Question

我的方法在逻辑上应该在不同控制器的基本控制器类（上传图标）中。这不是特定控制器的功能。这是代码：

public abstract class BaseTabsManagementController{
    ...
    @RequestMapping(method = RequestMethod.POST, value = "/upload_tab_icon")
    public @ResponseBody Response<List<Icon>> saveIcon(@RequestParam("tabIcon") MultipartFile file,
            @ModelAttribute(TAB_BEAN) AddEditTabBean tabBean) {
        ...
    }
}

我有2个派生控制器AddEditTabController和AddEditContentPageController。但是当我运行代码时，我得到了以下异常

    org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping#0': Initialization of bean failed; nested exception is java.lang.IllegalStateException: Cannot map handler 'addEditTabController' to URL path [/admin/ui/upload_tab_icon]: There is already handler of type [class com.synisys.idm.analytics.designer.controller.AddEditContentPageController] mapped.

        at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:456)
.......

有人知道如何解决这个问题吗？
