需要從Spring MVC的控制器

我的工作在Spring MVC和Jsoup和寫的春天控制器，發送這是從下面的代碼獲得的Jsoup Connection.Response返回JSoup Conncetion.Response爲響應：需要從Spring MVC的控制器

@RequestMapping(method = RequestMethod.POST, value = "/getPage") 
public Connection.Response getJsoupResponsePage(Principal loggedInUser, 
           HttpServletRequest request,HttpServletResponse response) { 

Connection.Response res = Jsoup.connect(url) 
           .data("j_username", "username") 
           .data("j_password", "password") 
           .method(Method.POST).execute(); 
return res; 
}

我需要完整的Connection.Response對象才能在瀏覽器的新選項卡中打開。

我從瀏覽器調用jquery ajax請求，url是不同的域名，所以我已經打開該網址的會話，然後發送請求到/getPage。

var ajax_params; 
ajax_params = { 
      url : "getPage", 
      type : "POST", 
      cache : false, 

      success : function(response) { 
       console.log(response); 
      }, error : function() { 
       console.log("ERROR"); 
      } 
    } 
$.ajax(ajax_params);

我得到406不能接受的，我在Ajax調用收到錯誤。

的pom.xml提前

所以你想在你的迴應中發送一個Java對象，讓客戶端以某種方式使用它？也許你想從這個Connection.Response實例發送（String）內容？ –

用spring和你的pom.xml版本更新你的問題 –

我使用Spring 4.1.6.RELEASE和Jsoup 1.8.1 – Yogeendra

406 http狀態碼是not acceptable。這意味着你的情況下彈簧不能Could not find acceptable representation爲你的Connection.Response對象。將其更改爲String並返回JSOUP響應的主體。

@RequestMapping(method = RequestMethod.POST, value = "/page") 
public @ResponseBody String getJsoupResponsePage(HttpServletRequest request,HttpServletResponse response) throws IOException { 

    Connection.Response res = Jsoup.connect("http://abv.bg") 
      .data("j_username", "username") 
      .data("j_password", "password") 
      .method(Connection.Method.POST).execute(); 
    return res.body(); 
}

，並用此方法AJAX調用它：

var ajax_params = { 
      url : "page", 
      type : "POST", 
      cache : false, 
      success : function(response) { 
       console.log(response); 
      }, error : function() { 
       console.log("ERROR"); 
      } 
    } 
$.ajax(ajax_params);

PS：我有點有點納悶你正在嘗試做的。只是解決了406錯誤。
