spring-mvc - 带有 Spring WebSocket 的 SockJS 客户端 - CORS

Question

我正在尝试在后端和前端使用 Spring Sockets 实现 websockets 我正在使用 sockjs、stomp 和 angular 2。当我尝试将 sockjs 与 spring 连接时，出现以下错误

在浏览器控制台中:

stomp.min.js:8 Opening Web Socket...

在后端控制台中:

我的配置类是WebSocketConfig

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {

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

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/hello").withSockJS();
    }

}

MvcWebApplicationInitializer

public class MvcWebApplicationInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

@Override
  protected void customizeRegistration(ServletRegistration.Dynamic registration) {
    registration.setInitParameter("dispatchOptionsRequest", "true");
    registration.setAsyncSupported(true);
  }

@Override
protected Class<?>[] getRootConfigClasses() {
    return new Class[] { SecurityConfiguration.class, WebSocketConfig.class };
}

@Override
protected Class<?>[] getServletConfigClasses() {
    // TODO Auto-generated method stub
    return new Class<?>[] { WebConfig.class };
}

@Override
protected String[] getServletMappings() {
    // TODO Auto-generated method stub
    return new String[] { "/" };
}

//...其他覆盖...

Answer 1

在您的 web.xml 中，您必须使用 true 添加您的 servlet。不仅适用于过滤器，也适用于 servlet。示例:

<servlet>
    <servlet-name>appServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            /WEB-INF/spring/appServlet/servlet-context.xml
        </param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
    <async-supported>true</async-supported>
</servlet>
