Spring Security整合Oauth2实现流程详解
前言
在Web开发过程中,安全始终是一个重要的话题。为了保护我们的应用程序免受黑客、欺诈和恶意攻击,我们需要使用安全框架来保护它。在这方面,Spring Security是一个强大的框架,提供了多种身份认证和授权方式。在此基础上,我们还可以使用Oauth2协议来进行安全访问控制。
本文将介绍如何使用Spring Security整合Oauth2实现安全访问控制的详细步骤。
整合流程
整个流程可以分为以下几个步骤:
- 添加Maven依赖项
- 配置Spring Security和Oauth2
- 实现授权和认证服务
- 客户端使用Oauth2协议访问
添加Maven依赖项
首先,我们需要添加以下Maven依赖项:
<dependency>
<groupId>org.springframework.security.oauth</groupId>
<artifactId>spring-security-oauth2</artifactId>
<version>2.0.14.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-web</artifactId>
<version>4.2.3.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-config</artifactId>
<version>4.2.3.RELEASE</version>
</dependency>
配置Spring Security和Oauth2
接下来,我们需要在Spring Security配置文件中进行一些配置。以下是一个基本的配置文件示例:
<beans:bean id="tokenStore" class="org.springframework.security.oauth2.provider.token.InMemoryTokenStore"/>
<http pattern="/oauth/token" create-session="stateless"
authentication-manager-ref="authenticationManager"
xmlns="http://www.springframework.org/schema/security"
authorization-server-ref="oauth2AuthorizationServer"/>
<http pattern="/oauth/**"
create-session="never"
entry-point-ref="oauthAuthenticationEntryPoint"
access-decision-manager-ref="oauthAccessDecisionManager"
xmlns="http://www.springframework.org/schema/security"/>
<beans:bean id="oauth2AuthorizationServer"
class="org.springframework.security.oauth2.provider.endpoint.AuthorizationEndpoint">
<beans:property name="tokenGranter" ref="oauth2TokenGranter"/>
<beans:property name="clientDetailsService" ref="oauth2ClientDetailsService"/>

</beans:constructor-arg>
</beans:bean>
<beans:bean id="oauth2TokenGranter"

</beans:bean>
<beans:bean class="org.springframework.security.oauth2.provider.token.ImplicitTokenGranter">
<beans:constructor-arg name="tokenServices" ref="tokenServices"/>
<beans:constructor-arg name="clientDetailsService" ref="oauth2ClientDetailsService"/>
<beans:constructor-arg name="oAuth2RequestFactory" ref="oAuth2RequestFactory"/>
</beans:bean>
<beans:bean class="org.springframework.security.oauth2.provider.token.RefreshTokenGranter">
<beans:constructor-arg name="tokenServices" ref="tokenServices"/>
<beans:constructor-arg name="clientDetailsService" ref="oauth2ClientDetailsService"/>
<beans:constructor-arg name="oAuth2RequestFactory" ref="oAuth2RequestFactory"/>
</beans:bean>
</beans:list>
</beans:constructor-arg>
</beans:bean>
<beans:bean id="oauth2ClientDetailsService"
class="org.springframework.security.oauth2.provider.client.JdbcClientDetailsService">
<beans:constructor-arg name="dataSource" ref="dataSource"/>
</beans:bean>
<beans:bean id="oauth2AuthorizationCodeServices"
class="org.springframework.security.oauth2.provider.code.JdbcAuthorizationCodeServices">
<beans:constructor-arg name="dataSource" ref="dataSource"/>
</beans:bean>
<beans:bean id="oauth2RedirectResolver"
class="org.springframework.security.oauth2.provider.endpoint.DefaultRedirectResolver"/>
<beans:bean id="oauth2UserApprovalHandler"
class="org.springframework.security.oauth2.provider.approval.DefaultUserApprovalHandler">
<beans:property name="approvalStore" ref="oauth2ApprovalStore"/>
<beans:property name="clientDetailsService" ref="oauth2ClientDetailsService"/>
<beans:property name="useApprovalStore" value="true"/>
</beans:bean>
<beans:bean id="oauth2ApprovalStore"
class="org.springframework.security.oauth2.provider.approval.JdbcApprovalStore">
<beans:constructor-arg name="dataSource" ref="dataSource"/>
</beans:bean>
<oauth:authorization-server client-details-service-ref="oauth2ClientDetailsService"
token-services-ref="tokenServices">

