Jquery:将数据发布到jsp方法?
原标题:Jquery: post data to a jsp method?

我目前是一个asp.net的家伙,但现在必须做一些jsp工作。我知道在asp.net中,你可以定义一个带有<code>〔WebMethod〕</code>属性的公共静态方法,例如。

  [WebMethod]
  public static string GetIt(string code)
  {
    return GetSomething(code);
  }

然后,我可以在jquery中调用这个方法

$.ajax({
  type: "POST",
  url: "PageName.aspx/GetIt",
  data: "{ code : +$("#code").val()+" }",
  contentType: "application/json; charset=utf-8",
  dataType: "json",
  success: function(msg) {
    // Do something interesting here.
  }
});

有人能告诉我如何使用jsp吗?

最佳回答

使用纯jsp和servlet,您必须做很多事情才能实现这一点。

使用springmvc,几乎与您展示的方式相同:

  • create a class and annotate it with @Controller
  • 创建如下方法:

    @RequestMapping("/path/get")
    @ResponseBody
    public String getIt() {
        ...
    }
    
  • 您将需要<;mvc:注释驱动/>和类路径上的jackson。

请注意,您正在调用“get”,因此逻辑http方法是get,而不是POST
