springboot shiro jwt redis

Spring Boot是一个基于Spring框架的快速应用开发工具，可以简化Spring应用的创建和配置。

Apache Shiro是一个强大且灵活的Java安全框架，可用于身份验证，授权，加密和会话管理。

JWT(JSON Web Token)是一种开放标准（RFC 7519），它定义了一种简洁的自包含方式，用于在各方之间安全地传输信息。

Redis是一个开源的内存数据库，支持存储键值对数据，常用于缓存和消息队列等。

springboot+jwt+shiro+redis例子

可以的，我可以为您提供一个基于Spring Boot、JWT、Shiro和Redis的例子。这个例子将演示如何使用这些技术实现用户认证和授权，并且将用户的状态存储在Redis中。

首先，您需要创建一个Spring Boot项目并添加所需的依赖。

在pom.xml文件中添加以下依赖：

<dependencies>
    <!-- Spring Boot -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <!-- Shiro -->
    <dependency>
        <groupId>org.apache.shiro</groupId>
        <artifactId>shiro-spring-boot-web-starter</artifactId>
        <version>1.7.1</version>
    </dependency>

    <!-- JWT -->
    <dependency>
        <groupId>io.jsonwebtoken</groupId>
        <artifactId>jjwt</artifactId>
        <version>0.9.1</version>
    </dependency>

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

接下来，创建一个名为`JwtUtils`的JWT工具类，用于生成和验证JWT令牌。您可以参考以下代码：

import io.jsonwebtoken.Claims;
import io.jsonwebtoken.Jwts;
import io.jsonwebtoken.SignatureAlgorithm;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

import javax.annotation.PostConstruct;
import java.util.Date;

@Component
public class JwtUtils {

    @Value("${jwt.secret}")
    private String secret;

    @Value("${jwt.expiration}")
    private int expiration;

    @PostConstruct
    public void init() {
        secret = Base64.getEncoder().encodeToString(secret.getBytes());
    }

    public String generateToken(String username) {
        Date now = new Date();
        Date expiryDate = new Date(now.getTime() + expiration * 1000);

        return Jwts.builder()
                .setSubject(username)
                .setIssuedAt(now)
                .setExpiration(expiryDate)
                .signWith(SignatureAlgorithm.HS512, secret)
                .compact();
    }

    public String getUsernameFromToken(String token) {
        Claims claims = Jwts.parser()
                .setSigningKey(secret)
                .parseClaimsJws(token)
                .getBody();

        return claims.getSubject();
    }

    public boolean validateToken(String token) {
        try {
            Jwts.parser().setSigningKey(secret).parseClaimsJws(token);
            return true;
        } catch (Exception e) {
            return false;
        }
    }
}

然后，创建一个名为`RedisUtils`的Redis工具类，用于操作Redis。您可以参考以下代码：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Component;

import java.util.concurrent.TimeUnit;

@Component
public class RedisUtils {

    @Autowired
    private RedisTemplate<String, Object> redisTemplate;

    public void set(String key, Object value, long expiration) {
        redisTemplate.opsForValue().set(key, value, expiration, TimeUnit.SECONDS);
    }

    public Object get(String key) {
        return redisTemplate.opsForValue().get(key);
    }

    public void delete(String key) {
        redisTemplate.delete(key);
    }

    public boolean hasKey(String key) {
        return redisTemplate.hasKey(key);
    }
}

接下来，创建一个名为`JwtRealm`的Shiro Realm，用于验证JWT令牌和授权。您可以参考以下代码：

import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;

public class JwtRealm extends AuthorizingRealm {

    @Autowired
    private JwtUtils jwtUtils;

    @Autowired
    private RedisUtils redisUtils;

    @Override
    public boolean supports(AuthenticationToken token) {
        return token instanceof JwtToken;
    }

