在Spring Boot中配置WebSocket,首先需要添加WebSocket相关的依赖,通常是`spring-websocket`库。以下是基本步骤:
1. **添加依赖**:在你的`pom.xml`或`build.gradle`文件中,添加Spring WebSocket的Maven或Gradle坐标:
```xml
<!-- Maven -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-websocket</artifactId>
</dependency>
<!-- Gradle -->
implementation 'org.springframework.boot:spring-boot-starter-websocket'
```
2. **启用WebSocket**:在Spring Boot主类或配置类中,启用WebSocket功能:
```java
@SpringBootApplication
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}
// 或者在配置类中:
@EnableWebSocketMessageBroker
public class WebConfig implements WebSocketMessageBrokerConfigurer {
// ...
}
```
3. **创建WebSocket处理器**:创建一个实现了`TextMessageHandler`或`BinaryMessageHandler`的类,它是实际处理客户端消息的地方。例如:
```java
@Component
public class ChatWebSocketHandler extends TextMessageHandler {
//...
}
```
4. **注册处理器**:在`WebConfig`中注册你的WebSocket处理器,使其监听特定的频道(room):
```java
@Override
public void configureMessageBrokers(MessageBrokerRegistry config) {
config.enableSimpleBroker("/topic");
config.setApplicationDestinationPrefixes("/app");
config.addHandler(chatWebSocketHandler, "/chat");
}
```
5. **客户端连接**:在微信小程序中,你可以使用WebSocket API发起连接请求,并处理服务器的响应和推送。
