Spring Cloud实现单点登录可以使用Spring Security和OAuth2来完成。以下是一个简单的示例代码:
1. 创建一个Spring Boot项目,并添加以下依赖:
```xml
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-oauth2</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-jwt</artifactId>
</dependency>
```
2. 添加@EnableOAuth2Sso和@EnableResourceServer注解以启用单点登录和资源服务器。
```java
@SpringBootApplication
@EnableOAuth2Sso
@EnableResourceServer
public class SsoClientApplication {
public static void main(String[] args) {
SpringApplication.run(SsoClientApplication.class, args);
}
}
```
3. 配置Spring Security,设置安全规则。
```java
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.csrf().disable()
.authorizeRequests()
.anyRequest().authenticated()
.and()
.logout().logoutSuccessUrl("http://localhost:8080/logout")
.and()
.csrf().csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse());
}
}
```
4. 配置OAuth2客户端和资源服务器。
```java
@Configuration
@EnableOAuth2Client
public class OAuth2Config {
@Bean
public OAuth2RestTemplate oauth2RestTemplate(OAuth2ClientContext oauth2ClientContext, OAuth2ProtectedResourceDetails details) {
return new OAuth2RestTemplate(details, oauth2ClientContext);
}
@Bean
public OAuth2ProtectedResourceDetails resourceDetails() {
ClientCredentialsResourceDetails details = new ClientCredentialsResourceDetails();
details.setAccessTokenUri("http://localhost:8080/oauth/token");
details.setClientId("client");
details.setClientSecret("secret");
details.setGrantType("client_credentials");
details.setScope(Arrays.asList("read", "write"));
return details;
}
@Bean
public ResourceServerTokenServices tokenServices() {
RemoteTokenServices tokenServices = new RemoteTokenServices();
tokenServices.setCheckTokenEndpointUrl("http://localhost:8080/oauth/check_token");
tokenServices.setClientId("client");
tokenServices.setClientSecret("secret");
return tokenServices;
}
}
```
以上是一个简单的Spring Cloud实现单点登录的示例代码。在实际项目中,可能需要根据具体需求进行修改和调整。
