SpringBoot webscoket基本配置

一、pom.xml文件配置
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
	<modelVersion>4.0.0</modelVersion>
	<groupId>com.hxkj.websocket</groupId>
	<artifactId>springboot-websocket</artifactId>
	<version>0.0.1-SNAPSHOT</version>

	<!-- Inherit defaults from Spring Boot -->
	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>1.4.0.RELEASE</version>
	</parent>

	<!-- Add typical dependencies for a web application -->
	<dependencies>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
		</dependency>

		<!--Mysql -->
		<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
		</dependency>
		<!-- datajpa -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-data-jpa</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-configuration-processor</artifactId>
			<optional>true</optional>
		</dependency>
		<!-- websocket -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-websocket</artifactId>
		</dependency>

		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-thymeleaf</artifactId>
		</dependency>
	</dependencies>

	<!-- Package as an executable jar -->
	<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>
</project>

可能需要翻墙

二、application.java启动配置、

@EnableTransactionManagement
@SpringBootApplication
@ServletComponentScan//servlet的扫描
public class Application extends SpringBootServletInitializer {

	private static Logger logger = Logger.getLogger(Application.class);

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

	public static void main(String[] args) {
		SpringApplication.run(Application.class, args);
		logger.info("============= SpringBoot Start Success =============");
	}

}

三、websocket基本配置


@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {

	@Override    
    public void registerStompEndpoints(StompEndpointRegistry registry) {        
        registry.addEndpoint("/socket").withSockJS();       
    }    
	
    @Override    
    public void configureMessageBroker(MessageBrokerRegistry registry) {  
        registry.enableSimpleBroker("/topic");      
        registry.setApplicationDestinationPrefixes("/app"); 
    }

}

四、controller配置


@Controller
public class GreetingController {

	@Autowired
    private SimpMessagingTemplate simpMessagingTemplate;  
	
	@RequestMapping("index") 
	public String index(){
		return "index";
	}
	
    @RequestMapping("/helloSocket")    
    public String helloSocket(){        
        return "hello/index";    
    }  
    
    @MessageMapping(value="/change-notice")    
    @SendTo("/topic/notice")
    public void greeting(String value){
    	System.out.println("session:"+"		value:"+value);
        this.simpMessagingTemplate.convertAndSend("/topic/notice", value);    
    }
}