<oauth:implicit/>
<oauth:refresh-token/>

<oauth:password authentication-manager-ref="authenticationManager"/>
</oauth:authorization-server>
<oauth:resource-server token-services-ref="tokenServices"/>
<beans:bean id="oAuth2RequestFactory"
class="org.springframework.security.oauth2.provider.request.DefaultOAuth2RequestFactory">
<beans:constructor-arg name="clientDetailsService" ref="oauth2ClientDetailsService"/>
</beans:bean>
<beans:bean id="jdbcTokenStore"
class="org.springframework.security.oauth2.provider.token.store.JdbcTokenStore">
<beans:constructor-arg name="dataSource" ref="dataSource"/>
</beans:bean>
<beans:bean id="tokenServices"
class="org.springframework.security.oauth2.provider.token.DefaultTokenServices">
<beans:property name="tokenStore" ref="jdbcTokenStore"/>
<beans:property name="supportRefreshToken" value="true"/>
<beans:property name="clientDetailsService" ref="oauth2ClientDetailsService"/>
<beans:property name="accessTokenValiditySeconds" value="1800"/>
<beans:property name="refreshTokenValiditySeconds" value="7200"/>
</beans:bean>
<authentication-manager alias="authenticationManager">
<authentication-provider>
<user-service>
<user name="admin" password="admin" authorities="ROLE_USER, ROLE_ADMIN"/>
<user name="user" password="user" authorities="ROLE_USER"/>
</user-service>
</authentication-provider>
</authentication-manager>
在以上配置中,我们定义了一个基本的Spring Security配置,并且使用了OAuth2协议对访问控制进行处理。
实现授权和认证服务
现在,我们来实现授权和认证服务。我们可以使用Spring MVC框架来完成这项工作。以下是一个示例代码:
@RestController
public class AuthController {
@Autowired
private ClientDetailsService clientDetailsService;
private TokenStore tokenStore = new InMemoryTokenStore();
@RequestMapping(value = "/oauth/token", method = RequestMethod.POST)
public ResponseEntity<?> createAuthenticationToken(@RequestBody OAuth2Request oAuth2Request,
HttpServletRequest request) throws Exception {
ClientDetails client = clientDetailsService.loadClientByClientId(oAuth2Request.getClientId());
TokenRequest tokenRequest = new TokenRequest(MapUtils.EMPTY_MAP, client.getClientId(),
client.getScope(), "password");
OAuth2Authentication auth = new OAuth2Authentication(oAuth2Request, null);
auth.setAuthenticated(true);
OAuth2AccessToken accessToken = tokenServices.createAccessToken(new OAuth2AuthenticationToken(auth));
return new ResponseEntity<OAuth2AccessToken>(accessToken, HttpStatus.OK);
}
}
在这个授权服务器中,我们使用了Spring MVC框架来处理http请求。我们使用了OAuth2协议进行身份认证和授权,并且将令牌存储在redis中。
客户端使用Oauth2协议访问
现在,我们已经完成了OAuth2授权服务器的配置和实现,接下来我们需要了解如何使用Oauth2协议访问它。
以下代码演示了如何使用Oauth2协议在Spring Boot中访问授权服务器:
@SpringBootApplication
@EnableOAuth2Client
@Controller
public class ClientApplication extends WebSecurityConfigurerAdapter {
@Autowired
OAuth2ClientContext oAuth2ClientContext;
public static void main(String[] args) {
SpringApplication.run(ClientApplication.class, args);
}
@RequestMapping("/user")
@ResponseBody
public Map<String, Object> user(OAuth2AuthenticationToken authentication) {
return authentication.getPrincipal().getAttributes();
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests(authorize -> authorize
.anyRequest().authenticated()
)
.oauth2Login()
.and()
.logout(logout -> logout
.logoutSuccessUrl("/").permitAll()
);
}
@Bean
public OAuth2RestTemplate oauth2RestTemplate(OAuth2ProtectedResourceDetails resource, OAuth2ClientContext context) {
return new OAuth2RestTemplate(resource, context);
}
@Bean
public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
return new PropertySourcesPlaceholderConfigurer();
}
@Bean
public ClientCredentialsResourceDetails resourceDetails() {
ClientCredentialsResourceDetails resource = new ClientCredentialsResourceDetails();
resource.setAccessTokenUri("http://localhost:8080/oauth/token");
resource.setClientId("your-client-id");
resource.setClientSecret("your-client-secret");
return resource;
}
@Bean
public RestTemplate restTemplate() {
return new RestTemplate();
}
}
在这个客户端示例中,我们使用了OAuth2协议对访问授权服务器进行了处理,并且使用了Spring Boot框架来处理http请求。
