以下是Java实现OAuth2单点登录的代码示例:
```java
// 引用[1]
// 导入相关依赖
import org.springframework.security.oauth2.client.OAuth2RestTemplate;
import org.springframework.security.oauth2.client.token.grant.code.AuthorizationCodeResourceDetails;
import org.springframework.security.oauth2.client.token.grant.code.AuthorizationCodeAccessTokenProvider;
import org.springframework.security.oauth2.client.token.AccessTokenRequest;
import org.springframework.security.oauth2.client.token.AccessTokenProvider;
import org.springframework.security.oauth2.client.token.grant.code.AuthorizationCodeResourceDetails;
import org.springframework.security.oauth2.client.token.grant.code.AuthorizationCodeAccessTokenProvider;
import org.springframework.security.oauth2.client.token.AccessTokenRequest;
import org.springframework.security.oauth2.client.token.AccessTokenProvider;
import org.springframework.security.oauth2.client.token.grant.code.AuthorizationCodeResourceDetails;
import org.springframework.security.oauth2.client.token.grant.code.AuthorizationCodeAccessTokenProvider;
import org.springframework.security.oauth2.client.token.AccessTokenRequest;
import org.springframework.security.oauth2.client.token.AccessTokenProvider;
// 创建OAuth2RestTemplate实例
AuthorizationCodeResourceDetails resourceDetails = new AuthorizationCodeResourceDetails();
resourceDetails.setClientId("your_client_id");
resourceDetails.setClientSecret("your_client_secret");
resourceDetails.setAccessTokenUri("https://oauth2.example.com/token");
resourceDetails.setUserAuthorizationUri("https://oauth2.example.com/authorize");
resourceDetails.setScope(Arrays.asList("read", "write"));
AccessTokenRequest accessTokenRequest = new DefaultAccessTokenRequest();
AccessTokenProvider accessTokenProvider = new AuthorizationCodeAccessTokenProvider();
OAuth2RestTemplate restTemplate = new OAuth2RestTemplate(resourceDetails, new DefaultOAuth2ClientContext(accessTokenRequest));
restTemplate.setAccessTokenProvider(accessTokenProvider);
// 使用OAuth2RestTemplate发送请求
String result = restTemplate.getForObject("https://api.example.com/data", String.class);
System.out.println(result);
```
请注意,上述代码仅为示例,实际使用时需要根据具体的OAuth2服务提供商和授权方式进行相应的配置和调整。
