我正在尝试将我的react.jsocks客户端连接到我的spring boot后端Web套接字，但我无法连接它们，它在chrome控制台上给了我一些错误，如下所示：
chrome 控制台错误
我的 Spring Boot 部分没有任何错误，但有一些类似的警告：
弹簧启动控制台
为什么我无法连接它们我的react.js部分是这样的：

和我的 Spring Boot 配置类：
package com.project.blog.websocket;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.messaging.simp.config.MessageBrokerRegistry;
import org.springframework.web.socket.config.annotation.EnableWebSocketMessageBroker;
import org.springframework.web.socket.config.annotation.StompEndpointRegistry;
import org.springframework.web.socket.config.annotation.WebSocketMessageBrokerConfigurer;
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfiguration implements WebSocketMessageBrokerConfigurer {
@Value("${blog.app.front}")
private String url;
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/wss").setAllowedOrigins(url).setAllowedOriginPatterns("*").withSockJS();
}
@Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
registry.setApplicationDestinationPrefixes("/app");
registry.enableSimpleBroker("/user-connect");
registry.setUserDestinationPrefix("/user");
}
}
同样对于网络套接字控制器我写了这部分：
package com.project.blog.websocket;
import com.project.blog.entities.User;
import com.project.blog.repositories.UserRepository;
import com.project.blog.responses.ErrorSuccessResponse;
import lombok.RequiredArgsConstructor;
import org.springframework.messaging.handler.annotation.MessageMapping;
import org.springframework.messaging.simp.SimpMessagingTemplate;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Controller;
import java.time.LocalDateTime;
import java.util.LinkedList;
import java.util.List;
@Controller
@RequiredArgsConstructor
public class WebSocketController {
private final SimpMessagingTemplate simpMessagingTemplate;
private final UserRepository userRepository;
@MessageMapping("/message")
private ErrorSuccessResponse receiveMessage(String user){
ErrorSuccessResponse errorSuccessResponse = new ErrorSuccessResponse();
errorSuccessResponse.setError("block oldu");
simpMessagingTemplate.convertAndSendToUser(user,"/private",errorSuccessResponse);
return errorSuccessResponse;
}
@Scheduled(fixedDelay = 1000)
private void checkBlocks(){
LocalDateTime now = LocalDateTime.now();
List users = userRepository.findBlockedUsers(now);
users.stream().forEach(user->{
receiveMessage(user.getUsername());
});
}
}
我尝试使用袜子连接我的react.js前端和spring boot后端，但我做不到
我的 process.env.REACT_APP_ROOT_URL 是：http://localhost:1998 和@Value(“${blog.app.front}”) 私有字符串 url；这部分值是：http://localhost:3000
