gstackoverflow Asks: How to add security for spring 5 websockets Everything works as described and aplication looks fine. I just have a nice controller: Code: @Controller
public class GreetingController {
@MessageMapping("/hello")
@SendTo("/topic/greetings")
public Greeting greeting(HelloMessage message) throws Exception {
Thread.sleep(1000); // simulated delay
return new Greeting("Hello, " + HtmlUtils.htmlEscape(message.getName()) + "!");
}
} And a bit configuration. Now I want to add security for this simple application. I spent time to find an example but I could not find it. Generally I've found the tutorial: Preview Spring Security WebSocket Support But looks like this example relevant for spring 4 only rather than
spring 5. And I don't understand where should I provide credentials and so on. Description is not enough detailed to apply it for my example. One more tutorial I've found: Websocket Authentication and Authorization in Spring Ask It looks more clear but I am
not sure that it is the best solution for now. Can you advise the simplest way to configure spring security for my application? P.S. Also I've found not the same but familiar question How to secure websocket application [Spring boot + STOMP] but there are no answers at the moment. Now I have following configuration: Code: @Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractSecurityWebSocketMessageBrokerConfigurer {
private static String[] authorities = new String[]{
"VIEW_SCRIPT_TAB", "VIEW_CREDS_TAB"
};
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry
.addEndpoint("/gs-guide-websocket")
.addInterceptors(new HandshakeInterceptor() {
@Override
public boolean beforeHandshake(ServerHttpRequest request, ServerHttpResponse response, WebSocketHandler wsHandler, Map<String, Object> attributes) throws Exception {
System.out.println("Handshake interceptor beforeHandshake");
return true;
}
@Override
public void afterHandshake(ServerHttpRequest request, ServerHttpResponse response, WebSocketHandler wsHandler, @Nullable Exception exception) {
System.out.println("Handshake interceptor after");
}
})
.withSockJS();
}
@Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
registry.enableSimpleBroker("/topic");
registry.setApplicationDestinationPrefixes("/app");
}
@Override
protected void configureInbound(MessageSecurityMetadataSourceRegistry message) {
message
.nullDestMatcher().permitAll()
.simpDestMatchers("/app/**").hasAnyAuthority(authorities)
.simpSubscribeDestMatchers("/topic/**").permitAll()
.anyMessage().denyAll();
}
} Bit when I start application I see stacktrace: Code: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'stompWebSocketHandlerMapping' defined in class path resource [org/springframework/web/socket/config/annotation/DelegatingWebSocketMessageBrokerConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.HandlerMapping]: Factory method 'stompWebSocketHandlerMapping' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'subProtocolWebSocketHandler' defined in class path resource [org/springframework/web/socket/config/annotation/DelegatingWebSocketMessageBrokerConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.socket.WebSocketHandler]: Factory method 'subProtocolWebSocketHandler' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'clientInboundChannel' defined in class path resource [org/springframework/web/socket/config/annotation/DelegatingWebSocketMessageBrokerConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.messaging.support.AbstractSubscribableChannel]: Factory method 'clientInboundChannel' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'clientInboundChannelExecutor' defined in class path resource [org/springframework/web/socket/config/annotation/DelegatingWebSocketMessageBrokerConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor]: Factory method 'clientInboundChannelExecutor' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'inboundChannelSecurity' defined in class path resource [com/my/ws/example/ws_example/hello/WebSocketConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.security.messaging.access.intercept.ChannelSecurityInterceptor]: Factory method 'inboundChannelSecurity' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'inboundMessageSecurityMetadataSource' defined in class path resource [com/my/ws/example/ws_example/hello/WebSocketConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.security.messaging.access.intercept.MessageSecurityMetadataSource]: Factory method 'inboundMessageSecurityMetadataSource' threw exception; nested exception is java.lang.NoSuchMethodError: org.springframework.security.messaging.access.expression.ExpressionBasedMessageSecurityMetadataSourceFactory.createExpressionMessageMetadataSource(Ljava/util/LinkedHashMap;Lorg/springframework/security/access/expression/SecurityExpressionHandler;)Lorg/springframework/security/messaging/access/intercept/MessageSecurityMetadataSource;

nop Asks: Visual Studio 2022 hangs when open Razor file When I open the _Imports.razor, not a problem. Open NavMenu.razor, a problem. The IDE opens the file, displays formatted Razor and after a couple of seconds just hangs, CPU usage for devenv.exe goes 50% and stays there until End Task.
Any idea how to fix this? The IDE should not hang when I try and work with a Razor file. SolveForum.com may not be responsible for the answers or solutions given to any question asked by the users.

samoht9277 Asks: FFMPEG - infinite file video stream to RTMP server Here is a similat question, but it
doesn't fully answer what I need. At my first attempt, I made a bash script that spawned a new ffmpeg instance for each video I was trying to stream. I noticed that that the few seconds that takes to spawn the new instance interrupts the stream. After I noticed this problem, I decided to google some kind of queue system, and I found that ffmpeg has a concat function, that reads a file with a custom syntax and queues it. So I made a script
that lists the files in the directory where I store all my videos, modifies the output with sed, shuffles it (so the episodes are random), and then it redirects the output to a playlist.txt Code: find /mnt/episode/ -print | sed '/**.mp4/!d' | sed "s/^/file '/; s/$/'/" | shuf > playlist.txt Code: ...
file '/mnt/episode/9/1.mp4'
file '/mnt/episode/8/4.mp4'
file '/mnt/episode/5/11.mp4'
file '/mnt/episode/7/15.mp4'
... Code: ffmpeg -f concat -safe 0 -i playlist.txt -f v4l2 /dev/video0 (simplified command, using /dev/video0 device for testing purposes) ffmpeg does output something after the first video, but i'm not quite sure what it means. Code: [mov,mp4,m4a,3gp,3g2,mj2 @ 0x55c8abc1b900] st: 1 edit list: 1 Missing key frame while searching for timestamp: 0
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x55c8abc1b900] st: 1 edit list 1 Cannot find an index entry before timestamp: 0. I need a way to pick a random file, stream it normally via RTMP and once it finished, automatically pick another one without interrupting the streaming, and keep doing this until I decide to turn it off. I have this directory, with these .mp4 files. Code: episodes
