Spring Boot 2.6. x似乎引入了一些更改,导致以前与Keycloak的集成具有循环引用,从而阻止应用程序启动;它在当前的2.5. x版本中正常工作和启动。
明确地说,除了
当然,预期的行为是应用程序启动正常,并像以前一样使用keyclope进行保护。
实际消息是:

Description:
The dependencies of some of the beans in the application context form a cycle:
┌──->──┐
| keycloakSecurityConfig (field private org.keycloak.adapters.KeycloakConfigResolver org.keycloak.adapters.springsecurity.config.KeycloakWebSecurityConfigurerAdapter.keycloakConfigResolver)
└──<-──┘
Action:
Relying upon circular references is discouraged and they are prohibited by default. Update your application to remove the dependency cycle between beans. As a last resort, it may be possible to break the cycle automatically by setting spring.main.allow-circular-references to true.
该POM是广泛的,因为它包含了大量的Spring启动。。。(web、安全)条目,以及其他无趣的项目依赖项。我认为与这个特定问题相关的可能是与keyclope相关的东西:
在
并作为
存在的唯一相关配置类是(为了简洁起见,删除了Javadoc):
@Configuration
@EnableWebSecurity
@ComponentScan(basePackageClasses = KeycloakSecurityComponents.class)
public class KeycloakSecurityConfig extends KeycloakWebSecurityConfigurerAdapter {
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) {
KeycloakAuthenticationProvider kap = keycloakAuthenticationProvider();
kap.setGrantedAuthoritiesMapper(new SimpleAuthorityMapper());
auth.authenticationProvider(kap);
}
@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("/**")
.authenticated();
}
}
我戳了一下Keycloak代码,似乎抽象的o. k. a. s. c. KeycloakWebSecurityConfigrerAdapter,我为上面的配置类扩展了它,它有一个@Autow的(必需=false)私有字段o. k. a. KeycloakConfigResolver-正是循环引用错误中提到的。
我尝试过:
>
将带注释的@Bean提供程序方法(返回KeyCoverConfigResolver的实现,在上面的配置类中,它只是KeyCovereSpringBootConfigResolver)移动到另一个类;导致该类也在循环引用错误中被提及,作为类路径上的一项。
只是删除返回KeycloakSpringBootConfigResolver的提供者方法,并查看是否有其他东西提供它;我意识到这没有意义,并且它按预期失败,因为这里使用的Keycloak资源没有任何变化(从15.0.2开始)-此外,如果字段为空,则获取配置的默认方法是o. k. a. s. c中的JSON文件。KeycloakWebSecurityConfigrerAdapter::adapterDeploymentContext。
更多的阅读,现在我不再理解为什么我所做的实际工作——它有一个o.k.a.KeyCloveConfigResolver的构造函数注入实例,它必须使用的提供程序本身是一个非静态方法——这意味着必须构建一个实例。根据前面的要点,注释掉我提供了o.k.a.KeyCloveConfigResolver实现的方法会导致它默认为注入字段,这是尝试JSON文件的空条件。
可能相关,但不确定;似乎不是:最近的问题在这里Spring boot keycloak循环参考
允许循环依赖可能不是最好的选择。
您可以做的一件事是为您的KeycloakConfigResolver bean创建一个特定的配置类。
