Calling service layer directly from main class - spring

Question

I have a project structure controller -> response builder -> service layer.
Here service layer call the repository layer(database layer).
Everything is ok when follow the structure.
But,for testing i want to call the service layer directly from a java main class.
How can i do this??????
My controller:
#RestController
#RequestMapping("/ishmam")
public class IshmamAddressController {
#Autowired
#Qualifier("ishmamAddressBuilder")
IshmamAddressBuilder ishmamAddressBuilder;
#RequestMapping("/getAddress")
public IResponseDto<WebbCustomerAddressDto> getAllAddress(){
return ishmamAddressBuilder.getAllAddress();
}
}
My builder class is:
#Component("ishmamAddressBuilder")
public class IshmamAddressBuilder {
#Autowired
#Qualifier("ishmamAddressServiceImpl")
IshmamAddressInterface ishmamAddressService;
public IResponseDto<IshmamAddressResponseDto> getAllAddress(){
IResponseDto<WebbCustomerAddressDto> response=new
IResponseDto<WebbCustomerAddressDto>();
try{
//here i call the service layer
List<String> addressList=ishmamAddressService.getAllAddress();
}catch(Exception e){
throw e;
}
return addressList;
}
My service layer is:
#Service("ishmamAddressServiceImpl")
#Transactional
public class IshmamAddressServiceImpl implements IshmamAddressInterface {
#Autowired(required = true)
#Qualifier("webCustomerAddressRepository")
WebCustomerAddressRepository webCustomerAddressRepository;
#Override
public IshmamAddressResponseDto getAllAddress() {
List<WebCustomerAddress> aList = new ArrayList<WebCustomerAddress>();
List<WebbCustomerAddressDto> dtoWebCustomerAddressList = new
ArrayList<WebbCustomerAddressDto>();
IshmamAddressResponseDto ishmamAddressResponseDto=new
IshmamAddressResponseDto();
try{
aList =
address.getAllAddress(1);//Calling database layer
ishmamAddressResponseDto=//Doing something,not important for
//question
}
return ishmamAddressResponseDto;
}
Now what i want is to call the service layer directly from the main class:
public class Address{
public void getAddress(){
IshmamAddressServiceImpl i=new IshmamAddressServiceImpl();
List<String> list=i.getAllAddress();
}
public static void main(String[] args){
Address a=new Address();
a.getAddress();
}
}
This process is not working.How can i do this???????

As soon as you use spring, you must never use new to build an object that should be managed by spring.
So you could:
either do it manually, that means bootstrap an application context with the same intialization that it would have in your application and explicitely get a bean from it
ApplicationContext ctx = new AnnotationConfigApplicationContext(
Class<?>... annotatedClasses); // if it is the way you use it ...
IshmamAddressInterface i = ctx.getBean("ishmamAddressServiceImpl",
IshmamAddressInterface .class);
or use the Spring test framework that does it automatically for you in Junit tests
#WebAppConfiguration
#ContextConfiguration(classes = ...)
public class WebIntegrationTests {
#Autowired
#Qualifier("ishmamAddressServiceImpl")
IshmamAddressInterface ishmamAddressService;
...
#Test
public void testGetAddress() {
ishmamAddressService.getAddress();
...
}
}
