在Spring MVC中使用Ajax [英] Using ajax with Spring MVC

问题描述

我目前正在使用Spring MVC，并且尝试使用ajax做一些事情.基本上，我现在要做的是在网页上动态显示控制器的结果.

I am currently using the Spring MVC, and I am trying to do some stuff with ajax. Basically what I want to do now is display the result from a controller dynamically on a webpage.

I.E.用户按下按钮，它会转到"whatever.do"控制器，并获得列表并显示该列表，而无需重新加载该页面.

I.E. A user pushes a button it goes to the "whatever.do" controller and gets a list and displays that list without having to reload that page.

任何人都知道任何好的教程或示例项目吗?

Anyway does anyone know any good tutorials or example projects?

推荐答案

这很简单，我什至不认为不需要专门的教程(除了通用的spring-mvc教程).

It is very simple, I don't even think a special tutorial is needed (apart from a generic spring-mvc one).

1. 制作一个@RequestMapping("/foo")方法，该方法返回一个List<Foo>
2. dispatcher-servlet.xml中具有<mvc:annotation-driven />以激活处理程序映射和转换器
3. 将Jackson(json序列化器)放在类路径上
4. 使用$.getJSON("/foo", function(data) {..});(jquery)-您将获得Foo对象的JSON编码列表

1. Make a @RequestMapping("/foo") method that returns a List<Foo>
2. Have <mvc:annotation-driven /> in your dispatcher-servlet.xml to activate handler mappings and convertors
3. Put Jackson (json serializer) on your classpath
4. Use $.getJSON("/foo", function(data) {..}); (jquery) - you will get a JSON-encoded list of your Foo objects

Spring将检测到浏览器请求json响应，并使用Jackson转换您的对象.

Spring will detect that the browser requests a json response, and converts your objects using Jackson.
