把@SpringBootApplication改成 @SpringBootApplication(exclude={DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
即：

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})

//@SpringBootApplication
public class CloudApplication {

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

}

即可运行成功。
