我已经创建了spring boot web应用程序,但我无法在tomcat上部署spring boot web应用程序WAR文件,我可以将其作为java应用程序运行.如何在tomcat上将spring boot应用程序作为Web服务运行.我正在使用以下代码.如果可以在tomcat上运行,请在不使用web.xml和使用web.xml的情况下帮助我使用注释.

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
       return application.sources(Application.class);
    }

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

}

以下代码为休息控制器

@RestController
public class HelloWorld{

   @RequestMapping(value = "/hello", method = RequestMethod.GET)
   public ResponseEntity<String> get() {
       return new ResponseEntity<String>("Hello World", HttpStatus.OK);
   }
}

我正在使用Pom.xml

<groupId>org.springframework</groupId>
<artifactId>web-service</artifactId>
<version>0.1.0</version>

    <groupId>org.springframework.boot</groupId>

我需要从源表创建一个表（hive 表/spark 数据框），该表将多行用户的数据存储到单行列表中。

User table:
Schema:  userid: string | transactiondate:string | charges: string |events:array<struct<name:string,value:string>> 
----|------------|-------| ---------------------------------------
123 | 2017-09-01 | 20.00 | [{"name":"chargeperiod","value":"this"}]
123 | 2017-09-01 | 30.00 | [{"name":"chargeperiod","value":"last"}]
123 | 2017-09-01 | 20.00 | [{"name":"chargeperiod","value":"recent"}]
123 | 2017-09-01 | 30.00 | [{"name":"chargeperiod","value":"0"}]
456 | 2017-09-01 | 20.00 | [{"name":"chargeperiod","value":"this"}]
456 | 2017-09-01 | 30.00 | [{"name":"chargeperiod","value":"last"}]
456 | 2017-09-01 | 20.00 | [{"name":"chargeperiod","value":"recent"}]
456 | 2017-09-01 | 30.00 | [{"name":"chargeperiod","value":"0"}]

输出表应该是

userid:String | concatenatedlist :List[Row]

123    | …
