我对微型服务很陌生，在那里我必须使用两个服务(这是我在不同的项目中做的)。现在我正在尝试在我的application.yml文件中设置Eureka配置。

但是，从上面的截图中可以看到，它正在抛出错误：

Nested mappings are not allowed in compact mapping

和

Multiple markers at this line:
- Nested mappings are not allowed in compact mapping
- Implicit keys need to be on a single line

另外，我试过

我在下面分享我的EServerApplication.java代码：

package com.eserver;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class EServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(EServerApplication.class, args);
    }

}

下面是我的pom.xml文件内容：

<?xml version="1.0" encoding="UTF-8"?>

</project>

但是，当我在application.properties文件中配置相同的东西时，它工作得很好。

请指导我如何才能修正application.yml错误。

编辑:已解决的

我发现这个yml配置文件对每个组件的空白很敏感，因此我在我的程序中更正了它。快把线关了！

yaml文件遵循不同的命名约定。下列属性应解决您的问题。

eureka:
  client:
    register-with-eureka: false
    fetch-registry: false
  server:
    wait-time-in-ms-when-sync-empty: 0
