我正在尝试使用Spring Boot编写一个简单的RESTful服务。但是，有一条错误消息我无法解决。我一直在研究，看来这是SpringBoot版本之间的冲突，但是我不确定如何摆脱它。

我有这个SpringBootApp：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * REST Service application
 */
@SpringBootApplication
public class Application {

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

与此pom.xml相关联：

对我来说看起来不错，但出现此错误：
