spring boot 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);
}
}
