springboot +vue 整合websocket 403

关键点是 setAllowedOrigins("*")

package com.izenuo.common.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.messaging.simp.config.MessageBrokerRegistry;
import org.springframework.web.socket.config.annotation.AbstractWebSocketMessageBrokerConfigurer;
import org.springframework.web.socket.config.annotation.EnableWebSocketMessageBroker;
import org.springframework.web.socket.config.annotation.StompEndpointRegistry;

/**
 * 通过EnableWebSocketMessageBroker 开启使用STOMP协议来传输基于代理(message broker)的消息,此时浏览器支持使用@MessageMapping 就像支持@RequestMapping一样。
 */
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
 
    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) { //endPoint 注册协议节点,并映射指定的URl

        //注册一个名字为"endpointChat" 的endpoint,并指定 SockJS协议。   点对点-用
        registry.addEndpoint("/endpointChat").setAllowedOrigins("*").withSockJS();
    }


    @Override
    public void configureMessageBroker(MessageBrokerRegistry registry) {//配置消息代理(message broker)
        //点对点式增加一个/queue 消息代理
        registry.enableSimpleBroker("/queue", "/topic");

    }
}
