Spring boot maven management-HelloWorld

After the configuration file is configured, you can write the first example!

@ Controller
@ EnableAutoConfiguration ()
Public class SampleController
{
Private Hello;


@ Autowired
Public SampleController (Hello hello)
{
This. hello = hello;
}


@ RequestMapping ("/")
@ ResponseBody
String home (String type)
{
System. out. println ("login:" + hello );
Return "Hello World ";
}


Public static void main (String [] args) throws Exception
{
SpringApplication app = new SpringApplication (SampleController. class );
App. setWebEnvironment (true );
App. setShowBanner (false );

SetSet = new HashSet();
Set. add ("classpath: applicationContext. xml ");
App. setSources (set );
App. run (args );
}
}

Right-click the java application and enter: localhost: 8080/in the browser/

SetSet = new HashSet();
Set. add ("classpath: applicationContext. xml ");
