Spring MVC:HTTP会话管理“等效" [英] Spring MVC: HTTP session management "equivalent"

问题描述

我来自PHP或ColdFusion之类的语言:如果我想在用户的http会话中保存某些内容，我会这样操作:

I come from languages like PHP or ColdFusion: if I wanted to save something in user's http session I act like this:

SESSION["foo"] = "bar"

现在我处于Spring MVC环境中.

Now I am in a Spring MVC environment.

例如，在Controller方法内部，如何在会话中保存变量?

For example, inside a Controller method, how can I save a variable in session?

有人告诉我，一个会话范围的bean 会得到这份工作.

Someone told me that a session-scoped bean would get the job.

您能帮我提供一个简短的代码段吗?

Can you help me with a trivial code snippet?

推荐答案

您可以使用会话范围的bean，并且在所有请求处理方法上也可以使用HttpServletRequest或HttpSession类型的参数.参见

You may use a session-scoped bean, and you may also have an argument of type HttpServletRequest or HttpSession on all your request handling methods. See http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/htmlsingle/spring-framework-reference.html#mvc-ann-methods.

@RequestMapping...)
public String processSubmit(..., HttpSession session, ...) {
    ...
    session.setAttribute("someAttribute", someObject);
    ...
}
