JFinal如何配置springPlug?报错

这是service中的代码：

@Service
public class Tuserinfoservice {
 @BY_NAME
 private Tuserinfo tuserinfo;
 public Tuserinfo findbyid(String username){
  return  tuserinfo.findbyid(username);
 }}

这是controller中注解部分的代码：

public class HelloController extends Controller {
 
 @BY_NAME
 private Tuserinfoservice tuserinfoservice;}

这是实体类中的注解部分的代码：

@Repository
public class Tuserinfo extends Model<Tuserinfo> {
 public static final Tuserinfo tuserinfo=new Tuserinfo();}

这是spring的配置文件：

 <!-- bean扫描路径，如果有多个可使用“,”、“;”分隔  -->

</beans>

项目，用new获取的service可以正常获取数据，可以用注解的service就报错：service空指针。请问这样写哪里错了啊
