使用Ext JS Ajax调用的Spring MVC 406响应

Question

我目前正在研究一个简单的应用程序，该应用程序从MySQL数据库获取用户列表并将数据作为JSON格式返回。我正在使用Ext JS Store进行ajax调用。

商店：

Ext.define('MyApp.store.AdminUsers', { 
    extend: 'MyApp.store.BaseStore' 
    ,model: 'MyApp.model.AdminUser' 
    ,remoteSort: true 
    ,pageSize: 20 
    ,proxy: { 
     type: 'ajax' 
     ,url: contextPath + '/admin/users/list.htm' 
     ,actionMethods: 'POST' 
     ,simpleSortMode: true 
     ,pageParam: undefined 
     ,reader: { 
      type: 'json' 
      ,root: 'adminUsers' 
      ,successProperty: 'success' 
      ,totalProperty: 'totalCount' 
     } 
    } 
}); 

Spring MVC的控制器：

@Controller 
@RequestMapping("/admin/users/") 
public class AdminUserController extends BaseController { 
// items removed for brevity 
@RequestMapping(value = "/list") 
@ResponseBody 
public Model listAllAdminUsers(Model model, HttpServletRequest request) throws Exception { 
    FindInfo findInfo = getFindInfo(request); 
    model.addAttribute("totalCount", adminUserService.getCount(findInfo)); 
    model.addAttribute("adminUsers", AdminUserConverter.createListData(adminUserService.getList(findInfo))); 
     return model; 
    } 
} 

的web.xml：

<listener> 
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
</listener> 

<listener> 
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>

我有我的类路径正确杰克逊库，有时我得到406错误，尝试在Ext JS中更改接受和内容类型标题，并为listAllAdminUsers方法定义produces类型。当我得到一个404（我尝试了几种不同的东西）时，spring试图将控制器方法解析为视图，并且正在寻找admin/users/list.jsp（不知道为什么？）。我已经用尽了所有的选项，搜索了很多答案，并且我尝试了一切似乎。请帮忙！！

Answer 1

所有我不得不改变是把@ResponseBody到收益模型，而不是方法本身。

Answer 2

你有两个问题： 1.第一个是关于Accept头。您提到的问题已解决。 2.关于URL映射，在你的要求，你发送一个请求/admin/users/list.htm但你的控制器不仅响应请求/管理/用户/列表所做

试试这个

Ext.define('MyApp.store.AdminUsers', { 
    extend: 'MyApp.store.BaseStore' 
    ,model: 'MyApp.model.AdminUser' 
    ,remoteSort: true 
    ,pageSize: 20 
    ,proxy: { 
     type: 'ajax' 
     ,url: contextPath + '/admin/users/list' 
     ,actionMethods: 'POST' 
     ,simpleSortMode: true 
     ,pageParam: undefined 
     ,reader: { 
      type: 'json' 
      ,root: 'adminUsers' 
      ,successProperty: 'success' 
      ,totalProperty: 'totalCount' 
     } 
    } 
});
