【spring+websocket的使用】

一、spring配置文件Java代码

1. <?xml version="1.0" encoding="UTF-8"?>

• <beans xmlns="http://www.springframework.org/schema/beans"
• xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"
• xmlns:context="http://www.springframework.org/schema/context"
• xmlns:mvc="http://www.springframework.org/schema/mvc"
• xmlns:p="http://www.springframework.org/schema/p"
• xmlns:websocket="http://www.springframework.org/schema/websocket"
• xsi:schemaLocation="http://www.springframework.org/schema/beans
• http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
• http://www.springframework.org/schema/tx
• http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
• http://www.springframework.org/schema/context
• http://www.springframework.org/schema/context/spring-context-4.1.xsd
• http://www.springframework.org/schema/mvc
• http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd
• http://www.springframework.org/schema/websocket

• http://www.springframework.org/schema/websocket/spring-websocket-4.1.xsd ">
• <!-- @Autowired等注解驱动 -->
• <context:annotation-config />

• <mvc:annotation-driven/>
• <!--一定要扫描指定的项目报-->

• <context:component-scan base-package="com.soccermaster.websocket"></context:component-scan>
• <context:component-scan base-package="com.soccermaster.service"></context:component-scan>
• <context:component-scan base-package="com.soccermaster.dao"></context:component-scan>

• <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
• <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:viewClass="org.springframework.web.servlet.view.JstlView"
• p:prefix="/WEB-INF/pages/" p:suffix=".jsp">
• </bean>

• </beans>

二、web.xml配置

注意：必须将相应filter和servlet加入

Java代码

1. <async-supported>true</async-supported>

复制代码

1. <?xml version="1.0" encoding="UTF-8"?>

• <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
• <display-name>spring websocket信息推送</display-name>
• <welcome-file-list>
• <welcome-file>testSocket.jsp</welcome-file>
• </welcome-file-list>
• <listener>
• <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
• </listener>
• <listener>
• <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
• </listener>
• <servlet>
• <servlet-name>SpringMVC</servlet-name>
• <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
• <init-param>
• <param-name>contextConfigLocation</param-name>
• <param-value>classpath:spring-mvc.xml</param-value>
• </init-param>
• <load-on-startup>1</load-on-startup>
• <async-supported>true</async-supported>
• </servlet>
• <servlet-mapping>
• <servlet-name>SpringMVC</servlet-name>
• <url-pattern>/</url-pattern>
• </servlet-mapping>
• <context-param>
• <param-name>contextConfigLocation</param-name>
• <param-value>classpath:spring-mybatis.xml</param-value>
• </context-param>
• <filter>
• <filter-name>encodingFilter</filter-name>
• <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
• <async-supported>true</async-supported>
• <init-param>
• <param-name>encoding</param-name>
• <param-value>UTF-8</param-value>
• </init-param>
• </filter>
• <filter-mapping>
• <filter-name>encodingFilter</filter-name>
• <url-pattern>/*</url-pattern>
• </filter-mapping>
• <session-config>
• <session-timeout>30</session-timeout>
• </session-config>
• </web-app>

三、代码

a、websocketconfig

Java代码

1. package com.soccermaster.websocket;

• import org.springframework.context.annotation.Configuration;
• import org.springframework.web.servlet.config.annotation.EnableWebMvc;
• import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
• import org.springframework.web.socket.WebSocketHandler;
• import org.springframework.web.socket.config.annotation.EnableWebSocket;
• import org.springframework.web.socket.config.annotation.WebSocketConfigurer;
• import org.springframework.web.socket.config.annotation.WebSocketHandlerRegistry;
• import org.springframework.context.annotation.Bean;
• @Configuration
• @EnableWebMvc
• @EnableWebSocket
• public class WebSocketConfig extends WebMvcConfigurerAdapter implements WebSocketConfigurer {
• public WebSocketConfig() {
• }
• @Override
• public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
• registry.addHandler(systemWebSocketHandler(), "/websck").addInterceptors(new WebSocketHandshakeInterceptor());
• System.out.println("registed!");
• registry.addHandler(systemWebSocketHandler(), "/sockjs/websck/info").addInterceptors(new WebSocketHandshakeInterceptor()).withSockJS();
• }
• @Bean
• public WebSocketHandler systemWebSocketHandler() {
• //return new InfoSocketEndPoint();
• return new SystemWebSocketHandler();
• }
• }

