有没有办法在带有@ResponseBody 注释的方法中添加 cookie? [英] Is there any way to add cookie in method with @ResponseBody annotation?

问题描述

我基于 Spring MVC 构建了我的 Web 应用程序，并在尝试在处理 ajax 请求的方法中添加 cookie 时遇到问题.

I build my web application based on Spring MVC and come across a problem whilst trying to add a cookie in a method handling an ajax request.

我意识到带有@ResponseBody 的方法(在我的示例中它返回一个字符串值)不会创建真实"响应并且添加的 cookie 会丢失.

I realized that method with @ResponseBody (in my example it returns a string value) does not create a "real" response and added cookies are lost.

有没有办法在 Spring MVC 中通过 ajax 调用的方法中添加 cookie(因此用 @ResponseBody 进行注释)?

Is there any way to add a cookie in a method called via ajax (and therefore annotated with @ResponseBody) in Spring MVC?

推荐答案

您可以使用以下签名来做到这一点

You can use the following signature to do this

@ResponseBody
public String x((HttpServletRequest request, HttpServletResponse response){
    Cookie userCookie = new Cookie("<name>", "<valie>");
    //set other cookie properties
    response.addCookie(userCookie);

    return "xxx";
}
