我尝试使用我的mapper接口@autowire我的jersey资源类,并且它给出了空指针注释异常但是@autowire在我的调度程序控制器中工作正常。我是spring mvc的新手,我只想通过我的mapper界面找到@autowire我的jersey资源类。
控制器代码
@Controller
public class EmployController {
@Autowired
EmployMapper employMapper;
@RequestMapping("test")
public ModelAndView reviewspage()
{
employMapper.updateMytable("SpringController");
ModelAndView modelAndView = new ModelAndView("test");
return modelAndView;
}
}
球衣资源类
@Path("/employees")
@Repository
public class MyResource {
@Autowired
EmployMapper employMapper;
@GET
@Produces(MediaType.TEXT_PLAIN)
public String getEmployees(){
employMapper.updateMytable("WebAPiController");
return "Successfuly done";
}
}
Mapper界面
public interface EmployMapper {
public int finduser(@Param("MName") String MName,@Param("password") String password);
public int updateMytable(@Param("name") String name);
}
Spring调度程序xml

我的猜测是你没有使用jersey-spring配置Jersey将对象生命周期委托给Spring。如果没有明确地完成,那么Jersey本身将控制生命周期,这意味着它将是Jersey实例化你的资源类。