复制代码

b、WebSocketHandshakeInterceptor

Java代码

1. package com.soccermaster.websocket;

• import java.util.Map;
• import org.springframework.http.server.ServerHttpRequest;
• import org.springframework.http.server.ServerHttpResponse;
• import org.springframework.stereotype.Component;
• import org.springframework.web.socket.WebSocketHandler;
• import org.springframework.web.socket.server.support.HttpSessionHandshakeInterceptor;
• @Component
• public class WebSocketHandshakeInterceptor extends HttpSessionHandshakeInterceptor {
• @Override
• public boolean beforeHandshake(ServerHttpRequest request,
• ServerHttpResponse response, WebSocketHandler wsHandler,
• Map<String, Object> attributes) throws Exception {
• System.out.println("Before Handshake");
• return super.beforeHandshake(request, response, wsHandler, attributes);
• }
• @Override
• public void afterHandshake(ServerHttpRequest request,
• ServerHttpResponse response, WebSocketHandler wsHandler,
• Exception ex) {
• System.out.println("After Handshake");
• super.afterHandshake(request, response, wsHandler, ex);
• }
• }

复制代码

c、SystemWebSocketHandler

Java代码

1. package com.soccermaster.websocket;

• import java.io.IOException;
• import java.util.ArrayList;
• import org.slf4j.Logger;
• import org.slf4j.LoggerFactory;
• import org.springframework.beans.factory.annotation.Autowired;
• import org.springframework.stereotype.Component;
• import org.springframework.web.socket.CloseStatus;
• import org.springframework.web.socket.TextMessage;
• import org.springframework.web.socket.WebSocketHandler;
• import org.springframework.web.socket.WebSocketMessage;
• import org.springframework.web.socket.WebSocketSession;
• <!--例如以下接口是自己的业务接口 依据情况自己定义-->
• import com.soccermaster.service.IMatchService;
• import com.soccermaster.util.json.JsonConvert;
• /**

• *

• */
• @Component
• public class SystemWebSocketHandler implements WebSocketHandler {
• @Autowired
• private IMatchService matchService;
• private static final Logger logger;
• private static final ArrayList<WebSocketSession> users;
• static {
• users = new ArrayList<WebSocketSession>();
• logger = LoggerFactory.getLogger(SystemWebSocketHandler.class);
• }
• @Override
• public void afterConnectionEstablished(WebSocketSession session)
• throws Exception {
• logger.debug("connect to the websocket success......");
• System.out.println("connect to the websocket success......");
• session.sendMessage(new TextMessage("Server:connected OK!"));
• users.add(session);
• }
• @Override
• public void handleMessage(WebSocketSession wss, WebSocketMessage<?

  > wsm)

• throws Exception {
• logger.debug("websocket handle message......");
• TextMessage returnMessage = new TextMessage(result);
• wss.sendMessage("服务端返回信息");
• //sendMessageToUsers(wss, wsm);
• }
• @Override
• public void handleTransportError(WebSocketSession wss, Throwable thrwbl)
• throws Exception {
• if (wss.isOpen()) {
• wss.close();
• }
• users.remove(wss);
• logger.debug("websocket connection closed happen error......");
• System.out.println("websocket connection closed happen error......");
• }
• @Override
• public void afterConnectionClosed(WebSocketSession wss, CloseStatus cs)
• throws Exception {
• System.out.println("websocket connection closed......");
• users.remove(wss);
• logger.debug("websocket connection closed......");
• }
• @Override
• public boolean supportsPartialMessages() {
• return false;
• }
• }
