Question

这是一个反复出现的问题，我找不到一些解决方案。但这些都不适用于我。
尝试使用jQuery AJAX发布表单。

注意：我昨天发布了它，认为这是客户端问题。试着在客户端一切可能，但没有运气。

Spring Controller

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


        System.out.println(formData);
}

jQuery请求（尝试了评论中人们建议的所有内容）

如果我发送data:$(this).serialize()和contentType:application/json

，它可以正常工作

$('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;
                });

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

您的控制器只接受JSON。它永远不会消耗XML。尝试使它同时消耗：

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

Answer 2

我认为charset应该在contentType而不是dataType中定义，如下所示：

$('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;
});

同时验证您的XML数据是否以版本和编码开头：

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