**SimpMessagingTemplate无法注入问题**

pom文件中引入

<dependency>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-websocket</artifactId>
    </dependency>

创建WebSocketStompConfig.java

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;
    
    /** * @author */
    @Configuration
    @EnableWebSocketMessageBroker
    public class WebSocketStompConfig implements WebSocketMessageBrokerConfigurer { 
    
        /** * 注册stomp端点 * @param registry */
        @Override
        public void registerStompEndpoints(StompEndpointRegistry registry) { 
    
            // 允许使用socketJs方式访问 即可通过http://IP:PORT/xboot/ws来和服务端websocket连接
            registry.addEndpoint("/message/ws").setAllowedOrigins("*").withSockJS();
        }
    
        /** * 配置信息代理 * @param registry */
        @Override
        public void configureMessageBroker(MessageBrokerRegistry registry) { 
    
            // 订阅Broker名称 user点对点 topic广播即群发
            registry.enableSimpleBroker("/user", "/topic");
            // 全局(客户端)使用的消息前缀
            registry.setApplicationDestinationPrefixes("/app");
            // 点对点使用的前缀 无需配置 默认/user
            registry.setUserDestinationPrefix("/user");
        }
    }

就可以解决
