我正在使用 Spring Security 開(kāi)發(fā) Spring Boot 應(yīng)用程序，但無(wú)法以任何方式運(yùn)行。我想使用 Spring Security 5，但此時(shí)我什至不知道我要使用哪個(gè)版本，使用 WebFlux 也無(wú)濟(jì)于事。問(wèn)題是，當(dāng)我創(chuàng)建一個(gè)擴(kuò)展 WebSecurityConfigurerAdapter 的類時(shí)，Spring 總是會(huì)拋出org.springframework.security.config.annotation.AlreadyBuiltException: This object has already been builtafter org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'springSecurityFilterChain' defined in class path resource [org/springframework/security/config/annotation/web/configuration/WebSecurityConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.servlet.Filter]: Factory method 'springSecurityFilterChain' threw exception; nested exception is org.springframework.security.config.annotation.AlreadyBuiltException: This object has already been built，我不知道為什么。我嘗試刪除@Configuration注釋，@EnableWebSecurity一個(gè)，兩個(gè)，并添加其他注釋，例如@Order，但添加或刪除注釋似乎沒(méi)有幫助。
