate.opsForHash().entries("user:" + username);
        if (userMap.isEmpty()) {
            throw new UsernameNotFoundException("User '" + username + "' not found");
        }

        String password = (String) userMap.get("password");
        List<String> authorities = (List<String>) userMap.get("authorities");

        List<GrantedAuthority> grantedAuthorities = new ArrayList<>();
        for (String authority : authorities) {
            grantedAuthorities.add(new SimpleGrantedAuthority(authority));
        }

        return new User(username, password, grantedAuthorities);
    }
}

上述类中的loadUserByUsername(String username)方法从Redis中获取用户信息。

帮我编写完整的SpringBoot2.7.2整合SpringSecurity+Redis rbac权限控制的java代码

好的，以下是完整的Spring Boot 2.7.2整合Spring Security + Redis RBAC权限控制的Java代码示例：

首先，您需要在您的Spring Boot项目中添加Spring Security和Redis的依赖。

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

接下来，创建一个User实体类，该类表示系统中的用户。

@Data
@AllArgsConstructor
@NoArgsConstructor
public class User implements UserDetails {

    private static final long serialVersionUID = -8091879091924046844L;

    private String username;
    private String password;
    private List<String> roles;

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        return roles.stream().map(SimpleGrantedAuthority::new).collect(Collectors.toList());
    }

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

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

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

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

然后，创建一个UserDetailsServiceImpl类，该类实现了UserDetailsService接口，用于从Redis中获取用户信息。

@Service
public class UserDetailsServiceImpl implements UserDetailsService {

    @Autowired
    private RedisTemplate<String, Object> redisTemplate;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        User user = (User) redisTemplate.opsForHash().get("users", username);
        if (user == null) {
            throw new UsernameNotFoundException("User not found with username: " + username);
        }
        return user;
    }
}

接下来，创建一个RBACAuthorityService类，该类用于从Redis中获取角色和权限信息。

@Service
public class RBACAuthorityService {

    @Autowired
    private RedisTemplate<String, Object> redisTemplate;

    public List<String> getRolesByUserName(String username) {
        return (List<String>) redisTemplate.opsForHash().get("roles", username);
    }

    public List<String> getPermissionsByRole(String role) {
        return (List<String>) redisTemplate.opsForHash().get("permissions", role);
    }
}

然后，创建一个RBACPermissionEvaluator类，该类实现了PermissionEvaluator接口，用于判断用户是否有权限访问某个URL。

@Component
public class RBACPermissionEvaluator implements PermissionEvaluator {

    @Autowired
    private RBACAuthorityService rbacAuthorityService;

    @Override
    public boolean hasPermission(Authentication auth, Object targetDomainObject, Object permission) {
        if (auth == null || targetDomainObject == null || !(permission instanceof String)) {
            return false;
        }

        String username = auth.getName();
        List<String> roles = rbacAuthorityService.getRolesByUserName(username);
        for (String role : roles) {
            List<String> permissions = rbacAuthorityService.getPermissionsByRole(role);
            if (permissions.contains(permission)) {
                return true;
            }
        }

        return false;
    }

    @Override
    public boolean hasPermission(Authentication auth, Serializable targetId, String targetType, Object permission) {
        return false;
    }
}

然后，您需要创建一个RedisTokenRepositoryImpl类，该类实现了PersistentTokenRepository接口，用于将Remember-Me令牌存储到Redis中。

@Repository
public class RedisTokenRepositoryImpl implements PersistentTokenRepository {

    private RedisTemplate<String, Object> redisTemplate;

    public RedisTokenRepositoryImpl(RedisConnectionFactory redisConnectionFactory) {
        this.redisTemplate = new RedisTemplate<>();
        this.redisTemplate.setConnectionFactory(redisConnectionFactory);
        this.redisTemplate.setKeySerializer(new StringRedisSerializer());
        this.redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        this.redisTemplate.setHashValueSerializer(new GenericToStringSerializer<>(Object.class));
        this.redisTemplate.afterPropertiesSet();
    }

    @Override
    public void createNewToken(PersistentRememberMeToken token) {
        redisTemplate.opsForHash().put("rememberMeTokens", token.getSeries(), token);
    }

    @Override
    public void updateToken(String series, String tokenValue, Date lastUsed) {
        PersistentRememberMeToken token = getTokenForSeries(series);
        if (token != null) {
            token.setTokenValue(tokenValue);
            token.setDate(lastUsed);
            redisTemplate.opsForHash().put("rememberMeTokens", series, token);
        }
    }

    @Override
    public PersistentRememberMeToken getTokenForSeries(String seriesId) {
        return (PersistentRememberMeToken) redisTemplate.opsForHash().get("rememberMeTokens", seriesId);
    }

    @Override
    public void removeUserTokens(String username) {
        HashOperations<String, String, PersistentRememberMeToken> ops = redisTemplate.opsForHash();
        Map<String, PersistentRememberMeToken> tokens = ops.entries("rememberMeTokens");
        for (PersistentRememberMeToken token : tokens.values()) {
            if (username.equals(token.getUsername())) {
                ops.delete("rememberMeTokens", token.getSeries());
            }
        }
    }
}

接下来，创建一个SecurityConfig类，该类用于配置Spring Security。

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private UserDetailsServiceImpl userDetailsService;

    @Autowired
    private RBACPermissionEvaluator permissionEvaluator;

    @Autowired
    private RedisConnectionFactory redisConnectionFactory;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/admin/**").hasRole("ADMIN")
                .antMatchers("/user/**").hasAnyRole("ADMIN", "USER")
                .anyRequest().authenticated()
                .and()
                .formLogin()
                .loginPage("/login").permitAll()
                .and()
                .logout().permitAll()
                .and()
                .rememberMe()
                .tokenRepository(redisTokenRepository())
                .tokenValiditySeconds(86400)
                .userDetailsService(userDetailsService);
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
    }

    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/css/**", "/js/**", "/images/**");
    }

    @Bean
    public RedisTokenRepositoryImpl redisTokenRepository() {
        return new RedisTokenRepositoryImpl(redisConnectionFactory);
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new RBACInterceptor(permissionEvaluator));
    }
}

在上述代码中，我们使用了RBACPermissionEvaluator来判断用户是否有权限访问某个URL。我们还使用了RedisTokenRepositoryImpl来将Remember-Me令牌存储到Redis中。最后，我们使用了RBACInterceptor来拦截请求并进行权限验证。在addInterceptors方法中，我们将RBACInterceptor注册到Spring MVC拦截器链中。

最后，创建一个RBACInterceptor类，该类实现了HandlerInterceptor接口，用于拦截请求并进行权限验证。

public class RBACInterceptor implements HandlerInterceptor {

    private RBACPermissionEvaluator permissionEvaluator;

    public RBACInterceptor(RBACPermissionEvaluator permissionEvaluator) {
        this.permissionEvaluator = permissionEvaluator;
    }

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        String url = request.getRequestURI();
        String method = request.getMethod();
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();

        if (authentication == null || !authentication.isAuthenticated()) {
            response.sendRedirect("/login");
            return false;
        }

        boolean hasPermission = permissionEvaluator.hasPermission(authentication, url, method);
        if (!hasPermission) {
            response.sendError(HttpServletResponse.SC_FORBIDDEN);
            return false;
        }

        return true;
    }
}

上述代码中，我们使用RBACPermissionEvaluator来判断用户是否有权限访问某个URL。如果用户没有权限访问某个URL，我们将返回HTTP 403 Forbidden错误。
