@CookieValue注解
Spring MVC提供@CookieValue方便我们获取指定Cookie数据。
1 设计表单
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>一点教程网 - www.yiidian.com</title>
</head>
<body>
<h2>使用@CookieValue获取Cookie数据</h2>
<a href="/param.do">获取Cookie</a>
</body>
</html>
2 编写Controller
package com.yiidian.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.CookieValue;
import org.springframework.web.bind.annotation.RequestHeader;
import org.springframework.web.bind.annotation.RequestMapping;
/**
* @CookieValue注解获取指定Cookie数据
* 一点教程网 - www.yiidian.com
*/
@Controller
public class CookieController {
@RequestMapping("/cookie.do")
public String save(@CookieValue("JSESSIONID") String sessionId){
System.out.println("JSESSIONID---"+sessionId);
return "success";
}
}
注意：这里获取了JSESSIONID这个Cookie值，当然也可以获取其他Cookie值。
3 springmvc.xml配置
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<!-- 1.扫描Controller的包-->
<context:component-scan base-package="com.yiidian.controller"/>
<!-- 2.配置视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 2.1 页面前缀 -->
<property name="prefix" value="/pages/"/>
<!-- 2.2 页面后缀 -->
<property name="suffix" value=".jsp"/>
</bean>
<!-- 3.创建处理器适配器和处理器映射器-->
<mvc:annotation-driven/>
</beans>
