springboot 配置websocket wss

以下是在Spring Boot中配置WebSocket wss的步骤：

1.在pom.xml文件中添加以下依赖：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-websocket</artifactId>
</dependency>
<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-websocket</artifactId>
</dependency>

2.创建WebSocketConfig类并添加@Configuration和@EnableWebSocket注解：

@Configuration
@EnableWebSocket
public class WebSocketConfig implements WebSocketConfigurer {
    // WebSocket配置代码
}

3.实现WebSocketConfigurer接口并重写registerWebSocketHandlers方法：

@Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
    registry.addHandler(myHandler(), "/websocket")
            .setAllowedOrigins("*")
            .withSockJS();
}

@Bean
public WebSocketHandler myHandler() {
    return new MyHandler();
}

4.创建MyHandler类并实现WebSocketHandler接口：

public class MyHandler implements WebSocketHandler {
    // WebSocket处理代码
}

5.在application.properties文件中添加以下配置：

server.port=8443
server.ssl.key-store=classpath:keystore.p12
server.ssl.key-store-password=changeit
server.ssl.keyStoreType=PKCS12
server.ssl.keyAlias=tomcat

6.使用keytool生成证书：

keytool -genkeypair -alias tomcat -keyalg RSA -keysize 2048 -storetype PKCS12 -keystore keystore.p12 -validity 3650

7.启动应用程序并访问wss://localhost:8443/websocket即可连接到WebSocket服务器。
