spring-saml多租户环境中的端点验证方法

问题描述

我正在构建多租户环境。 您需要能够访问https://tenant1.com或https://tenant2.com上的一个应用。

事实证明，要为每个URL指定SP元数据，可以通过给元数据一个别名来指定它。 但是，端点验证也需要相应。

在samlContextProviderLB的ServerName中设置了

tenant1.com。在这种状态下 使用https://tenant2.com访问时，发生以下错误。

SAML消息预期的目标端点“ https://tenant2.com/xxx” 与收件人终结点“ https://tenant1.com/xxx”不匹配

以下是一些securityConfig设置。

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

    @Autowired
    private SecurityProperties securityProperties;

        samlContextProviderLB.setServerPort(443);
        samlContextProviderLB.setIncludeServerPortInRequestURL(false);
        samlContextProviderLB.setcontextpath("");
        EmptyStorageFactory emptyStorageFactory = new EmptyStorageFactory();
        samlContextProviderLB.setStorageFactory(emptyStorageFactory);
        return samlContextProviderLB;

            http.csrf().disable();

}

作为解决问题的方法，

在samlContextProviderLB中设置多个serverNames

或

请勿执行端点验证

可以考虑。 但是，我不知道具体的实现方法。 救救我！
