只是试图从资源恢复教程数据库：http : //www.postgresqltutorial.com/load-postgresql-sample-database/

所以，在这段代码之后

pg_restore -U postgres -d dvdrental /Users/fedotarte/Downloads/dvdrental.zip

我收到当前消息：

pg_restore: [archiver] 输入文件似乎不是有效的存档

我应该怎么做才能成功恢复数据库？

先感谢您！

org.springframework.security.extensions.saml2.config.SAMLConfigurer 不存在

至少我不能在我的安全配置类中导入org.springframework.security.extensions.saml2.config.SAMLConfigurer方法saml()尚未定义。

SecurityConfiguration.java的源代码：

    import com.hem.properties.ServerSsl;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.beans.factory.annotation.Value;

 import org.springframework.security.extensions.saml2.config.SAMLConfigurer;

    @EnableWebSecurity
    @Configuration
    @EnableGlobalMethodSecurity(securedEnabled = true)
    public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

        private static final String HTTPS = "https";

        @Value("${security.saml2.metadata-url}")
        private String metadataUrl;

        @Value("${saml.entity.id}")
        private String entityId;

        @Autowired
        private ServerProxy serverProxy;

        @Autowired
        private ServerSsl serverSsl;

        @Autowired
        private SAMLUserDetailsServiceImpl samlUserDetailsServiceImpl;

        @Override
        protected void configure(final HttpSecurity http) throws Exception {
