java - 使用 spring-security 和来自 websocket 消息的访问主体来保护 Spring-Websocket

Question

Spring Security 是一个非常好的框架，广泛用于身份验证和授权。

我有一个要求，其中应用程序使用 j_spring_security_check 进行身份验证，并且只有授权用户才能向 websocket 处理程序发出请求。

我已经根据 http://malalanayake.wordpress.com/2014/06/27/spring-security-on-rest-api/ 配置了 Spring Security

而且我已经根据 http://syntx.io/using-websockets-in-java-using-spring-4/ 配置了 websocket .

我希望从 handleTextMessage 处理程序访问 MyPrincipal 主体对象，如下所示:

    @Override
    protected void handleTextMessage(WebSocketSession session,
            TextMessage message) throws Exception {
        System.out.println("Protocol: "+session.getAcceptedProtocol());
        TextMessage returnMessage = new TextMessage(message.getPayload()
                + " received at server");
        System.out.println("myAttrib="
                + session.getAttributes().get("myAttrib"));
        MyPrincipal user = (MyPrincipal) ((Authentication) session
                .getPrincipal()).getPrincipal();
        System.out.println("User: " + user.getUserId());
        session.sendMessage(returnMessage);
    }

在 websocket 配置中添加 HttpSessionHandshakeInterceptor 允许将 spring 安全主体对象从 SpringSecurityContext 传递到 WebsocketSession

编辑:握手拦截器.java

public class HandshakeInterceptor extends HttpSessionHandshakeInterceptor{

    @Override
    public boolean beforeHandshake(ServerHttpRequest request,
            ServerHttpResponse response, WebSocketHandler wsHandler,
            Map<String, Object> attributes) throws Exception {
        System.out.println("Before Handshake");
        return super.beforeHandshake(request, response, wsHandler, attributes);
    }

    @Override
    public void afterHandshake(ServerHttpRequest request,
            ServerHttpResponse response, WebSocketHandler wsHandler,
            Exception ex) {
        System.out.println("After Handshake");
        super.afterHandshake(request, response, wsHandler, ex);
    }

}

websocket.xml

<bean id="websocket" class="co.syntx.example.websocket.handler.WebsocketEndPoint"/>

<websocket:handlers>
    <websocket:mapping path="/websocket" handler="websocket"/>
    <websocket:handshake-interceptors>
    <bean class="co.syntx.example.websocket.HandshakeInterceptor"/>
    </websocket:handshake-interceptors>
</websocket:handlers>
