错误:

• 即使客户端根本没有启动

  http://localhost: 8080/

• 控制台错误:

---

应用程序启动失败

---

描述:

没有定义spring.config.import属性

行动:

添加spring.config。Import =configserver:属性到您的配置。如果不需要配置，添加spring.config。进口=可选:configserver:代替。要禁用此检查，请设置spring.cloud.config。启用= false或spring.cloud.config.import-check.enabled = false .

Answer 1

要使用传统的引导方式连接到Config Server，必须通过属性或spring-cloud-starter-bootstrap启动器启用引导。属性为spring.cloud.bootstrap.enabled=true。它必须设置为系统属性或环境变量。spring文档

Answer 2

在花费了太多时间之后，我找到了两种方法来解决这个问题基本上我们需要让的值spring。cloud。bootstrap。enabled真正为默认为false． 在Spring Cloud文档中已经提到了这一点，但我第一次没有得到这一点。找到此问题的解决方案后，春云文档点已清除。

第一种方法:设置@SpringBootApplication类中的System环境变量

public static void main(String[] args) throws IOException {
System.setProperty("spring.cloud.bootstrap.enabled","true");
run(Application.class, args);
}

第二种方法:作为pom.xml中的依赖项，它使spring.cloud.bootstrap.enabled
