当SockJS客户端获取http：// localhost / sockjs-endpoint / info？t = xx时出现错误404

Question

在尝试将SockJS客户端连接到spring服务器时遇到错误。 看来SockJS客户端找不到必要的信息-> Network and console display of error

WebSocketConfig.java

public class WebSocketConfig extends AbstractSecurityWebSocketMessageBrokerConfigurer {

    @Override
    public void configureMessageBroker(MessageBrokerRegistry registry) {
        registry.enableSimpleBroker("/project");
        registry.setApplicationDestinationPrefixes("/app");
    }

    /*@Override
    protected void configureInbound(MessageSecurityMetadataSourceRegistry messages) {
        messages.simpDestMatchers("/project/**").permitAll()
            .anyMessage().permitAll();
    }*/

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/sockjs-endpoint").setAllowedOrigins("http://localhost:3000").withSockJS();
    }
}

SockJS客户端

const socketjs2 = new SockJS('http://127.0.0.1:8080/sockjs-endpoint');
export const stomp2 = Stomp.over(socketjs2);

stomp2.connect({}, function (frame) {
    console.log("STOMP connected :");
    console.log(frame);
    stomp2.subscribe('/project/staff', function (requests){
        logger(JSON.parse(requests), LOGGING_INFORMATIONS);
    }).then(function () {
        console.log("sendind to stomp.")
        stomp2.send('/app');
    });
});

SecurityConfig.java

@Bean
CorsConfigurationSource corsConfigurationSource() {
    CorsConfiguration configuration = new CorsConfiguration();
    configuration.setAllowedOrigins(Arrays.asList("http://localhost:3000"));
    configuration.setAllowCredentials(true);
    configuration.setAllowedMethods(Arrays.asList("GET", "PUT", "POST", "DELETE"));
    UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    source.registerCorsConfiguration("/**", configuration);
    return source;
