高分求解Spring配置问题，在线等解答！
公司的项目需要重构---把原来的XML里边的bean配置全都换成注入注解，现在报以下错误:

Does the parameter type of the setter match the return type of the getter?

关于CountryServiceImpl和RegionServiceImpl，出现了循环引用：
@Service("countryService")
public class CountryServiceImpl extends BaseService<Country> implements CountryService {
@Autowired
private RegionService regionService;
@Autowired
private AreaService areaService;
/**
* @param regionService the regionService to set
*/
public void setRegionService(RegionService regionService) {
this.regionService = regionService;
}
/**
* @param areaService the areaService to set
*/
public void setAreaService(AreaService areaService) {
this.areaService = areaService;
}
@Service("regionService")
public class RegionServiceImpl extends BaseService<Region> implements RegionService {
@Autowired
private CountryService countryService;
/**
* @param countryService the countryService to set
*/
public void setCountryService(CountryService countryService) {
this.countryService = countryService;
}
