当前java项目普遍使用两种方式集成Websocket,一种是依赖Tomcat,一种是springboot内置的,本文采用springboot内置方案。
前提:引入Websocket包
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-websocket</artifactId>
</dependency>
-
定义WebSocketConfig
@Configuration @EnableWebSocket public class WebSocketConfig implements WebSocketConfigurer { @Autowired private CustomWebSocketHandler customWebSocketHandler; @Override public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) { registry.addHandler(customWebSocketHandler, "/ws").setAllowedOrigins("*"); } }
2.定义WebSocketHandler
/**
* 创建一个WebSocket请求控制器,来处理websocket通信的对话服务
*/
@Slf4j
@Component
public class CustomWebSocketHandler extends TextWebSocketHandler {
@Override
public void afterConnectionEstablished(@NotNull WebSocketSession session) {
log.info("CustomWebSocketHandler.afterConnectionEstablished.对话服务的websocket连接成功,session={}", session);
// 在连接建立后发送消息到服务器(可选)
// session.sendMessage(new TextMessage("Hello, server!"));
}
@Override
public void handleTextMessage(@NotNull WebSocketSession session, TextMessage message) {
log.info("CustomWebSocketHandler.handleTextMessage.websocket接收到消息,session={},message={}", session, message.getPayload());
//在这里写自己的业务逻辑
}
@Override
public void handleTransportError(@NotNull WebSocketSession session, @NotNull Throwable ex) {
log.error("CustomWebSocketHandler.handleTransportError.对话服务的websocket连接异常,session={}", session, ex);
try {
if (session.isOpen()) {
log.error("CustomWebSocketHandler.handleTransportError.消息发送失败,websocket连接主动关闭,session={}", session);
session.close();
}
} catch (IOException e) {
throw new RuntimeException(e);
}
}
}
3.此时就算集成完毕了,本地客户端可以正常调用了,可以使用AiFox工具,个人觉得比postman更好用文章来源:https://www.toymoban.com/news/detail-808229.html
4.如果是正式环境使用了nginx,需要添加如下配置:文章来源地址https://www.toymoban.com/news/detail-808229.html
location /ai-service-center/ws {
proxy_pass http://localhost:30861/ws;
proxy_read_timeout 300s;
proxy_send_timeout 300s;
proxy_http_version 1.1;
proxy_pass_request_headers on;
proxy_buffering off;
proxy_cache off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
}
