java - Spring MVC安全: Error creating bean with name 'springSecurityFilterChain'

Question

我正在尝试学习 Spring Security 并查看了一些教程，但我似乎无法运行该应用程序。我拥有所有依赖项和配置类，但它给了我一个错误，我找不到原因

WebSecurityConfig.java:

@EnableWebSecurity

public class WebSecurityConfig implements WebMvcConfigurer {

 @Bean
    public UserDetailsService userDetailsService() throws Exception {
        InMemoryUserDetailsManager manager = new InMemoryUserDetailsManager();
        manager.createUser(User.withDefaultPasswordEncoder().username("user").password("password").roles("USER").build());
        return manager;
    }
}

SecurityWebAppInitializer.java:

public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer {


}

错误:

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.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration$1': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter.setContentNegotationStrategy(org.springframework.web.accept.ContentNegotiationStrategy); nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mvcContentNegotiationManager' defined in class org.springframework.web.servlet.config.annotation.DelegatingWebMvcConfiguration: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.accept.ContentNegotiationManager]: Factory method 'mvcContentNegotiationManager' threw exception; nested exception is java.lang.AbstractMethodError: com.packt.webstore.config.WebSecurityConfig$$EnhancerBySpringCGLIB$$9d7fee63.configureContentNegotiation(Lorg/springframework/web/servlet/config/annotation/ContentNegotiationConfigurer;)V

Answer 1

我从错误工厂方法“mvcContentNegotiationManager”抛出异常中发现了这一点；嵌套异常是 java.lang.AbstractMethodError:

发生 java.lang.AbstractMethodError 是因为抽象方法在实现时被调用，或者可能缺少某些依赖项。

也许你应该将代码更改为

@EnableWebSecurity

public class WebSecurityConfig implements WebSecurityConfigurerAdapter{
}

或

@EnableWebSecurity

public class WebSecurityConfig implements WebMvcConfigurerAdapter{
}
