春季启动内置tomcat服务器不启动

Question

我正在使用inbuild tomcat服务器构建一个非常基本的spring-boot服务。

双响炮看起来是这样的：

<groupId>com.example</groupId> 
<artifactId>demo</artifactId> 
<version>0.0.1-SNAPSHOT</version> 
<packaging>jar</packaging> 
<name>demo</name> 
<description>Demo project for Spring Boot</description> 
<parent> 
    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-starter-parent</artifactId> 
    <version>1.5.7.RELEASE</version> 
    <relativePath/> <!-- lookup parent from repository --> 
</parent> 
<properties> 
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 
    <project.reporting.outputEncoding>UTF8</project.reporting.outputEncoding> 
    <java.version>1.8</java.version> 
</properties>

</dependencies> 

<build> 
    <plugins> 
     <!--<plugin> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-maven-plugin</artifactId> 
     </plugin>--> 


      <plugin> 
       <groupId>org.apache.maven.plugins</groupId> 
       <artifactId>maven-compiler-plugin</artifactId> 
       <version>3.3</version> 
       <configuration> 
        <source>1.8</source> 
        <target>1.8</target> 
       </configuration> 
      </plugin> 
    </plugins> 
</build> 

我在application.properties文件server.port=8089设置端口。有一个平URI在控制器类添加为：

@RequestMapping("/ping") 
@RestController 
public class helloController { 

    @RequestMapping(method= RequestMethod.GET,produces = {MediaType.APPLICATION_JSON_VALUE}) 
    public ResponseEntity<String> ping(){ 
     return new ResponseEntity<>("Hello World Spring-boot app", HttpStatus.OK); 
    } 

当我做了mvn clean package一切正常，并构建是成功的。但是，当我从Main()运行应用程序，这是什么日志的样子：

2017-09-19 10:37:32.219 INFO 6436 --- [   main] com.example.demo.DemoApplication   : No active profile set, falling back to default profiles: default

日志没有显示什么端口的服务正在启动。

还有什么要做，以启动指定端口上的服务，并保持服务器运行？
