Spring boot applicaton will not stay up - spring

Question

I created a simple REST Spring boot application. I see it start, but it immediately shutsdown. There is no error in log.
Below is the code and the log.
Code:
#Controller
#ComponentScan
#EnableAutoConfiguration
#RequestMapping("userInfo")
public class UserUpdateService
{
private java.util.logging.Logger logger = Logger.getLogger("UserUpdateService");
#RequestMapping(value="/{userId}", method=RequestMethod.GET, produces = "application/xml; charset=utf-8")
#ResponseBody
String getUserInfo(#PathVariable String userId)
{
String func = "getUserInfo";
logger.entering("UserUpdateService", func);
String retval = "";
return retval;
}
#RequestMapping(value="/{userId}", method=RequestMethod.DELETE, produces = "application/xml; charset=utf-8")
#ResponseBody
String removeUser(#PathVariable String userId)
{
String retval = "";
String func = "removeUser";
logger.entering("UserUpdateService", func);
return retval;
}
#RequestMapping(value="/", method=RequestMethod.PUT, produces = "application/xml; charset=utf-8")
#ResponseBody
String addUser(#WebParam (name = "userId")String userId)
{
String retval = "";
String func = "addUser";
logger.entering("UserUpdateService", func);
return retval;
}
public static void main(String[] args)
{
ApplicationContext ctx = SpringApplication.run(UserUpdateService.class, args);
}
}
Log:
Java HotSpot(TM) Server VM warning: .hotspot_compiler file is present but has been ignored. Run with -XX:CompileCommandFile=.hotspot_compiler to load the file.

Answer 1

if you are using maven, check out your pom.xml file, then you will find something like this:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
it should be changed to this instead:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
