使用Websocket配置在tomcat上部署Spring Boot应用程序

Question

我有一个带有Spring websocket依赖关系的spring启动应用程序。该应用程序在我的Intellij IDE上运行良好，但在TC服务器上部署时，它无法启动应用程序。

我确实提供了tomcat服务器依赖项，app扩展了SpringBootServletInializer。

这是我的课程

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() + "!");
    }

}

其中一个Rest控制器

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，我在服务器日志上收到以下错误

Answer 1

我能够通过排除＆＃34; WebMvcAutoConfiguration.class＆＃34;来解决这个问题。来自应用程序的入门级。

@SpringBootApplication（exclude = WebMvcAutoConfiguration.class）

代码现在可以正常使用websocket。我能够收到来自websocket服务器的回复。
