升级到 Spring Boot 2.6 时 Spring 安全和 org.springdoc.ui.SwaggerConfig 之间的循环引用

Question

将我的应用程序从 Spring Boot 2.5 升级到 2.6 时，出现此错误：

Error creating bean with name 'securityConfig': Unsatisfied dependency expressed through method 'setContentNegotationStrategy' parameter 0;

nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.web.servlet.WebMvcAutoConfiguration$EnableWebMvcConfiguration': Unsatisfied dependency expressed through method 'setConfigurers' parameter 0;

nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springdoc.ui.SwaggerConfig': Unsatisfied dependency expressed through field 'swaggerIndexTransformer';

nested exception is org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'org.springdoc.ui.SwaggerConfig': Requested bean is currently in creation: Is there an unresolvable circular reference?

此错误记录在 https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.6-Release-Notes#circular-references-prohibited-by-default 上，我知道我可以通过设置属性并返回到 Spring Boot 2.5 行为来“修复”它。但是如果我可以的话趁机修复一个循环引用，我不妨为将来做。

我的 securityConfig 很简单，因为我的应用程序是一个 public 应用程序，向所有调用者返回一些 html 内容，无需身份验证。所以这是我的配置：

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

  @Override
  protected void configure(HttpSecurity security) throws Exception {
    //application is open to everyone - no security
    security.httpBasic().disable();
  }
}

错误提到的 setContentNegotationStrategy 是 WebSecurityConfigurerAdapter 中的一个方法，我没有覆盖它，所以我无法理解我需要做什么。

如果我删除我的 SecurityConfig class，那么我仍然有一个错误，和以前一样，但没有提到我的 SecurityConfig class:

Error creating bean with name 'org.springframework.boot.autoconfigure.web.servlet.WebMvcAutoConfiguration$EnableWebMvcConfiguration': Unsatisfied dependency expressed through method 'setConfigurers' parameter 0;

nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springdoc.ui.SwaggerConfig': Unsatisfied dependency expressed through field 'swaggerIndexTransformer';

nested exception is org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'org.springdoc.ui.SwaggerConfig': Requested bean is currently in creation: Is there an unresolvable circular reference?

处理 Spring 安全和 org.springdoc.ui.SwaggerConfig 之间看似循环引用的推荐方法是什么？

Answer 1

问题是由 org.springdoc.ui.SwaggerConfig 引起的。它已被 these changes which are available in springdocs-openapi 1.5.13.