    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        // TODO: 实现授权逻辑
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        JwtToken jwtToken = (JwtToken) token;
        String username = jwtUtils.getUsernameFromToken(jwtToken.getToken());

        if (username == null || !jwtUtils.validateToken(jwtToken.getToken())) {
            throw new AuthenticationException("无效的令牌");
        }

        // TODO: 查询用户信息并返回认证信息

        return new SimpleAuthenticationInfo(username, jwtToken.getToken(), getName());
    }
}

最后，创建一个名为`JwtToken`的Shiro Token，用于封装JWT令牌。您可以参考以下代码：

import org.apache.shiro.authc.AuthenticationToken;

public class JwtToken implements AuthenticationToken {

    private String token;

    public JwtToken(String token) {
        this.token = token;
    }

    @Override
    public Object getPrincipal() {
        return token;
    }

    @Override
    public Object getCredentials() {
        return token;
    }
}

以上是一个基于Spring Boot、JWT、Shiro和Redis的例子。您可以根据您的需求进行修改和扩展。希望对您有帮助！

springboot整和jwt、shiro、redis

Spring Boot可以集成JWT、Shiro和Redis来实现身份认证和授权，以下是一个基本的实现步骤：

1. 集成JWT

<dependency>
    <groupId>io.jsonwebtoken</groupId>
    <artifactId>jjwt</artifactId>
    <version>0.9.1</version>
</dependency>

创建JWT工具类

public class JwtUtils {
    private static final String SECRET_KEY = "jwt_secret_key";
    private static final long EXPIRATION_TIME = 864_000_000; // 10天

    public static String generateToken(String subject) {
        return Jwts.builder()
                .setSubject(subject)
                .setExpiration(new Date(System.currentTimeMillis() + EXPIRATION_TIME))
                .signWith(SignatureAlgorithm.HS512, SECRET_KEY)
                .compact();
    }

    public static String getSubject(String token) {
        try {
            return Jwts.parser().setSigningKey(SECRET_KEY).parseClaimsJws(token).getBody().getSubject();
        } catch (JwtException e) {
            return null;
        }
    }
}

使用JWT进行身份认证

@RestController
@RequestMapping("/api")
public class UserController {
    @PostMapping("/login")
    public ResponseEntity<?> login(@RequestBody LoginRequest loginRequest) {
        // 验证用户名密码
        if (userValid(loginRequest.getUsername(), loginRequest.getPassword())) {
            String token = JwtUtils.generateToken(loginRequest.getUsername());
            return ResponseEntity.ok(new JwtResponse(token));
        } else {
            return ResponseEntity.status(HttpStatus.UNAUTHORIZED).build();
        }
    }

    @GetMapping("/user")
    public ResponseEntity<?> getUser(@RequestHeader("Authorization") String authHeader) {
        String token = authHeader.substring(7);
        String subject = JwtUtils.getSubject(token);
        if (subject != null) {
            User user = getUserByUsername(subject);
            return ResponseEntity.ok(user);
        } else {
            return ResponseEntity.status(HttpStatus.UNAUTHORIZED).build();
        }
    }
}

2. 集成Shiro

添加依赖

    @Bean
    public Realm realm() {
        return new UserRealm();
    }

    @Bean
    public DefaultWebSecurityManager securityManager() {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(realm());
        return securityManager;
    }

    @Bean
    public ShiroFilterFactoryBean shiroFilterFactoryBean() {
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        shiroFilterFactoryBean.setSecurityManager(securityManager());
        Map<String, String> filterChainDefinitionMap = new LinkedHashMap<>();
        filterChainDefinitionMap.put("/api/login", "anon");
        filterChainDefinitionMap.put("/api/logout", "logout");
        filterChainDefinitionMap.put("/api/**", "authc");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
        return shiroFilterFactoryBean;
    }

