Spring 4 WebSocket集成到Spring MVC應用程序

我編寫基於Spring MVC的簡單Web應用程序。 Everything run Ok。然後我創建Endpoint和HandShake類到Terminal (C# Application)通過Websocket與服務器通信。Spring 4 WebSocket集成到Spring MVC應用程序

WebsocketEndPoint.java：

public class WebsocketEndPoint extends BinaryWebSocketHandler { 

    @Override 
    public void afterConnectionEstablished(WebSocketSession session) throws Exception { 
     System.out.println("After Connection Established !!!!"); 
    } 

    @Override 
    protected void handleBinaryMessage(WebSocketSession session, BinaryMessage message) throws Exception { 
     session.sendMessage(message); 
    } 

    @Override 
    public void afterConnectionClosed(WebSocketSession session, CloseStatus closeStatus) throws Exception { 
     System.out.println("After Connection Closed !!!!"); 
    } 

}

HandshakeInterceptor.java：

public class HandshakeInterceptor 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); 
    } 
}

XML配置的WebSocket處理器和攔截：websocketconfig.xml

<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:websocket="http://www.springframework.org/schema/websocket" 
    xsi:schemaLocation=" 
     http://www.springframework.org/schema/beans 
     http://www.springframework.org/schema/beans/spring-beans.xsd 
     http://www.springframework.org/schema/websocket 
     http://www.springframework.org/schema/websocket/spring-websocket.xsd"> 

     <bean id="websocket" class="com.javahash.spring.WebsocketEndPoint"/> 

     <websocket:handlers> 
      <websocket:mapping path="/PaymentHandler" handler="websocket"/> 
      <websocket:handshake-interceptors> 
      <bean class="com.javahash.spring.HandshakeInterceptor"/> 
      </websocket:handshake-interceptors> 
     </websocket:handlers> 
</beans>

添加websocketconfig.xml到Spring應用程序上下文：

web.xml中：

<web-app xmlns="http://java.sun.com/xml/ns/j2ee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" 
    version="2.4"> 

    <display-name>Web server</display-name> 

    <servlet> 
     <servlet-name>webserver</servlet-name> 
     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
     <load-on-startup>1</load-on-startup> 
    </servlet> 

    <servlet-mapping> 
     <servlet-name>dispatcher</servlet-name> 
     <url-pattern>/</url-pattern> 
    </servlet-mapping> 

    <context-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value> 
      /WEB-INF/dispatcher-servlet.xml 
      /WEB-INF/websocketconf.xml 
     </param-value> 
    </context-param> 

    <listener> 
     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
    </listener> 
</web-app>

加入websocketconfig.xml到Spring應用程序上下文後：

終端（C＃應用程序）can communicate with Server via Socket但我can not access web。
我WARNING: No mapping found for HTTP request with URI [Spring4MVCHelloWorld/hello]] in DispatcherServlet with name 'dispatcher'

調度-servlet.xml中：

<beans xmlns="http://www.springframework.org/schema/beans" 
xmlns:context="http://www.springframework.org/schema/context" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation=" 
http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd 
http://www.springframework.org/schema/context 
http://www.springframework.org/schema/context/spring-context-4.0.xsd"> 

    <context:component-scan base-package="com.javahash.spring.controller" /> 

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
     <property name="prefix"> 
      <value>/WEB-INF/views/</value> 
     </property> 
     <property name="suffix"> 
      <value>.jsp</value> 
     </property> 
    </bean> 
</beans>

HelloWorldController.java：

package com.javahash.spring.controller; 

import org.springframework.stereotype.Controller; 
import org.springframework.ui.Model; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestParam; 

@Controller 
public class HelloWorldController { 

    @RequestMapping("/hello") 
    public String hello(@RequestParam(value="name", required=false, defaultValue="World") String name, Model model) { 
     model.addAttribute("name", name); 
     return "helloworld"; 
    } 

}

看來@Controller not effect。

我是否錯過了什麼？

我想你在你的dispatcher-servlet.xml文件中缺少<mvc:annotation-driven/>。 Spring掃描你的Controller bean，但Spring MVC沒有註冊你的映射。
