Spring MVC：415（Unsupported Media Type）錯誤

Question

這是一個反覆出現的問題，我找到了幾個解決方案。但是沒有一個適合我。
嘗試使用jQuery AJAX發佈表單。

注：我昨天發佈了它，認爲這是客戶端問題。嘗試 客戶端的一切可能，但沒有運氣。

春季控制器

@RequestMapping(value="/save",method=RequestMethod.POST,consumes="application/json") 
    @ResponseBody public String handleSave(@RequestBody String formData) 
    { 


     System.out.println(formData); 
} 

jQuery的請求（嘗試一切什麼人的意見建議）

，如果我送data:$(this).serialize()和contentType:application/json

$('form').submit(function() { 
        $.ajax({ 
         url: $(this).attr('action'), 
         type: 'POST', 
         data: collectFormData(), 
         headers: { 
          "Content-Type":"text/xml" 
         }, 
         dataType: 'xml;charset=utf-8', 
         success: function (data) { 
          alert('data:'+data) 
         }, 
         error: function (jqXHR, textStatus, errorThrown) { 
          alert('jqXHR:'+jqXHR+'\n'+'textStatus:'+'\n'+textStatus+'errorThrown:'+errorThrown); 
         } 
        }); 

        return false; 
       }); 

它工作正常

collectFormData（）

function collectFormData() 
      { 
       $rootElement = $.createElement($('form').attr('name')); 
       $('form').find('div.section').each(function(index, section) { 
        var $sectionElement = $.createElement($(section).attr('name')); 
        console.log('Section Name is:'+$sectionElement); 
        $(section).find('input').each(function(i, field) { 
         var $fieldName = $.createElement($(field).attr('name')); 
         $fieldName.text($(field).val()); 
         $sectionElement.append($fieldName); 
        }); 
        $rootElement.append($sectionElement); 
       }); 
       console.log('Form XML is '+$rootElement.html()); 
       return $rootElement.html();     
      }

Answer 1

我覺得charset應該contentType而不是dataType定義，像這樣：

$('form').submit(function() { 
    $.ajax({ 
     url: $(this).attr('action'), 
     type: 'POST', 
     data: collectFormData(), 
     dataType: 'xml', 
     contentType: "text/xml; charset=utf-8", 
     success: function (data) { 
      alert('data:'+data) 
     }, 
     error: function (jqXHR, textStatus, errorThrown) { 
      alert('jqXHR:'+jqXHR+'\n'+'textStatus:'+'\n'+textStatus+'errorThrown:'+errorThrown); 
     } 
    }); 

    return false; 
}); 

也驗證次在您的XML數據從版本和編碼開始：

<?xml version="1.0" encoding="UTF-8"?> 

Answer 2

您的控制器只接受JSON。它永遠不會消耗XML.Try使它消耗兩個：

@RequestMapping(value="/save", 
       method=RequestMethod.POST, 
       consumes={"application/json", "application/xml"})
