SpringBoot下Cookie和Session简单使用

cookie

// 获取浏览器端cookie数组
Cookie[] cookies = request.getCookies();
// 循环遍历cookie
for (Cookie cookie : cookies) {
	System.out.printf("key:%s value:%s\n", cookie.getName(), cookie.getValue());
}

// 创建一个新cookie
Cookie cookie = new Cookie("key", "value");
// 过期时间60秒
cookie.setMaxAge(60);
// 返回cookie到客户端
response.addCookie(cookie);

session

// 获取服务器端session对象
HttpSession session = request.getSession();
// 将key和value写入session
session.setAttribute("key1", "value1");
// 获取session值
String key1 = (String) session.getAttribute("key1");
