ajax提交form表单后台@RequestBody接收json字符串

好久没搞ajax提交form表单了。

在修改过程中遇到报错：

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

这里因为是post提交，需要修改

contentType : 'application/json'

2、Caused by: com.fasterxml.jackson.core.JsonParseException: Unrecognized token 'name': was expecting

这里是因为使用了

$("#jmExaminationSave").serialize()

解决方案

var formObject = {};
var formArray =$("#jmExaminationSave").serializeArray();
$.each(formArray,function(i,item){
    formObject[item.name] = item.value;
});

完整代码

js事件

function saveForm() {
    $("#save_btn").attr("disabled","disabled");
    var formObject = {};
    var formArray =$("#jmExaminationSave").serializeArray();
    $.each(formArray,function(i,item){
        formObject[item.name] = item.value;
    });
    formObject.jmDocID=$("#jmDocID").val();
    var url ="<%=path %>/physicalExamination/jmExaminationSave.action";
    $.ajax({
        url: url,
        type: "post",
        data: JSON.stringify(formObject),
        contentType : 'application/json',
        dataType: "json",
        success: function (data) {
            debugger
            $("#save_btn").removeAttr("disabled");
            if (data.code == 0) {
                layer.open({
                    title: '提示'
                    ,content: '提交成功!'
                });
            }
        },
        error : function() {
            $("#save_btn").removeAttr("disabled");
            layer.open({
                title: '提示'
                ,content: '操作异常!'
            });
        }
    });
}

jsp页面

<button type="button" id = "save_btn" class="am-btn am-btn-primary am-btn-xs" οnclick="saveForm()">提交保存
