JAX-RS和自定义授权 [英] JAX-RS and custom authorization

问题描述

我正在尝试保护JAX-RS端点，目前正在尝试弄清楚身份验证和授权是如何工作的。大多数示例都非常简单，因为它们只是通过web.xml从Java EE App-Server角色中捎带。

I'm trying to secure the JAX-RS endpoint and am currently trying to figure out how the authentication and authorization work. Most examples are quite simple as they only piggyback from Java EE App-Server role via web.xml.

我想知道如何使用除Java EE AS以外的其他东西角色。例如：我想使用会话或某种令牌（或某种标识符）。

I'm wondering how to use something else than the Java EE AS roles. For example: I'd like to use session or some sort of token (or some sort of identifier).

推荐答案

这一切取决于您正在使用的JAX-RS实现。我在嵌入式 Jersey /docs.codehaus.org/display/JETTY/Jetty+Documentation\"rel =noreferrer> Jetty 。

It all depends upon the JAX-RS implementation you're using. I'm using Jersey on embedded Jetty.

SecurityHandler sh = new SecurityHandler();

// the UserRealm is the collection of users, and a mechanism to determine if
// provided credentials are valid
sh.setUserRealm(new MyUserRealm());

// the Authenticator is a strategy for extracting authentication credentials
// from the request. BasicAuthenticator uses HTTP Basic Auth
sh.setAuthenticator(new BasicAuthenticator());

一旦你拥有< HttpServletRequest 中的code> Principal ，您可以将这些注入到JAX-RS请求的上下文中。

Once you have the Principal in the HttpServletRequest, you can inject these into the context of the JAX-RS request.

public abstract class AbstractResource {
    private Principal principal;
    @Context
    public void setSecurityContext(SecurityContext context) {
        principal = context.getUserPrincipal();
    }
    protected Principal getPrincipal() {
        return principal;
    }
}

@Path("/some/path")
public class MyResource extends AbstractResource {
    @GET
    public Object get() {
        Principal user = this.getPrincipal();
        // etc
    }
}
