使用 Websocket 配置通过 tomcat 部署 Spring Boot 应用程序

debugcn 发表于 Dev

DP3

我有一个具有 Spring websocket 依赖关系的 Spring Boot 应用程序。该应用程序在我的 Intellij IDE 上运行良好，但在通过 TC 服务器部署时，它无法启动应用程序。

我确实有提供的 tomcat 服务器依赖项，并且应用程序扩展了 SpringBootServletInializer。

这是我的课

主类

package hello;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

问候控制器

package hello;

import org.springframework.messaging.handler.annotation.MessageMapping;
import org.springframework.messaging.handler.annotation.SendTo;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.CrossOrigin;

@Controller
@CrossOrigin
public class GreetingController {


    @MessageMapping("/hello")
    @SendTo("/topic/greetings")
    public Greeting greeting(HelloMessage message) throws Exception {
        System.out.println("Received at controller level" + message.getName());
        //Thread.sleep(1000); // simulated delay
        return new Greeting("Hello, " + message.getName() + "!");
    }

}

Rest控制器之一

package hello;

import org.springframework.web.bind.annotation.*;

/**
 * Created on 4/19/2018.
 */
@RestController
public class NewRestTestController {
    @GetMapping("/test")
    public String testControl(){
        System.out.println("Request received");
        return "Rest Call tested successfully";
    }
}

Websocket 配置类

package hello;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.web.WebMvcAutoConfiguration;
import org.springframework.context.annotation.Configuration;
import org.springframework.messaging.simp.config.MessageBrokerRegistry;
import org.springframework.web.bind.annotation.CrossOrigin;
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()
@CrossOrigin(origins = "*")
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {

    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.enableSimpleBroker("/topic");
        config.setApplicationDestinationPrefixes("/app");
    }

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/websocket").setAllowedOrigins("*").withSockJS();
    }

}

当我在 TC 服务器上部署应用程序时，服务器日志出现以下错误

DP3

我能够通过从应用程序的入门类中排除“WebMvcAutoConfiguration.class”来解决该问题。

@SpringBootApplication(exclude = WebMvcAutoConfiguration.class)

该代码现在可以在 websocket 上正常工作。我能够从 websocket 服务器接收响应。
