面临错误 securityFilterChain 方法的参数 0 需要类型为“org.springframework.security”的 bean。找不到那个

Question

我正在使用 Spring Boot 微服务（Spring Boot 版本-3）。我正在使用oauth2。当我在安全配置文件上使用安全性时，我遇到错误。它在网关服务器上。

我的 Pom 文件是：

我的安全配置文件是：

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.reactive.EnableWebFluxSecurity;
import org.springframework.security.web.SecurityFilterChain;


@Configuration
public class SecurityConfig {

    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {

        http.oauth2ResourceServer(
                c -> c.jwt(
                        j -> j.jwkSetUri("http://localhost:8080/oauth2/jwks")
                )
        );

        http.authorizeHttpRequests(auth -> {
            auth.requestMatchers("/user/auth").permitAll()
                    .requestMatchers("/**").authenticated();
        });

        return http.build();
    }
}

我的错误是： 上下文初始化期间遇到异常 - 取消刷新尝试：org.springframework.beans.factory.UnsatisfiedDependencyException：创建类路径资源 [com/tnpay/gatewayservice/config/SecurityConfig.class] 中定义的名为“securityFilterChain”的 bean 时出错：表达了不满足的依赖关系通过方法“securityFilterChain”参数0：没有可用的“org.springframework.security.config.annotation.web.builders.HttpSecurity”类型的合格bean：预计至少有1个符合自动装配候选资格的bean。依赖注释：{}

com.tnpay.gatewayservice.config.SecurityConfig 中的 securityFilterChain 方法的参数 0 需要一个类型为“org.springframework.security.config.annotation.web.builders.HttpSecurity”的 bean，但无法找到。

行动：

考虑在配置中定义“org.springframework.security.config.annotation.web.builders.HttpSecurity”类型的 bean。

我想解决这个问题。

Answer 1

在您的

@EnableWebSecurity

班级级别添加

SecurityConfig

注释，这是必需的，因为：

@EnableWebSecurity

是标记注释。它允许 Spring 找到（它是一个

@Configuration

，因此是

@Component

）并自动将该类应用到全局 WebSecurity。

你会得到这样的东西：

@Configuration
@EnableWebSecurity
public class SecurityConfig {...}
