Content type application/x-www-form-urlencoded；charset=UTF-8 not supported

问题描述:前端向后台发送ajax请求时,后台用map接收没有问题,将map换成dto接收时报此异常

解决办法:

$.ajax({
    type:'post',
    url: $.getRootPath() + '/xxx/saveOrUpdate.do',
    contentType:'application/json;charset=utf-8',
    data: JSON.stringify(formData),
    success: function (data) {
        if (data.success) {
            $.dalert({text: data.msg, icon: 1});
            refreshTableInit(index);
        } else {
            $.dalert({text: data.msg, icon: 2});
        }
    }
})

加上contentType:'application/json;charset=utf-8',和JSON.stringify(formData),
