@Outowire在球衣資源類中給出空指針異常

Question

我正在嘗試@autowire我的球衣資源類與我的映射器接口，它給予空指針註釋異常，但@autowire在我的調度器控制器中正常工作。我是新來的春天MVC，我只想要一個方法來@autowire我的球衣資源類與我的映射器界面。

控制器代碼

@Controller 
public class EmployController { 
    @Autowired 
    EmployMapper employMapper; 

    @RequestMapping("test") 
    public ModelAndView reviewspage() 
    { 
     employMapper.updateMytable("SpringController"); 
      ModelAndView modelAndView = new ModelAndView("test"); 
      return modelAndView; 
    } 
} 

球衣資源類

@Path("/employees") 
@Repository 
public class MyResource { 
    @Autowired 
    EmployMapper employMapper; 

    @GET 
    @Produces(MediaType.TEXT_PLAIN) 
    public String getEmployees(){ 
     employMapper.updateMytable("WebAPiController"); 
     return "Successfuly done"; 
    } 
} 

映射器接口

public interface EmployMapper { 
    public int finduser(@Param("MName") String MName,@Param("password") String password); 
    public int updateMytable(@Param("name") String name); 
}

我的猜測是，你還沒有配置新澤西委託對象生命週期去春來，使用jersey-spring。如果沒有明確地完成，Jersey本身將控制生命週期，這意味着Jersey將實例化你的資源類。
