Autowired not working, dependency is null - spring

Question

The project that I have is currently set up like so:
Controller:
package com.frclocks.district.controller;
:imports:
#Path("/districts")
#Controller
public class DistrictController {
#Autowired
private DistrictService districtService;
#GET
#Produces(MediaType.APPLICATION_JSON)
public List<District> getDistricts() {
return districtService.getAllDistricts();
}
}
Service (Impl):
package com.frclocks.district.service;
:imports:
#Service("districtService")
#Transactional
public class DistrictServiceImpl implements DistrictService {
#Autowired
private DistrictDao districtDao;
#Override
public List<District> getAllDistricts() {
return districtDao.getAllDistricts();
}
}
Config:
package com.frclocks.config;
:imports:
#Configuration
#ComponentScan(basePackages="com.frclocks", includeFilters=#ComponentScan.Filter(Controller.class))
public class AppConfig { }
The web.xml is empty as I'll be using JavaConfig instead of xml, nor do I have any spring config xml. I have read through several tutorials online, several threads on here, and even browsed through a project at work that I'm developing with which also uses #Autowired and have reached a brick wall. Some of the tutorials say to do something in a main class (such as here: Spring Docs) but the project at work doesn't do anything like that. It has a similar AppConfig (with a few additional, not necessary annotations for me) and no xml config files. What would I be doing wrong? What am I missing here? Thanks!

You have mixed RestEasy and Spring MVC. You should decide for either of those frameworks for your REST endpoints. #Controller is a Spring annotation, while #Path is a JAX-RS annotation. Both together don't work. Currently your Controller is called through RestEasy, which doesn't know anything about your Spring configuration.
