Spring-Security实现登录接口流程
作者:韭菜盖饭
简介
Security
是 Spring
家族中的一个安全管理框架。相比与另外一个安全框架Shiro
,它提供了更丰富的功能,社区资源也比Shiro丰富。
具体介绍和入门看springSecurity入门
原理初探
在实现之前幺要了解一下登录校验的流程以及SpringSecurity
的原理以及认证流程
1、登录校验流程
2、 SpringSecurity完整流程
SpringSecurity
的原理其实就是一个过滤器链,内部包含了提供各种功能的过滤器。这里我们可以看看入门案例中的过滤器。
图中只展示了核心过滤器,其它的非核心过滤器并没有在图中展示。
UsernamePasswordAuthenticationFilter:负责处理我们在登陆页面填写了用户名密码后的登陆请求。入门案例的认证工作主要有它负责。
ExceptionTranslationFilter:处理过滤器链中抛出的任何AccessDeniedException
和AuthenticationException
。
FilterSecurityInterceptor:负责权限校验的过滤器。
我们可以通过Debug
查看当前系统中SpringSecurity
过滤器链中有哪些过滤器及它们的顺序。
3、认证流程
概念速查:
Authentication
接口: 它的实现类,表示当前访问系统的用户,封装了用户相关信息。AuthenticationManager
接口:定义了认证Authentication的方法UserDetailsService
接口:加载用户特定数据的核心接口。里面定义了一个根据用户名查询用户信息的方法。UserDetails
接口:提供核心用户信息。通过UserDetailsService
根据用户名获取处理的用户信息要封装成UserDetails
对象返回。然后将这些信息封装到Authentication
对象中。
实现思路
登录
①自定义登录接口
调用ProviderManager
的方法进行认证 如果认证通过生成jwt
把用户信息存入redis
中
②自定义UserDetailsService
在这个实现类中去查询数据库
校验:
①定义Jwt认证过滤器
获取token
解析token
获取其中的userid
从redis
中获取用户信息
存入SecurityContextHolder
这里我们主要是实现登录接口的功能
核心思想就是就是将认证流程
中的UserDetailsService
重写其loadUserByUsername
的方法,使其从数据库中查询数据,然后用自己的类(我这里是UserLogin
)实现UserDetails
,在loadUserByUsername
中返回UserLogin
登录接口实现
准备工作
添加依赖,添加工具类,创建数据库,编写配置文件
1、添加依赖
<!--redis依赖--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> </dependency> <!--fastjson依赖--> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.33</version> </dependency> <!--jwt依赖--> <dependency> <groupId>io.jsonwebtoken</groupId> <artifactId>jjwt</artifactId> <version>0.9.0</version> </dependency> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>3.4.3</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency>
2、添加Redis相关配置
import com.alibaba.fastjson.JSON; import com.alibaba.fastjson.serializer.SerializerFeature; import com.fasterxml.jackson.databind.JavaType; import com.fasterxml.jackson.databind.ObjectMapper; import com.fasterxml.jackson.databind.type.TypeFactory; import org.springframework.data.redis.serializer.RedisSerializer; import org.springframework.data.redis.serializer.SerializationException; import com.alibaba.fastjson.parser.ParserConfig; import org.springframework.util.Assert; import java.nio.charset.Charset; /** * Redis使用FastJson序列化 * * @author sg */ public class FastJsonRedisSerializer<T> implements RedisSerializer<T> { public static final Charset DEFAULT_CHARSET = Charset.forName("UTF-8"); private Class<T> clazz; static { ParserConfig.getGlobalInstance().setAutoTypeSupport(true); } public FastJsonRedisSerializer(Class<T> clazz) { super(); this.clazz = clazz; } @Override public byte[] serialize(T t) throws SerializationException { if (t == null) { return new byte[0]; } return JSON.toJSONString(t, SerializerFeature.WriteClassName).getBytes(DEFAULT_CHARSET); } @Override public T deserialize(byte[] bytes) throws SerializationException { if (bytes == null || bytes.length <= 0) { return null; } String str = new String(bytes, DEFAULT_CHARSET); return JSON.parseObject(str, clazz); } protected JavaType getJavaType(Class<?> clazz) { return TypeFactory.defaultInstance().constructType(clazz); } }
import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.data.redis.connection.RedisConnectionFactory; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.data.redis.serializer.StringRedisSerializer; @Configuration public class RedisConfig { @Bean @SuppressWarnings(value = { "unchecked", "rawtypes" }) public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory connectionFactory) { RedisTemplate<Object, Object> template = new RedisTemplate<>(); template.setConnectionFactory(connectionFactory); FastJsonRedisSerializer serializer = new FastJsonRedisSerializer(Object.class); // 使用StringRedisSerializer来序列化和反序列化redis的key值 template.setKeySerializer(new StringRedisSerializer()); template.setValueSerializer(serializer); // Hash的key也采用StringRedisSerializer的序列化方式 template.setHashKeySerializer(new StringRedisSerializer()); template.setHashValueSerializer(serializer); template.afterPropertiesSet(); return template; } }
封装返回的数据
import com.fasterxml.jackson.annotation.JsonInclude; @JsonInclude(JsonInclude.Include.NON_NULL) public class ResponseResult<T> { /** * 状态码 */ private Integer code; /** * 提示信息,如果有错误时,前端可以获取该字段进行提示 */ private String msg; /** * 查询到的结果数据, */ private T data; public ResponseResult(Integer code, String msg) { this.code = code; this.msg = msg; } public ResponseResult(Integer code, T data) { this.code = code; this.data = data; } public Integer getCode() { return code; } public void setCode(Integer code) { this.code = code; } public String getMsg() { return msg; } public void setMsg(String msg) { this.msg = msg; } public T getData() { return data; } public void setData(T data) { this.data = data; } public ResponseResult(Integer code, String msg, T data) { this.code = code; this.msg = msg; this.data = data; } }
JWT工具类
import io.jsonwebtoken.Claims; import io.jsonwebtoken.JwtBuilder; import io.jsonwebtoken.Jwts; import io.jsonwebtoken.SignatureAlgorithm; import javax.crypto.SecretKey; import javax.crypto.spec.SecretKeySpec; import java.util.Base64; import java.util.Date; import java.util.UUID; /** * 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(){ 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) { SignatureAlgorithm signatureAlgorithm = SignatureAlgorithm.HS256; 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); } /** * 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(); } public static void main(String[] args) throws Exception { String token = "eyJhbGciOiJIUzI1NiJ9.eyJqdGkiOiJjYWM2ZDVhZi1mNjVlLTQ0MDAtYjcxMi0zYWEwOGIyOTIwYjQiLCJzdWIiOiJzZyIsImlzcyI6InNnIiwiaWF0IjoxNjM4MTA2NzEyLCJleHAiOjE2MzgxMTAzMTJ9.JVsSbkP94wuczb4QryQbAke3ysBDIL5ou8fWsbt_ebg"; Claims claims = parseJWT(token); System.out.println(claims); } /** * 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(); } }

效果展示
注意:测试时要打开redis
,数据库中的密码必须是加密后的
可以使用一下方法进行加密,passwordEncoder
是SecurityConfig
中已经注入的
@Resource private PasswordEncoder passwordEncoder; String encode = passwordEncoder.encode("123456"); System.out.println(encode);
