的NoSuchMethodError WebUtils.isValidOrigin春天的WebSocket

這裏是我的設置在春天一個簡單的WebSocket控制器：的NoSuchMethodError WebUtils.isValidOrigin春天的WebSocket

@Controller 
@RequestMapping("/myHandler") 
public class MyHandler extends TextWebSocketHandler { 
    public void handleTextMessage(WebSocketSession session, TextMessage message) throws Exception { 
     String reply = "Hello there!!!!!!!!"; 
     session.sendMessage(new TextMessage(reply)); 
    } 
}

MCV-調度-servlet.xml中

<websocket:handlers allowed-origins="http://localhost"> 
    <websocket:mapping path="/myHandler" handler="myHandler"/> 
    <websocket:handshake-interceptors> 
     <bean class="org.springframework.web.socket.server.support.HttpSessionHandshakeInterceptor"/> 
    </websocket:handshake-interceptors> 
</websocket:handlers> 

<bean id="myHandler" class="com.aexp.socket.MyHandler"/>

我所有的jar文件更新正確版本但我得到以下錯誤：

HTTP Status 500 - Request processing failed; nested exception is org.springframework.web.socket.server.HandshakeFailureException: Uncaught failure for request http://localhost:8080/Websocket/myHandler; nested exception is java.lang.NoSuchMethodError: org.springframework.web.util.WebUtils.isValidOrigin(Lorg/springframework/http/HttpRequest;Ljava/util/Collection;)Z 

root cause 

org.springframework.web.socket.server.HandshakeFailureException: Uncaught failure for request http://localhost:8080/Websocket/myHandler; nested exception is java.lang.NoSuchMethodError: org.springframework.web.util.WebUtils.isValidOrigin(Lorg/springframework/http/HttpRequest;Ljava/util/Collection;)Z

javax.servlet.http.HttpServlet.service(HttpServlet.java:729) 
org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)

而當我嘗試克至在JS創建的WebSocket對象我得到以下幾點：

(Opcode -1)

這是我第一次嘗試使用WebSockets所以不知道我錯過了什麼。有人能指引我走向正確的方向嗎？謝謝。

嘗試修改您的.xml配置如下：

<websocket:handlers allowed-origins="http://localhost"> 
    <websocket:mapping path="/myHandler" handler="myHandler"/> 
    <websocket:handshake-interceptors> 
    <bean class="org.springframework.web.socket.server.support.HttpSessionHandshakeInterceptor"/> 
    <websocket:sockjs/> 
</websocket:handshake-interceptors>

希望這有助於！

您錯過了「spring-web」依賴關係。以下內容添加到您的POM：

<dependency> 
    <groupId>org.springframework</groupId> 
    <artifactId>spring-web</artifactId> 
    <version>${spring.version}</version> 
</dependency>

你也可能需要運行「乾淨」的目標，並重建項目。
