Keycloak是一个开源的身份和访问管理解决方案,它提供了单点登录(SSO)、身份验证和授权服务。Spring Boot是一个用于构建Java应用程序的框架,它简化了开发过程并提供了许多开箱即用的功能。
要将Keycloak 7与Spring Boot 2集成,可以按照以下步骤进行操作:
<dependency>
<groupId>org.keycloak</groupId>
<artifactId>keycloak-spring-boot-starter</artifactId>
<version>7.0.1</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
keycloak.realm=myrealm
keycloak.auth-server-url=http://localhost:8080/auth
keycloak.ssl-required=external
keycloak.resource=myclient
keycloak.credentials.secret=myclientsecret
@Configuration
@EnableWebSecurity
@ComponentScan(basePackageClasses = KeycloakSecurityComponents.class)
public class SecurityConfig extends KeycloakWebSecurityConfigurerAdapter {
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
KeycloakAuthenticationProvider keycloakAuthenticationProvider = keycloakAuthenticationProvider();
keycloakAuthenticationProvider.setGrantedAuthoritiesMapper(new SimpleAuthorityMapper());
auth.authenticationProvider(keycloakAuthenticationProvider);
}
@Bean
public KeycloakSpringBootConfigResolver keycloakConfigResolver() {
return new KeycloakSpringBootConfigResolver();
}
@Bean
@Override
protected SessionAuthenticationStrategy sessionAuthenticationStrategy() {
return new RegisterSessionAuthenticationStrategy(new SessionRegistryImpl());
}
@Override
protected void configure(HttpSecurity http) throws Exception {
super.configure(http);
http.authorizeRequests()
.antMatchers("/api/public").permitAll()
.antMatchers("/api/private").hasRole("user")
.anyRequest().authenticated();
}
}
@RestController
@RequestMapping("/api")
public class ApiController {
@GetMapping("/public")
public String publicEndpoint() {
return "This is a public endpoint";
}
@GetMapping("/private")
public String privateEndpoint() {
return "This is a private endpoint";
}
}
这样,就完成了Keycloak 7与Spring Boot 2的集成。通过集成Keycloak,可以实现安全的身份验证和授权,保护应用程序的API资源。
