jQuery:将数据发布到jsp方法? [英] Jquery: post data to a jsp method?

问题描述

我目前是一个asp.net的人，但是现在必须做一些jsp的工作.我知道在asp.net中，您可以使用[WebMethod]属性定义一个公共静态方法.

I am currently a asp.net guy, but have to do some jsp work now. I know that in asp.net, you can define a public static method with [WebMethod] attribute e.g.

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

然后，我可以在jquery中调用此方法

then, I can call this method in jquery

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

有人可以给我一些使用jsp的方法吗?

can someone give me some light how to do it using jsp?

推荐答案

使用纯jsp和servlet，您将需要做很多事情来实现这一目标.

With pure jsp and servlets you'll have to do a lot of things to achieve that.

使用 spring-mvc ，几乎与您显示的方式相同:

It can easily be done with spring-mvc, almost in the same way you showed:

• 创建一个类并用@Controller
对其进行注释

• 创建如下所示的方法:

• create a class and annotate it with @Controller

• create the method to be like this:

@RequestMapping("/path/get")
@ResponseBody
public String getIt() {
    ...
}

在类路径上需要<mvc:annotation-driven />和jackson.

you'll need <mvc:annotation-driven /> and jackson on your classpath.

请注意，您正在调用"get"，因此逻辑http方法是GET，而不是POST

Note that you are calling "get", so the logical http method is GET, rather than POST
