spring-security - spring security oauth2 客户端提供程序颁发​​者-uri 上的自签名证书

Question

我正在尝试创建一个可以访问 Keycloak 安全休息服务的 Spring Boot 客户端应用程序示例。

正如几乎所有教程中所描述的，应该定义 spring.security.oauth2.client 。 这是我的:

  security:
    oauth2:
      client:
        registration:
          keycloak:
            client-id: my-id
            client-secret: my-secret
            authorization-grant-type: client_credentials
        provider:
          keycloak:
            issuer-uri: https://myhost/auth/realms/master

但是我在 myhost Keycloak 测试服务器下有自签名证书，所以当应用程序启动时我得到这个:

如何在应用程序启动时禁用证书验证？

当尝试从restapi客户端或任何Web应用程序连接keycloak时，请查看是否遇到如下错误

Caused by: org.springframework.web.client.ResourceAccessException: I/O error on GET request for "https://myhost/auth/realms/master/.well-known/openid-configuration": sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target; nested exception is javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

它试图告诉您证书未添加到 java keystore 中或添加到 keystore 中的证书错误。

由于您在终点中给出了 https，因此必须在 Java keystore 中导入/添加证书。

您必须将证书导入客户端计算机

在客户端计算机中导入证书

 keytool -import -noprompt -trustcacerts -alias "initcert" -file keycloak.cer -keystore "C:\Program Files\Java\jdk1.8.0_152\jre\lib\security\cacerts"

默认情况下 Java keystore 的密码 changeit
