springboot-websocket
关于Spring Boot和OkHttp3的WebSocket,你可以按照以下步骤进行配置和使用:
1. 首先,添加必要的依赖。在你的`pom.xml`文件中添加以下依赖:
```xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-websocket</artifactId>
</dependency>
<dependency>
<groupId>com.squareup.okhttp3</groupId>
<artifactId>okhttp</artifactId>
<version>版本号</version>
</dependency>
```
2. 创建一个WebSocket配置类,用于配置WebSocket相关的Bean和处理器。
```java
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.socket.config.annotation.EnableWebSocket;
import org.springframework.web.socket.config.annotation.WebSocketConfigurer;
import org.springframework.web.socket.config.annotation.WebSocketHandlerRegistry;
import org.springframework.web.socket.handler.TextWebSocketHandler;
@Configuration
@EnableWebSocket
public class WebSocketConfig implements WebSocketConfigurer {
@Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
registry.addHandler(myWebSocketHandler(), "/websocket").setAllowedOrigins("*");
}
@Bean
public TextWebSocketHandler myWebSocketHandler() {
return new MyWebSocketHandler();
}
}
```
3. 创建一个WebSocket处理器,实现自`TextWebSocketHandler`。
```java
import org.springframework.web.socket.TextMessage;
import org.springframework.web.socket.WebSocketSession;
import org.springframework.web.socket.handler.TextWebSocketHandler;
public class MyWebSocketHandler extends TextWebSocketHandler {
@Override
protected void handleTextMessage(WebSocketSession session, TextMessage message) throws IOException {
// 处理接收到的消息
String payload = message.getPayload();
// 发送消息给客户端
session.sendMessage(new TextMessage("Hello, " + payload + "!"));
}
}
```
4. 在你的Spring Boot主类上添加`@EnableWebSocket`注解。
```java
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
@SpringBootApplication
@ComponentScan(basePackages = "com.xy.admin.websocket")
public class YourApplication {
public static void main(String[] args) {
SpringApplication.run(YourApplication.class, args);
}
}
```
5. 创建一个前端页面,用于调用WebSocket服务。你可以使用以下代码作为参考:
```html
<!DOCTYPE html>
<html>
<head>
<title>WebSocket Example</title>
<script>
var websocket = null;
// 判断当前浏览器是否支持WebSocket
if ('WebSocket' in window) {
websocket = new WebSocket("ws://localhost:8080/websocket");
} else {
alert('当前浏览器不支持WebSocket');
}
// 连接发生错误的回调方法
websocket.onerror = function () {
setMessageInnerHTML("WebSocket连接发生错误");
};
// 连接成功建立的回调方法
websocket.onopen = function () {
setMessageInnerHTML("WebSocket连接成功");
};
// 接收到消息的回调方法
websocket.onmessage = function (event) {
setMessageInnerHTML(event.data);
};
// 连接关闭的回调方法
websocket.onclose = function () {
setMessageInnerHTML("WebSocket连接关闭");
};
// 监听窗口关闭事件,当窗口关闭时,主动去关闭websocket连接,防止连接还没断开就关闭窗口,server端会抛异常。
window.onbeforeunload = function () {
closeWebSocket();
};
// 将消息显示在网页上
function setMessageInnerHTML(innerHTML) {
document.getElementById('message').innerHTML += innerHTML + '<br/>';
}
// 关闭WebSocket连接
function closeWebSocket() {
websocket.close();
}
// 发送消息
function send() {
var message = document.getElementById('text').value;
websocket.send(message);
}
</script>
</head>
<body>
<div id="message"></div>
<input type="text" id="text" />
<button onclick="send()">发送</button>
</body>
</html>
```
以上就是关于Spring Boot和OkHttp3的WebSocket的配置和使用方法。你可以根据自己的实际需求进行相应的调整和扩展。
