如何在REST Jersey Web Application中创建，管理和关联会话 [英] How to create, manage, associate a session in REST Jersey Web Application

问题描述

HTML5 UI连接到后端（REST Jersey到业务逻辑到Hibernate和DB）。
我需要为每个用户登录创建和维护一个会话，直到用户退出。

A HTML5 UI is connected to the backend (REST Jersey to business logic to Hibernate and DB). I need to create and maintain a session for each user login until the user logs out.

您能否指导我使用哪些技术/ API？ 。
还需要在REST客户端处理某些事情..

Can you please guide me on what technologies/ APIs can be used. Does something need to be handled at the REST Client end also..

推荐答案

使用JAX-RS进行RESTful Web服务相当简单。以下是基础知识。您通常通过 JAX-RS注释，如下所示：

Using JAX-RS for RESTful web services is fairly straightforward. Here are the basics. You usually define one or more service classes/interfaces that define your REST operations via JAX-RS annotations, like this one:

@Path("/user")
public class UserService {
    // ...
}

您可以通过这些注释在您的方法中自动注入对象：

You can have your objects automagically injected in your methods via these annotations:

// Note: you could even inject this as a method parameter
@Context private HttpServletRequest request;

@POST
@Path("/authenticate")
public String authenticate(@FormParam("username") String username, 
        @FormParam("password") String password) {

    // Implementation of your authentication logic
    if (authenticate(username, password)) {
        request.getSession(true);
        // Set the session attributes as you wish
    }
}

HTTP会话可从 HTTP Request 对象通过 getSession（）和 getSession（boolean）照常。其他有用的注释是 @RequestParam ， @CookieParam 甚至 @MatrixParam 其他许多人。

HTTP Sessions are accessible from the HTTP Request object via getSession() and getSession(boolean) as usual. Other useful annotations are @RequestParam, @CookieParam or even @MatrixParam among many others.

有关详细信息，您可以阅读 RESTEasy用户指南或泽西用户指南，因为两者都是很好的资源。

For further info you may want to read the RESTEasy User Guide or the Jersey User Guide since both are excellent resources.
