auth2 如果配置gateway进行访问

如果您使用 Spring Cloud Gateway 来配置 OAuth2 授权和资源服务器，则需要进行以下步骤：

1. 在 Gateway 的 pom.xml 文件中添加以下依赖：

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-gateway</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-security</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-oauth2-resource-server</artifactId>
</dependency>

2. 在 application.yml 或 application.properties 文件中配置 OAuth2 客户端和资源服务器信息，例如：

spring:
  security:
    oauth2:
      client:
        registration:
          your-client-registration-id:
            client-id: your-client-id
            client-secret: your-client-secret
            scope: your-scope
            authorization-grant-type: authorization_code
            redirect-uri-template: your-redirect-uri-template
            client-name: your-client-name
        provider:
          your-provider-name:
            authorization-uri: your-authorization-uri
            token-uri: your-token-uri
            user-info-uri: your-user-info-uri
            user-name-attribute: your-user-name-attribute
      resourceserver:
        jwt:
          issuer-uri: your-issuer-uri
          jwk-set-uri: your-jwk-set-uri

3. 在 Gateway 配置类中添加 OAuth2 鉴权过滤器，例如：

@Configuration
public class GatewayConfig {
    @Bean
    public SecurityWebFilterChain securityWebFilterChain(ServerHttpSecurity http) {
        http
                .authorizeExchange()
                .pathMatchers("/oauth2/callback").permitAll()
                .anyExchange().authenticated()
                .and()
                .oauth2Login()
                .and()
                .oauth2ResourceServer()
                .jwt();
        return http.build();
    }
}

这样，您就可以使用 Spring Cloud Gateway 配置 OAuth2 认证和资源服务器了。
