我正在研究其中一个教程（https://developer.okta.com/blog/2018/09/26/build-a-spring-boot-webapp）。它可以按预期工作，但当我在防火墙后面工作时除外。每当我运行./gradlew bootRun命令时，它都会给出错误：org.springframework.web.client.ResourceAccessException: I/O error on GET request for "http://dev-446070.okta.com/oauth2/default/v1/authorize/.well-known/openid-configuration": Operation timed out (Connection timed out);。
我尝试在gradle-wrapper.properties文件中设置代理设置，但这似乎无济于事。关于在哪里可以输入代理设置以使其正常工作的任何想法。
这是完整的输出：
