Spring Cloud Security 为构建安全的SpringBoot应用提供了一系列解决方案,结合Oauth2还能够实现更多功能,好比使用JWT令牌存储信息,刷新令牌功能,本文将对其结合JWT使用进行详细介绍。git
JWT是JSON WEB TOKEN的缩写,它是基于 RFC 7519 标准定义的一种能够安全传输的的JSON对象,因为使用了数字签名,因此是可信任和安全的。github
{
"alg": "HS256",
"typ": "JWT"
}

该模块只是对oauth2-server模块的扩展,直接复制过来扩展下下便可。web
在上一节中咱们都是把令牌存储在内存中的,这样若是部署多个服务,就会致使没法使用令牌的问题。 Spring Cloud Security中有两种存储令牌的方式可用于解决该问题,一种是使用Redis来存储,另外一种是使用JWT来存储。redis
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

redis: #redis相关配置
password: 123456 #有密码时设置

有时候咱们须要扩展JWT中存储的内容,这里咱们在JWT中扩展一个key为
enhance
,value为enhance info
的数据。算法
/** * Jwt内容加强器 * Created by macro on 2019/10/8. */
public class JwtTokenEnhancer implements TokenEnhancer {
@Override
public OAuth2AccessToken enhance(OAuth2AccessToken accessToken, OAuth2Authentication authentication) {
Map<String, Object> info = new HashMap<>();
info.put("enhance", "enhance info");
((DefaultOAuth2AccessToken) accessToken).setAdditionalInformation(info);
return accessToken;
}
}
复制代码
/** * 使用Jwt存储token的配置 * Created by macro on 2019/10/8. */
@Configuration
public class JwtTokenStoreConfig {
//省略代码...
@Bean
public JwtTokenEnhancer jwtTokenEnhancer() {
return new JwtTokenEnhancer();
}
}

/** * 认证服务器配置 * Created by macro on 2019/9/30. */

private AuthenticationManager authenticationManager;

private TokenStore tokenStore;

@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
TokenEnhancerChain enhancerChain = new TokenEnhancerChain();
List<TokenEnhancer> delegates = new ArrayList<>();
delegates.add(jwtTokenEnhancer); //配置JWT的内容加强器
delegates.add(jwtAccessTokenConverter);
enhancerChain.setTokenEnhancers(delegates);
endpoints.authenticationManager(authenticationManager)
.userDetailsService(userService)
.tokenStore(tokenStore) //配置令牌存储策略
.accessTokenConverter(jwtAccessTokenConverter)
.tokenEnhancer(enhancerChain);
}
//省略代码...
}

若是咱们须要获取JWT中的信息,可使用一个叫jjwt的工具包。spring
<dependency>
<groupId>io.jsonwebtoken</groupId>
<artifactId>jjwt</artifactId>
<version>0.9.0</version>
</dependency>
复制代码
/** * Created by macro on 2019/9/30. */
@RestController
@RequestMapping("/user")
public class UserController {
@GetMapping("/getCurrentUser")
public Object getCurrentUser(Authentication authentication, HttpServletRequest request) {
String header = request.getHeader("Authorization");
String token = StrUtil.subAfter(header, "bearer ", false);
return Jwts.parser()
.setSigningKey("test_key".getBytes(StandardCharsets.UTF_8))
.parseClaimsJws(token)
.getBody();
}
}
复制代码
Authorization
头中,访问以下地址获取信息:http://localhost:9401/user/getCurrentUser在Spring Cloud Security 中使用oauth2时,若是令牌失效了,可使用刷新令牌经过refresh_token的受权模式再次获取access_token。json
/** * 认证服务器配置 * Created by macro on 2019/9/30. */
@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients.inMemory()
.withClient("admin")
.secret(passwordEncoder.encode("admin123456"))
.accessTokenValiditySeconds(3600)
.refreshTokenValiditySeconds(864000)
.redirectUris("http://www.baidu.com")
.autoApprove(true) //自动受权配置
.scopes("all")
.authorizedGrantTypes("authorization_code","password","refresh_token"); //添加受权模式
}
}
