Springboot websockets 无法建立连接java.lang.NoSuchMethodError
Springboot websockets unable to establish connection java.lang.NoSuchMethodError
我正在尝试在我的应用程序中使用 websockets 来提供一对一的私人消息传递。在我的实施过程中,我一直在关注 this 项目。通过我在 angular 中的前端项目,我能够与作者 github 的克隆聊天服务建立连接,但是当我尝试连接到我自己的时,我收到此错误:
2020-11-04 19:21:53.918 ERROR 21648 --- [nio-7000-exec-9] o.s.w.s.m.StompSubProtocolHandler : Failed to parse TextMessage payload=[CONNECT
ac..], byteCount=56, last=true] in session 0vmhpgm0. Sending STOMP ERROR to client.

我的项目和另一个项目之间的唯一区别是我使用的是 postgres,所以我的回购和服务不同,但是在错误之前从未到达此代码,因为我在各处放置了断点并且 none 命中。
我无法弄清楚这个错误的真正含义,因为它非常模糊,没有指向任何特定方向。
我的配置:
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {
@Override
public void configureMessageBroker(MessageBrokerRegistry config) {
config.enableSimpleBroker("/user");
config.setApplicationDestinationPrefixes("/app");
config.setUserDestinationPrefix("/user");
}
@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry
.addEndpoint("/ws")
.setAllowedOrigins("*")
.withSockJS();
}
@Override
public boolean configureMessageConverters(List<MessageConverter> messageConverters) {
DefaultContentTypeResolver resolver = new DefaultContentTypeResolver();
resolver.setDefaultMimeType(MimeTypeUtils.APPLICATION_JSON);
MappingJackson2MessageConverter converter = new MappingJackson2MessageConverter();
converter.setObjectMapper(new ObjectMapper());
converter.setContentTypeResolver(resolver);
messageConverters.add(converter);
return false;
}
}
聊天控制器:
@Controller
public class ChatController {
@Autowired private SimpMessagingTemplate messagingTemplate;
@Autowired private ChatMessageService chatMessageService;
@Autowired private ChatRoomService chatRoomService;
@MessageMapping("/chat")
public void processMessage(@Payload ChatMessage chatMessage) {
var chatId = chatRoomService
.getChatId(chatMessage.getSenderId(), chatMessage.getRecipientId(), true);
chatMessage.setChatId(chatId.get());
ChatMessage saved = chatMessageService.save(chatMessage);
messagingTemplate.convertAndSendToUser(
chatMessage.getRecipientId().toString(),"/queue/messages",
new ChatNotification(
saved.getId(),
saved.getSenderId(),
saved.getSenderName()));
}
@GetMapping("/messages/{senderId}/{recipientId}/count")
public ResponseEntity<Long> countNewMessages(
@PathVariable UUID senderId,
@PathVariable UUID recipientId) {
return ResponseEntity
.ok(chatMessageService.countNewMessages(senderId, recipientId));
}
@GetMapping("/messages/{senderId}/{recipientId}")
public ResponseEntity<?> findChatMessages ( @PathVariable UUID senderId,
@PathVariable UUID recipientId) {
return ResponseEntity
.ok(chatMessageService.findChatMessages(senderId, recipientId));
}
@GetMapping("/messages/{id}")
public ResponseEntity<?> findMessage ( @PathVariable UUID id) {
return ResponseEntity
.ok(chatMessageService.findById(id));
}
}
正如我所说,我的前端应该没有问题,因为它正在与另一个后端连接,但为了确保这是我的 angular 片段:
import * as Stomp from 'stompjs';
import * as SockJS from 'sockjs-client';
// ...
connect() {
const sockJS = new SockJS(API_URL + 'ws');
this.stompClient = Stomp.over(sockJS);
this.stompClient.connect({}, this.onConnected, this.onError);
}
我很乐意得到一些帮助,因为我什至不知道什么是 broken/missing,这是我第一次使用 websockets,我在网上找不到类似的问题。

由于您使用的是 spring 引导,因此您需要对所有工件使用相同的版本。
例如,在 pom.xml 中,您应该有类似这些行的内容:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.1.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-websocket</artifactId>
<version>2.1.1.RELEASE</version>
</dependency>
确保您使用的是相同版本的spring引导依赖项。
添加 pom.xml 后进行编辑:
以防万一,请在此处尝试 spring 初始值设定项:https://start.spring.io/ 以确保您拥有所有正确的版本。将生成的 pom.xml 与您的进行比较。
您似乎在使用不同的 spring 版本时弄乱了依赖项。
这个问题的罪魁祸首是-
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot</artifactId>
<version>2.2.6.RELEASE</version>
</dependency>
由于这种依赖性,您有 spring-core-5.2.5.RELEASE
。
日志显示您正在使用
spring-messaging-5.2.10.RELEASE
使用 StreamUtils copyToString 方法的版本,该方法是在 5.2.6 版本中添加的。
如果您确保使用 spring-core-5.2.10.RELEASE
版本,应该可以解决问题。
您应该使用 pom.xml 的属性部分。为 Spring 引导版本添加新的 属性。请注意 spring 引导 2.3.1 将拉取 spring 5.2.10.RELEASE 版本。
<properties>
<java.version>11</java.version>
<maven.compiler.source>11</maven.compiler.source>
<maven.compiler.target>11</maven.compiler.target>
<spring.boot.version>2.3.1.RELEASE</spring.boot.version>
</properties>
然后在 -
等依赖项中使用它
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot</artifactId>
<version>${spring.boot.version}</version>
</dependency>
您应该对所有 spring 引导启动程序依赖项执行类似的操作。另外删除那些显式 spring 依赖项,例如 spring-context
.
我 运行 遇到了同样的问题,但是无法移动到较新的 spring 引导版本。我找到的解决方案是将 spring-messaging 版本降级到 5.2.5.RELEASE(spring-websocket 也是如此)并且它有效。
