ajax,springmvc,json新手使用

老是使用jsp传数据感觉没有跟上时代。所有就课外学习了一下ajax,和json传值。并且用在springmvc框架中

 

前台页面:

<html>
<head>
    <title></title>
    <script src="js/jquery-1.9.1.min.js"></script>
    <script language="Javascript">
        function checkUserid() {
            $.ajax({
                type : 'post',
                data : {
                    mainScore : $("#userid").val(),

                },
                url : "test.do",
                success : function(data) {
                    alert(data);
                },
                error : function() {
                },
                complete : function() {
                }
            });
        }
    </script>
</head>
<body>
用户ID:
<input type="text" id="userid" name="userid"> <span id="msg"></span>
<br> <button onclick="checkUserid()">传输</button>
<p></p>
</body>
</html>

 web.xml

<servlet>
        <servlet-name>DispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springmvc.xml</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>DispatcherServlet</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>

controller设置

@Controller
public class test
{
    @RequestMapping("test")
    public @ResponseBody List<String> test(String mainScore){
        List<String> data=new ArrayList<String>();
        data.add(mainScore);
        return data;
    }
}

 springmvc的配置文件没发出来,我相信你们应该没问题。如有问题,请百度
