好的,关于你的问题,我可以给你一些指导。
Spring Boot 能够轻松集成 OAuth2,实现单点登录(SSO)功能。OAuth2 是一种授权协议,允许用户在不泄露密码的情况下授权第三方应用访问他们的资源。以下是基本步骤:
1. 添加依赖项
在 pom.xml 文件中添加以下依赖项:
```
<dependency>
<groupId>org.springframework.security.oauth.boot</groupId>
<artifactId>spring-security-oauth2-autoconfigure</artifactId>
<version>2.1.0.RELEASE</version>
</dependency>
```
2. 配置 Spring Security
在 Spring Security 配置文件中添加以下代码:
```
@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
@Autowired
private AuthenticationManager authenticationManager;
@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients.inMemory()
.withClient("client-id")
.secret("client-secret")
.authorizedGrantTypes("authorization_code")
.scopes("read", "write")
.redirectUris("http://localhost:8080/login")
.and()
.withClient("client-id-2")
.secret("client-secret-2")
.authorizedGrantTypes("password")
.scopes("read", "write")
.accessTokenValiditySeconds(3600)
.and()
.withClient("client-id-3")
.secret("client-secret-3")
.authorizedGrantTypes("client_credentials")
.scopes("read", "write");
}
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
endpoints.authenticationManager(authenticationManager);
}
}
```
3. 配置资源服务器
在资源服务器配置文件中添加以下代码:
```
@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {
@Override
public void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/api/**").authenticated()
.anyRequest().permitAll();
}
}
```
4. 集成 Spring Boot
在 Spring Boot 启动类上添加注解 @EnableOAuth2Sso,示例如下:
```
@SpringBootApplication
@EnableOAuth2Sso
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
```
以上就是基本的步骤,具体实现可以参考 Spring 官方文档和示例代码。希望可以帮助到你。
