ssm架构，easyUI做视图层，当有时间参数传入后台时，会发生下列错误：

console报错是这样，但是页面报错400，请求错误，但是还会报一些奇怪的错误令人费解：


Uncaught SyntaxError: Unexpected token <

很具有迷惑性。

这里其实是springmvc在进行对象封装的时候对时间字段需要我们自己在controller层进行格式化，下面将这段代码添加到controller层就好

/**
     * 数据初始化绑定：SpringMVC中，数据从前台过来会将字符串转换为日期对象
     * @param binder
     */
     @InitBinder
     public void initBinder(WebDataBinder binder) {
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm");//格式根据个人需求进行设定
        dateFormat.setLenient(false);
        binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));   //true:允许输入空值，日期可以为空，false:不能为空值
    }
