Spring项目中控制器和服务类的通用类

时间：2014-05-28 11:13:34

标签： java spring spring-mvc generics

我正在尝试为我的所有控制器和服务类使用的商店常用方法添加泛型类，到目前为止我得到了这段代码：

控制器

https://github.com/klebermo/blog.cms/blob/master/src/main/java/com/config/generic/controller/controller.java

服务

https://github.com/klebermo/blog.cms/blob/master/src/main/java/com/config/generic/service/service.java

我的目标是能够实现我的所有控制器和服务类：

控制器 

@Controller
@RequestMapping(value="usuario")
public class UsuarioController extends controller<Usuario> {

    public UsuarioController() {
        super(Usuario.class);
    }

}

服务 

@Service
public class UsuarioService extends service<Usuario> {

    public UsuarioService() {
        super(Usuario.class);
    }

}

但是现在，我收到了这个错误：

任何人都知道如何解决这个问题？

ps。：我无法确定应将哪个参数传递给注释ModelAtribute和PreAuthorize，如本主题中所述：

Atribute for annotations @ModelAtribute and @PreAutorize in Generic Controller / Service classes

2 个答案:

答案 0 :(得分：1)

您需要从@Controller移除controller，从@Service移除service。

您不希望Spring管理这些类。他们的后代是将被管理的后代

答案 1 :(得分：0)

愿你的解决方案

@Controller
@RequestMapping(value="usuario")
public class UsuarioController extends controller<Usuario> {

    public UsuarioController( Usuario usuario) {
        super(usuario.class);
    }

}
