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述，应定义 spring.security.oauth2.client。有我的：

  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：

Caused by: java.lang.IllegalArgumentException: Unable to resolve Configuration with the provided Issuer of "https://myhost/auth/realms/master"

如何在应用启动时禁用证书验证？

请看一下，当您尝试从 restapi 客户端或任何 Web 应用程序连接 keycloak 时，如果您遇到如下错误

原因：org.springframework.web.client.ResourceAccessException：“ https://myhost/auth/realms/master/.well-known/openid-configuration ”的 GET 请求上的 I/O 错误：sun.security.validator。 ValidatorException：PKIX 路径构建失败：sun.security.provider.certpath.SunCertPathBuilderException：无法找到请求目标的有效证书路径；嵌套异常是 javax.net.ssl.SSLHandshakeException：sun.security.validator.ValidatorException：PKIX 路径构建失败：sun.security.provider.certpath.SunCertPathBuilderException：无法找到请求目标的有效证书路径

它试图告诉您证书未添加到 java 密钥库中或错误的证书添加到密钥库中。

正如您https在端点中给出的那样，必须在 Java 密钥库中导入/添加证书。

您必须将证书导入客户端计算机

在客户端机器中导入证书

 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 密钥库的密码changeit
