Spring Boot Sping Boot 2.6回归：如何修复适配器中的Keycloak循环依赖？

Boot 似乎引入了一些变化，导致之前与Keycloak的集成有一个循环引用，阻止应用程序启动;它在当前的2.5.x版本中运行良好。
明确地说，通过**在spring-boot-starter-parent中仅将标记值从2.5.7更改为2.6.1**，将出现以下详细说明的错误/消息。
当然，预期的行为是应用程序启动良好，并且像以前一样使用Keycloak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.

POM非常广泛，因为它包含了大量的spring-boot-starter-...（web，security）条目，沿着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Keycloak相关的东西：
在：

  • org.keycloak.bom：keycloak-adapter-bom：15.0.2（通过POM变量固定的版本）

作为条目（预期来自spring-boot-starter-parent或Keycloak BOM的版本）：

  • Boot ：启动启动程序安全性
  • org.keycloak：键盘锁-Spring-启动器

存在的唯一相关配置类是（为简洁起见，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();
    }

}

我已经对Keycloak代码做了一些修改，我为上面的config类扩展的抽象o.k.a.s.c.KeycloakWebSecurityConfigurerAdapter似乎有一个o.k.a.KeycloakConfigResolver类型的@Autowired（required = false）私有字段--正是循环引用错误中提到的。
我试过了：

  • 将返回KeycloakConfigResolver（在我上面的配置类中，它只是KeycloakSpringBootConfigResolver）实现的提供程序方法@Bean移动到一个不同的类;导致该类也作为类路径中的一个项出现在循环引用错误中。
  • 只是删除返回KeycloakSpringBootConfigResolver的提供程序方法，并查看是否有其他东西提供它;我意识到这没有意义，并且它如预期的那样失败了，因为这里使用的Keycloak资源（从15.0.2）中没有任何变化-此外，如果字段为空，则获取配置的默认方法是o.k.a.s.c.KeycloakWebSecurityConfigurerAdapter::adapterDeploymentContext中的JSON文件。
  • 更多的阅读，现在对我来说不再有意义为什么我有实际工作-它有一个构造器注入的示例o.k.a.KeycloakConfigResolver，它必须一直使用的提供者是一个非静态方法本身-这意味着一个示例必须已经被构造。注解掉我的方法（该方法提供了KeycloakConfigResolver的实现）会导致它在尝试JSON文件时默认为injected-field-is-null条件。

可能相关的，但不确定的;似乎不是：最近的问题Spring boot keycloak circular reference

spring-boot

允许循环依赖关系可能不是最好的选择。
您可以为KeycloakConfigResolverbean创建一个特定的配置类。

package com.stackoverflow;

import org.keycloak.adapters.springboot.KeycloakSpringBootConfigResolver;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class KeycloakConfiguration {

    @Bean
    public KeycloakSpringBootConfigResolver KeycloakConfigResolver() {
        return new KeycloakSpringBootConfigResolver();
    }
}

为KeycloakConfigResolver创建特定的配置类仍然适用于Sping Boot 2.7.5和Keycloak 20.0.0

2022更新

不要将keycloak适配器用于Springit is very deprecated。
Use spring-boot-starter-oauth2-resource-server instead（如果您的应用还提供Thymeleaf或类似的UI，则为spring-boot-starter-oauth2-client）。
配置资源服务器（REST API）非常简单（下面使用一个围绕spring-boot-starter-oauth2-resource-server的瘦 Package 器）：
第一个
另外，上述示例中的5.x libs可以与 Boot 2.6和更早版本一起使用。github repo的The 5.x branch也有带keycloakSpring适配器的a working sample（但同样，您最好不要使用它）
