【Spring底层原理高级进阶】【SpringCloud整合Spring Security OAuth2】深入了解 Spring Security OAuth2:底层解析+使用方法+实战
Spring Cloud 整合 Spring Security OAuth2 涉及的内容较多,但我可以提供一个简化的示例来说明如何在 Spring Cloud 应用中使用 OAuth2。
- 添加依赖(pom.xml):
<dependencies>
<!-- Spring Security OAuth2 -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-oauth2</artifactId>
</dependency>
<!-- Spring Cloud Security -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-security</artifactId>
</dependency>
</dependencies>
- 配置 Security 和 OAuth2(SecurityConfig.java):
@Configuration
@EnableAuthorizationServer
public class SecurityConfig extends AuthorizationServerConfigurerAdapter {
@Autowired
private AuthenticationManager authenticationManager;
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients.inMemory()
.withClient("client")
.secret("secret")
.authorizedGrantTypes("password", "refresh_token")
.scopes("read", "write")
.accessTokenValiditySeconds(600)
.refreshTokenValiditySeconds(36000);
}
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
endpoints.authenticationManager(authenticationManager);
}
}
- 配置 Resource Server 和 Web Security(ResourceServerConfig.java):
@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {
@Override
public void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.anyRequest().authenticated();
}
}
- 使用 OAuth2 客户端访问受保护的资源:
RestTemplate restTemplate = new RestTemplate();
String accessToken = obtainAccessToken(); // 获取访问令牌的逻辑
HttpHeaders headers = new HttpHeaders();
headers.setBearerAuth(accessToken);
HttpEntity<String> entity = new HttpEntity<>(headers);
ResponseEntity<String> response = restTemplate.exchange("http://localhost:8080/api/data",
HttpMethod.GET, entity, String.class);
这个示例展示了如何配置一个 Spring Cloud 应用作为 OAuth2 授权服务器和资源服务器,并使用一个简单的 REST 模板客户端来获取受保护资源的示例。
请注意,这只是一个简化的示例,实际应用中还需要考虑更多安全性和性能因素,例如使用数据库而非内存来存储客户端和令牌信息,配置合适的密钥,使用正确的 HTTPS 设置等。