    @Bean
    public ShiroFilterChainDefinition shiroFilterChainDefinition() {
        DefaultShiroFilterChainDefinition chainDefinition = new DefaultShiroFilterChainDefinition();
        chainDefinition.addPathDefinition("/api/login", "anon");
        chainDefinition.addPathDefinition("/api/logout", "logout");
        chainDefinition.addPathDefinition("/api/**", "authc");
        return chainDefinition;
    }
}

创建UserRealm

public class UserRealm extends AuthorizingRealm {
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        String username = (String) principals.getPrimaryPrincipal();
        Set<String> roles = getUserRoles(username);
        Set<String> permissions = getUserPermissions(username);
        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
        authorizationInfo.setRoles(roles);
        authorizationInfo.setStringPermissions(permissions);
        return authorizationInfo;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        String username = (String) token.getPrincipal();
        String password = getPasswordByUsername(username);
        if (password == null) {
            throw new UnknownAccountException();
        }
        return new SimpleAuthenticationInfo(username, password, getName());
    }
}

使用Shiro进行身份认证

@RestController
@RequestMapping("/api")
public class UserController {
    @PostMapping("/login")
    public ResponseEntity<?> login(@RequestBody LoginRequest loginRequest) {
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken(loginRequest.getUsername(), loginRequest.getPassword());
        try {
            subject.login(token);
            String jwtToken = JwtUtils.generateToken(loginRequest.getUsername());
            return ResponseEntity.ok(new JwtResponse(jwtToken));
        } catch (AuthenticationException e) {
            return ResponseEntity.status(HttpStatus.UNAUTHORIZED).build();
        }
    }

    @GetMapping("/user")
    public ResponseEntity<?> getUser() {
        Subject subject = SecurityUtils.getSubject();
        if (subject.isAuthenticated()) {
            String username = (String) subject.getPrincipal();
            User user = getUserByUsername(username);
            return ResponseEntity.ok(user);
        } else {
            return ResponseEntity.status(HttpStatus.UNAUTHORIZED).build();
        }
    }

    @PostMapping("/logout")
    public ResponseEntity<?> logout() {
        Subject subject = SecurityUtils.getSubject();
        subject.logout();
        return ResponseEntity.ok().build();
    }
}

3. 集成Redis

添加依赖

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

配置Redis

@Configuration
public class RedisConfig {
    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(factory);
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(new Jackson2JsonRedisSerializer<>(Object.class));
        return redisTemplate;
    }

    @Bean
    public CacheManager cacheManager(RedisConnectionFactory factory) {
        RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig()
                .entryTtl(Duration.ofHours(1));
        return RedisCacheManager.builder(factory)
                .cacheDefaults(config)
                .build();
    }
}

实现Redis缓存

@Service
public class UserServiceImpl implements UserService {
    private final UserRepository userRepository;
    private final RedisTemplate<String, User> redisTemplate;
    private final CacheManager cacheManager;

    public UserServiceImpl(UserRepository userRepository, RedisTemplate<String, User> redisTemplate, CacheManager cacheManager) {
        this.userRepository = userRepository;
        this.redisTemplate = redisTemplate;
        this.cacheManager = cacheManager;
    }

    @Override
    public User getUserById(Long id) {
        String key = "user:" + id;
        ValueOperations<String, User> ops = redisTemplate.opsForValue();
        if (redisTemplate.hasKey(key)) {
            return ops.get(key);
        } else {
            User user = userRepository.findById(id).orElse(null);
            if (user != null) {
                ops.set(key, user);
                Cache cache = cacheManager.getCache("userCache");
                if (cache != null) {
                    cache.put(key, user);
                }
            }
            return user;
        }
    }

    @Override
    public void updateUser(User user) {
        userRepository.save(user);
        String key = "user:" + user.getId();
        redisTemplate.delete(key);
        Cache cache = cacheManager.getCache("userCache");
        if (cache != null) {
            cache.evict(key);
        }
    }
}

以上是整合Spring Boot、JWT、Shiro和Redis的基本实现步骤，具体实现可以根据自己的需求进行调整和扩展。
