Tomcat 不会从具有自签名证书的服务器下载文件

Question

我有一个（远程）tomcat 服务器 (idp.mydomain.com)，我在其中部署了 Shibboleth IDP。使用自签名证书通过 SSL 保护通信。如果我向浏览器添加例外，我可以访问元数据配置 XML。

第二次（本地）tomcat (sp.localhost.mydomain.com) 我有一个 spring 应用程序，它使用 SAML 对我的 IDP 进行身份验证。但是，启动 SP 时出现以下证书错误：

如果我反对具有有效证书的服务器，它会起作用，但我如何才能说服我固执的 tomcat 也接受自签名证书？

Answer 1

您需要创建 JKS 信任库并包含 self-signed 证书的 public 部分。然后，SSL 连接将接受服务器证书

从

开始 tomcat

-Djavax.net.ssl.trustStore=/path/to/truststore.jks 
-Djavax.net.ssl.trustStorePassword=truststorePassword

见add jvm options in tomcat

Tomcat 不会从具有自签名证书的服务器下载文件

Tomcat will not download file from a server with self-signed certificate

tomcat

ssl

self-signed
