java - 基于 XML 和 Annotations 的 Spring Websockets

问题描述

我正在尝试在 websocket + spring security + springBoot 上编写自己的聊天。现在我的项目中有：

安全上下文.xml：

    ...
            <intercept-url pattern="/login/**" access="IS_AUTHENTICATED_ANONYMOUSLY"/>
            <intercept-url pattern="/resources/**" access="IS_AUTHENTICATED_ANONYMOUSLY"/>
            <intercept-url pattern="/**" access="ROLE_USER" />
            <form-login/>
        </http>

        <authentication-manager>
            <authentication-provider>
                <user-service>
                    <user name="bob" password="test" authorities="ROLE_USER"/>
                    <user name="jim" password="test" authorities="ROLE_USER"/>
                    <user name="a" password="1" authorities="ROLE_USER"/>
...

servlet-context.xml

<context:annotation-config/>
    <context:component-scan base-package="wsproblem" use-default-filters="false">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
    <mvc:annotation-driven />
    <mvc:resources mapping="/resources/**" location="/resources/" />
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/" />
        <property name="suffix" value=".jsp" />
    </bean>
    <websocket:message-broker application-destination-prefix="/app">
        <websocket:stomp-endpoint path="/ws">
            <websocket:sockjs />
        </websocket:stomp-endpoint>
        <websocket:simple-broker prefix="/topic, /user" />
    </websocket:message-broker>

，我有标准的web.xml和root-context.xml。

我还有一个简单的控制器：

@Controller
@RequestMapping("/")
public class HomeController {
    @Autowired private SimpMessagingTemplate simpMessagingTemplate;

    @RequestMapping(method = RequestMethod.GET)
    public String home() {
        return "home";
    }

    @MessageMapping("/greeting")
    public void greeting(Principal principal) {
        String reply = "hello " + principal.getName();
        System.out.println("sending " + reply);
        simpMessagingTemplate.convertAndSendToUser(principal.getName(), "/reply", reply);
    }

我的问题是：

如何将此代码（例如如何迁移）从 xml 重写为带注释的 java 类文件，例如WebSecurityConfig 扩展 AbstractSecurityWebSocketMessageBrokerConfigurer

解决方案

你可以很好地做这样的事情

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.annotation.Configuration;
import org.springframework.messaging.simp.config.MessageBrokerRegistry;
import org.springframework.web.socket.config.annotation.AbstractWebSocketMessageBrokerConfigurer;
import org.springframework.web.socket.config.annotation.EnableWebSocketMessageBroker;
import org.springframework.web.socket.config.annotation.StompEndpointRegistry;

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {

    private static final Logger logger = LoggerFactory.getLogger(WebSocketConfig.class);

    public WebSocketConfig(){
        logger.info("---WebSocket---");
    }

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/temp-ws").withSockJS();
    }

    @Override
    public void configureMessageBroker(MessageBrokerRegistry registry) {
        registry.setApplicationDestinationPrefixes("/temp-web");
        registry.enableSimpleBroker("/queue");   // Enables a simple in-memory broker

        // rabbitmq broker
//        registry.enableStompBrokerRelay("/topic", "/queue")
//                .setRelayHost("localhost")
//                .setRelayPort(61613)
//                .setClientLogin("guest")
//                .setClientPasscode("guest");

    }


}
