弹簧靴1.3.5无法启动？

Question

我正在使用弹簧靴1.3.5和弹簧4.2.6，并且不确定弹簧靴是否正在运行。日志中没有错误，即使尝试也无法看到spring boot横幅：

SpringApplication app = new SpringApplication(App.class);
app.setBannerMode(Banner.Mode.LOG);
app.run(args);

或

app.setBannerMode(Banner.Mode.CONSOLE);

此外，我无法从application.yml中读取配置文件属性

这让我想知道springboot是否真的在运行。有没有办法确认？

application.yml：     弹簧：       个人资料：         主动：“ dev”

spring:
  profiles: dev

  cluster:
    - ip: 127.0.0.1

ServerProperties.java

 @Component
    @ConfigurationProperties("server")
    public class ServerProperties {

     private List<Cluster> cluster = new ArrayList<>();

        public static class Cluster {
            private String ip;
            private String path;

            public String getIp() {
                return ip;
            }

            public void setIp(String ip) {
                this.ip = ip;
            }

            public String getPath() {
                return path;
            }

            public void setPath(String path) {
                this.path = path;
            }

            @Override
            public String toString() {
                return "Cluster{" +
                        "ip='" + ip + '\'' +
                        ", path='" + path + '\'' +
                        '}';
            }
        }



        public List<Cluster> getCluster() {
            return cluster;
        }

        public void setCluster(List<Cluster> cluster) {
            this.cluster = cluster;
        }

        @Override
        public String toString() {
            return "ServerProperties{" +
                    "cluster=" + cluster +
                    '}';


  }
}
