扩展阔叶默认管理控制器

Question

我想为管理端（broadleaf 框架）创建自己的控制器，它扩展了 AdminBasicEntityController。有我的控制器代码：    public class AdminArticleController extends AdminBasicEntityController {    @Autowired    private ArticleService articleService;    @Override    public String addEntity(HttpServletRequest request, HttpServletResponse response, Model model, @PathVariable Map<String, String> pathVars, @ModelAttribute("entityForm") EntityForm entityForm, BindingResult result) throws Exception {        return super.addEntity(request, response, model, pathVars, entityForm, result);    }    @Override    public String saveEntityJson(HttpServletRequest request, HttpServletResponse response, Model model, @PathVariable Map<String, String> pathVars, @PathVariable("id") String id, @ModelAttribute("entityForm") EntityForm entityForm, BindingResult result, RedirectAttributes ra) throws Exception {        return super.saveEntityJson(request, response, model, pathVars, id, entityForm, result, ra);//        articleService.updateArticleEntity();    }}我还在 AdminServletConfig 文件中添加了下一个代码：@Beanpublic AdminBasicEntityController adminBasicEntityController() {    return new AdminArticleController();}

你很亲近！要覆盖现有的 Broadleaf bean，请务必使用注释中声明的 bean 名称。将您的 bean 命名为“blAdminBasicEntityController”，如下所示：

@Bean

public AdminBasicEntityController blAdminBasicEntityController() {

    return new AdminArticleController();

}

您看到的错误是由于有两个具有相同映射的 bean。发生这种情况是因为 AdminBasicEntityController 带有注释@Controller("blAdminBasicEntityController")，这意味着它将被组件扫描拾取并创建一个名为 的 bean blAdminBasicEntityController。由于 AdminArticleController 扩展了 AdminBasicEntityController，一旦创建了 AdminArticleController bean，AdminBasicEntityController 中的每个映射都会有 2 个映射。解决方案是覆盖 Broadleaf bean，而不是添加一个额外的。
