Spring-boot how to use autowired class properties in called method -

i have following class in spring-boot application

public class classa {      @autowired     propertiesclass propertiesclass;      public integer getmesomevalue(integer someparameter) {         // uses methods of propertiesclass     }  } 

here, propertiesclass contains methods reads property values application.properties file. want unit test getmesomevalue method. unit test class given below

@runwith(springjunit4classrunner.class) @springapplicationconfiguration(myapplication.class) @webintegrationtest public class classatest {      @test     public void testgetmesomevalue() {         classa classa = new classa();         assert.assertsame("received expected response", classa.getmesomevalue(6025), 2345);     } } 

when run unit test, null pointer exception @ point methods of propertiesclass invoked inside getmesomevalue method. there way in spring-boot make @autowired work?

instead of

classa classa = new classa(); 

do this...

@autowired classa classa; 

so classa bean available within spring container.
